Phytoplankton blooms during austral summer in the Ross Sea, Antarctica: Driving factors and trophic implications

Abstract: During the austral summer of 2014, an oceanographic cruise was conducted in the Ross Sea in the framework of the RoME (Ross Sea Mesoscale Experiment) Project. Forty-three hydrological stations were sampled within three different areas: the northern Ross Sea (RoME 1), Terra Nova Bay (RoME 2), and the southern Ross Sea (RoME 3). The ecological and photophysiological characteristics of the phytoplankton were investigated (i.e., size structure, functional groups, PSII maximum quantum efficiency, photoprotective pi… Show more

“…Normalized to an SRP detection limit of 0.17 ÎŒM, Garwood had an average stoichiometry of 6N:1P:210Si:2Fe. Recent work in the coastal waters of the Ross Sea, north of Taylor Valley found that the mean N:P:Si ratio in the surface mixed layer was observed to be 21.5:1:63 (Mangoni et al, ). Thus, these coastal streams with their enhanced P (relative to N) concentrations may be very consequential in affecting macronutrient stoichiometry during the austral summer.…”

“…To avoid this noise, a deep understanding of the factors that influence the class is needed. We, therefore, referred to previous studies [11,[33][34][35][36][37][56][57][58][59][60][61][62][63][64][65][66] on the growth/limitation of phytoplankton that determine CHL in this region and finally selected the predictors.…”

“…In the western Ross Sea including Cape Hallett, distinct phytoplankton blooms are recurrent from year to year during austral spring and summer, especially around the Terra Nova Bay [11,63]. The phytoplankton growth results from the combinations of many factors such as sea ice, temperature, wind, nutrients, and light [37,[64][65][66].…”
