Distribution of organic‐walled dinoflagellate cysts in surface sediments from transects across the Polar Front offshore southeast Greenland
Abstract The Polar Front along the southeast Greenland Margin denotes the contrasting hydrographic properties of the polar and Atlantic water masses on either side. The remains of planktonic organisms in underlying sediments are expected to reflect these contrasts. To test this, we quantitatively an...
