Horizontal and Vertical Distribution of Antarctic Phytoplankton at the Weddell Sea Ice Edge Zone
Program year: 1988/1989 Digitized from print original stored in HDR The scope of this research is to quantify phytoplankton cell numbers at the Antarctic ice edge in horizontal and vertical dimensions during austral winter. Identification is to the species level where possible. Other methods of esti...
