2017 Forecasts: Dead Zones, Harmful Algal Blooms, Coral Bleaching
Significant summer harmful algal bloom predicted for western Lake Erie (July 2017)
NOAA and its research partners predict that western Lake Erie will experience a significant harmful algal bloom this summer, potentially reaching levels last seen in 2013 and 2014, though smaller than the record bloom of 2015.
Global coral bleaching event likely ending (June 2017)
After analyzing satellite and model data, NOAA’s experts say coral reefs around the world may finally catch a break from high ocean temperatures that have lingered for an unprecedented three years, the longest period since the 1980s.
NOAA, USGS and partners predict third largest Gulf of Mexico summer ‘dead zone’ ever (June 2017)
Federal scientists forecast that this summer’s Gulf of Mexico dead zone — an area of low to no oxygen that can kill fish and other marine life — will be approximately 8,185 square miles, or about the size of New Jersey.
NOAA, USGS and partners predict larger summer ‘dead zone’ for Chesapeake Bay (June 2017)
Scientists expect this year’s summer Chesapeake Bay hypoxic or “dead zone”— an area of low to no oxygen that can kill fish and aquatic life — will be larger than average, approximately 1.89 cubic miles, or nearly the volume of 3.2 million Olympic-size swimming pools.
Small Bloom Predicted for Gulf of Maine Red Tide in 2017 (May 2017)
This summer the Gulf of Maine red tide is predicted to be relatively small with limited impacts, as forecast by researchers at NOAA, Woods Hole Oceanographic Institution (WHOI), and North Carolina State University, continuing the pattern of smaller blooms seen over the last three years.
California Estuary Harmful Algal Bloom Monitoring Begins (January 2017)
In January, NCCOS-sponsored scientists began harmful algae and algal toxin monitoring in California estuaries. The monitoring is part of a collaborative NOAA–state response to recent research showing that a mixture of marine and freshwater toxins can reside in estuarine waters. The research found that this toxic "cocktail" could also be fatal to shellfish, sea otters, and other animals in these habitats.
