Scientists from the Woods Hole Oceanographic Institution (WHOI) are kicking off an innovative NOAA-funded pilot program using robotic instruments and computer modeling analysis to shed light on changing ocean conditions in the Gulf of Maine as they relate to the harmful algal bloom (HAB) phenomenon commonly known as the New England red tide.

The red tide is caused by the germination of dormant cysts of alga called Alexandrium fundyense, which produces a toxin that can cause paralytic shellfish poisoning (PSP). These cysts are found in bottom sediments and near-bottom waters, accumulating in “seedbeds” that serve as the source of swimming, rapidly dividing cells that form the blooms each spring. (more…)

*Brown Tide Culprit Uniquely Suited to Thrive in Environmentally Impacted Estuaries*

The microscopic phytoplankton Aureococcus anophagefferens, which causes devastating brown tides, may be tiny but it’s a fierce competitor.

In the first genome sequencing of a harmful algal bloom species, researchers found that Aureococcus’ unique gene complement allows it to outcompete other marine phytoplankton and thrive in human-modified ecosystems, which could help explain the global increases in harmful algal blooms (HABs).
