Whale Channel, British Columbia , 5/6/2023, National Geographic Sea Lion
National Geographic Sea Lion
Well, as the name suggests, we found some whales today. Whale Channel is sheltered from the open Pacific Ocean by numerous small islands and channels, making up a patchwork of waterways primed for life. Fjords are glacially-carved valleys flooded by seawater during the retreat of their respective glaciers. Fjords have only one way in and out. In some areas, fjords become crisscrossed, creating channels that have multiple entries and exits. This allows huge amounts of water to surge in and out of the system, lending itself to high marine productivity.
We saw the results today. Dozens of humpback whales were seen during our transit, with two of particular interest. Over the course of an hour, we watched as two seemingly unattached humpbacks used their massive flukes to slash the water like a fan two to three times before lunging through the concentrated school of krill that developed in response to the frothy chaos. The strategy seemed to work because the same behavior was used by more humpbacks later in the day.
Not only were humpbacks in the mix, but we also saw two fin whales, a much more unlikely sighting on the British Columbia coastline. To top it off, just before recap, a few sleek, black dorsal fins broke the surface to reveal killer whales. Most likely northern residents, this very small group (at least four) was busy swimming back and forth, likely chasing the salmon that are staging for their return upstream later this year.
Cetaceans were the order of the day with fin and humpbacks representing the whales and Orcinus orca representing the dolphins. May the wildlife continue!

This morning found us where the Pacific Ocean meets Cross Sound and Icy Strait, the Inian Islands. Named by William Healey Dall, one of Alaska's earliest scientific explorers, in 1879, the Inians are a mecca for wildlife. The powerful tidal currents flowing in and out daily create a tremendous upwelling of nutrient-rich water. This area is where fishing boats from the various ports in the northern portion of the Inside Passage enter and exit. It was a glorious day with calm seas, which allowed us to cruise around the various islands in our Zodiacs drinking in the fantastic scenery and looking for wildlife. Unmissable were the Steller (or northern) sea lions, the largest member of the “eared seals,” first described in 1742 by Georg Wilhelm Steller, the German surgeon and naturalist on the Bering expedition. We saw many of them on “bachelor haul-outs,” rocks where single males of all ages bask, posture and feed on numerous species of fish. Sea otters with pups are just about the cutest animals on the planet! As members of the weasel or mustelid family, southern sea otters are the smallest marine mammal. Like other members of this family, they have very thick fur. In fact, at 850,000 to 1 million hairs per square inch, sea otters have the thickest fur of any mammal. Without blubber to protect them from chilly ocean waters, sea otters rely on their thick fur.
The “crown jewel of the Park Service” is a fitting title for Glacier Bay National Park. With blue skies above and Marjorie Glacier in front of us, we started our day of exploration. Brown bears roamed the shorelines, mountain goats did convincing imitations of laundry piles. A group of Steller sea lions seemed to take exception to our attentions towards the goats on Gloomy Knob and photo-bombed them. Onward to Geike Inlet where a sleepy brown bear reclined in a snowbank, and five wolves traipsed up a snow slope, and a moose reclined down the inlet in the same style as our prior bear. Onward to South Marble Island with the boisterous and odiferous Steller sea lions draped about the shoreline rocks. Staccato squawks of kittiwakes and other gulls filled the air as a pair of bald eagles sporadically took flight, upsetting the avian residents of the island. A stroll around the park headquarters at Bartlett Cove amongst bird song and golden light put the finishing touch on our day in a gem of a national park.
Our day began with an on board stretch class on the sun deck led by our wellness specialist. Not only is this a great way to prepare for the day's activities, but participants have a pretty good chance of seeing wildlife amongst the beautiful Alaskan backdrop. Fresh smoothies were offered at the end as a reward! Later that morning, our team embarked on an extraordinary Zodiac expedition to the breathtaking Inian Islands, situated off the coast of Alaska. Nestled within the Gulf of Alaska, these pristine islands are home to a diverse array of wildlife. Under the captivating sunshine, we encountered an awe-inspiring ecosystem teeming with sea lions, otters, humpback whales, and eagles. Join us as we delve into the fascinating world of these magnificent creatures and unveil the wonders that May brings to this marine wonderland. Sea lions, Rulers of the Rocky Shores: As we approached the rocky shores of the Inian Islands, we were greeted by a boisterous chorus of barks and growls emanating from the colony of Steller sea lions. These massive creatures can grow up to 11 feet in length and weigh over a ton, and they rule over the rocky outcrops with their majestic presence. We marveled at their agility as they effortlessly navigated the treacherous terrain, leaping from one rock to another. Males, with their impressive manes and formidable size, asserted their dominance, while playful pups engaged in spirited frolicking nearby. These intelligent and social animals reminded us of the intricate dynamics of their society, where hierarchy and vocalizations play a significant role. Otters, Mischievous Guardians of Kelp Forests: In the tranquil kelp forests surrounding the Inian Islands, we had the privilege of observing the enchanting behavior of sea otters. These charismatic creatures, renowned for their playful antics, floated on their backs and used rocks as makeshift anvils to crack open their favorite meal—abalone and sea urchins. Their thick fur, composed of up to one million hairs per square inch, kept them warm in the chilly waters. We were enthralled by their dexterity as they groomed their fur meticulously, almost as if performing an underwater ballet. It was truly a delight to witness these mischievous guardians of the kelp forests; their presence is vital to maintaining the delicate balance of the ecosystem. Humpback whales, Singers of the Sea: Our journey took a momentous turn as we encountered the gentle giants of the deep—humpback whales. May marks their arrival in the waters surrounding the Inian Islands after they migrate from their tropical breeding grounds. These magnificent creatures, measuring up to 50 feet long and weighing up to 40 tons, graced us with their majestic presence. With each exhalation, towering spouts of mist pierced the air, announcing their presence in a grand spectacle. We were enthralled by their acrobatic displays as they breached and slapped their tails against the water, seeming to celebrate their arrival in these abundant feeding grounds. The air was filled with the haunting melodies of their songs, a testament to their extraordinary communication skills. It was a truly humbling experience to witness these gentle giants in their natural habitat. Eagles, Lords of the Skies: As we explored the rugged cliffs and towering trees of the Inian Islands, we couldn't help but notice the commanding presence of bald eagles. With their iconic white heads and piercing eyes, these majestic raptors soared effortlessly through the skies, embodying the spirit of freedom and power. Their sharp talons and keen eyesight enabled them to spot fish swimming near the surface of the water. We watched in awe as these formidable hunters swooped down with incredible precision to snatch fish from the water's surface. The presence of these magnificent birds added a touch of regality to the already awe-inspiring landscape.
