SCIENCE & TECHNOLOGY LOG:
Thursday, July 22 (continuation): After my bout with motion sickness, I felt a lot better so I decided to finish my shift. Around 1400 (2pm) upon returning to the Acoustic lab suddenly I smelled the fish:they were trawling for Pollock! I rushed to the wet lab to find Darin and Story, my fellow Teacher at Sea, and a young scientist named Kathy Hough already in full gear, surveying the Pollock. The catch was coming down a chute and spilling over a conveyor where the fish was sorted out by sizes. The targeted size Pollock was placed in crates to record the weight on a digital scale, while the rest, together with any giant jelly fish, or Northern Sea Nettle (Chrysaora melanaster) caught in the net were return overboard. The next part of the survey involved dissecting each fish using a scalpel, making a cut across the left side of the underbelly in order to determine the sex and the content of the stomach. There was a large chart showing pictures of the way the female reproductive organs or ovaries and the male testes looked like at each level or size from 1 to 4. The males were named "blokes" and the females "sheilas" (I believe these to be Australian terms). After the dissection the length of each fish was recorded automatically using a white measuring board with a yellow metric ruler featuring a magnetic strip. The final step involved selected specimens getting a cut above their heads in order to remove two tiny ear bones or "Otolith" that every bone fish have. They are used to determine the growth of the fish, and together with samples of stomach content they were preserved and placed in a freezer to be sent to a NOAA laboratory in Seattle for further analysis.
PERSONAL LOG:
Working with the Pollock Survey has really hit home. All this fish made me think about "Sharky" our Brook Trout resident born 3 years ago in our cold water aquarium at MS319, as part of "Trout in the Classroom" a program where New York city students learn about conservation by raising trout from eggs to fingerlings, or juvenile size, and then they get to release them in a cold water stream upstate New York. Trout is another fish that is part of the Alaska ecosystem, living and spawning in streams along the coast. The trawling reminded me of when we cast our Seine nets on the Harlem River, as part of our Environmental Education after school program, in order to identify the fish and collect the data, just like the survey. I made a great connection when Darin, the young scientist working with us on the Pollock survey, told me that Pollock is called "Bacallao" in Portuguese. This reminded me that back in New York City, I noticed that for the past years in every "bodega" (spanish grocery store) the packaging containing Bacalao nowadays say Pollock instead of what traditionally used to be Cod fish. Apparently there is an specie of Atlantic Pollock that has been historically consumed in Europe and in the Mediterranean countries of Portugal and Spain, so it is no surprise that we have incorporated Bacalao as part of the traditional cooking of the Dominican Republic. Every self-respecting Dominican knows that Bacalao is a staple of Dominican cuisine. I never liked fish as a child, and I remember that Bacalao was the only fish I actually enjoyed eating until this day, well seasoned in tomato sauce and onions, accompanied with rice beans or with yucca. This reminds me of another fish part of the dominican culinary culture: a form of dried, smoked fish (very smelly) known as "Arenque". This fish, widely sold in bodegas and open markets is usually cooked in a paella style rice called "locrio". I had a hunch that Arenque was Spanish for Herring, another fish like Pollock, found in the waters of the Bering Sea. After a little research I found out that indeed Arenque and Herring were the same. Arenque is the Spanish word for the Atlantic Herring (Clupea harengus), commonly fished and consumed in Spain, Portugal, and South America. Humm... Arenque=harengus (Latin), whence the English name Herring. Eureka! Days later some Pacific Herring was caught in one of the trawls and I noticed it had large shiny scales, dark blue on the top, and silver ones in the underbelly. Some where cooked for diner that night and the meat was very tasty, looking like... Arenque.
Animal Species Observed:
Northern Sea nettle jellyfish, Pacific Herring (Clupea pallasi), Walleye Pollock (Theragra Chacogramma)
New Vocabulary:
Arenque, Bacallao, Bodega, Brook Trout (salvelinus fontanelis), Herring, Otolith, Seine Net, Scalpel



"Monitoreo del Bacallao"

El mareo no me permitio participar en la pesca de hoy, pero desde que me senti mejor fui directo a la cubierta donde una grua de carga habia depositado los peces en una rampa de aluminio hacia el Laboratorio Humedo. Ya adentro encontre a Story, mi colega maestra, Darin, y una joven cientifico llamada Kathy, que ya estaban trabajando con los pescados. El proceso consistia en separar el Pollock de otras especies como el Herring, y la Medusa Gigante, que despues de tomarse el peso eran arrojados por la borda. El Pollock era pues separado por sexo, entre "Blokes" machos, y "Sheilas", hembras (terminos australianos), y esto se hacia por medio de diseccion, donde tambien se analizaba el contenido del estomago, usando un poster con fotos de los organos internos del Pollock a diferentes edades como guia.

Luego de la diseccion procedimos a medir cada uno de los pescados, Story los machos, y yo las hembras, usando una tabla blanca con una cinta metrica amarilla, que contenia una cinta magnetica. Cada pescado era medido automaticamente al colocarse cuidadosamente a lo largo de la cinta metrica, y el conteo era registrado en una pantalla de computador con el nombre del cientifico. Me senti muy orgulloso al ver mi nombre como el cientifico de turno! El paso final era el de remover el "Otolith" o hueso del oido, usado para medir el crecimiento del pez, que junto a el contenido del estomago se preservaba para enviarse a los laboartorios de NOAA en Seattle. Tanto pescado me hizo pensar en "Sharky" la trucha mascota que hemos estado criando en el aquario de la escuela como parte del programa "Truchas en El Salon de Clases". Tambien me recorde de cuando mis estudiantes tiran las redes de pesca para estudiar las especies acuaticas del Rio Harlem, como parte del programa de Educacion Ambiental que dirijo en la escuela MS319. Tambien estudiando el Pollock, aprendi que los portugueses le llaman "Bacallao", casi identico a la palabra "Bacalao", que es como lo llamamos en Republica Dominicana. Otro pez que junto al Bacalao son parte de la cocina tradicional dominicana es el Arenque. Yo tenia una corazonada que el Arenque era la misma palabra de un pez que en Ingles se llama "Herring", tambien muy abundante en Alaska. Despues de hacer una investigacion, Eureka! resolvi el misterio. Arenque es la palabra usada para referirse al Clupea harengus o Arenque Atlantico, de donde viene tambien el termino Herring=harengus=Arenque. Todo Dominicano que se respeta sabe que el Bacalao y el Arenque son parte de la comida tradicional dominicana.

SCIENCE & TECHNOLOGY LOG:
The purpose of this mission aboard the Oscar Dyson is for a team of scientists to conduct a survey of the Bering Sea Walleye Pollock population, in oder to help the government establish sustainable commercial fishing quotas that will allow to manage a healthy population of this abundant, but yet fragile species. In order to carry the Pollock survey it is necessary to perform a combined Acoustic -Trawl Survey where acoustic data is collected along a line transect and then a Trawl (net) is used to catch a sample quantity of the fish observed in the acoustic data.
In the Acoustic Lab there are a number of video monitors displaying several screens. Taina Honkalehto, the Chief Scientist of the Oscar Dyson explained to us how the acoustic sonar operates. First the acoustic survey relies on Sonar technology where it sends an acoustic "ping" powerful enough to detect fish at any depths. It travel back and forth between the bottom and the surface of the ocean, and its signature then registered on a video screen, allowing us to "see" where the fish are and the precise location. One screen shows an actual graph, or "echogram", displaying several layers at different depths in colors ranging from gray, blue, green, yellow, orange to red. The dark red color represented the ocean floor, and the green/blue dots represented the fish. The darker the color, the more dense were the objects. Another sceen showed the location of the ship on a Nautical Topographic Map, including a red line showing transects (line routes) followed by the ship., as well as icons showing the points where the fish has been detected along the way. Taina then uses this constant information to decide how to instruct the bridge into when where to position the ship in order to launch the trawl net. The trawl net used is known as an Aleutian Wing Trawl (AWT). It is equipped with specialized sensors that show in the video monitor where the fish are in relation to the net. Once the trawl is finished the net is then hauled back and the contents spread on deck for sorting out and identification. Target species such as the Walleye Pollock will be separated to be measured and weight then released overboard. Some of the catch will be kept for dissection to determine the sex, and to determine the age by studying the Ear bone or Otholith, that registers the gowth of the fish by marking each year with a dark ring, just like the growth rings on a tree. The otolith, stomach contents, and sample fish are carefully placed in vials, mesh and ziploc bags to be sent to NOAA's Alaska Fisheries Science Center in Seattle for laboratory analysis. all this information will tell us how healthy is the Pollock population o the Bering sea, and help determine commercial fishing quotas for next year's fishing season.
PERSONAL LOG:
I could not help to think about the amount of technology involved in the Pollock survey. I am pretty sure that Mr.Sanchez, my school technology teacher would be excited to see all the servers, CPUs, monitors, and all the coputer harware and gear used around here onboard the Oscar Dyson. I believe that the middle school students of the Maria Teresa Mirabal school MS319 will be right at home, since they are accustomed to used technology as part their everyday school work. From getting their password to log on into the school website network, using Netbooks for interactive podcast lessons, to taking online reading comprehension quizzes, these are part of a technology rich learning environment. Technology literacy is basic for a 21st Century education. But technology alone is not enough if we don't tech the kids how to apply it in the real world. One example of the importance of using mathematical skills in the real world is best demonstrated in the Acoustic survey when calculating the estimated size of the fish that appears as dots on the Acoustic radar screen. The sonar software allows to isolate the fish by scanning a selected area of the monitor display and calculating the average decibel (sound unit) value per dot representing a fish. Knowing this value we can replace it in a given formula and easily calculate the approximate size of the fish in order to start trawling.
VOCABULARY:
Aleutian (Alaska native group), Dissection, Decibel, Nautical Topographic Map (underwater map of the ocean floor), Otolith, Transect

"Tecnologia en Alta Mar" El proposito de la Mision abordo del Oscar Dyson es la de tomar un muestreo del Pollock o Bacalao para poder determinar que tan robusta esta su poblacion, a fin de poder determinar las cuotas apropiadas a ser dictadas a las flotas de pesca comercial. Para poder hacer este muestreo es necesario el uso de tecnologia de Sonar Acustico en combinacion con el uso de la Red de Arrastre. Todo comienza en el Laboratorio Acustico donde un numero de pantallas de monitor muestran diferentes imagenes. Taina Honkalehto, la Cientifico en Jefe del Oscar Dyson, nos explico que la tecnologia de sonar consiste en enviar un "ping" acustico que es lo suficiente poderoso para viajar de la superficie al fondo del mar de ida y vuelta, penetrando las capas mas profundas. La onda acustica que es reflejada es pues registrada en las pantallas permitiendonos ver una imagen de la ubicacion de los peces, y la precisa profundidad. Una pantalla nos muestra una grafica en tiempo real con lineas de diferentes colores que van del gris, azul, verde, amarillo, hasta el rojo que representa el fondo del mar. Otra pantalla nos muestra un Mapa Topografico Nautico que incluye una linea roja mostrando la linea de transeccion o el curso que sigue la nave. Con toda esta informacion Taina puede instruir al puente sobre que ruta de navegacion debe tomar la nave a fin de hacer la pesca. La red de Arrastre Aleutina, empleada en el muestreo, esta equipada con sensores especiales que indican en la pantalla la ubicacion de los peces en todo tempo. Realmente tienen la pesca totalmente calculada a lo mas minimo! Tan pronto se termina la pesca, el contenido de la red es pues depositado en la cubierta donde los peces seran separados para ser medidos y disecados a fin de averiguar el sexo y la edad. Muestras del contenido del estomago, y especimenes seran recogidos a fin de enviarlos a los laboratorios de NOAA en Seattle para determinar si la poblacion estara optima para la peca de la proxima estacion.

Science & Technology Log:
Thursday, July 22: After a night of swinging and swaying from the waves at high seas, I am somewhat used to it already. Today is the start of my new shift from 0400 in the morning until 4:00 pm in the afternoon, 12 hours on, 12 hours off. Since yesterday we left the continental shelf and we are heading to deeper waters. There was a scheduled trawl to be done early this morning, but the Acoustic Lab reported no fish at all on the screens. As part of the survey it is necessary to perform a CTD launch every morning at sunrise. CTD stands for Conductivity, Temperature, and Depth, explained Darin Jones, one of the young scientists in charge of the Pollock survey. The CTD unit is made up of a series of bottles used to collect water samples at different depths, and also includes remote sensors to collect data such as sea temperature, salinity, depth, water pressure, and fluorescence. Fluorescence is the presence of Chlorophyll in the water which depends on the amount of sunlight that penetrates the ocean, indicating the presence of Phytoplankton (algae and other microscopic plants). They rely on sunlight to produce the energy that zooplankton growth is dependent upon. Zooplankton is the foundation of the Bering Sea food chain, since is made up of krill, small shrimp like crustaceans that are the primary source of food for commercial fish such as Pollock, Cod, Salmon, and pretty much any other fish in the North Pacific Ocean. As the CTD is dropped the ship needs to stop in order lower the unit, which is attached by cables to an A-Frame crane, including one to transmit data. The CTD can only be used to depths of 600 meters, so another device called the XBT for Expendable Bathy-Thermograph (for depth and temperature) is used for depths up to 700 meters. It can also be launched manually while the ship is in motion, and data is transmitted through a thin copper wire that splits, hence the name "Expendable". Once the CTD is hauled back onto deck, the water bottles are drained and samples taken for dissolved oxygen (DO) analysis. DO is sequestered using chemicals that react with the oxygen taking a solid form that preserves it for lab analysis.
Personal Log:
Last night I took motion sickness pills to keep me from getting seasick. After breakfast weather got really bad, with waves up to 6 feet, battering the Oscar Dyson. These conditions, combined with a heavy breakfast, made feel really dizzy, and next I know I was throwing up. My roommate, Vince Welton, who is also the ship's tech guy, got me some very tasty saltine crackers, and medication, that help me feel better. I laid down on my bunk bed and doze off while listening to some Jazz by Michel Camilo. While trying to rest the waves were crashing into the hull of the ship with a loud noise, while the ship kept going up and down. I was thinking about how seafarers of the past and the conditions aboard were so much different than today. Ocean going trips now are made much easier by the technology and modern amenities commonly found on board. Staterooms with bath, galleys or kitchens fully equipped with fridge, microwave oven, and entertainment rooms with flat TVs and DVD players are the norm. I kept thinking that the next 2 weeks on board the Oscar Dyson will be a lot like space travel, will all the walking up and down stairs from deck to deck, closing of hatches, and not been able to step outside the ship for a walk until reaching port. The connection I can make about the CTD is that it reminds me a lot of the citizen science data collection and water quality monitoring I conduct with my students after school on the Harlem River, as part of "A Day in the Life of the Hudson River" a yearly event sponsored by NYSDEC (NY State Dept of environmental Conservation) and Columbia University Lamont-Doherty Laboratory. just like in the CTD we collect samples of water from the river to test for Dissolved Oxygen, Chlorophyll, PH, Salinity, Nitrates, plus soil samples from the mudflats. When we collect the chlorophyll samples we use the same methods just as it's done on the Oscar Dyson, squirting the water through a circular paper filter until it turns brownish. I am planning a lesson for next school year called "NOAA in the Classroom:Student CTD Activity" where using a student water sampling bottle my Environmental Science Club class will collect water from the Harlem River at different depths with the help of our wooden boat "Boca Chica" built after school. We test the samples for DO, Salinity, PH and other protocols using a LaMotte water quality test kit to monitor the health of the Harlem/Hudson River Estuary. This data will be reported to the GLOBE.gov Program website to be used by scientists and schools all over the world. My middle school MS319 is a GLOBE Program partner school, and also we will be reporting data from our new Wireless Weather Station. I strongly believe that students learn science by doing science!
"Navegando en Alta Mar"
Jueves, 22 de Julio: Hoy comence my primera guardia de las 0400 am a las 4pm. Desde que zarpamos del puerto de Dutch Harbor hacia aguas profundas me habia librado del mareo, pero finalmente me agarro.

El mal tiempo de hoy temprano, con violetas olas que golpeaban la nave de hasta 18 metros, mas un desayuno muy pesado me provocaron unas nauseas que termine en mi camarote vomitando y tirado en la cama. Despues de tomarme una medicina y de comerme unas galletitas de soda, me tome una siesta y me levante mucho mejor. El Sonar Acustico de la nave no detecto presencia de peces por lo que fui a ver el lanzamiento de un CTD o unidad de Conductividad y Profundidad Termal. El CTD contiene botellas para recoger muestras de agua y sensores para medir la temperatura y salinidad del mar hasta 600 metros. Para medidas mas profundas de hasta 700 metros se usa una unidad manual desechable llamada XBT. Ambas unidades son usadas para obtener datos cientificos como el nivel de Oxygeno disuelto, Salinidad, Profundidad, y Florescencia (nivel de clorofila), la ultima es muy importante pues refleja la abundancia de algas microscopicas de las que depende el Zooplankton. El zooplankton esta compuesto de minusculos crustaceos que son la base del ecosistema alimenticio del Estrecho de Bering, del cual dependen especies comerciales como el Bacallao, Salmon y Arenque, asi como casi toda especie de pez en el Oceano Pacifico Norte. El uso del CTD es muy parecido al trabajo que hago con mis estudiantes analizando las aguas del Rio Harlem. Estos jovenes cientificos tambien toman muestras de agua y practican analisis de campo para Oxygeno disuelto, PH, Nitratos, Salinidad e incluso pruebas de Clorofila, como parte de un evento anual llamado "Un dia en la Vida del Rio Hudson" . En este evento organizado por el Laboratotio Lamont-Doherty de la Universidad Columbia, y el Depto de Conservacion del Estado de NY, participan escuelas a todo lo largo del Rio Hudson, recaudando datos cientificos sobre el rio. Pensamos usar a "BOCA CHICA",un bote de madera que armamos de tarde, para una practica de CTD tomando muestras de agua del rio, analizarlas, y reportar los datos en el internet. Tambien mis estudiantes de la Escuela Intermedia Maria Teresa Mirabal Ms319, de origen dominicano en su mayoria, aprenden ciencia ambiental al tomar datos de la Estacion Metereologica ubicada en el techo de la escuela. Ellos reportan los datos via internet en la pagina web del Programa GLOBE.gov, para ser usados por cientificos y estudiantes por todo el mundo.

Science and Technology Log:
Yesterday afternoon we had a Fire/Emergency drill, just like we do in school. Safety is definately big around here. Everywhere you look there is an orange sign for an EEBD (Emergency Escape Breathing Device), to be used in case of a fire,to avoid intoxication from breathing the smoke. Fire is the number one enemy in a ship, and it can have disastrous consequences at sea. For the fire drill we had to follow a path leading to a safe room where we had to be accounted for. Fire stations are in every corner with Fire Hoses, and even Fire Axes. Next we had to do an Emergency drill where we had to practice abandoning ship. I had to grab my assigned Immersion suit, or "Mustang suit", also known as a "Gumby suit", which is an orange jumpsuit, made of neoprene (the material used in drysuits or diving suits). It is supposed to keep you warm and alive in the event you have to abandon ship and hit the icy waters of the Bering Sea. I had to practice putting on the cumbersome but necessary safety gear. Everyone is issued one that has to be kept in their staterooms. I had to pack it again and put it back in it's original bag after I finished trying on. As part of the emergency drill we also had to gather around the ship's Life Rafts, that where contained inside a set of 3 white canisters on both sides of the ship (Port (right), and Starboard (left) ). I was surprised to see my name on the evacuation plan assinged to Life rafts 2-3. Each life raft can hold up to 20 people inside, and many more, until rescue arrives. I noticed that aboard the ship chairs, tables, cabinets and pretty much anything that can get loose during bad weather are safely anchored to avoid falling off. There are safety signs everywhere you go reminding you to be ready at all times. Also safety is No 1 whenever working on the deck near the water, from the use of a PFD (personal Flotation Device), a hard hat, due to cranes and heavy duty cables, to a safety harness to be anchored to the boat. Eye wash emergency stations are everywhere, as well as signs telling you to use hand sanitizer at all times.

Personal Log:
Safety first: Just like in school, the possibility of a fire can lead to disaster and tragedy. It is a serious matter that we should all be prepared for. Fire drills in school, like in the Oscar Dyson, help us get familiar with our nearest exit starcase, and to know a safe place to gather up away from the fire, just like when we go across the street from our school during a drill. Also as a member of the Washington Heights, Manhattan North CB12 CERT (Community Emergency Response Team), it is my job to help educate the community at large about fire emergecy preparedness awareness. Fire is the #1 emergency affecting buildings in New York City and every resident is at risk of been affected. Since 9-11, NYC OEM has been promoting emrgency awareness by educating and getting the public involved in emergency awareness ranging from fire, heat waves, to hurricane emergencies. I encourage everyone to visit ReadyNY.org and Ready.gov to learn more about protecting yourself, family and neighbors in case of an emergency. Ayer tuvimos una practica de Evacuacion de emergencia y de Incendio. Practicamos siguiendo el Plan de Evacuacion en caso de fuego reuniendonos en un lugar designado (en este caso el salon de Conferencias). Tambien practicamos el abandonar la nave, donde teniamos que ponernos los Trajes de Supervivencia o de Inmersion, requeridos por ley. En caso de que al abandonar la nave nos protegerian de las gelidas aguas del Estrecho de Bering manteniendonos secos y abrigados si llegaramos a caer en el mar. Me sorprendi mucho de ver mi nombre en la lista de evacuacion ya asignado a una de las Balsas Salvavidas, de la nave. Hay dos juegos de 3 balsas en ambos lados de la nave (Babor o derecha, y Estribor o izquierda) con capacidad para 20 personas. La seguridad es No 1 abordo del Oscar Dyson, con letreros en todas partes indicando desde el uso de Chalecos Salvavidas, Trajes de Inmersion, hasta estaciones de emergencia, con mangueras y hachas de incendio. Asi como en la escuela y en los edificios todos debemos estar educados en que hacer en caso de incendio, que es la emergencia #1 en la Ciudad de Nueva York.

Science and Technology Log:
Yesterday, Tuesday July 20, we finally left Dutch harbor, once all the delayed scientific equipment arrived. I was later told that it included some new and sophisticated technology to track and measure fish underwater. We climbed up to the "flying bridge" at the very top of the ship to see the view of Dutch harbor behind us and the open ocean ahead. After that we came down to the bridge where Acting Executive Officer XO Sarah Duncan, Ensign Amber Payne, and Buddy Gould from the Deck Department gave us a tour of the bridge. They explained that the panels of navigational instruments used to sail the ship included Radar screens, to detect any vessels or ships in the proximity, one for long range, and another for short range, showing any ships close by. The screens show the many readings from instruments on board such as wind speed (in knots), Wind direction (in degrees), Latitude, Longitude, and Air Pressure (in millibars). Next we received a demonstration in how to chart a course using the Electronic chart. I was surprised to understand the navigational terminology, (Iguess my Basic Sailing class is paying off), such as true wind, leeward, aft, forward, et...
I asked if they still used paper Nautical Charts and the answer was yes, they use them to plot the course of the ship using pen, ruler, and compass. I was surprised to know that even with all this technology even though the ship course and navigation is done completely electronically, they still rely on pen and paper charts as back up! On the bridge were also two scientists fro the US Fish and Wildlife service working on Seabird research, as part of the Bering Sea Integrated Ecosystem Project, a multidsciplinary study that is looking at how climate change is affecting the ecosystem of the Bering Sea. liz and Marty were both working from the bridge with binoculars, observing and counting all seabirds within 300 meters from the ship. armed with a laptop computer connected to the ship's navigational system they were able to count and input the GPS location (latitude/longitude) of every sighting of a seabird, and plot a GIS graph in real time. I found this to be really cool! We saw seabirds found on the Bering sea such as Black-footed Albatross, Northern Fulmar, Tufted/Horned Puffin, Fork-tailed Storm Petrel, and Thick-bill Murre.

Personal Log:
Today is Day 4 of the mission and so far I have done pretty well in terms of motion sickness. A calm sea has been a great factor and has allowed me to get adjusted to life at sea. I am surprised to find myself at home in my my bunk bed, and haven't had any difficulties sleeping at all, though I do miss my bed. The long schedule from 0400 to 1600 (4pm) full of activities has been of help keeping me busy. The food is great thanks to Floyd the master cook with a variety of international food and home baked pastries. I was also impressed by the international collaboration in this mission, with two Russian scientists on board conducting research on the fisheries of the Bering Sea since part of the transects or line passess done by the Oscar Dyson cover Russian territorial waters as well.

PERSONAL LOG:
Whoever said that "getting there is half the fun"? On Saturday July 17,2010 I took a Jet Blue flight from JFK airport bound to Seattle, Washington. We landed at about 6pm Eastern time, and connected to Anchorage, Alaska on Alaska Air. I had to stay overnight to catch the next day a plane to Dutch Harbor, mi final destination. It was very estrange that night since the sun was out up until about 12 midnight, so I had to trick my body into going to sleep by closing all curtains and darkening the room. The next day I flew on Penair, a commuter airline that uses small Saab turboprop planes. After stopping over King Salmon island for refueling we flew to Dutch Harbor,in the Island of Unalashka. I was amazed at the beautiful bay surrounded by glacial carved mountains and a snow covered peak volcano. I was picked up at the airport by Story Miller, my fellow teacher at sea, who lives in Dutch Harbor. We drove around a kind of frontier town,surrounded by fishing boats, crab pods, and cannery factories. The smell of fish tells you that fishing is the biggest industry and is part of the general culture around here. Finally upon entering a cargo entrance leading to a comercial pier,there she was:the Oscar Dyson. This NOAA ship was named after a fioneer comercial fisherman who championed sustainable fisheries in Alaska for many years. After setting up my gear in my stateroom, I was invited to take a short hike up what was going to be a 1,200 feet mountain known as "Ballyhoo"with, with one of Dyson's junnior NOAA Corps Officer Ensign Dave Rodziewicz. Upon reaching the summit, in about hour and half, which left me with sored legs, I was met with a 360 degree view of Dutch Harbor. The mountain was covered with moss and flowers and I decided to call it a day and just below the clouds were passing by. All this surreal and wonderful view made me forget my aching legs. It was all worth it. Afterwards we came down the mountain and just when the sun was coming down around midnight I fell asleep in my bunk bed. Good night! El pasado sabado 17 de Julio viaje en Jet Blue de NY hacia Anchorage, Alaska con escala en Seattle, Washington para el siguiente dia tomar un vuelo en un avion turbo-helice de la linea Penair hacia Dutch Harbor. Tan pronto llegue al barco de la NOAA Oscar Dyson deje mis cosas en mi cuarto y me fui a una caminata de campo. Lo que no me imagine era que iba a subir por una loma de cas 1,200 pies, con una vista increible en la cima. Lo mas raro fue el acostumbrarme a la luz solar de casi 24 horas, pues he tenido que cerrar las cortinas de my camarote para poder conciliar el sueno. Bueno nos vemos luego, Ciao!
