ABSTRACT: This
study investigated the dispersal pattern of suspended sediment in the areas
near the Stenhouse and Ajax glaciers, Visca Anchorage, Martel Inlet, King
George Island, Antarctica. This study was conducted using visible band
processing of Quickbird high-resolution spatial images obtained in October
2006. The methodology was also based on the collection and interpretation of
data obtained from water samples collected in Admiralty Bay in December 2004.
The digital processing of satellite images was performed using a classification
method based on the reflectance characteristics of water. The classified images
improved visual identification of the dispersion pattern of suspended sediments
in the study area. These data were related to the interpretation of analyses
conducted on suspended particulate matter (SPM) in the water. The sediment
dispersal pattern observed may be associated with glacial erosion processes,
their input of meltwater from the front of the glaciers into the study area,
detritus flow processes and glaciomarine circulation in the region.
