A WHOI research team has uncovered evidence of explosive volcanic eruptions deep beneath the ice-covered surface of the Arctic Ocean. Such violent eruptions of splintered, fragmented rock—known as pyroclastic deposits—were not thought possible at great ocean depths because of the intense weight and pressure of water and because of the composition of seafloor magma and rock.
In Computer Models and Seafloor Observations, Researchers See Potential for Significant 2008 "Red Tide" Season
Researchers from WHOI and North Carolina State University are preparing for a potentially big bloom of harmful algae in New England waters this spring. A combination of abundant beds of algal seeds and excess winter precipitation have set the stage for an Alexandrium bloom similar to the historic “red tide” of 2005. Weather patterns and ocean conditions over the next few months will determine whether this year’s algal growth affects coastal shellfishing.
Through the use of an automated, underwater cell analyzer developed at WHOI, researchers and coastal managers were recently able to detect a bloom of harmful marine algae in the Gulf of Mexico and prevent human consumption of tainted shellfish.
Examining more than 50,000 seafloor images, geologists have created the most detailed map ever assembled for a volcanic eruption along a fast-spreading mid-ocean ridge.
Many earthquakes in the deep ocean are much lower in magnitude than expected. Geophysicists from the Woods Hole Oceanographic Institution (WHOI) have found new evidence that the fragmented structure of seafloor faults and previously unrecognized volcanism may be dampening the effects of these quakes.
The frequency of intense hurricanes in the Atlantic Ocean appears to be closely connected to long-term trends in the El Niño/Southern Oscillation and the African monsoon, according to new research from the Woods Hole Oceanographic Institution (WHOI). Geologists Jeff Donnelly and Jonathan Woodruff made that discovery while assembling the longest-ever record of hurricane strikes in the Atlantic basin.
A new mooring and seismic monitoring system will significantly improve
the ability of natural hazard managers to protect the residents of Grenada from gases, eruptions, and tsunamis
caused by the Kick'em Jenny volcano.
When the levees broke in New Orleans after Hurricane Katrina, officials feared that Lake Pontchartrain might be infiltrated with disease-causing microbes from a “toxic gumbo” of water, polluted sediments, and sewage.
A new observation and modeling program focused on the southern Gulf of Maine and adjacent New England shelf waters could aid policymakers in deciding whether or not to re-open, develop, and manage offshore shellfish beds with potential sustained harvesting value of more than $50 million per year.
The public will have an opportunity to hear a first-hand account of
the catastrophe, the lessons learned, and recent developments in
disaster warning programs around the world.
Dramatic new video of a long-term volcanic eruption in the western Pacific first discovered in 2004 has been captured during a recent cruise by the remotely operated vehicle JASON, developed and operated by WHOI’s Deep Submergence Laboratory.
WHOI scientists have completed two extensive survey and mapping efforts to better understand why the 2005 New England red tide was so severe and to suggest what might lie ahead.
Advances in understanding basic earthquake processes have been limited by available instrumentation, but researchers have solved that problem by developing a device that records both small and large earthquakes at the same time.
With hurricane season arriving June 1, along with predictions of an above normal number of major storms in the Atlantic and Gulf States, understanding how the ocean and atmospheric interact and what role changing climate has on the formation of hurricanes is critical.
Faced with a "perfect storm" of red tide, WHOI scientists share data quickly with public health officials
Predicting when large earthquakes might occur may be a step closer to reality, thanks to a new study of undersea earthquakes in the eastern Pacific Ocean.
Scientists from WHOI and USGS Menlo Park will be assessing future earthquake risk in Algeria and training Algerian researchers under a new two-year project funded by the Office of Foreign Disaster Assistance (OFDA) of the United States Agency for International Development (USAID).
Major earthquakes have struck the Caribbean through history, and WHOI scientists warn this raises the possibility of a tsunami in the populous region
Scientists from the Chilean Navy Hydrographic and Oceanographic Office (SHOA), in cooperation with the Woods Hole Oceanographic Institution (WHOI), deployed a SHOA tsunami warning buoy off Northern Chile in the Pacific in December 2004 just prior to the devastating Indian Ocean tsunami.
Reconstructing the history and intensity of hurricanes is useful when assessing future risks of these extreme events in coastal regions. Previous studies of North Atlantic hurricane activity have identified many of the environmental factors that presently influence tropical cyclone activity.
