Hypoxia Sustains Cyanobacteria Blooms in the Baltic Sea
Environmental Science & Technology, 2014 Nutrient over-enrichment is one of the classic triggering mechanisms for the occurrence of cyanobacteria blooms in aquatic ecosystems. In the Baltic Sea, cyanobacteria regularly occur in the late summer months and form nuisance accumulations in surface waters and their abundance has intensified significantly in the past 50 years attributed to human ...

Cyanobacteria Blooms in the Baltic Sea: A Review of Models and Facts [PDF]
Biogeosciences, 2020 Abstract. The ecosystem of the Baltic Sea is endangered by eutrophication. This has triggered expensive international management efforts. Some of these efforts are impeded by natural processes such as nitrogen-fixing cyanobacteria blooms that add bioavailable nitrogen to the already over-fertilised system and thereby enhance primary production, export ...

A Surface Bloom Sampler (SUBS) for cyanobacteria and algae [PDF]
, 2011 In surface blooms, cell density is not evenly distributed with depth but shows a vertical abundance gradient, dependent on the hydrodynamics of water body and on cell buoyancy.

Synechococcus and Other Bloom-Forming Cyanobacteria Exhibit Unique Redox Signatures
, 2021 Cyanobacteria form dense blooms that impair water quality. Although the impact of blooms on water quality largely differs depending on the species of cyanobacteria, it is challenging to distinguish cyanobacterial species with conventional sensors due to ...

Hindcasting cyanobacterial communities in Lake Okaro with germination experiments and genetic analyses [PDF]
, 2009 Cyanobacterial blooms are becoming increasingly prevalent worldwide. Sparse historic phytoplankton records often result in uncertainty as to whether bloom-forming species have always been present and are proliferating in response to eutrophication or ...

THE BLOOM AND TOXICITY OF CYANOBACTERIA IN LAKE SEVAN
Proceedings of the YSU B: Chemical and Biological Sciences, 2020 Seasonal hydrochemical, hydrophysical, and phytoplankton studies were conducted in a littoral zone of Lake Sevan in 2019. It is known that in recent years widespread algal blooms were usually started from the littoral zone of Big Sevan, and then spread towards the pelagic zone of the lake.

Recent occurrence of Cylindrospermopsis raciborskii, in Waikato lakes of New Zealand. [PDF]
, 2003 Cylindrospermopsis raciborskii is a toxin-producing species of cyanobacteria that in autumn 2003 was recorded for the first time in three shallow (max. depth ≤5 m) Waikato lakes and a hydro-electric dam on the Waikato River, New Zealand.
