A new study published in the journal Science Advances changes our understanding of how volcanic arc lavas are formed, and may have implications for the study of earthquakes and the risks of volcanic eruption.
New England’s spring and summer red tides will be similar in extent to those of the past three years, according to the 2015 Gulf of Maine red tide seasonal forecast.
A new study of prehistoric hurricanes shows the intensity and frequency of hurricanes the U.S. could experience could intensify as ocean temperatures increase with climate change.
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.
In a study published this week in Nature Geoscience, scientists provide a new model for understanding the geological source of silent earthquakes, or “creep events” along California’s San Andreas fault.
A new robotic sensor deployed by Woods Hole Oceanographic Institution (WHOI) in Gulf of Maine coastal waters may transform the way red tides or harmful algal blooms (HABs) are monitored and managed in New England. A second such instrument will be launched later this spring.
New scientific understanding of toxic algal blooms on Georges Bank, along with an at-sea and dockside testing protocol, has allowed fishermen to harvest ocean quahogs and surf clams in these offshore waters for the first time in more than two decades. The Georges Bank surf clam and ocean quahog fishery has an estimated annual value of $10 – 15 million.
New England is expected to experience a “moderate” red tide this spring and summer, report NOAA-funded scientists studying the toxic algae that cause blooms in the Gulf of Maine. Red tide is caused by an alga Alexandrium fundyense, which produces a toxin that can cause paralytic shellfish poisoning (PSP). Red tide occurs annually along some portions of the Gulf of Maine coast. This outlook is similar to the 2012 red tide which was moderate.
New England is expected to experience a “moderate” regional “red tide” this spring and summer, report NOAA-funded scientists working in the Gulf of Maine to study the toxic algae that causes the bloom. The algae in the water pose no direct threat to human beings, however the toxins they produce can accumulate in filter-feeding organisms such as mussels and clams — which can cause paralytic shellfish poisoning (PSP) in humans who consume them.
WHOI Receives $1Million from Keck Foundation for First Real-Time Seafloor Earthquake Observatory at Cascadia Fault
A $1 million grant to WHOI from the W. M. Keck Foundation will fund the first seafloor geodesy observatory above the expected rupture zone of the Pacific Northwest’s Cascadia fault – an offshore, subduction zone fault capable of producing a magnitude 9 earthquake and generating a large tsunami.
Japan’s recent magnitude 9.0 earthquake, which triggered a devastating tsunami, relieved stress along part of the quake fault but also has contributed to the build up of stress in other areas, putting some of the country at risk for up to years of sizeable aftershocks and perhaps new main shocks, scientists say.
Scientists from the NOAA-funded Gulf of Maine Toxicity (GOMTOX) project issued an outlook for a moderate regional bloom of a toxic alga that can cause ‘red tides’ in the spring and summer of this year, potentially threatening the New England shellfish industry. However, there are signs this year’s bloom could be suppressed by recent changes in ocean conditions in the Gulf of Maine.
A three-year study into the cause of local area red tides is set to begin March 21. A team of researchers from the National Park Service, U.S. Geological Survey, and Woods Hole Oceanographic Institution will be examining the cause of red tides in the Nauset Marsh Estuary and its embayments in Cape Cod, Mass.
While Japan’s 9.0-magnitude earthquake and accompanying tsunami represent a devastating natural disaster for the country’s residents, scientists should also seize upon the massive temblor as an important learning tool for future quakes around the world, including the Pacific Northwest coast of the United States, according to experts from the Woods Hole Oceanographic Institution (WHOI).
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.
Today, scientists from the NOAA-funded Gulf of Maine Toxicity (GOMTOX) project issued an outlook for a significant regional bloom of a toxic alga that can cause ‘red tides’ in the spring and summer of this year, potentially threatening the New England shellfish industry. This year’s bloom could be similar to the major red tides of 2005 and 2008, according to WHOI biologist Don Anderson, principal investigator of the GOMTOX study.
Oceanographers using the remotely operated vehicle (ROV) Jason discovered and recorded the first video and still images of a deep-sea volcano actively erupting molten lava on the seafloor.
Researchers Report Potential for "Moderately Large" Red Tide Outbreak in the Gulf of Maine Region for 2009
The potential for an outbreak of the phenomenon commonly called “red tide” is expected to be “moderately large” this spring and summer, according to researchers with the Woods Hole Oceanographic Institution and North Carolina State University.
Coral reefs around the world are in serious trouble from pollution, over-fishing, climate change and more. The last thing they need is an infection. But that’s exactly what yellow band disease (YBD) is—a bacterial infection that sickens coral colonies. Researchers at the Woods Hole Oceanographic Institution (WHOI) and colleagues have found that YBD seems to be getting worse with global warming and announced that they’ve identified the bacteria responsible for the disease.
Researchers analyzing the May 2008 Wenchuan earthquake in China’s Sichuan province have found that geological stress has significantly increased on three major fault systems in the region. The magnitude 7.9 quake on May 12 has brought several nearby faults closer to failure and could trigger another major earthquake in the region.
