Phytoplankton Patterns and Processes in a Tropical-Subtropical Transition Region: Santa Catarina Coast, Southern Brazil

Marine Heatwaves, Sewage and Eutrophication Combine to Trigger Deoxygenation and Biodiversity Loss: A SW Atlantic Case Study

“…The greater taxon richness outside the bay, also with greater relative importance of dinoflagellates (Dinophyceae), shows a less restrictive environment, with more diversity of ecological niches. Moreover, some studies have also shown an increase in harmful algal blooms in the region, possibly related to the degradation of water quality and anomalous meteo-oceanographic events (Proença et al, 2017;Rörig et al, 2018).…”

Evaluation of ocean chlorophyll-a remote sensing algorithms using in situ fluorescence data in Southern Brazilian Coastal Waters

“…TS-diagrams have shown that La Plata plume waters had a more pronounced influence in 2018 than in 2019 (Figure 5b). A close inspection of monthly mean sea surface temperature and chl-a surface concentration images of July 2017, 2018 showed that indeed the stronger intrusion of cold and less saline waters happened in 2018 with higher chl-a surface concentrations. Most of the time, the studied region was occupied by STSW water, with influence of TW in summer and PPW in wintertime.…”

“…It is important to highlight the social and economic significance of studies related to the distribution patterns of phytoplankton biomass and its associated processes in the Santa Catarina coast region, as articulated by Rörig et al (2018). The authors identified that the structure of the phytoplankton communities, and their distribution, are caused by the influence of river discharge, the phenomenon of Silva & Garcia coastal resurgence, and seasonal variation in the distribution of water mass in the region.…”
