Of Treacherous Rocks & Audacious Fin Whales

Soon large blows filled our view; small groups of fin whales sped by heading north all the while feeding on concentrations of krill & small fish. Group after group was seen, with many simply feeding in the general area and not heading anywhere in particular. Soon it became evident that we were not simply seeing a few random groups of fins, but a very large concentration spread out over a large area of sea just north and around the islands north of the South Shetlands. Dozens upon dozens of fin whales were feeding, diving around the ship and on the horizon in massive numbers; we must have seen well over fifty fin whales in the general area of Elephant Island, something many of the guides had never seen before.

Science of the Ross Ice Shelf

Antarctica’s Ross Ice Shelf is vast, spanning 487,000 sq. km – comparable to the size of France – with a thickness that varies from a few hundred meters near the sea to over 1,200 meters away from the floating edge. The edge along the Ross Sea forms a towering ice wall, rising up to 50 meters above the water, with most of the ice submerged below the waterline.

Polar bear encounter in Spitsbergen

I watch the sea ice from the bridge of a ship in one of the fjords of Spitsbergen, an archipelago north of Norway. I observe a perfectly adapted animal moving on the ice, the results of hundreds of thousands of years of ecological fine-tuning. Snowshoe-sized paws distribute weight, fur handles the cold and sunlight to perfection, and an incredible sense of smell samples this monochromatic realm.

Everything you need to know about Antarctic icebergs

The ice in Antarctica might seem static, but it is constantly moving. Pieces of ice are continuously breaking off from ice shelves, glaciers, or other icebergs. They float freely along with the Antarctic currents, with about 90 percent of their mass below the surface of the water. This fact is actually what gave rise to the nowadays popular phrase “the tip of the iceberg”. Regardless, the sighting of the first iceberg is always a moment to celebrate in any and all Antarctic expeditions. So that you may appropriately ready yourself for that joyous moment, in this article you will find everything you need to know about Antarctic icebergs.

The first race to the South Pole in 50 years

Before the South Pole could be reached, the question was what exactly lay at the southern ends of Earth. The concept of Terra Australis Incognita, an unknown continent, was first introduced by Aristotle, who reasoned that a southern landmass must exist to ‘balance’ the known lands in the northern hemisphere.
