Science Log

Before I left Scammon Bay, all of our students K-12 signed and decorated a Styrofoam cup. I carefully packed these cups and brought them onboard the Norseman II in order to send them to the bottom of the Bay with the ROV Kraken on one of its nighttime dives. So, last night was the night for the deepest dive! I stuffed paper towels into each cup and dropped them into a mesh bag. The ROV crew tied the bag of cups to the frame and down, down, down they went!

About 6:30 the next morning, I hurriedly went up to check on our cups. Wow! All the cups were miniatures! The water pressure had compressed the air from the Styrofoam as the ROV had descended and the cups shrank!

Now all the students of Scammon Bay have a souvenir from the bottom of Glacier Bay! What a neat object lesson these little cups will be for all the kids at school. I hope it will be something they’ll never forget.

In addition to my excitement about my student’s cups, the scientists were excited about the samples brought up from the dive. A big Red Tree Coral sample was lying on deck. By its name you would think the coral is red. But it’s not. It’s kind of pinkish orange sherbet colored. It does look like a tree, though. The bottom of it looks like a young tree trunk. And it has rings like tree rings! According to Chief Scientist Rhian Waller, unlike tree growth rings, the rings aren’t indicative of yearly growth, but of growth due to abundance of food and living conditions.

Today, we steamed back toward Bartlett Cove. Bartlett Cove is the headquarters for the Glacier Bay National Park Rangers and the little town nearby is Gustavus. Gustavus has a population of 350 and the school has about 70 students. When we arrived in port, a sea otter greeted us, just hanging out. Eating while he floated on his back. He was noisily, crunching and smacking. Sea otters typically eat urchins, clams, and mussels. At one point he crawled out onto the dock to sun himself.

While in port, we had “open-ship” tours for the community of Gustavus. Scientists and ship’s crew took groups of ten through the Norseman II showing equipment, samples and answered questions. We were thrilled that about 65 people, including children with parents and grandparents, turned out and enjoyed learning about scientific research conducted in their Bay!

I rode into the little town of Gustavus with Ranger Sarah to drop Scientist Bob Stone off at the airstrip. Sarah drove us around on a tour. Gustavus is a beautiful little town with a gorgeous view of the Fairweather Mountain Range. One super cool thing that you can see in the Gustavus Public Library: an Orca skeleton hanging from the ceiling! Orca whales stay in Glacier Bay year round.

After the ship tours, the Park Rangers took us on a short walking tour around the visitor’s center. The National Park Service is partnering with the local Tlingit tribes in making this location once again a gathering place for them. They are building totem poles and a tribal meetinghouse designed by the tribal elders.

We learned that the Tlingit tribe lived in the area before the Bay was formed. It wasn’t yet a Bay because it was still covered in a giant glacier. The Tlingit still have songs and stories that tell of the glacier moving as fast as a dog running! So they hurriedly got in their canoes and fled to safety. As the glacier surged it destroyed their homes and scoured the land. They re-settled into places like nearby Hoonah, a native village across the way.

Before we left Bartlett Cove, everyone gathered with Qanuk and I on the dock sign for a photo with the winning banner designed by Scammon Bay 4th graders!

Now we’re all back on the ship and heading out to open waters. The glassy waters of the Bay are gone and it’s looking like a rough ride.

I already feel a bit queasy……

Personal Log

Since the ship’s work is ongoing 24-7, it seems that one day runs into the next because someone is always up and at work. And someone is always asleep in the stateroom. I’m amazed at how smoothly things work. Everyone pulls together to help each other and get the work done. If you think about it, there are LOTS of things going on. For example, the meals must be prepared and dishes washed. The science work must be done—scuba diving and processing during the day and ROV diving at night. The ship must be piloted and navigation is critical at all times. General housekeeping is always going on. It’s all an impressive operation and I’m happy to be here and hopefully a productive part of the team!

Happy Birthday to Cheryl!

This is Cheryl!

Unbeknownst to Cheryl, Chief Scientist Rhian Waller, even though she was very busy preparing for the cruise, brought balloons, streamers, candles, and noisemakers to celebrate Cheryl’s birthday today.

The ship’s chef is secretly making her a cake. The celebration is slated for tonight at dinner. Shhhhh……

This morning, Chief Scientist Rhian Waller announced that we are steaming toward the end of the west arm of Glacier Bay to Johns Hopkins Glacier. This is a place where cruise ships take tourists in the Fall. But the Park Service has it closed during the Spring and Summertime because it’s a harbor seal nursery. The nightshift workers are trying to catch a few winks of sleep before we get there. No one wants to miss it. We are hoping for clear skies. Johns Hopkins Glacier is one of the few glaciers that is advancing instead of receding. As it advances, it is joining the Gilliman Glacier.

It’s 10:30 am and we’ve arrived sooner than I expected. Johns Hopkins Glacier is really something to see! So massive. Once again everyone is out on deck taking pictures and oohing and aahing.

The glacier has shades of blue and white with streaks of brown and gray. It has a covering of white snow that looks like cake icing. The glassy water is a blue-green color with a multitude of icebergs floating in it. Bob Stone uses a term we all like—“bergy bits”—meaning small pieces of floating ice. He even brought some “bergy bits” onto the ship for us to add to our water or soft drinks. So refreshing!

While on deck taking pictures we hoped to see the glacier calve and fall into the sea. It sounds like thunder. We waited and we waited and finally a couple of small ones happened. Also, a couple of snow avalanches slid off the mountains into the water leaving dirty brown streaks along the slopes.

Our scuba divers went down for another exploratory look and came up with a first! They found Primnoa pacifica in the West Arm! This is the first Primnoa pacifica ever found here. They described it as spindly and small in comparison to the others found in the East Arm.

The scuba divers continue their search for Red Tree Coral.

The significance of this Red Tree Coral being in the shallow water is that it has been considered a deep-water coral. There are two broad categories of coral: warm-water coral and cold-water coral. Generally, warm-water coral live in shallow, tropical waters. Cold-water coral live in deep water. The emergence of cold-water corals like Primnoa pacifica in the shallow waters of Glacier Bay has caused scientists to re-evaluate their understanding and descriptions of these organisms.

The third and last scuba dive for today was described as “mud, mud, and more mud”. A bit of a disappointment but they did bring up an interesting little critter.

This sea peach is a tan color here in the wet lab, but according to Bob, in its natural habitat it has a bright cherry red color.

Birthday party for Cheryl!

Well, it’s finally suppertime! That means “Birthday Party Time!” The ship’s chef, Harry served up a delicious meal of salmon, barbeque chicken, steamed kale, baked summer squash, scalloped potatoes and a big salad. For dessert, he prepared a layered chocolate cake with freshly made whipped cream and strawberries. Everyone sang “Happy Birthday” to Cheryl.

After she blew out the candles we went out on the deck and ate cake with new friends in the view of majestic mountains and glaciers.

A birthday to remember, I’ll say.

Now it’s back to work and the ROV crew is getting ready to deploy Kraken 2 for another night of exploration!

Personal Log

Today has been a day of anticipation and inspiring wonder. I’ve tried to stay out on deck watching the glacier. Hoping for calving and avalanches. It’s really neat to me that no one else is here. We haven’t seen anyone else except four Park Service employees who boated out to meet us today. I found out that there are over 1,000 glaciers in Glacier Bay National Park! Some of them aren’t even named. I enjoyed watching a couple of bald eagles sitting on icebergs. And the absolute coolest thing has been the discovery of Primnoa pacifica in the West Arm of Glacier! I could feel the excitement in the air!

It’s so thrilling to be a part of this scientific exploration and to learn from these world-class researchers!

My Lab Work large
My lab work: a tray of Primnoa pacifica samples labeled and preserved for reproductive studies

Today, the coral processing continued for genetic, isotope, and reproductive studies, which has been very intensive for the last two days and nights. During the daylight hours, the divers collected samples of the coral in shallow water (30 meters) and during the nighttime hours ROV Kraken 2 collected the coral samples from the deep (210 meters).

Chief Scientist Rhian Waller tells me that the coral processing work will slow down for a few days because we are leaving the known sampling sites and heading into the unknown. Unknown territory for Primnoa pacifica, that is.

According to Rhian, the most important task today has been the completion of this collection series for Primnoa pacifica (Red Tree Coral). With both shallow and deep samples, geneticist Cheryl Morrison will be able to map the spreading patterns of the Red Tree Coral in Glacier Bay!

There were a total of four exploratory dives today. The divers are having a blast! They wore GoPro cameras on their helmets and used “underwater scooters” to go faster and farther during their dive time constraints. A scooter is a handheld engine with a propeller that pulls a diver behind it. Bob Stone describes it to be like sledding underwater!

In addition to the Red Tree Coral, they’ve brought up some really interesting specimens, which include sea stars, nudibranchs, shrimps-one very pregnant shrimp loaded with eggs, a polychaete worm, a bioluminescent ctenophore, sea pens, and sponges.

On one of the dive outings, they took Qanuk and sat him on an iceberg! It was a really beautiful blue iceberg. Blue icebergs have ice crystals that are more tightly packed therefore they reflect more blue light wavelengths than other colors of wavelengths.

This evening, scientists are once again gathered around the monitor to see what the ROV Kraken 2 will discover. So far, we’ve seen crabs, goose barnacles feeding on plankton floating in the water, anemones, poacher sturgeon, sea cucumbers and moon snails. Sounds like a yummy salad, doesn’t it?

Personal Log

Today everyone settled into their jobs and it was a smooth operation. The scientists and crew are still brimming with excitement about the possibilities for this voyage. I was glad to get the intensive coral processing completed. Though it’s very important work, it’s tedious and repetitive. One very nice bi-product of working with the coral is the scent. Red Tree Coral smell like cucumbers! Also, we get to see all the other curious types of samples brought aboard such as glowing ctenophores and jumping shrimp! I’m getting to see so many things I’ve never seen before and it’s wonderful to have experts help explain everything. They are genuinely interested in sharing knowledge with me in hopes that I will take it back to the classroom for my students in Scammon Bay. Scammon Bay kids have become important to these world-class scientists! Another cool thing about these scientists, even though they are experts in their fields, they are also eager students for learning something new. Enthusiastic lifelong learners— what an inspiration!

All in all, it’s been a good day in Glacier Bay.

Science Log

Happy First Day of Spring!

Last night the remotely operated vehicle (ROV) Kraken2 dove and collected many samples of Primnoa pacifica (Red Tree Coral). The science crew excitedly gathered around the monitor to see what Kraken2 was “seeing”-lots of rocks, a few fish, a few shrimp, a few crabs, a couple of sponges, an octopus and lots of beautiful Red Tree Coral attached to the rock faces.

The ROV Kraken2 is run by a crew of engineers from the University of Connecticut and makes nighttime dives to deeper depths between 130 and 170 meters.

Today we busily processed the coral for genetics, isotopes, and reproduction studies to be conducted later by a series of scientists in various labs scattered across several states.

For the genetic samples, polyps (one individual) of coral are smashed onto special paper folders that contain a preservative. For the isotope samples, polyps are put into tiny vials then frozen. For the reproductive samples, an intact piece of coral is placed in a 15-milliliter tube and then submerged into formalin preservative. Later the formalin will be poured out and ethanol will be poured into the tubes. Preparing the reproductive samples is my job!

Three divers went down four different times collecting samples, all near White Thunder Ridge and Riggs Glacier in the eastern arm of Glacier Bay.

Riggs Glacier is showing numerous crevasses, which are usually snow-covered at this time of year. A crevasse is a big crack on the topside of the glacier.

As the evening approached, the ship steamed to the northernmost end of the East Arm where Muir Glacier was waiting to greet us. Muir Glacier is named for Naturalist John Muir who explored in Glacier Bay during the late 1800’s.

Muir Glacier was once a tidewater glacier at the water’s edge but in the last ten years has melted and receded back up into the valley.

The sky was clear and the snow-capped mountains and waterfalls were beautifully reflected in the still waters of the Bay. A gibbous moon rose over the mountain peaks just as the Sun was setting.

Personal Log

Today I learned how to process the samples for genetics, isotopes, and reproduction. My responsibility was to put a small branch of coral into a tube of Formalin. Labeling the tubes with place, depth, and species is important so the scientists as they begin working in the laboratory weeks later will know the source of the coral sample.

As we worked, Chief Scientist Rhian Waller came into the wet lab asking if anyone wanted to ride in the skiff, my heart started beating faster! I didn’t want to be pushy so I kept quiet. Then she said, “Mary would you like to go out on the skiff?” “Yes! I loved to go!” was my reply. I donned the Mustang suit, hardhat, and rubber boots. I grabbed Qanuk and went outside to load into the little RHIB, which had been lowered from the deck on to the water beside the ship’s hull. When everyone was ready, we motored closer to White Thunder Ridge. The diver’s entered the water and explored the region at about 70 feet deep. Meanwhile we waited for them and kept a watch on their bubbles rising to the surface. We used binoculars and viewed five fluffy mountain goats moving along the Ridge! It was cool to see the mountain goats but they were creating a “falling rocks” hazard for those of us down below. Our boat driver decided to move the RHIB away from the Ridge in order to avoid the rocks tumbling down into the water.

Later in the day, when the Norseman II got closer to Muir Glacier, almost everyone was on deck getting that perfect photo of the mountains reflected in the mirror-like waters of Glacier Bay. It was a remarkable scene!

So at the end a good day, I am feeling very thankful to be a witness to the scientific work in an effort to better understand this pristine wilderness.
