50-Foot Waves, the South Shetland Islands and Antarctica

(How did the two of us come to travel to Antarctica on a Russian oceanographic ship? What did we experience in the first two wild weeks of this adventure? For all the exciting photos and past installments, scroll down to earlier posts.)

Our new friend and shipmate Ruediger Loechner of Germany captured the feel of the awe-inspiring 50-foot waves, which towered over the ship. (photo by Ruediger Loechner)

"THEY'RE NOW CALLING IT A CYCLONE," One Ocean Expeditions leader Boris Wise told our group of Antarctic voyagers during dinner on the Akademik Sergey Vavilov on November 12. "The winds are over 50 knots. We're heading right for the eye of it."

Almost two weeks into our multi-stop trip from the tip of South America to Antarctica organized by the great British zoologist, wildlife photographer, writer and conservationist Mark Carwardine, Pamelia and I were getting close to the vast white continent—and also close to a massive storm, the second big blow of our voyage. We were seeing the Southern Ocean at its classic best, meaning wildest, and none of the hearty souls on board the Sergey Vavilov was complaining. We all loved the adventure. 

Let me pause to offer these words of reassurance to any of you who may be intrigued by the idea of going to Antarctica but are seasickness-prone: I am too. I learned during this voyage to preload on Bonine motion-sickness tablets, stick to my bunk as much as possible in high waves and endure jolts of electricity on the underside of my wrist from an anti-seasickness wristband that helped me immensely. I never got seasick—just a little queasy—throughout as rough a voyage as any you'll experience. So don't be deterred.

For three more days we rode turbulent seas—50-foot waves that dwarfed the 30-foot giants we'd gone through earlier—but thanks to deft navigating by our Russian captain, we avoided worse.  At last we arrived at the South Shetland Islands, on Antarctica's doorstep. We now were in a world of icebergs. Pamelia was about to set foot on her seventh continent and I on my sixth.

From every angle the towers of blue ice looked different. Much of the ice was many thousands of years old, compressed to a density and hardness that were hard to imagine.

Because of continuing waves, winds and weather, we could not go ashore for a day, but took Zodiacs through the icy world near Turret Point on King George Island in the South Shetlands. I've put together two photo galleries below, one made up of Pamelia and my shots and one of photos taken by fellow voaygers Ruediger and Eva Loechner. (Thanks again, Ruediger and Eva.)

The next morning, November 14, we awoke to a 26-degree F air temperature, 30 mph winds and a 29-degree water temperature—the perfect Antarctic feeling for our expedition to Mikkelson Point, Antarctica. This would be the day Pamelia added her seventh continent. I'll let the photos below tell the story of yet another spectacular morning of exploration.

Pamelia was ready to go as we waited to board Zodiacs for the ride ashore at Mikkelsen Harbor. She had been hoping for decades for a chance to set foot on Antarctica.

The ride to Mikkelsen aboard Nate's Zodiac was bitterly cold, choppy...and spectacular. 

A lone Weddell Seal served as our Antarctic welcoming party. Weddells (named for British sealing captain James Weddell, who first saw them in the 1820s in the Antarctic waters now known as the Weddell Sea) have the most southerly distribution of any mammal. They're found only around Antarctica, and their range extends much farther south than the tip of the Antarctic peninsula, which we had reached.

I've mentioned how quickly and dramatically the weather can change in the Antarctic. Here at Mikkelsen it never stopped changing, from blowing snow to wild clouds to sun and back. The beauty was overwhelming.

The rolling terrain at Mikkelsen is home to breeding and nesting gentoo penguins, which were clustered in several spots.

As I've written previously, the 30-inch-tall gentoos are the third-biggest species of penguin after emperors and kings. They're long-tailed penguins closely related two other species that we would unexpectedly see at Mikkelsen in the hours ahead—chinstraps and Adelies; in the course of evolution their genus broke off from those of other penguins 38 million years ago.

As mentioned, the gentoos were mating. Gentoos lay two eggs, and males and females take turn (one per day) roosting on them for 34 to 36 days. 

Gentoos are quite vocal...

...and feisty.

Some of the gentoos already had laid eggs.

I saw only one, not two, in this nest. which may have been a sign that...

...a predatory skua might have stolen one. (photo by Ruedigger Loechner)

Pamelia later painted an ink study of this battle royal. Later I'll show you the time-lapse video she created while painting it. 

This was an emergency hut—the first we'd seen on our trip through thousands of almost completely human-free miles. That is an Argentinian flag painted on the side, a reflection of the closest neighbor on the South American continent. 

These are snowy sheathbills, scavengers that we had seen near several earlier penguin and seal breeding grounds. They'll eat anything from afterbirths to feces, which perhaps explains why they seem to spend so much time cleaning and grooming themselves. 

I love this shot Pamelia took of a swooping sheathbill.

Many of the sheathbills held one leg up to retain warmth in the frigid conditions. (photo by Ruediger Loechner)

Note the stunning bill and sheath. (photo by Ruediger Loechner)

Surprise! Suddenly a lone chinstrap penguin was wandering around.

Chinstraps are slightly smaller than gentoos and loaded with personalty.

They have amazing-looking eyes.

The chinstrap and a gentoo passed each other without incident—or even acknowledgement.

And who's this? An Adelie penguin popped up next—also a loner. Adelies were first seen in 1840 by French Antarctic explorer Jules Dumont d'Urville, whose wife was named Adelie. 

Adelies stand between 18 and 28 inches tall and have particularly long tails. Their numbers have been declining on the Antarctic peninsula (perhaps because of warming conditions and melting ice), but not (yet, anyway) in Antarctica as a whole.

You may have seen the horrific news story in February 2016 that 150,000 Adelies on Cape Denison in Antarctica had starved as a result of a giant iceberg that had floated in and blocked their access to the sea. The penguins had to make a 75-mile round trip on land to get food. The consequences of melting ice in the Antarctic could be dire for the planet as a whole, but sometimes they are localized, sudden and unforeseeable.

One of our new favorite birds became the blue-eyed shag, or cormorant. Pamelia took this amazing shot.

Our friend Ruediger matched that by capturing two of the blue-eyed shags in sync. Great shot. (photo by Ruediger Loechner)

As the morning began to wind down, we could see the Sergey Vavilov in the distance waiting for us.

We hiked back past the gentoo encampments.

As always, Charles Darwin was traveling with us and was exuberant about the naturalist discoveries he was making. He had become a regular on the ship and had even begun writing his own blog. Charles continues to explore the 21st century, and relive his life and career, as part of The Naturalist's Notebook team.

Pamelia took a shot of me with some of my gentoo penguin buddies. Neither of us could fully absorb the fact that we were standing in Antarctica, the last wild continent left on Earth.

STAY TUNED FOR THE NEXT ANTARCTIC POST: We'll be taking you to Neko Harbor in Antarctica, our final stop on the continent before a voyage back to civilization through hurricane-force winds in the Drake Passage. Oh yeah. This story ain't over yet. —Craig Neff and Pamelia Markwood

Naturalist's Notebook Guest Post: Photographing the Endangered Spirit Bear

British photographer, conservationist and environmental traveler Jenny Varley shared with us some of the amazing photos she took of Kermode (KER-mode) bears, one of the world's rarest animals, on the coast of British Columbia in Canada. Kermodes (named for Francis Kermode, a Canadian zoologist who studied them) are also called spirit bears because of their white, ghostlike coloration. They're the official mammal of British Columbia. Here's Jenny's description of these extraordinary animals and her experience watching and photographing them:

Because both parents must carry the gene mutation responsible for producing a white bear, white spirit bears can give birth to black cubs, which remain black all of their lives. (photo by Jenny Varley)

Spirit bears are a subspecies of the American black bear. They are found only in the northwest coastal regions of British Columbia, predominantly in the 12,000-square-mile Great Bear Rainforest (see map below), in which they are the iconic species. On some islands in the Great Bear Rainforest, spirit bears may make up 40% of the (non-grizzly) bear population. It is estimated there may only be 300 to 400 such bears, which makes them rarer than giant pandas!

Studies have found that the white bears are more successful than black bears at hunting salmon during the day, when—from a fish-eye view—their coloration makes them less visible against the sky. (photo by Jenny Varley)

Spirit bears are not albinos and although their predominant color is white they have varying amounts of ginger in their coats. Their eyes are pigmented and they also often have pigmented snouts. The genetic basis for the white pelage has been identified as a mutation in the gene encoding the receptor for melanocortin 1, a protein involved in the regulation of pigment production in cells called melanocytes. The mutation is recessive, which means that for a spirit bear to be white it must have two copies of the variant gene—one from each parent. This also means that, depending on the genetic make-up of individual bears, a black female may give birth to white offspring, or even one black and one white, and white mothers can give birth to black cubs. 

Interestingly, a variant in the same gene in humans is present in people with red hair and freckles and who tan easily.

The Great Bear Rainforest has been described as one of the world's largest remaining tracts of unspoiled temperate rainforest. In February 2016, after a decade of negotiations, the British Columbia government announced a deal to protect 85% of the rainforest from commercial logging. On March 1, 2016, as part of the compromise, the provincial government assured timber companies that for the next 10 years they would be allowed to harvest 2.5 million cubic meters of wood each year (down from 4 million a decade ago) under "strict, ecosytem-based management rules." 

Kermode bears have been known to catch and feast on as many as 80 salmon in one session. Five species of Pacific salmon spawn in the streams of the Great Bear Rainforest. (photo by Jenny Varley)

There are a number of threats to Kermode bears. Hunting and poaching are always a danger (even though hunting white bears is banned in British Columbia, hunting black bears that carry the white gene variation is not). Falling numbers of salmon returning to the area can result in decreased survival, particularly during hibernation. 

The most significant threats are man-made; habitat loss, industry (including the continued logging), and the proposed Enbridge Northern Gateway pipeline from Alberta to Kitimat, which could result in more than 200 tankers per year traversing the narrow and pristine waterways of the Great Bear Rainforest. That project suffered a setback in November of 2015, when new Canadian prime minister Justin Trudeau imposed a moratorium on tanker traffic along British Columbia's north coast, but the Calgary-based Enbridge energy-delivery corporation says it has not given up on building the pipeline.

A male spirit bear can stand almost six feet tall and weigh 500 pounds; females, such as this one, are notably smaller and usually top out at about 300 pounds. (photo by Jenny Varley)

Many thanks to Jenny for bringing us face-to-face with these rare and remarkable bears! (photo by Jenny Varley)

On our visit to the Great Bear Rainforest, we were lucky enough to spend almost a whole day with a spirit bear and her two black cubs. One cub was very cheeky, being quite boisterous and stealing fish from Mom as she caught them. Our guide was the brilliant Marven Robinson, who, in addition to guiding, has done much to raise awareness of the dangers faced by these wonderful animals.  After a day watching the mom and cubs we saw a second mother walking along the shore.  A truly special day and such a privilege to see.  You can find more images of these bears and other wildlife on my website, www.jennymvarley.co.uk. —Jenny Varley
