The island, which had detached itself from the ice shelf on Ellesmore Island in the Canadian
arctic archipelago, was used as a laboratory for seismic studies of the
Arctic Ocean floor, as well as charting currents, pollution,
winds and ice structure.
Moreover, the
ocean (which has been responsible for absorbing as much as 80 % of anthropogenic emissions) can become saturated, or as temperatures rise in the temperate regions or
winds increase in
arctic regions and stir up carbon dioxide from below, act as an emitter.
Canadian Ice Service, 4.7, Multiple Methods As with CIS contributions in June 2009, 2010, and 2011, the 2012 forecast was derived using a combination of three methods: 1) a qualitative heuristic method based on observed end - of - winter
arctic ice thicknesses and extents, as well as an examination of Surface Air Temperature (SAT), Sea Level Pressure (SLP) and vector
wind anomaly patterns and trends; 2) an experimental Optimal Filtering Based (OFB) Model, which uses an optimal linear data filter to extrapolate NSIDC's September
Arctic Ice Extent time series into the future; and 3) an experimental Multiple Linear Regression (MLR) prediction system that tests
ocean, atmosphere and sea ice predictors.
Polar bears,
arctic summer sea ice, regional droughts and floods, coral bleaching, hurricanes, alpine glaciers, malaria, etc., all depend not on GATA but on a huge number of regional variables including temperature, humidity, cloud cover, precipitation, and direction and magnitude of
wind and the state of the
ocean.
There are variations in
wind pattern,
ocean currents and
arctic melting.
When the
oceans are warm and the
arctic is open, the fierce
arctic wind picks up huge amounts of moisture and delivers it on land and water around the northern hemisphere.
