Annual variation of phytoplankton at the Marian Cove, King George Island, Antarctica,2010

Abstract

To investigate changing aspects of community structure in coastal of the Antarctica, the physical factors of seawater and the phytoplankton biomass were motored at a certain point of Marian cove in Maxwell Bay. The average annual temperature was -0.6 ℃ and the annual average salinity was 33.6 psu. The annual average of overall phytoplankton biomass (Chl concentration) was 2.35 ㎍ L⁻¹. The average annual biomass of micro- phytoplankton(>20 ㎛) was 1.31 ㎍ L⁻¹ and the average annual biomass of microscopic phytoplankton was 1.03 ㎍ L⁻¹ and micro-phytoplankton accounted for 55.7% of the total biomass. The percentage of micro-phytoplankton was highest in March and microscopic phytoplankton was highest in September. To investigate changing aspects of coastal phytoplankton affected from the fact-paced changes of west Antarctic more clearly, quantitative analysis at the species level is required.
