This year, a team of NOAA scientists completed a re-sight trip by boat from the eastern Aleutian Islands to the Gulf of Alaska. The purpose of a re-sight trip was to survey Steller sea lion rookeries and haulouts for previously marked animals, similar to Steller Watch citizen scientists who look for marked animals in remote camera images. This year, after many years of working at the Marine Mammal Laboratory, looking through more than 200,000 remote camera images, I finally had the opportunity to go into the field and see Steller sea lions in person, for the first time.

On July 12, I met the other three women who would compose our team at the airport, on our way to Dutch Harbor via Anchorage. I had heard many horror stories of canceled flights and stranded researchers trying to make their way to Dutch Harbor, so I braced myself for the worst case scenario when we arrived to Anchorage. My first surprise was that the only gate for passengers travelling to Dutch Harbor had no TSA, and upon checking in, every passenger was weighed with their carry-ons before getting on the plane. As we waited for our flight, we watched the crew load luggage onto the plane, wondering if ours would make it. Lucky enough, it was smooth sailing and we arrived in Dutch Harbor on our first attempt, luggage and all, just in time for dinner. We stayed the night in the only hotel in Dutch Harbor. The next morning, we got up bright and early to get the gear ready and hauled over to the M/V Pŭk-ŭk, our research vessel and home for the next two weeks.

LGR_DSC01812.jpg

Once aboard the Pŭk-ŭk, we wasted no time and set off for our first site. I took in the first views of the beautiful green cliffs and incredible wildlife—as well as the onset of nausea (sea sickness!)—as we entered the Bering Sea. The weather was too bad for us to survey that day, so it wasn’t until the second day that I saw my first Steller sea lion. The first skiff survey was at Tanginak, a lower priority site home to a mere 12 sea lions. Our team donned large mustang suits for warmth and flotation, climbed down into the skiff from the Pŭk-ŭk and observed the sea lions while the skiff driver navigated our boat back-and-forth in front of the site. We used stabilizing binoculars to look for marked animals and conducted counts while we slowly moved closer to the site in a zig-zag fashion, so as not to disturb the sea lions. Once we were sure we had a thorough look at each sea lion, we returned to the Pŭk-ŭk.

DSC01743.JPG

DSC01639It was on our second day of surveying when I was the first person to spot a marked animal, an exciting and personal feat. After that, finding them became much easier. On day three, we visited seven sites but only needed to get in the skiff for a closer look at three of the sites. Cape Morgan (Akutan Island) was the first large rookery I had visited, with over 1,000 sea lions. Larger sites, such as this one, took a couple hours to survey, and despite the cold and rain, I enjoyed every moment. My favorite site was Billings Head (Akun Island), a large rookery tucked into a cove at the base of a massive bluff. The water was so clear you could see to the bottom. Some curious sea lions would come and investigate the skiff, while we rapidly called out the brands of the many marked animals we were seeing to the data recorder. The remainder of the two weeks continued the same fashion, doing multiple surveys some days, and other days, remaining on the boat and not surveying because of bad weather or because we were travelling between sites.

DSC01591.JPGBy the end of the two weeks, we had surveyed 29 sites. All but five had sea lions, and four we surveyed multiple times. Multiple trips to larger sites like Cape Morgan or Billings Head gave us chances to see new sea lions that were out foraging during our previous visit. In total, we observed 98 different marked individuals, many of which we saw more than once. One male was even present at Billings Head and then the next day we saw him at Cape Sarichef (Unimak Island), which are 50 kilometers apart! We also saw six dead sea lions (unknown causes) and, sadly, two entangled animals (packing bands). In addition to Steller sea lions, we saw sea otters, harbor seals, northern fur seals, a pod of humpback whales feeding, and even heard the calls of one very lost California sea lion. While we could have had better weather—we were unable to work due to poor weather a total of 5 days—it was still a productive trip.

The data we collected will help us better understand Steller sea lion survival, movement, and reproductive success of this endangered population. The information we collected, in addition to the data collected from Steller Watch, will help us understand the potential causes for decline of this fragile population.


I began working at the Marine Mammal laboratory for an internship in 2014 analyzing Steller sea lion remote camera images. I completed my senior thesis project on sea lion pup birth timing for my Aquatic and Fisheries Sciences degree at the University of Washington, where I also earned a degree in Biology. After graduating, I was contracted to continue my work at the Marine Mammal Laboratory analyzing remote camera images. I am currently a research biologist with the University of Washington’s Joint Institute for the Study of the Atmosphere and Ocean (JISAO) at the Marine Mammal Laboratory where I analyze high-definition videos from camera tags placed on Northern fur seals to study feeding rates, prey availability, and foraging success. 

And we’re back!

The Steller Watch team is back from our 2018 summer field season

The Steller Watch team is back from a busy field season and we’re hard at work processing and analyzing data that we have collected over the summer. We had a couple of research cruises and an aerial survey to study Steller sea lions in Alaska this past summer.

mmlfieldwork.jpg

There was also field work to study northern fur seals! Over the next few months me and some of my colleagues will be sharing more in-depth stories about these trips and results. But, for now, I’ll just give you a brief summary of what we were able to accomplish to study Steller sea lions.

Western Aleutian Island Research Cruise:

20180623_attu_cape-wrangell_0002.jpg

During our annual research cruise on board the U.S. Fish and Wildlife Service R/V Tiglax  we focused our efforts in the western Aleutian Islands, boarding and disembarking from Adak, Alaska. Weather was quite a challenge this year but we did quite well despite the fog and wind.

Pup work

We were able to visit the highest priority sea lions sites to look for marked animals, conduct counts, and do drone surveys. We were also able to access all of our remote cameras to collect over 330,000 images! There were three sites where we went to shore to work up pups in order to help assess pup condition in this area of concern. We handled almost 150 pups–phew! They were heavy…

NOAA Twin Otter Aerial Survey:

asslap_2018_sitessurveyed.png

During the time we were on the R/V Tiglax in the western Aleutian Islands, our aerial survey team, including NOAA’s Aircraft Operations Center pilots and mechanic were surveying the area from the Delarof Islands to the east, along the Aleutian Islands. During our cruise, we had challenging weather and the fog and wind caused a lot of problems for our aerial survey team, as well! They didn’t get as many days of flights completed as is possible during a ‘good’ weather survey year, but despite the spotting nature of surveying, they were able to cover a lot of ground!

ben_9691.jpg

They even got to check out Bogoslof Island, which is an island that had been erupting pretty consistently in the previous year! Check out all of those fur seals, sea lions, and marine birds.

Lynn_3812.JPG

Eastern Aleutian Islands & Gulf of Alaska Resight trip:

Like the other two Steller sea lion projects, we encountered some difficult weather during our resight trip, as well. It didn’t keep us down! This was the first trip I’ve been on where we had a scientific crew that was all women! We were able to accomplish a lot of work in the Eastern Aleutian Islands and spotted many marked sea lions. Once we moved into the Gulf of Alaska, currents and winds slowed us down a lot which meant we had to focus our efforts on getting back to Homer in time to get home.

Steller Sea Lion Field Camps (Cancelled):

Unfortunately, this year the Marine Mammal Laboratory were unable to run the two annual Steller sea lion field camps. This is the first year since early 2000 when the field camps have not been conducted.

What’s next?

We returned with over 330,000 images and guess what? We still need your help to get through these images on Steller Watch. While we were away, you all did a great job completing 55% of the classifications in the Presence of Marked Animals workflow! We have a new set of images that are now live in or Presence or Absence workflow. Thank you Steller Watch team for your continued help and support!

Well, Steller Watch team, it’s that time of year again! We are gearing up to head out for our summer field season to Alaska to study Steller sea lions. While we are away, we will not be present on our Project Blog or the Talk Forum. Our current workflow will still be live while we are away! We are hoping to be almost complete with this current set of images very soon since we plan on coming back in the fall with a whole new set of images!

mmlfieldwork.jpg

We have several Steller sea lion trips happening this summer, very similar to last year: a research cruise to the western Aleutian Islands, a traditional aerial survey, and a resight cruise to the eastern Aleutian Islands and Gulf of Alaska. Unfortunately, this year we are not able to do our field camps. This will be the first time since our field camp effort began a couple decades ago that we will be unable to do field camps (except for in 2006 when field camps were on hold due to a law suit). Other science groups from the Alaska Fisheries Science Center are heading out this summer for field work, as well.

Western Aleutian Island Research Cruise:

This year’s cruise is very similar to last year. We will be on board the U.S. Fish and Wildlife Service’s R/V Tiglax for about two weeks surveying between Attu and Adak Islands. During this trip we will be conducting count surveys by boat, land, and air with our drone. We will also be looking for marked animals at all the sites we visit and visit those sites with remote cameras to collect more images for Steller Watch! We will be doing some work with pups to collect data to help figure out more about pup health in the Aleutian Islands. Finally, there will be a couple whale biologists on board with us to help look for whales in the area, including killer whales.

NOAA Twin Otter Aerial Survey:

Since 2006, NOAA’s Aircraft Operations Center has operated a NOAA Twin Otter for the aerial survey that will go from the Delarof Islands to the western Gulf of Alaska. This means they mostly operate out of Adak Island and Dutch Harbor. We even hope they’ll be able to check out Bogoslof Island, a volcano that erupted for over a year and has more than doubled in size. Will we see Steller sea lions, northern fur seals, and sea birds?

Eastern Aleutian Islands & Gulf of Alaska Resight trip:

We are not able to do field camps this year but luckily we are able to do a resight trip to look for animals that were marked on Ugamak Island, just last year. During this trip, we will just be visiting sites to look for those newly marked one year olds and marked adults beginning around Dutch Harbor and ending in Homer, AK.

A HUGE thank you to those of you who have contributed to Steller Watch! We’ll be back in the fall with many, many more images to share!

Getting away from it all . . .

Returning from two months away at a remote field camp

I was one of the seven researchers who lived on a remote Alaskan island to study Steller sea lions during the 2017 summer breeding season. These field camps are important for studying behavior and vital rates (like survival and birth rates) of Steller sea lions across their range – much like what you’re doing on Steller Watch! People always ask me what it’s like to spend two months on a remote island in the Aleutians. I can honestly say that it’s some of the best months of my year!

I have just returned from my fifth summer at a Steller sea lion field camp and was stationed on Marmot Island for the first time! Picture a cabin in the middle of moss-covered woods, situated a couple hundred feet back from the beach, next to a fresh water lagoon. Can’t get more picturesque than that! Now imagine you get to wake up to birds chirping every morning and while you sip your coffee on the deck, fox kits (baby foxes) wrestle a few yards away and deer graze a little way off. Doesn’t sound too bad, huh? Those days make up for the times when the weather refuses to cooperate (heavy rain or strong wind) and fog obscures even the lagoon from view.

IMG_3953.jpg

I was stationed at this cabin with one other field camper. Each day, we completed a four-hour shift at a Steller sea lion rookery (breeding site). A two-mile uphill hike is required to get to this site which, depending on the day, can be amazing. However, care must be taken to avoid devils club, a spiky monstrosity, and cow parsnip (also known as pushki), which contains a photosensitive chemical – it reacts with the sun and can cause blistering or skin discoloration. Machetes are sometimes required, especially in the beginning of the season, to clear the path and we take extra precautions to avoid coming into contact with pushki “juice”.

Once at the site, we sit about 500 feet above the sea lions, with harnesses and climbing ropes clipped into an anchor system to ensure our safety. Our location allows us to observe the sea lions without disturbing them. Using binoculars and spotting scopes, we observe and record behavior of marked sea lions, as well as any other marine mammals in the area (e.g., killer whales), disturbance events (e.g., caused by rock slides), or sightings of Steller sea lions entangled in fishing gear and other marine debris.

Most days, these shifts fly by since watching Steller sea lion behavior never gets old to me. There’s always cute pups suckling or playing together; juveniles bouncing around the rookery, sometimes sneaking milk from females who are unaware; females giving birth; and males fighting to keep their territories. Having done this project for many years, I get to see the same animals every day and sometimes across multiple years. This allows me to get to know these individuals and makes collecting data exciting. What always amazes me about these animals is their hardiness and their ability to survive in harsh sub-arctic conditions!

IMG_3896.jpg

One unique thing that I observed this summer was a female nursing two juveniles! It’s rare for sea lions to have two dependents, though having a juvenile and a new pup is more common on Marmot Island than Ugamak Island. However, I have never seen a female nursing two juveniles. That’s a lot of milk that she has to supply each of them. That means that this female must be very healthy, which is a great sign!

IMG_3891.jpgAt the end of the day, if it’s cold or raining, we light a fire in the wood stove to dry our field clothes and gear and get cozy inside our cabin. Our evening entertainment consists of watching the fox kits play or suckle mom, observing eagles or kingfishers perched around the lagoon, or maybe even just curling up with a good book by the fire. It’s nice to get away from the rush of normal life for a while. I count myself lucky that I get to study Steller sea lions from such an amazing location and I hope to continue this work for many years in the future!

The Steller sea lion field season is over and everyone has returned to the office, hard at work processing and analyzing data, and writing up reports. If you’d like to read all about our different trips and scientific goals for each trip, check out our previous Steller Watch blog.

I was fortunate to participate on the research cruise and the re-sight trip. Despite some challenging weather, we were very successful and productive! We also saw a lot of amazing things along the way. Though I had a great time during my four weeks away, I have to admit I’m pretty excited that I won’t have to share tight living quarters with several other people until next year!

Be sure to “Follow” our blog to see more posts over the coming weeks from biologists, field campers and volunteers who participated in this summer’s Steller sea lion field season. And, great news: you can now use the new Zooniverse app to classify images.

During the research cruise on the M/V Tiĝlâx, two big goals we had were to look for previously marked animals (like those you all are looking for on Steller Watch) and to visit a select group of sites to count sea lions. These sites were missed during last year’s Aleutian Islands abundance survey. This means, I was able to fly six sites with our new co-pilot!

We also visited three sites and marked almost 300 pups for our long-term life history study: Gillon Point (Agattu Island, “~” symbol), Hasgox Point (Ulak Island, “>” symbol), and Ugamak Island (“A” letter). Handling and working with these large sea lion pups (weighing 70-110 lbs) is a lot of work but an amazing experience. In the first image (below, left picture) you can see a pup that fell asleep while hanging in the net during weighing!

After weighing, the two pup handlers (middle picture) carefully move the pup to the veterinarian’s station where she applied gas anesthesia until the pup fell asleep. During this time, we collect samples and apply the mark (you can read more about this process here). These pups were then released to the recovery area where we kept a watchful eye to insure they were fully awake and mobile. In the right picture, you can see small square patch of fur has been shaved off. This fur sample is used to measure contaminants, such as mercury.

UlakCameras_fadely

Maintenance of and downloading images from our remote cameras were other important goals during the cruise: we collected 245,972 images from 17 of the 20 sea lion remote cameras. For the last two years we haven’t been able to access two of the cameras at Cape Wrangell (Attu Island) due to large waves at the landing site. If the cameras are still working well, they should still be snapping away and capturing images. The third camera was on Cape Sabak (Agattu Island). We were able to get to it but there were no images captured due to some technical difficulties. We did end up putting a new camera on Cape St. Stephens (Kiska Island) for a total of 21 cameras!

AI_Tiglax_Campbell-5.jpg

During one of our visits to Hasgox Point we had some unexpected visitors that delayed our work for a day. Two killer whales showed up at the rookery and were swimming around for hours! While we didn’t see any direct sea lion kills, we knew these were transient, or Bigg’s killer whales (“mammal eaters”). It seemed as though they were almost practicing hunting maneuvers. The most interesting thing to see was how the sub-adult and adult males reacted; these males would jump right in the water and swim around, very close to the killer whales! If you’d like to learn more about killer whales in the Aleutian Islands, we have a post coming up from one of our volunteers from the cruise in a couple weeks—be sure to “Follow” our blog so you don’t miss a thing!

Bogo10_fadely.JPG

On our way east, we were fortunate that Bogoslof Island, a volcanic island which has been erupting since December 2016, calmed down enough for us to check out (at a safe distance). The island has changed a lot since the last time we visited in 2015. It is much larger and even higher in elevation than before. Interestingly, despite the volcano continuing to erupt, there were thousands of sea birds and hundreds of northern fur seals and Steller sea lions on shore! Looks pretty warm and steamy.

Gearing up for the field season

We heading off to Alaska and we will be back in August!

The office has been humming with energy lately. It’s that time of year, the field season is just around the corner. Spring and summer are busy times at the Alaska Fisheries Science Center. This is the time of year when the Center conducts the majority of its field work. Weather in Alaska over the winter isn’t conducive to getting work done, though summer weather offers no guarantees, either!

While we’re away, we will be putting the Steller watch project on hold starting June 20th. Since we won’t have internet while we are in Alaska we can’t respond on the Talk Forum but don’t worry! We’ll be back in August with many more images and stories to share with you all.

Some of the Center’s research trips this year include bottom trawl and hydro-acoustic groundfish surveys, marine mammal aerial surveys in the Arctic, harbor seal vessel surveys, Cook Inlet beluga aerial surveys, and vessel surveys to deploy passive acoustic recorders to record marine mammal sounds. Along with Steller sea lion surveys, our program will also conduct several studies on northern fur seals.

We have four Steller sea lion trips planned, similar to our efforts in 2016. And like all the field work at the Center, these trips require a lot of preparation. It is a coordinated effort to ensure we have everything we need since we will be isolated in very remote places and can’t just run to the store if we forgot something. Here’s a little background about each of our Steller sea lion trips:

Remote field campsobservation-site

One of our featured bloggers, Katie Luxa, has been working with other biologists to accomplish the large task of packing and preparing gear to be shipped up to Alaska to our remote field camps. They have also been preparing the week-long training class for the seven biological observers who will be living on two uninhabited islands (Ugamak and Marmot Islands) for almost two months. The field campers will live in rudimentary shelters with limited electricity, no internet or cell phones, and no running water. They will be perching above sea lions, going unnoticed to collect data on marked animals and sea lion behavior.

Research cruise

One of the trips I will be participating in will be our annual research cruise on board the U. S. Fish and Wildlife Service (USFWS) Research Vessel (R/V) Tiĝlax̑ (pronounced TEKH-lah; Aleut for eagle). For two weeks, 13 people from the Alaska Fisheries Science Center will call this 120 foot vessel home. Every summer, six skilled USFWS crew members operate this vessel, a vital platform, for nearshore research along the Alaska Maritime National Wildlife Refuge.

During our trip, the primary goal is to study sea lions to collect population counts, service our 20 remote cameras and download images (more images to come for our citizen scientists team members!), look for marked individuals, and mark individuals for on our ongoing research project. Along with sea lion biologists, there are two fish biologists who will dropping an underwater camera near sea lion sites to get a better idea of the available prey. There will also be two killer whale biologists on board looking for killer whales and other species of whales.

hexacopterTo prepare for this trip, I’ve been working with our other remote pilots to test out our new camera mount, called a gimbal, mounted to our hexacopter (or drone). The gimbal mount ensures that the camera will always point directly down and over the sea lions no matter how much the wind causes the hexacopter to tilt. I’m excited to see these mounts in action! We also have a new person on our team who you heard form in our last post about the NOAA Corps. LTJG Blair Delean will be heading up to Alaska with us for the first time to help with hexacopter surveys.

Aerial survey

2_Otter

Biologists (and featured bloggers) Lowell Fritz, Josh Cutler, and Katie Luxa will be heading out on the annual aerial survey. The team will meet up with NOAA Aircraft Operation Center flight team and Twin Otter aircraft in southeast Alaska. They will survey along the coastline, capturing images of sea lions hauled out on land at known sites.

The aerial survey team assembled and tested our camera mount that holds three cameras; it will be installed on the NOAA Twin Otter. Now we know it’s working fine, I’m packing up all the gear to ship to Alaska.

Re-sight trip2014_akutan_cape-morgan_resize

After the aerial survey and research cruise, Katie Luxa and I will meet up in Dutch Harbor (Unalaska Island) for our final survey. We will be on board a small boat for six days, checking out nearby sea lion sites for marked animals.

While we’re away, we will be putting the Steller watch project on hold starting June 20th. Since we won’t have internet while we are in Alaska we can’t respond on the Talk Forum but don’t worry! We’ll be back in August with many more images and stories to share with you all. Thank you all for your contributions classifying so many images before we head out. It’s been a joy to share our research with such dedicated people and we are so happy to have you as apart of our team!

Wish us calm seas, clear skies, low winds, and many sea lions!

Sea Lion Summer Camp

Living and working at remote field sites in Alaska

Have you ever wanted to get away from it all? No phone, no internet, no car, no electricity. Just you and a little cabin in the wilderness…and a few thousand noisy neighbors.

Each summer, NOAA’s Alaska Fisheries Science Center sends observers to field camps on two remote islands in Alaska: Marmot Island, near Kodiak Island in the Gulf of Alaska, and Ugamak Island, near Dutch Harbor in the eastern Aleutian Islands. Observers spend about 10 weeks on the islands where we are responsible for monitoring Steller sea lions hauled out on beaches. Every day, we scan the beaches for marked animals, count the sea lions on land, and record behavioral observations. These data provide a fine-scale look at two Steller sea lion populations and, in conjunction with other field studies and the remote images you’re helping to examine, contribute to our understanding of this species across its range.

helo-with-gear

So how do we get to a Steller sea lion field camp on an uninhabited island in Alaska? By helicopter, of course! But our journey really begins in Seattle. Field camp observers go through a week-long training in Seattle where we learn about Steller sea lion biology, data collection, and the responsibilities involved with living in a remote shelter on a small island with only 1 or 2 other people, away from it all. In many cases, this is also our first opportunity to get to know one another – communication and cooperation are vitally important when working with a team in remote location for over two months.

food-shopping

After training, we spend 3 days in the town nearest our assigned field camp (Kodiak or Dutch Harbor) to organize equipment which includes our rain gear, datasheets, cameras, etc. We also complete one of our most daunting tasks: buying 2 months’ worth of groceries. On deployment day, the helicopter transports us – along with all of our food and gear – to our temporary island homes. I also like to hum the Jurassic Park theme to myself as we land. Once we have unloaded, we get straight to work and by the end of the day, we will have set up our composting toilet hut (no indoor plumbing here!), solar panels, water filter, propane cook stove, cabin heater, and put away all of our food. It’s still light outside, but the clock reads 10:00 pm. Welcome to the land of the midnight sun!

The next day is dedicated to setting up our observation sites so we can start collecting data. Depending on the camp, the site may be just a few minutes’ walk away over wind-blown tundra dotted by wildflowers or at the end of a 2-mile hike through dewy meadows and moss-covered Sitka spruce. These are some of my favorite places on Earth. No matter how close the observation site is, though, we always make sure we’re prepared: datasheets and extra pencils, a camera with charged batteries, binoculars, a satellite phone, a VHF radio, a Personal Locator Beacon for emergencies, extra layers of clothes, bear spray (for those on Marmot Island), and plenty of water and snacks.

We use the same observation sites from year to year; these spots were selected because they allow us to safely observe sea lions without disturbing them. Our goal is to go the entire 10 weeks without the sea lions realizing we’re there. The sites range from about 350-1,000 feet above the beaches, so we use anchor systems and wear climbing harnesses each time we approach the cliff edge.observation-site As soon as we’re clipped into the anchor system, we’re ready to get comfortable and watch the hundreds of sea lions on the beach below.

Within a few days, we settle into an easy rhythm of data collection and camp life. We get to know the daily patterns of the marked animals. We witness fierce battles over territories. We watch sea lion pups learn to swim. And we live happily ever after. That is, until it’s time to decide who gets to empty the composting toilet.
