Geologists Discover Signs of Volcanoes Blowing their Tops in the Deep Ocean

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.

Underwater Microscope Helps Prevent Shellfish Poisoning Along Gulf Coast of Texas

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.

Researchers Compile Most Detailed Map of an Underwater Eruption

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.

Fragmented Structure of Seafloor Faults May Dampen Effects of Earthquakes

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.

WHOI Geologists Compile Longest Ever Record of Atlantic Hurricane Strikes

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.

Real-Time Seismic Monitoring Station Installed Atop Active Underwater Volcano

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.

Hurricane Katrina’s Flood Legacy Does Not Include Disease

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.

Harmful Algal Bloom (Red Tide) Models and Forecasts to be Expanded in Gulf of Maine

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.

Lessons from the 2004 Indian Ocean Tsunami Topic of Public Forum

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.

Smoke and Sulfur: Undersea Vehicle Captures Footage of Volcanic Eruption

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.

New Maps Provide Clues to the Historic 2005 Red Tide Outbreak in New England And Hints for 2006

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.

New Instrumentation May Help Scientists Understand Earthquake Mechanics

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.

Hurricanes and the Coastal Zone

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.

WHOI Scientists Monitor Largest Red Tide Outbreak in 12 Years in Massachusetts Bay

Faced with a "perfect storm" of red tide, WHOI scientists share data quickly with public health officials

Deep-Sea Tremors May Provide Early Warning System for Larger Earthquakes

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.

Assessing Algerian Earthquake Risk

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 Caribbean Earthquakes and Tsunamis a Real Risk

Major earthquakes have struck the Caribbean through history, and WHOI scientists warn this raises the possibility of a tsunami in the populous region

Tsunami Warning Buoy Deployed off Chile

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.

Clues from Past Hurricanes Help Assess Future Storm Risks

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.
