End Of the Rope : Disentangling a Humpback Whale

It is not every day you get to save the life a whale. In fact, it may not be more than once in a lifetime. However, I can say with certainty, that if you are able to successfully save a whale from entanglement it is the best feeling in the world. You will feel like life just cannot get much better!

On September 16th, 2018, the 35-foot landing craft, Silver Spoon, cruised through the flat waters of Chatam Strait about 30 miles south of Juneau, Alaska. The bluebird day was abnormally sunny for autumn in Southeast Alaska. On board, Captain Billy Mills was taking Kurt Pesch, Kathy Pesch, Kassie Pesch-Johnson and myself up the coast looking for wildlife. We passed False Bay on the east side of Chichagof Island and were near when Wukuklook River when we spotted a whale on the surface.

Marine Mammal Entanglement, Humpback Whale, Alaska
We spotted a whale on the surface. At first we thought the whale was sleeping, but we soon discovered it was towing a rope and buoys.

Ordinarily a whale on the surface is just a sleeping whale. In a typical encounter they wake up, swim a bit, and may eventually take a dive. However, this whale displayed some peculiar behavior by keeping its nose above the water. As we got closer we could see it was pulling a set of buoys behind it and those buoys were keeping it from diving. We watched the whale from a distance to determine the extent of entanglement. The whale never dove and was making distressed chirping sounds with its blowhole. Armed with this information Billy radioed the U.S. Coast Guard in Juneau to report the entangled whale. They collected information on the whales condition and informed NOAA, and informed us they not have any vessels in the region to reach us soon. The whale was moving quickly so the likelihood of NOAA resighting and disentangling the whale was low. Billy made the call to go about helping the whale as we could.

Marine Mammal Entanglement, Humpback Whale, Alaska
The entangled whale had the buoy line through its mouth with a hundred feet or so of line dragging on the left side and about 40 feet of line attached to the buoys. The buoys were keeping the whale from diving.

Before I start into the rest of this tale I need to put out a disclaimer. Humpback Whales and ALL marine mammals deserve your respect. You need to respect all rules regarding minimum distances from whales and we only made the decision to approach this whale after knowing that professionals were not available to help in this situation.  We felt the likelihood of the whale dying were high if we did not at least try to fix the situation.

We approached the whale slowly and encountered the loose green buoy line (the end not attached to the buoys) behind the whale about 100 feet. Using a boat hook we picked up the end and then began to pull the line into the boat. We pulled in much of the line before the whale panicked and took off. I was able to sever the line before the whale stripped it back out of the boat. Not many people can say they’ve had a whale on the line! The whale dove briefly but came back up a few hundred yards way to continue its pattern of swimming with its nose above the water. This just proved to us that the whale could not function without removing the buoys.

The whale was moving quickly, perhaps 12 knots, but we slowly came up behind it for a second approach. With boat-hook in hand our goal was to snag the buoys and complete the disentanglement. Soon I had the buoys in hand and we began to draw more line into the boat. We were fortunate! The loose end of the line began to slide through the whales mouth essentially “flossing” it. This allowed us to remove much of the line.

After pulling much of the line through the whale’s mouth something truly incredible happened. The whale stopped in the water, opened its mouth, and slid backwards into the ocean. It was almost as though it knew we were trying to save it! After sliding backwards into the water the whale began to move and pull the line. More slid through its mouth before finally catching. I severed the line and the whale gave a half breach, a flip of its fluke, and then we did not see it again. Although some of the line was left on the whale it was able to dive and stay down!! We felt confident the rest of the line would eventually get removed. We had done it!!!!

One of the puzzling things was why this whale was unable to stay down. Although the four crab pot boys attached it were very buoyant, it did not seem like enough to keep the whale on the surface of the ocean. The whale was medium-sized and pretty young. My theory is that the whale acted much like a horse would to the pressure of a bridle and reigns. The upward pressure of the buoys may have kept the whale on the surface. I do not have any proof that, just a theory.

After doing some research I discovered that crab pots like the one this whale entangled in are the most commonly reported. I know I will be doing my part by being as responsible as I can with my sets. Do not use floating line as was used on this crab pot set.

There are times when doing nothing can be better for the animal than doing something. It is likely in this case that the whale would have become more entangled in the long rope and would have injured itself or been unable to swim. I am proud of us all for giving this whale a far better chance for survival!

If you find a in injured, stranded, or entangled marine animal, please report it through NOAA. You can find their number for any region by visiting their website.

Sea Life and Glaciers : Seward, Alaska

There are many “Alaskas”. The large state is renowned for its dry, cold interior and also for its coastal regions. The coast itself varies from tundra to temperate rainforest and is full of a birds and marine mammals. In the Kenai Penninsula, large tide water glaciers add icebergs to the water which are used by pupping harbor seal mothers for rest. The region is known for its rising peaks which jut from the ocean as snow-capped mountains.

On the sunny, late June day, that we departed Seward harbor the sun shone on islands and mountains around us. In every direction, gulls and black-legged kittiwakes wheeled and dove over the open ocean.Our 9-hour tour through Major Marine Tours to the Northwestern Glacier and Chiswell Islands had just begun. Once in the open water past the Kenai Peninsula your feet are floating above the largest stretch of open ocean in the world – stretching thousands of miles to Antarctica. Kassie and I had birds on the brain and our small 30 passenger ship (in comparison to some of the 200 passenger ships) was perfect for the trip we were hoping to have. The waters of the Kenai Peninsula is home to many sea (also called pelagic) birds. These birds are remarkable in that the majority of them only come to land to nest, all other times- including the brutally cold winters- are spent at sea on the water. The bodies of many pelagic birds are so tuned to sea-life that they often look awkward on the land. However, their graceful, powerful ability to swim and catch fish makes up for their awkwardness.

I’ll just spoil the conclusion, by saying we had an incredible day on the water! This video highlights some of the power of calving glaciers, the beauty of sea-birds and the behaviors of marine mammals.

Birds of the Chiswell Islands

The vertical cliffs Chiswell Islands are perfect for nesting sea birds. Horned Puffins and Tufted Puffins burrow into the cracks to escape predating gulls. Parents are mated for life and separate during the winter, however find each other for every breeding season. Each of the puffin species found around the Kenai coast have extraordinary features. Horned puffins have a dark check-mark patch through through their eye which makes them look as though they have applied makeup to preform at a circus. Part of this check-mark is a horned protrusion comes off each eye like a fancy eyelash. Tufted puffins, the largest of the three puffin species, have large golden ‘eyebrows’ which waggle back and forth when they turn their head. Puffins are recognized by their large bills which they use to catch fish. Both of the pacific puffin species only have orange and cream colored bills, where the Atlantic Puffin’s bill includes blue and red. Puffins can dive up 200 feet beneath the ocean’s surface and they can hold their breath for a minute or two. However Puffins typically only need to stay under for 20 to 30 seconds at a time to catch the small fish that compose their diet.

Pelagic birds are often found in large breeding colonies located on islands. For this reason they are referred to as ‘colonial nesting birds.’ These islands provide refuge from land-based predators and the large numbers of birds act as sentries, mobbing any intruder which gets too close. Our Captain informed us that once they had spotted a Black Bear on an island that was a mile from shore. It feed on bird eggs for a couple weeks then swam back to shore. It was a very rare occurrence but it is easy to see how one large predator can decimate the nesting success rates on the island.

Our bird list added many ‘lifers’ to our life-lists (along with a couple we had already seen) and many photographs to my hard drive. Our list for the day was comprised of Bald Eagles, Rhinoceros Auklets, Horned Puffins, Tufted Puffins, Parakeet Auklets, Pigeon Guillemonts, Common Murre, Pelagic Cormorant, Double-crested  Cormorant, Marbled Murrelet, Black-legged Kittiwake, Mew Gull, Glaucous-winged Gull, and a possible Ancient Murrelet.

 Mammals of the Chiswell Islands

There several species of whales and porpoises in the rich waters of the many estuaries of the Kenai. Sea Otters feed on clams, urchins, and other invertebrates that tend to feed on kelp. The Sea Otter is a keystone species that helps to protect the kelp beds providing shelter for a plethora of other sea creatures. Doll Porpoises, Humpback Whales, Fin Whales and Orcas cruise through the waters. The Fin Whales were a rare occurrence for the tour, our guides said they maybe see a Fin Whale 20 times a summer. Our tour saw a very rare pod of at least 6 Fin Whales surfacing together, which meant they were most likely rounding up bait fish instead of filter-feeding. On the rocks, 1 ton Stellar Sea Lion males watch over their harem of females, and the ice flows at glacier heads provide rest for harbor seal mothers and their pups. We saw several pods of Doll Porpoises throughout the day, on the way back to the harbor we had a small pod that decided to race in our wake.

One of the highlights of the trip was observing a “lunge feeding” humpback whale with her calf. Lunge feeding is when a whale dives far below a school of food (krill or small fish). Then, rushing to the surface with their mouth open the burst through to the open air swallowing anything in their mouth!

Glaciers of the Kenai

The Harding Ice Field is the largest ice field in the United States and is the source of dozens of glaciers. Some of the glaciers reach all the way down to the ocean and are classified as ‘tide water’ glaciers. These glaciers are constantly being eroded by the oceans daily movements and some of the glaciers have receded miles since the 1800’s when the Russians were exploring the coasts. The receding glaciers open up habitat for mammals and birds. The Northwestern Glacier that we sat in front of stretched for a half mile across the blue fjord, but you would never guess its size by just looking at it!

One can get a true sense of power of the tide-water glaciers by watching them ‘calf’. From time-to-time sheets of ice would break away from the exposed glacier face and cascade into the ocean. Even though our boat was positioned 1/4 of a mile away the rush of sound from the huge chunks of ice sounded like a jet engine rumbling in the not to far-off distance.

If you’ve made it this far I’d like to put in a quick pitch (unsolicited) for the Major Marine Tour company. Their boat the Viewfinder was piloted by a great captain and the tour guide on board was great with kids and had all the answers. The small size of the boat and number of passengers was perfect for us. They were more than happy to concentrate on birds when we told them what we were after. It was an extraordinary day.

Secondly, I would like to put in another unsolicited pitch for the Alaska Sea Life Center in Seward. Their exhibits are truly top-notch, and the chance to experience the pelagic sea-birds up close was wonderful. On top of that, proceeds go towards outreach and science. I am not normally a “zoo type” person, but everything I saw there impressed me to no end!

Thanks for checking in!
