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 Ni?o/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.

Scientists “See” New Ocean Floor Just Before and After It Is Created

A multidisciplinary research team from six institutions has for the first time successfully anticipated and then chronicled a seafloor eruption along the global mid-ocean ridge, the most active volcanic system on Earth. The event along the East Pacific Rise has provided researchers from Woods Hole Oceanographic Institution (WHOI) with a rare opportunity to observe what happens in the immediate aftermath of an eruption.

Worlds Apart, But United by the Oceans

Jian Lin came of age in an era of both geological and political seismic shifts in China, experiencing the deadliest earthquake in the 20th century in Tangshen in 1976 and the Cultural Revolution in the 1970s. Then he immigrated to America and came full circle in 2005 to become the first U.S. scientist to co-lead a Chinese deep-sea research cruise.

Analyzing Ancient Sediments at Warp Speed

Analyzing Ancient Sediments at Warp Speed

Like a toy out of a science fiction story, the X-ray fluorescence core scanner reveals intimate details of the composition of ancient mud and sediment–which can contain a variety of clues about past climate and environmental conditions on Earth–without breaking the surface. In a matter of hours, the XRF simultaneously captures digital photographs and X-ray images of every millimeter of a core sample, while detecting the presence of any of 80 chemical elements.

Nafanua, Eel City, and the Crater of Death

WHOI geochemist Stan Hart and colleagues have discovered a fast-growing volcano, dubbed Nafanua, inside the crater of Vailulu’u, a 14-300-foot active volcano that should begin the next island in the Samoan chain. They also found a novel hydrothermal community, which they named “Eel City,” and a lifeless zone in the caldera, which they call the “Crater of Death.”

The Once and Future Danube River Delta

The Once and Future Danube River Delta

?The Danube River Delta is like the Everglades,? said Liviu Giosan, who grew up near the Romanian wetlands. The triangle-shaped, sediment-rich region at the mouth of the Danube River is also rich with human history. A traditional maritime culture persists on the delta, and the United Nations has declared the region a World Heritage site. The Danube Delta is also a great place for a geologist to study how the coast stretches, contracts, and undulates with time?and human interference.

Rambling Atop an Active Volcano to Detect Telltale Rumbling Within It

With machete in hand and 60 pounds of satellite receiver and tripod on his back, Jeff Standish looked up into the lush tropical brush that covered the volcano, up a steep escarpment, and up again to the summit 3,000 feet above sea level. Then he turned to Rhea Workman, a graduate student in the WHOI/MIT Joint Program, and said, “We’re going up where?”

Rapid Response

The earthquakes were coming fast and frequent, as many as 50 to 70 an hour. On the morning of Sunday, Feb. 28, undersea hydrophones began detecting the most intense swarm of earthquakes to occur in the last three years along the Juan de Fuca Ridge, about 200 miles off the Pacific Northwest coast.
