Once Frozen in Ice, Now Frozen in Time: Artifacts of an Arctic Voyage

Posted in Nuggets from the Archives on September 23, 2016 by Lansing Moore

Sarah Dutton is a project coordinator in the William and Lynda Steere Herbarium, where she is working on a project to digitize the Steere Herbarium’s collection of algae.

It is 1879, and for months you have been living aboard a creaking wooden steamship trapped in miles of shifting Arctic sea ice. When you venture above deck, the air is icy as you gaze across the polar landscape. Among your companions are several officers, 21 crewmen, six other European scientists of various disciplines, and a few hundred indigenous Chukchi people who live nearby.

Such was the experience of Dr. Frans Reinhold Kjellman, a botanist aboard the SS Vega during the Swedish Vega Expedition. The New York Botanical Garden’s project to digitize the algae collection in the William and Lynda Steere Herbarium has uncovered two algal specimens that Dr. Kjellman collected during this expedition, providing glimpses into a little-known but fascinating story of 19th century science and exploration.

The tale begins with Adolf Erik Nordenskiöld, a Finnish-Swedish scientist and explorer, who had led many successful Arctic expeditions by the time he proposed the Vega Expedition. This time, he planned to circumnavigate the Eurasian continent via the Arctic Ocean and the Bering Strait, or “North East Passage,” to prove that this was a viable route between Europe and the Pacific. The scientists on board the Vega were prepared to gather data about the geography, hydrography, meteorology, and natural history of the Arctic, much of which was still unexplored by Europeans at the time. Kjellman, who had accompanied Nordenskiöld on three previous voyages, was an authority on Arctic algae.

The SS Vega departed Sweden on June 22, 1878. On September 3, the ship began to encounter sea ice. The explorers continued, hugging the coast and searching for a clear way through the increasing ice. However, by the end of September, the ice thickening in front them could no longer be broken by the ship’s hull. They had reached Kolyutschin Bay, the last bay before the Bering Strait, but a belt of ice less than 7 miles wide barred their passage. In his book, The Voyage of the Vega round Asia and Europe, Nordenskiöld expresses regret over time that could have been saved along the journey. He believed that had the ship arrived at Kolyutschin Bay just a few hours earlier, they would have been able to continue. To rub salt in the wound, Nordenskiöld later learned that an American whaler had been anchored only a couple of miles away in open water on the same day the Vega was frozen in.

Lichens Hold On Along America’s Vanishing Coast

Jessica L. Allen is studying for a Ph.D. as a student in the Commodore Matthew Perry Graduate Studies Program at The New York Botanical Garden. James C. Lendemer, Ph.D., is an Assistant Curator in the Institute of Systematic Botany at The New York Botanical Garden. Lichens are their primary research interest.

The Mid-Atlantic Coastal Plain is a close neighbor to some of America’s largest cities, including New York and Philadelphia, but you’d be forgiven if you had never heard of it. This vast, low-lying region extends along the Atlantic coast from southern New Jersey through South Carolina and includes such well-known cities as Charleston and Norfolk and beaches that are enjoyed by millions of visitors every year, such as the Outer Banks of North Carolina.

From Tree to Shining Tree: The Living Network under the Forest

That old saying about not being able to see the forest for the trees turns out to be more than just a metaphor.  Standing in the middle of a forest, it’s easy to see each tree as an individual, but in reality, the trees are bound together by a living network that proves beneficial not only for the trees—which get the minerals they need to grow to great heights—but also to the network, which gets a steady supply of nutrients from the trees to keep it alive.

What is this network? That’s the mystery that award-winning science journalist Robert Krulwich sets out to answer in a recent episode of public radio’s Radiolab.

His scientific sleuthing brought him to the Thain Family Forest, the 50-acre old-growth forest at The New York Botanical Garden, where he interviewed Curator of Mycology Roy Halling, Ph.D., the Botanical Garden’s expert on all things fungal. That’s a pretty broad hint about the nature of the network, by the way.

As with all Radiolab stories, the result is an adventure in imaginative reporting and storytelling that revels in the wonders of the world around us. Or, in this case, beneath us.
