Toxic benthic mats of cyanobacteria are associated with water quality problems and animal poisonings around the world. A strain filamentous cyanobacterial genus Kamptonema was isolated from a bloom in Baltic Sea four decades ago later shown to produce cylindrospermopsins. However, exact habitat this remains unclear cylindrospermopsins have not yet been reported blooms Sea. Here, we report isolation sp. UHCC 0994 microbial mat collected shallow on coast Helsinki.

In situ, satellite and reanalysis data from numerical models were used to study the characteristic features of Chl variability in Baltic Sea. The analysis is focused on years 2003–2020 when regular observations ocean color with MODIS AQUA are available.

Abstract Nitrogen fixers, or diazotrophs, play a key role in the nitrogen and carbon cycle of world oceans. Diazotrophs are capable utilising atmospheric dinitrogen which is competitive advantage over generally faster growing ordinary phytoplankton nitrogen-depleted conditions sun-lit surface ocean. In this study we argue that additional advantages must be at order to explain dynamics distribution diazotrophs global Backed by published evidence test effects preferential grazing (where zooplankton partly avoids diazotrophs) high-affinity diazotrophic phosphorus uptake an Earth System Model intermediate complexity. Our results illustrate these fundamentally different model assumptions result very similar match observation-based estimates fixation while, same time, they imply trajectories into our warming future. The latter applies biomass, rates as well ratio two. We conclude more comprehensive understanding competition between will reduce uncertainties model-based projections oceanic N cycle.

The aim of this study was to test and develop the indicators for remote sensing assessment cyanobacterial blooms as an input estimation eutrophication environmental status (ES) under Marine Strategy Framework Directive (MSFD) in optically varying Estonian coastal regions (the Baltic Sea). Here, cyanobacteria considered chlorophyll-a (chl-a), turbidity, biomass N2-fixing cyanobacteria. Sentinel-3 A/B Ocean Land Colour Instrument (OLCI) data Case-2 Regional CoastColour (C2RCC) processor were used chl-a turbidity detection. ES assessed using four methods: Phytoplankton Intensity Index (PII), Cyanobacterial Surface Accumulations (CSA), two variants Bloom Indicator (CyaBI) either with situ-measured or satellite-estimated biomass. threshold values each area are presented. During 2022, NW Gulf Riga reached good ES, but most 16 areas failed achieve according one multiple indices. Overall, CyaBI gives comprehensive blooms, (in situ) being best suited naturally turbid areas. (satellite) could be more useful than situ large open areas, where coverage sampling is insufficient.
