Suffocating phytoplankton, suffocating waters - red tides and anoxia

Frontiers in Marine Science, 2016
The dynamics of O2 depletion in exceptional dinoflagellate blooms, often referred to as red tides or harmful algal blooms (HABs), was investigated in St Helena Bay in the southern Benguela upwelling system in 2013.

MODIS-derived green Noctiluca blooms in the upper Gulf of Thailand: Algorithm development and seasonal variation mapping

Frontiers in Marine Science, 2023
In recent decades, red tides of non-toxic harmful algal blooms have frequently occurred in monsoon-influenced tropical areas, particularly the green form of Noctiluca scintillans (hereafter green Noctiluca). However, our understanding of the mechanism of

When the Red Tide Rolls In: A Red Tide Associated Angioedema Case Report [PDF]

Clinical Practice and Cases in Emergency Medicine, 2021
Introduction: Histamine-mediated angioedema is a potentially life-threatening reaction following exposures that incite mast cell activation. In Florida, red tides are a frequent phenomenon caused by overgrowth of the harmful algae species Karenia brevis, which contain environmentally detrimental brevetoxins.
