Earlier this summer, NOAA scientists partnered with NOAA’s Aircraft Operations Center to conduct our annual aerial survey of Steller sea lions in Alaska. You can check out this post to read more about our aerial surveys.

Our trip began in Anchorage on June 19, where my co-workers and I met the pilots, mechanic, and – most importantly – the Twin Otter airplane that would be our office for the next three and a half weeks. The first order of business was to install our survey equipment: an array of 3 digital cameras mounted in the belly of the plane and a computer that controls the mount system.

The next task was to plan the flight to our first destination. Despite our ability to cover a lot of ground in the Twin Otter, Steller sea lion sites are spread out over more than 2,500 miles of coastline and weather conditions aren’t always favorable enough to fly safely and capture high-quality images. For these reasons, we split sites into two survey areas: Southeast Alaska and the Gulf of Alaska are surveyed in odd-numbered years and the Aleutian Islands are surveyed in even-numbered years. This year, an Aleutian Island survey year, flights would be based out of Dutch Harbor (Unalaska Island) and Adak Island.

Dutch Harbor is approximately 800 miles southwest of Anchorage; it is the #1 commercial fishing port in the United States and was featured in the TV show “Deadliest Catch”. Adak is another 440 miles west of Dutch Harbor, and is the site of a US naval air facility that closed in 1997. At its peak, there were up to 5,000 troops and their families living in Adak – they even had a McDonald’s! Our area of highest priority was around Adak and so we hoped to start the survey on a high note and visit those sites first. Unfortunately, the weather forecast didn’t look great, so we headed to Dutch Harbor instead.

Once we settled in Dutch Harbor, it was time to start planning survey flights. We use an app called ForeFlight to upload a list of GPS locations for known Steller sea lion sites and draw a route from point to point; the route can then be shared with the pilots, who use the same app in the plane. Depending on how close the sites are to one another and how many passes are needed to photograph the sea lions, it’s possible to visit more than 30 sites in a single flight. We try to come up with a few potential flights each day, because being flexible is key to a successful survey.

And, boy, this year was all about flexibility! We had unusually poor weather, including many days with low “ceilings” (height of the cloud layer) or gusting winds that made it impossible for us to fly. And when we were in the air, we often spent our survey flights “hunting and pecking” for sites that weren’t covered by fog. Despite our weather difficulties, though, we were still able to survey over 130 sites and take over 13,000 photos!

There were also some true highlights on this year’s survey. As Katie mentioned in an earlier post, we surveyed Bogoslof Island, which was completely transformed by a series of volcanic eruptions starting in December 2016. Compared to our aerial survey in 2016, the island had more than tripled in size and was still steaming! Bogoslof is one of the few places in Alaska where both Steller sea lions and northern fur seals breed, and it was amazing to see them there again, after such dramatic changes to the landscape.

Through the fall and winter, we’ll continue the important task of counting sea lions in this year’s images – and keep our fingers crossed for fair weather in 2019!

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:

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.

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!

Understanding the role of killer whales in the Aleutian Islands

As I peer through the binoculars, a jet-black, triangular dorsal fin slowly arcs over the ocean’s glassy horizon. There is no mistaking it… we found killer whales!

NOAA Fisheries. Permit No. 20465

For centuries killer whales have captured the human imagination. Although arguably one of the most recognizable species, there is a lot we still do not know about them… but we are learning! NOAA Fisheries’ Cetacean Assessment and Ecology Program has been studying killer whales in the Aleutian Islands of Alaska since 2001. As researchers, our goal is to better understand the abundance (how many whales there are), distribution (where the whales are), social structure, and feeding behavior of killer whales in the Central and Western Aleutian Islands. The information we learn about these populations can help us understand the role of killer whales within this fragile ecosystem. We are particularly interested in how, or if, Bigg’s (“mammal-eating”) killer whale predation or resident (“fish-eating”) prey competition may be impacting Steller sea lion recovery in the Western Aleutian Islands.

Transient killer whale predation on marine mammals in the Aleutian Islands has rarely been observed. However, on this year’s cruise we happened upon a predation event in-progress at Hasgox Point on Ulak Island.

During this year’s Steller sea lion cruise, killer whale biologist, Dr. Paul Wade, and I conducted cetacean (whale, dolphin, and porpoise) surveys from the highest point of our research vessel, the flying bridge. We spent hours scanning the horizon with our binoculars as our ship traveled from one Steller sea lion site to the next. When we sighted whales or porpoises we noted the species, group size, and their GPS location. This year we saw many cetacean species on our voyage including sperm whales, fin whales, humpback whales, Dall’s porpoise, beaked whales, and others. Surveys give us information about whale population abundance and distribution within the Aleutian Islands.

dorsal fin

When we encountered killer whales, we suspended our survey in order to collect photographs of the killer whale’s dorsal fins and adjacent saddle patch pigmentation. We are able to make an initial determination of ecotype (“fish-eating” resident or “mammal-eating” Bigg’s) in the field based on physical characteristics of the dorsal fin and saddle patch, group size, and behavior. However, photographs allow us to later confirm the ecotype designation and even identify individual killer whales from their natural markings. If conditions permitted, we launched a small vessel for closer approaches to collect tissue biopsies or deploy satellite tags.

Campbell_photographs.jpg

Transient killer whale predation on marine mammals in the Aleutian Islands has rarely been observed. However, on this year’s cruise we happened upon a predation event in-progress at Hasgox Point on Ulak Island. We observed two transient killer whales methodically “working” the sea lion rookery. The killer whales closely approached sea lion groups on the shore and in the water.

Blog-2

These killer whales may seem menacing, but Steller sea lions are not defenseless! Steller sea lions are large, agile in the water, and have big teeth that could harm killer whales. Even though many sea lions were in the water, the killer whales were not successful in making a kill and eventually moved on. The next morning we observed another group of four Bigg’s killer whales at Ulak Island. This group was more active, they hunted further away from the rookery, and displayed exciting behaviors like tail slaps, spy hops, and even porpoising.

This year we successfully deployed two satellite tags on Bigg’s killer whales. Satellite tags give us information about where the whales travel and how deep they dive, unlocking the mysteries of their daily activities. Previous satellite data from Bigg’s killer whales in the Western Aleutians has revealed distinct foraging patterns. The tagged Bigg’s killer whales made shallow dives around Steller sea lion rookeries in the early mornings and repetitive deep dives (to almost 400m!) in the evenings. This data has revealed that Bigg’s killer whales in the Central and Western Aleutians forage on both marine mammals and squid!

NOAA Fisheries. Permit No. 20465

We look forward to analyzing the data we have collected this field season (including photographs, remote camera images, satellite tag data, and survey data) and discovering more about whales in the Aleutian Islands of Alaska.

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!
