Notes

Everybody knows the story of the Titanic and of the tragic accident that cost hundreds of lives. Digging into the details of this fatal event we can trace the most likely origin of the iceberg that sank this ship to a particular glacier in West Greenland. The Jakobshavn Glacier is a spectacular fast-flowing glacier fed from the Greenland Ice Cap that produces some of the most impressive icebergs in the Arctic. Currents in Baffin Bay move some of these blocks of ice south and out into the North Atlantic where they sometime reach major shipping lanes before melting away.

Notes

Whaling is an ancient human activity that has had a great influence on the marine environment with effects ranging from the reduction of several species to the brink of extinction to modifications in the ecosystem. By the 19th century Europeans had managed to reduce the numbers of right whales in their coastal waters to such low numbers that this activity practically ceased on the Old Continent. The Norwegians were instrumental to the industrialization of whaling and the extension of this activity to the high seas and to the southern ocean in the 20th century. As a consequence of inefficient management regimes several species of large whales have risked extinction and are slowly recovering after drastic conservation measures implemented in the late 1980's. But whaling is still practiced in several areas and not necessarily for commercial purposes. Management regimes have been set in place for the large majority of whale populations (The International Whaling Commission and here), but threats to conservation are widespread and difficult to eliminate.

Notes

Tourists in polar areas typically look for pristine, untouched landscapes and wildlife encounters. The exploration feeling is what draws people to these high latitudes. Paradoxically, with the recent increase in the number of tourists, this feeling of having reached a pristine area is enhanced by the intense activities of two organizations: AECO in the North and IAATO in the South. Independently of each other, both organizations promote safe and environmentally responsible travel to polar areas by enforcing a precautionary “leave no trace” policy. Incidentally, the philosophy of traceless travel is also wittingly expounded in a popular book about human necessities while in the middle of nature.
