Science and Technology Log

We are on Day II of our travels to get to our first sampling station located in the SE Bering Sea.  We will begin our fishing operations today!  We have had decent weather thus far although we did just go through Unimak Pass (see picture below of location) which is a narrow strait between the Bering Sea and the North Pacific Ocean.  This passage offered a time of heavier seas.  I’m guessing that like any strait, the currents may become more funneled and the seas “confused” as they squeeze through this area.  It’s kind of analogous to it being more windy in between buildings of a major city vs. suburbia as the wind is funneled between skyscrapers.  I also imagine this to be a popular crossing for marine mammals as well.

Interesting to think that both marine mammals and humans use this passage to both get to the same things: a food source and a travel route.  It’s a migratory “highway” for marine mammals, and a heavily-trafficked area for humans in international trade and commercial fisheries.

Anyway, the Bering Sea is a very unique body of water. It really is the way that I imagined it.  It is as though you are looking through a kaleidoscope and the only offerings are 1000 different shades of grey.  It is rainy, foggy, and windy.  I can appreciate how this sea has been the graveyard for so many souls and fishing vessels in the past who have tried to extract the bounties it has to offer.

As of Wednesday, the 24th, we have finished 4 stations of the 30 that have been planned for Leg I of this study (Leg II is of similar duration and goals).  I was involved with helping the oceanographic crew with their tasks of collecting and evaluating various parameters of water chemistry.  To do this, an instrument called a “CTD”– an acronym for Conductivity, Temperature, and Depth — is lowered.  This instrument is the primary tool for determining these essential physical properties of sea water.  It allows the scientists to record detailed charting of these various parameters throughout the water column and helps us to understand how the ocean affects life and vice-versa.

One aspect that I found very interesting is the analyzing of chlorophyll through the water column.  All plant life on Earth contains the photosynthetic pigment called chlorophyll.  Phytoplankton (planktonic plants) occupy the photic zone of all water bodies.  Knowing that we live on a blue planet dominated by 70% coverage in water, we can thank these phytoplankton for their byproduct in photosynthesis, which is oxygen.  Kind of strange how you often symbolize the environmental movement with cutting down of the rainforests and cries that we are eliminating the trees that give us the air we breath.  This is true, but proportionately speaking, with an ocean-dominated sphere, we can thank these phytoplankton and photosynthetic bacteria for a large percentage of our oxygen.  Additionally, being at the base of the food chain and primary consumers, these extraordinary plants have carved a name for themselves in any marine investigation/study.

The procedure to measure chlorophyll involves the following:  water from the Niskin Bottles (attached to the CTD, used to “capture” water at select depths) is filtered through different filter meshes and the samples are deep-frozen at -80F.  To analyze chlorophyll content, the frozen sample filter is immersed in a 90% solution of DI (Distilled Water) and acetone which liberates the chlorophyll from the phytoplankton.  This is then sent through a fluorometer.

Fluorescence is the phenomena of some compounds to absorb specific wavelengths of light and then, emit longer wavelengths of light.  Chlorophyll absorbs blue light and emits, or fluoresces, red light and can be detected by this fluorometer.

Amazing to think that with this microscopic plant life, you can extrapolate out and potentially draw some general conclusions about the overall health of a place as large as the Bering Sea. Oceanographic work is remarkable.

Personal Log

The crew aboard the Oscar Dyson have been very accommodating and more than willing to educate me and take the time to physically show me how these scientific investigations work.  I am very impressed with the level of professionalism.  As a teacher, I know that most often, the best way to teach students is to present the material in a hands-on fashion…inquiry/discovery based.   This is clearly the format that I have been involved in while in the Bering Sea and I am learning a tremendous amount of information.

The food has been excellent (much better than I am used to while out at sea).  The seas have been a bit on the rough side but seem to be settling down somewhat (although, I do see a few Low Pressure Systems lined up, ready to enter the Bering Sea…..tis the season).  Veteran seamen in this area and even in the Mid-Atlantic off of NJ, know that this is the time of year when the weather starts to change). On a side note, I see that Hurricane Irene has its eyes set on the Eastern Seaboard.  I am hoping that everyone will take caution in my home state of NJ.

Lastly, it’s amazing also to think of the depth and extent of NOAA.  With oceans covering 70% of our planet and the entire planet encompassed by a small envelope of atmosphere that we breathe, it is fair to say that the National Oceanic and Atmospheric Administration is a part of our everyday lives.  I am in the Bering Sea, one of the most remote and harsh places this planet has to offer and across the country, there are “Hurricane Hunters” flying into the eye of a hurricane that could potentially impact millions of people along the Mid Atlantic………..Both operated and run by NOAA!

May 5 – 6, 2011

My adventure with the NOAA Hurricane Hunters started bright and early in Savannah, Georgia. I met the crew in the hotel lobby before the sun had even begun to rise and we were off to the airport. The crew of the aircraft were Aircraft Commander Carl Newman, Co-Pilot Cathy Martin, Flight Engineer Dewie Floyd, Crew Chief Wes Crouch, Flight Director Barry Damiano, Program Manager Jim McFadden, and Technicians Bill Olney and Todd Richards. Once we got to the airport the crew immediately got to work preparing our aircraft, a Lockheed WP-3D Orion, for departure.

NOAA has two WP-3D's. We would be flying on Kermit today. The other plane is named Miss Piggy and is currently in Fairbanks, AK.

While they were working, Barry gave me a safety briefing and showed me where I would sit, how to put on my seat belt, and what to do in case of an emergency. During our preparations the rest of the passengers arrived. Besides myself, several people from the National Hurricane Center, and Rick Knabb from the Weather Channel would be accompanying us on our flight to Fort Lauderdale, Florida.

Once the crew had gone through their pre-flight checklists, we all gathered for a pre-brief. The Commander went over the flight plan and the flight director briefed us on the weather that we would encounter on our flight.

Everything looked good and we were ready to take off. I was so excited for takeoff. I have flown in airplanes before, but for this flight I would get to see what happens in the cockpit. I got to sit in the chief scientist’s seat and it was pretty amazing. I put on my headset so that I could hear the pilots communicate with each other and the tower.

I'm ready to fly!

It was amazing how many buttons and switches there were and how the pilots knew what each one did. When it was our turn to take off the propellers got louder and we raced down the runway until we lifted off the ground.

A pilot's job is not easy. This is just some of the buttons and switches that they have to memorize.

Heading down the runway and getting ready to takeoff.

My favorite part was when we went through the clouds. It was surreal to watch them get closer and closer and then we cut through them effortlessly.

Flying through the clouds on our way to Fort Lauderdale

Our flight to Fort Lauderdale was just over an hour long and we flew along the Atlantic coastline. It was cloudy for the majority of the flight, so we didn’t see too much, but the clouds did open up as we flew over Cape Canaveral and we saw the NASA Vehicle Assembly Building and the shuttle landing strip.

Watching the landing from the cockpit was also pretty cool. The plane lined up with the landing strip and we got closer and closer until we gently touched down.

As we pulled up to the tarmac we could see everyone waiting for us. Several emergency response professionals, local National Weather Service employees, and volunteers would be helping out with the Hurricane Awareness Tour today. Together we would educate school groups, the media, and the public on hurricanes, how they are studied, and what to do in the event of a hurricane.

Our morning started out with over 500 students from 13 schools. My job was to talk to the students about the instruments on the outside of the plane while they waited for their turn to tour the inside of the plane. The students were a lot of fun and they had some really good questions and observations about what they saw on the outside of the plane.

I got to teach the students about the outside of the plane before they went inside.

The students liked the stickers on the outside of the plane showing the hurricanes that the plane had flown through and the countries that it had visited.

Are those torpedoes? No, they are cloud physics probes that image individual cloud particles by using lasers (much cooler).

What is attached to the belly of the plane? It's a C-Band lower fuselage radar

In the afternoon we opened up the tours to the public. A long line formed and we slowly made sure that everyone got to see the inside of the plane. There were people of all ages and they were all very excited to see the plane and learn about hurricanes. I helped the meteorologists from the National Weather Service and the National Hurricane Center answer questions from the people waiting in line. I’m definitely not a hurricane expert, but after listening to the meteorologists all day I was beginning to feel like one.

It was very rewarding for the crew to give tours of the plane to war veterans.

After everyone had seen the plane, the crew began to prepare the aircraft for the trip home. The crew had been to four different cities over the past week on the Hurricane Awareness Tour and they were ready to go home and see their families and get some much-needed rest.

Two of the crew members were even from my home state of Michigan.

The co-pilot, Cathy Martin, and I. It was an inspiration for many of the students to see a woman hurricane hunter pilot.

For the flight home I got to sit in the navigator’s seat. It wasn’t as exciting as sitting in the cockpit, but it was cool to be able to see our course and watch our changes in altitude. The flight home was pretty amazing because we flew below the clouds at 4,000ft. I had never seen the Everglades before and it was incredible to see them that closely. It took us about an hour to get to MacDill Air Force base in Tampa, FL where NOAA’s Aircraft Operations Center is located.

I got to sit in the navigator's seat for the flight home and we didn't even get lost.

When we landed, we unloaded our gear and put the plane to bed in the hanger. I really liked the hanger because there were several NOAA planes that are used for a variety of different observations and projects.

All tucked in and ready for a good night's sleep.

It was a very long day and when I finally made it to my hotel that night, I collapsed. It was an awesome day and I was so appreciative of the commander and crew of the hurricane hunter for welcoming me onto their aircraft and teaching me about hurricanes and about what they do.

Thank you for a great day Commander Carl!
