ABOARD THE RVIB N. B. PALMER, ON THE SOUTHERN OCEAN– Within 40 nautical miles southeast of C18A iceberg, we found an area known as the Iceberg Alley: a large concentration of icebergs in western Weddell Sea, moving in a north-northeast direction following the clockwise circulation around the Weddell Sea gyre. Hundreds of icebergs... {Read More »}

ABOARD THE RVIB N. B. PALMER, ON THE SOUTHERN OCEAN– After a four day trek looking for other icebergs we might want to study, we came back to continue studying iceberg C18A... {Read More »}

ABOARD THE RVIB N. B. PALMER, ON THE SOUTHERN OCEAN-- We are all used to thinking of the ocean as blue. Sometimes greenish, if close to the coast, or brownish if a lot of sediments are delivered at a river’s mouth, but mostly it is blue; a clear blue close to coral reefs, a dark blue when seen from space or a grayish blue during a storm.

ICEBERG A43K, SOUTHERN OCEAN-- Phytoplankton need dissolved nutrients, such as silicate, phosphate, and nitrate to grow in seawater. Open waters in Antarctica are rich in those nutrients, particularly in winter when plant growth is limited… {Read More »}

ICEBERG A43K, SOUTHERN OCEAN-- Carbon sedimentation in the water, from its surface towards the ocean floor, is expected to increase around icebergs as a consequence of the chemical and physical environment conducive to plant and… {Read More »}
