Summer changes in the vertical distribution of chlorophyll-a in Boeckella Lake (Hope Bay, Antarctica Peninsula)

Vertical distribution of phytoplanktonic chlorphyll-a in Boeckella Lake was studied during summer periods in 1992 and 1993. Two opposite sites subjected to different organic matter inputs from the adjacent penguin rockeries were periodically sampled at three depths. Chlorophyll-a concentrations vari...
