Week in Review

Monday, April 23: The ice is back so we have resumed our ice observation. Every two hours we haul ourselves up to the Bridge and write down our observations in a form. It averages about 7 times a day, and Robyn and I split up the observations so we have equal numbers. We are contributing ?

Weather was really icky. The morning helicopter observations were canceled because of poor visibility and wind. The wind has calmed down a bit, but the fog is still present. It will make for difficult observations in some areas. The rest of the research team is working steadily in the labs. They are all looking forward to the sampling of the ice algae for tomorrow. Robyn and I are trying to prepare for the webinar for Thursday. The scientists who will be on the show have been super helpful in providing us with materials for the webinar.

Tuesday, April 24: Scientists on ice. We hit very thick ice last night. The scientists are ready to go out for an ice sample. The ship just tucked up, into the ice. It let down a metal ramp, and down we went. All of the scientists were very excited to get off the boat. They have been stuck in a lab since the cruise started.

Most of the scientists are doing experiments associated or needing seawater. The stop on the ice was the first for all of them, to drill ice cores, collect ice and melt it down. When they return to the ship, they test it to see what secrets it may tell. The visit to the ice had almost a party-like atmosphere. Remember the reason they were collecting ice samples, was because of the puzzling results they were getting. I believe every single scientist and assistant were on the ice except the marine mammal and bird folks, who are doing a different kind of sampling. The scientists were on the ice from 8:30 am through 11 am. That is the time when oxygen release and chlorophyll is dramatically observed and measured. They will be returning to the ice in the future to continue to take the ice samples.

Seal Tagging: Oh, but my day was not over yet. I was about to get a hands-on experience in tagging ice seals. Instead of re-explaining it all here, I thought I could ask you to go into my journals and check the entry ‘Seal Tagging Adventure.’ You can get very good details and photos of the event. We got back to the ship around four pm. My tail was dragging from leaping over snow banks and falling over ice chunks. Tagging seals is a very rigorous science occupation.

Wednesday, April 25: Getting ready for the webcast. This was the last full day we had to deal with all the background of materials that needed to come to us for the webinar. Both of the scientists Alex DiRobertis, and Jeff Napp, provided us with a nice powerpoint presentation for our audience to see while we talked.

It was also time for me to start preparing for the classroom visits to St. George and St. Paul Islands. There were activities to write, brochures to track activities, and materials to hunt down. That took a lot of time for me, because I decided to take the students K-8. Robyn took the 4 high schoolers. All of my students would rotate through two different classes. In each class there were three different stations. I wanted to engage the students in some kind of active learning.

It was also time to write and reflect on the seal tagging.

I took almost 150 pictures of the seal tagging adventure. I needed to select the best for the Journal Article on tagging seals. I also needed to write an article and highlight those images in the Journal. I completed it by the end of the day, and turned it back to the Polartrec website along with the 18 pictures I selected to illustrate the activity.

Thursday, April 26 Webcast day. A zillion details to wade through. To make matters a bit more complicated, the place where we normally have our webinar was going to be used by the science team, so we had to seek out an alternative spot to broadcast.

At first we chose the chief scientists room. But the static and noises from the phone made us try yet another room. Down on the third floor to try two other rooms. Time was tight, it was 12:30 time to broadcast! So we decided to start it going in the regular spot and then move out into the hallway as the scientists meeting continued.

However, as soon as we moved, the feedback from the speakers overwhelmed us. For every word we spoke there was an echo. We were just about to hang up early when someone got the bright idea to go into my room and continue the webinar. All 7 of us picked up one piece of the telephone system and moved as one into my small stateroom.

We were good to broadcast for another 10 minutes, before the iridum phone broke connection. We tried and tried to call back. On the last try, Robyn got through. After 60 minutes of technological torture, we were done! Yahoo! And now back to the St. George presentations we were developing for the next day. I stayed up until 1:30 making pollack, krill, and phytoplankton puppets. I also needed to put all my Hawaii products out for the kids to try. Dried pineapple, mango, ginger, candy postcards, and pencils. I hoped the students would enjoy learning about my students on Maui. I checked and double checked my duffle bag to make sure I had all the materials and then some more!

Friday, April 27, 2007: The zodiac to St. George. Right after breakfast, the team of scientists and others (us teacher kine) were directed to the helo area (where the helicopter is stored) to put on our survival suits. The MS 900. Since I was going to have my students try on the suit I was wearing, I was able to keep it on, and change into my street clothes at the school.

The zodiac ride over was so much FUN! Splash, splash, kersplash, the person at the front of the bow got very wet. The rest of us hid behind him and let him take the salty spray. Once on the island, we were transported to the school via a little white bus.

THAT’S when the fun really began!

We did an icebreaking activity (person bingo) that was a real hit! Each person had a piece of paper with 20 questions. Each person had to find someone in the general meeting area who could answer that question right. Then, they put their name on the sheet. The first one with a complete blackout wins.

Then we rolled into our next activity, ‘Which creature do you identify with best?’ There were loads of people who stood by the polar bear, humpback whale, and walrus. The phytoplankton and pollack were ignored by everyone.  Hopefully by the end of the day, they might warm up to this microscopic creature and learn that it controls the entire ecosystem.

The elementary students and middle schools funneled through my stations. Of course their favorite was the station about Hawaii, mostly because of the treats I offered, perhaps? I do believe they have learned a little more about my island home and the students I teach. I hope we can continue or friendship via a blog spot I recently set up. They were incredibly respectful and curious students!

We brought the four high schoolers and some teachers and community members back o the ship with us. They were given a nice tour of the boat and supper. Back to the zodiacs they went. We waved Aloha to our new friends.

Saturday, April 28: St Paul. The other Pribilof Island. Stormy seas were forecasted. To the Coast Guard it was all about safety. To Robyn and me it was all about getting there and back. We had a presentation scheduled for the school from 11-12:30. We wanted to connect with the community.

St. Paul is larger than St. George. The helicopter was an efficient way to transport people off the boat (those who were going home) and pick up people coming to the boat (those scientists who were joining our adventure). Robyn, David Doucet (air safety manager) and I were the first flight out. Robyn and I were very excited and nervous at the same time.

Up and off we flew, 6 miles from the ship to the airport over the freezing cold Bering Sea. One minute on the ship, blink twice, we were landing safely at the airport in St. Paul. Tonia Kushin, teacher from St. Paul and I had been in contact with each other since late March. We wanted to bring her students culture to my students culture and make a meaningful connection. She took us on a tour of St. Paul, and then took us to her school. Both Robyn and I took in her tour like a sponge.

It was a wonderful time! We were set up in the library, a most fantastic place to learn. Surrounded by student made kayaks, a seal skeleton, and many antique photos from the olden time, we began our introductions.

Our education activity stations were a hit. I think the one the students enjoyed most was getting into and out of the MS 900 suit and bunny boots.

We talked to the audience about marine mammals, then broke into activity stations, then were treated to a celebration of dance. Their costumes were gorgeous!

Their dance lively!

Their song rang clear and sweet.

It brought tears to my eyes.

I went back to the Aleut classroom to see their costumes up close and was rewarded with the students coming up to me and answering all my questions. Their wonderful teacher too!

She told me that the dancing group is getting smaller and younger with each passing year. Seems many teenagers are no longer interested in learning the Aleut ways. I understood what she said. It is difficult to compete with videogames and the internet. I see some of my students in Hawaii making those same choices.

Before we knew it, it was time to go. The wind had picked up considerably and we needed to leave the school, WIKI WIKI!

We said a hurried good-bye, and left St. Paul behind. I left the island with a treasure trove of memories, and a stack of Styrofoam cups for the St. Paul students experiment “Down to the Deep.”

That kinda says it all for me.  This experience is all about science and making cultural connections. It is all one ocean, one voice, one earth.

We took the zodiac to St. George Island today, an island that is part of the Pribilof Islands, north of the Aleutian chain. Right after breakfast, the team of scientists and others (us teacher kine) were directed to the helo area (where the helicopter is stored) to put on our survival suits. The MS 900.

Science Log

So there I was just working on my journal entry when a phone call came through into the science conference room. Dr. Michael Cameron, Ice Seal Team leader, was on the line. “We are going to try to tag a seal on the ice,” he said, ”meet us in the helo hanger.” I dropped the phone and exited the conference room as fast as my rubber boots would allow. What a great opportunity this was. I was going to see what it would be like getting a tagging event together!

Imagine my surprise when Dr. Mike came thumping down the ladder from helo headquarters, “Get dressed, you’re coming with.” My heart was beating in my throat.

Me? Coming with! I MUST be dreaming!

The rest of the seal team was casually slipping on their ice gear suits and white overcoat. I wriggled into an extra large survival suit, my bunny boots, and the white lab coat, which acted as camouflage. All I needed was a red safety helmet and off we went.

I needed to gear up in a MS 900 in order to participate in the seal tagging event. I might not look fashionable, but I certainly am prepared for the unexpected. The MS 900 is a survival suit that is insulated and waterproof, just in case you fall through the ice.

We were transported to the ice via the ‘Man Basket.’ The ‘Man Basket’ is a steel cage suspended from a long cable and driven by a crane. The crane operator lifts the basket, steers it, and then lowers it down to a stable section of the ice. Once the basket has stopped moving, you slip out of the basket, and there you go.

The seal team and bear watch designee were the first group taken down to the ice. As soon as they landed, they were scrambling over the rounded pack ice berms and bumps towards the seal threesome. I knew the importance of them getting out there quickly in order to catch either of the adult spotted seals.

The seal team quickly goes to work to try and catch the spotted seals.

Before too long, the basket returned, lifted us up into the air, and down onto the frozen Bering Sea. Gavin Brady, the last of the seal team, was off like a shot. I urged him forward to do the job he was here to do. My clumsiness held him back like an anchor. I tried hard to hurdle the icy ridges and rafts, but the MS 900 worked as an efficient brake to dull my progress.

I’m OK! Just GO!

The short sprint to the seal location took my breath away. The seal team worked lightening fast to net the two adult spotted seals. They used a huge net, that looked like a huge butterfly net,  to trap them, and then transferred the animal quickly into a hoop net. My job was to watch the baby and make sure she wouldn’t separate from her mama and get lost in the open water.

I wasn’t the only one seal sitting. Dr. Mike restrains the spotted seal while seal team takes valuable data.

I wasn’t the only one seal sitting. Dr. Mike restrains the spotted seal while seal team takes valuable data.

But I wasn’t the only one seal sitting. In order to restrain it safely, one of the researchers straddles the seal, sits on it’s back, and controls its head and front flippers. Spotted seals have sharp, sharp teeth and they can telescope their neck to inflict quite a nasty bite. One researcher volunteers to act as a restrainer, which allows the scientists to collect their data quickly and effectively

The team concentrated on the two adults, one female and one male. I watched the baby. Of all the tasks that were available at the seal tag site, I think that was the best.

Taking advantage of my close but respectable distance I took many pictures of the furry bundle with very sharp teeth.

I was totally impressed with the speed and agility of the seal team. One of their major goals is to gather the data, and tag the seal as quickly and painlessly as possible. Their teamwork and communication was exemplary and allowed the mother seal to return to her offspring in a surprisingly short period of time.

Happy reunion between mother and pup.

Happy reunion between mother and pup.

Because I was preoccupied with the baby seal watch, I had missed out on what samples the scientists were collecting. Remember they are gathering data, some of it baseline for ice seals.  The tagging will produce information that is original and first of its kind. So if you were to gather information on ice seals, what kind of information would YOU collect?

The male spotted seal and I were soon to find out.

Sexing is first on the agenda. Male or female? One hole or two?

Next is tagging the seal. The seal tags are marvels of technology. They contain computer chips and batteries that will permit the researchers to discover how deep the seals dive and when, where, and how often do they haul out. Two small holes are pierced through webbing between its toes, and the tag is securely attached. As soon as the seal returns to the sea, the salt water activates the tag. It will continue satellite transmission for up to a year.

Shawn Dahle and Josh London prepare to attach the tag to the back flipper of the spotted seal.

Then the tissue from the flipper is placed in a small vial for DNA testing. Scientists can map the DNA and discover information about the different individuals and populations. Following tissue sampling, blood is taken to learn of the seal’s health. The researchers use a syringe and insert it into a special cavity (dorsal sinus) of the spotted seal, an easy target for them to tap. After the tagging event, the team will take the blood back to the boat and separate the solid red blood cells from the light colored serum. It is the serum that contains the antibodies and information.

Dr. London puts the blood into a ‘tiger tube,’ a special test tube that has a  layer of wax to separate the high density red blood cells from the serum.

This serum will be frozen, along with the tissue, for another scientist who specializes in blood work to decipher its content. Lastly, measurements are made. We didn’t have enough time to weigh the animal. The researchers use numbers recorded from tape measurements at the hip, belly, front flipper, and neck. They put the numbers in a special equation that use a special ratio to determine a good estimate of the weight of the animal.

Measuring the length and width of a seal is a quick way to get a fairly accurate measure of weight.

The seal team does a quick check and double check to make sure all the numbers have been recorded. But there is an additional sample that the male spotted seal has left for the science party.

You know poop? Doo doo? Number two?

I was told that all wildlife biologists start out as scat collectors. Scat or vomit is commonly used to figure out what, how, and how much animals eat. The seal team was very happy to delegate scat collection in a whirl bag (special sample bag) to me.

They even had a special little shovel to transfer the scat to the bag.

The trek back to the ship was more relaxed than the sprint out. We needed to wait for the helicopter to take two members of the ice algae productivity sample group back to the sampling site we were at in the early morning. We got Andy, our Bear-Watcher-Outer, to take pictures of us all. Dr. Mike and the rest of the ice seal team were incredibly happy.

So there you go. From start to finish, a whirlwind of valuable data gathering, done in an efficient and non-invasive way. Yeah, this is science.

This is science done right.

Science Log: Science on Ice

We hit very thick ice last night. That is exactly what the scientists were waiting for.  So the ship just tucked up into the ice, let down a metal ramp, and down we went.

The scientists were able to walk off the boat by way of this metal ramp. They had to grasp the handrails and walk backwards down the ramp. It was like climbing down a ladder.

Before I started this adventure onboard the Healy, we were told about the opportunity to run a deep-sea pressure experiment with our students. All that was needed was a Styrofoam object decorated with Sharpie pens. I got some Styrofoam balls and bowls, a package of Sharpies and the students went to work decorating the objects.

They were a bit difficult to pack. The goal was to get them here in one piece. The TSA at most airports did all they could to protect my fragile cargo (NOT!) When I got on the ship, I put them on my desk and waited for the opportunity.

This little mesh bag held the Styrofoam balls.

This little mesh bag held the Styrofoam balls.

It just so happened that on Saturday night, April 21, we were going to have a deep, deep, station collection. The CTD (rosette water sampling machinery) was to be dropped down to 2500 METERS. So we gathered our travel mesh bags together, stuck the Styrofoam in the bags, and went in search of the CTD operator, Scott Hiller, from Scripts Oceanography Institute. He said no problemo! He’d make sure the Styrofoam balls, bowls and cups got down there and back.

Scott Hiller from Scripts Oceanography Institute said he would make sure the balls,  bowls and cups would be taken down and up again.

Scott Hiller from Scripps Oceanography Institute said he would make sure the balls, bowls and cups would be taken down and up again.

So in the interest of science, I stayed up late, determined to see the experiment through from start to finish. The hours ticked away. 8 o’clock, 9 o’clock, 10 o’clock. The rosette sunk deeper and deeper. 11 o’clock, 12 o’clock, 1 o’clock, 1:30 it hit the bottom.

These Styrofoam objects were tucked in a mesh bag and tied to the side of the CTD rosette.

That’s 2500 METERS. So how many feet is that?

It had to sit on the bottom for 45 minutes, and then get hauled back up to the surface. 2:00, 3:00. Wow, I was up, witnessing a science experiment at 6 hours past my regular bedtime. Now this is science!

Scientists regularly stay up to do their research at all hours of the night.

When the rosette hit the surface, attached were the Styrofoam forms, but what did they look like? Your assignment is to write a hypothesis as to what you think happened to the balls and bowls that were lowered into the deep deep Bering Sea.

Stay tuned!

Science Log

I am sure that you know that there are many different scientists on board, all researching pieces of the Bering Sea ecosystem puzzle. Recently, some of the scientists started talking with each other because some of the results have not been what they expected. They asked, why is this happening and what is causing this to happen?

There were some puzzling results that couldn’t be explained from the data samples.

Their conclusion?

No dirty snow here. This ice is covered with ice algae. Ice algae is the producer of the Bering Sea.

What the heck, you might say. How come this piece of the puzzle has gone unchecked? Might I remind you that many of these scientists are doing baseline studies? They are collecting data from one or more of the factors in the ecosystem. Never been done, at this time, in this place before.

The information that is being collected is fed into a computer and displayed as a graph.

So a meeting was called. At that meeting were the researchers who were discovering that there was something missing. These researchers told the group of scientists that they believed their missing data had to do with the ice algae. That they needed access to algae samples that were not sent into shock from the collision of the icebreaker and the ice.

Scientists often have to make their own data sampling equipment. It is a mixture of science, engineering, and creativity.

Now here is the interesting part. Everyone agreed. EVERYONE agreed. This aspect of the BEST (Bering Sea Ecosystem Study) cruise had not been included in the research plans. Time to develop another protocol and possibly another piece of equipment that would permit the researchers to gather untouched pieces of the algae.

Researchers need to get samples of the water and sea algae. In order to get it, they need to pump the stuff up out of a teeny tiny hole they will punch through the ice.

So it became a true collaboration. Everyone worked together to create the protocol, make the sampler, to decide time of day to collect and for how long and for how many. The nutrient scientists worked with the zooplankton folks worked with the mud researchers worked with fish acoustics. Now there is a plan, and a protocol, and scientists who will be sampling ice algae from undisturbed areas in the ice. The plan was created in just two short days, in addition to their crazy research schedule. This group of scientists is pumped to find out the role of ice algae in the ecosystem of the Bering Sea.

This is a new ice filter that was created especially for this machine.

Stay tuned to this website as I am sure there will be more interesting data that will come out of all this.

And me?

I’ll be there 😉
