Variability on phytoplankton size structure in the western Antarctic Peninsula (1997–2006)

The temporal and spatial variability of phytoplankton size structure of waters west of the Antarctica Peninsula (WAP) was investigated between 1997 and 2006. Time series of satellite-derived (phytoplankton size structure index or γ b bp , chlorophyll a concentration or chl T, and sea-ice extent) and...

Zusammenfassung:The temporal and spatial variability of phytoplankton size structure of waters west of the Antarctica Peninsula (WAP) was investigated between 1997 and 2006. Time series of satellite-derived (phytoplankton size structure index or γ b bp , chlorophyll a concentration or chl T, and sea-ice extent) and shipboard (temperature, salinity, nutrients, and mixed-layer depth) variables were generated during spring–summer in slope, middle shelf and inshore waters and analyzed in relation to atmospheric anomalies (El Niño Southern Oscillation, ENSO, and Southern Annular Mode, SAM). The sampling design included stations north (northern, 62°S) and within (central and southern, 64–68°S) the Pal-LTER (Palmer Long Term Ecological Research) study site. It is hypothesized that contribution of ‘small’ phytoplankton (
