Abstract

Global atmospheric warming and rising ocean temperatures can contribute to the acceleration of glacier melting of glaciers and influence the generation and physical characteristics of sediment flows in bays and fjords of the Antarctic Peninsula. During the First Scientific Expedition of Colombia to the Antarctic, carried out between January and February 2015, hydrographic variables (temperature, salinity, pressure and turbidity) were measured in the water column, from very close to the main glacier front towards the offshore, on 5 bays off the Danco Coast, Western Antarctic Peninsula. Glaciomarine sediment plumes from the tidewater glacier were identified in all bays; However, with variable spatial extensions as well as in the concentration of sediments, those of the central zone of the Danco coast being the most extensive and concentrated. Compared with previous years, this study recorded higher concentrations of particles on average. The greater flow of glaciomarine sediments could be associated with greater glacial melt, among other possible factors.
