Cape Cod’s shellfish farmers face many challenges, and one of the biggest is dealing with harmful algal blooms, which can damage shellfish and be poisonous for humans to ingest. But a new project at the Woods Hole Oceanographic Institution is looking at a way to better manage this with the help of a tiny camera.
“Cyanobacteria grow quite well—better than almost everything else in those freshwater systems—the hotter it gets,” said Don Anderson, a senior scientist at WHOI.
South Andros Island, part of the Bahamian archipelago, is a sandy slice of paradise whose shores conceal buried geological treasures: blue holes. Hiding in the depths of these ethereal submarine sinkholes lay ancient sediment sandwiches whose layers betray the bygone passages of powerful hurricanes.
Federal and university scientists are trying to better understand why some birds and marine mammals have been unable to find enough food, and whether toxic algae blooms — increasing as the water warms — could have contributed or caused some of the die-offs.
Researchers have assembled a 1,500-year history of hurricanes in the Bahamas, based on sand and shell fragments pulled up from submarine caverns known as blue holes.

The study says that stormquakes are actually a fairly common occurrence, but they just sounded like seismic background noise and went undetected.
The general consensus of governmental agencies is that it takes polystyrene thousands of years to fully break down. But a new study shows that it may instead degrade in decades or centuries when exposed to sunlight.Read More
NOAA’s National Centers for Coastal Ocean Science recently announced funding for 12 new research projects to better understand and predict harmful algal blooms (HABs) and improve our collective response to them.Read More
Preparing to summarize and celebrate the 10-year Deep Carbon Observatory program at the National Academy of Sciences, Washington DC, Oct. 24-26, DCO’s 500-member Reservoirs and Fluxes team today outlined several key findings that span time from the present to billions of years past; from Earth’s core to its atmosphere, and in size from single volcanoes to the five continents.
Over the past year and as a student fellow in 2017, I have been working with Woods Hole Oceanographic Institution scientist Jeffrey Donnelly, who uses sediment cores—tubes of sand and mud layers that are extracted from coastal lake beds—to track ancient cyclones in the Atlantic and, recently, in the islands of the South Pacific.
In the 81 years since the 1938 storm, the sea level here has risen about a foot, said WHOI researcher Jeff Donnelly, and is now rising faster than it has in thousands of years.

BBC radio host Rhod Sharp and Jeff Donnelly of WHOI’s Coastal Research Lab trace the history of hurricanes in the Atlantic and discuss the frequency of intense storms. New sediment records indicate that historically unprecedented levels of intense hurricane activity impacted the eastern seaboard of the United States and northeastern Gulf Coast in the last two millennia.

The type of toxin released depends on the species causing the bloom. Some of the most common ones affect the liver or the nervous system, said Donald Anderson, director of the U.S. National Office for Harmful Algal Blooms and a senior scientist at WHOI.
“Trying to understand the big picture on plastic and be able to weave a story together is going to take decades,” said Christopher Reddy, an environmental chemist at Woods Hole Oceanographic Institution, who was not involved in the study.
