, and how it is expected to impact the circumpolar Arctic in the coming years. The project involved over-wintering the Amundsen in the Banks Island flaw lead in the Southern Beaufort Sea, the first time this has ever been done.

Motivation

The polar areas have many unique phenomena. Circulatory systems for air and water reach the surface, as do the majority of the Earth's magnetic field lines. Thick glaciers have trapped air and water from ancient times. It is easiest to observe these phenomena near the poles.

Unfortunately, the poles are expensive places to visit, because they are distant, cold and deserted; infrastructure is sparse and the terrain is rough in polar regions (often consisting of ice blocks with crevasses between them). International cooperative programs share the costs and maximize the number of coordinated scientific observations. The IPY is the most famous example of such a cooperative program.

History

The First International Polar Year was proposed by Georg Neumayer and inspired by an Austro-Hungarian naval officer, Karl Weyprecht

. They argued for a coordinated scientific approach, with observers making coordinated geophysical measurements at several locations during the same year. This would permit more views of the same phenomena, allowing more valuable interpretation of the available data, with only slightly more total money.

Seven years were required to organize the collaboration. There were 12 expeditions to the Arctic

The aforementioned countries operated 14 meteorological stations around the North Pole. Observations included meteorology, geomagnetism, auroral phenomena, ocean currents, tides, structure and motion of ice and atmospheric electricity. More than 40 meteorological observatories around the world expanded their programs of observations for this period. Data and images from the First International Polar Year have very recently been made available for browsing and download on the Web. These records of the First International Polar Year offer a rare glimpse of the circumpolar Arctic environment as it existed in the past and hold the potential to improve our understanding of historical climate variability and environmental change in the Arctic.

 lines began to persuade engineers and scientists that the electrical geophysics of the Earth needed more study. The airplane, motorized sea and land transport and new instruments made the proposals more interesting.

In 1927 a proposal came before an International Meteorological Committee. In 1928 the committee submitted a detailed report to an international conference of directors of meteorological services at Copenhagen. Part of one of the resolutions follows:

... magnetic, auroral and meteorological observations at a network of stations in the Arctic and Antarctic would materially advance present knowledge and understanding (of these phenomena) not only within polar regions but in general ... This increased knowledge will be of practical application to problems connected with terrestrial magnetism, marine and aerial navigation, wireless telegraphy and weather forecasting.


The conference suggested observing in 1932–1933, the fiftieth anniversary of the First International Polar Year.
The Second Polar Year (1932–33) program studied how much observations in the polar regions could improve weather forecasts and help transport by air and sea. Forty-four nations participated, and a vast amount of data was collected. A world data center was created under the organization that eventually came to be called the International Meteorological Organization

By most accounts, the privations of these two early operations were extreme, with the men spending less than 10 percent of their time on science, and the rest of the time devoted to survival.

Commemorative coin controversy

The Royal Canadian Mint's $20 silver coin, launched on July 18, 2007 has evoked one of the darkest moments in the history of polar exploration and rankled Canada's main Inuit organization. The coin was struck to mark the 125th anniversary of the International Polar Year scientific studies and features a "world first" metallic-blue finish meant to mimic the Arctic's icy hues.

A mint spokesman said the kayaker is simply meant to represent the indigenous people of the North and their role in Arctic exploration. However, the combination of elements recalls an infamous episode from Frobisher's 1576 voyage to Baffin Island and the tragic fate of an unnamed Inuit paddler who was lured aboard the explorer's ship, Gabriel, and kidnapped for transport back to England as proof of the expedition's success in reaching the New World. The Inuit captive, one of the first native North Americans known to have reached Europe, was put on circus-style display in England and became the subject of portraits, including one intended for Frobisher's sponsor, Queen Elizabeth I, before dying — probably of pneumonia or exposure to European disease — only weeks after arriving.
