Concave Iceberg Gerlache Strait, Antarctica. “This melting iceberg probably calved from a glacier, as evidenced by bands of dark color which are sediment the glacier picked up while moving down the steep slopes of the Antarctic Peninsula. An iceberg containing sediment will absorb heat because of less reflectivity and thus will melt faster. Global warming increases the rate of glacier calving and the overall degradation of ice sheets, and also contributes to an acceleration in the rate of sea level rise.” Captions and Photo courtesy of: © Norma J.
