Changes in areal extent and concentration of sea ice |
|
around Antarctica may serve as sensitive indicators of |
|
global warming. A comparison study was conducted between |
|
the outputs of the three main algorithms currently in use |
|
(NASA Team, Comisco, and NORSEX) and a sea-ice model |
|
(Fine Resolution Antarctic Model). Data from the DMSP |
|
Special Sensor Microwave/Imager (SSM/I) were used as |
|
input algorithms for the time frame July, 1987 to June, |
|
1990. Large disparities are apparent when comparing the |
|
NASA algorithm with the Comisco and NORSEX algorithms. |
|
Very large differences, some higher than 30 per cent, |
|
exist in the marginal ice zones, along the coast, and in |
|
the Weddell and Ross Seas Heat fluxes through recurring |
|
polynyas were calculated to quantify further differences |
|
in the algorithms; however, no conclusive patterns were |
|
apparent. No significant change in the extent or area of |
|
the ice pack occurred from July, 1987 through June, 1990. |
