Synergistic Exploitation of Hyper- and Multi-Spectral Precursor Sentinel Measurements to Determine Phytoplankton Functional Types (SynSenPFT)
Svetlana N. Losa,Mariana Altenburg Soppa,Tilman Dinter,Tilman Dinter,Aleksandra Wolanin,Robert J. W. Brewin,Annick Bricaud,Annick Bricaud,Julia Oelker,Ilka Peeken,Bernard Gentili,Bernard Gentili,Vladimir Rozanov,Astrid Bracher,Astrid Bracher +14 more
TL;DR: In this paper, the authors derived the chlorophyll a concentration (Chla) for three main phytoplankton functional types (PFTs) by combining satellite multispectral-based information, being of a high spatial and temporal resolution, with retrievals based on high resolution of PFT absorption properties derived from hyperspectral satellite measurements.
Journal ArticleDOI
Global Retrieval of Diatom Abundance Based on Phytoplankton Pigments and Satellite Data
Mariana Altenburg Soppa,Takafumi Hirata,Brenner Silva,Tilman Dinter,Ilka Peeken,Sonja Wiegmann,Astrid Bracher +6 more
TL;DR: It is found that diatom may be more abundant in the Southern Ocean than previously thought and a new global model (ABAZpd) improved the estimation of diatoms abundance by 28% in the SO compared with the original ABA model.
Journal ArticleDOI
Controls of primary production in two phytoplankton blooms in the Antarctic Circumpolar Current

TL;DR: Two large-scale blooms observed during a cruise with R.V. Polarstern were investigated with respect to phytoplankton standing stocks, primary productivity and nutrient budgets, finding chlorophyll a –specific photosynthesis was more efficient in the bloom closer to the island of South Georgia compared to the open ocean bloom further east.
Journal ArticleDOI
Diatom Phenology in the Southern Ocean: Mean Patterns, Trends and the Role of Climate Oscillations
TL;DR: In the Ross Sea region, a later start of the bloom and lower diatom biomass were observed associated with El Nino and negative SAM events; likely influenced by an increase in sea ice concentration during these events.
Journal ArticleDOI
Global retrieval of phytoplankton functional types based on empirical orthogonal functions using CMEMS GlobColour merged products and further extension to OLCI data

TL;DR: In this article, an algorithm for globally retrieving chlorophyll a (Chl-a) concentrations of phytoplankton functional types (PFTs) from multi-sensor merged ocean color (OC) products or Sentinel-3A (S3) Ocean and Land Color Instrument (OLCI) data from the GlobColour archive in the frame of the Copernicus Marine Environmental Monitoring Service (CMEMS).
