| We conducted a scanning electron microscopic survey of morphological variations in the calcareous nanoplankton species Emiliania huxleyi in Southern Ocean surface water samples collected along a transect from 43 to 64 degrees S and 141 to 145 degrees E during November 2001, October to February 2002/2003, 2003/2004, 2004/2005 and 2005/2006. The results were compared with historical data from a similar transect occupied in December to January 1983/1984 and January to February 1994 and 1995. While E. huxleyi was absent or extremely sparse (0.1 to 1 cells ml(-1)) south of 60 degrees S in 1983/1984 and 1994/1995, this species was consistently present at about 100 cells ml(-1) between 60 and 65 degrees S during 2002 to 2006. The extended geographic range and/or... |
