Sediment accumulating on the bottom of the sea carries in it clues to the past, in the form of tiny shells, chemical compounds, and isotopes of elements that reflect climate…

Giant clams, Tridacna, can have colorful mantle tissue, including bright blue. Eight species of Tridacna, most threatened by over-harvesting, live in shallow waters of the South Pacific and Indian Oceans.…

In Ilulissat, a coastal town in western Greenland, people don’t have to walk far to see millions of tons of icebergs calving away from the glacier each year into Disko Bay. Scientists from WHOI…

WHOI geologist Sarah Das spent days this summer in Greenland looking for the perfect waterfall. Not to photograph or to take a really cold swim. She needed falling water for…

The research vessel Knorr rests in port in Nuuk, Greenland, in September 2007. The ship and crew arrived at the great island after deploying submerged autonomous launch platforms, or SALPs,…

Richard Camilli, a chemist and engineer in the WHOI Applied Ocean Physics and Engineering Department, builds cutting-edge instruments for sensing molecules in seawater. His miniature mass spectrometer “Gemini” (shown here)…

Senior research specialist Jim Broda of the Geology and Geophysics Department displays sediment cores and rocks from the WHOI Seafloor Samples Lab to a group of visiting journalists. This week,…

WHOI glaciologist Sarah Das (climbing to reach a temperature sensor) spent July 2008 in Greenland studying lakes that form when the ice surface melts each year. The goal of this project, and many…

A North Atlantic right whale dives astern of WHOI’s coastal vessel Tioga during a research cruise to study their feeding. Vulnerable to ship strikes and entanglement in fishing gear, the…

WHOI’s Towed Digital Camera and Multi-Rock Coring System—more commonly known as TowCam—is loaded onto the research vessel Wecoma in Newport, Oregon in mid-August 2008. WHOI research associate Erich Horgan (not…

WHOI biologist Simon Thorrold holds a fish otolith—an ear bone—that can serve as a natural tag to reconstruct the history of temperatures and seawater chemistry wherever a fish has lived.…

Retired WHOI research associate Bruce Tripp (right) explains the fundamentals of how to retrieve a seadiment core, as WHOI summer student fellow Amanda O’Rourke holds their latest catch. Every summer,…

There is an approved method of holding a penguin, with its head tucked under an arm. It’s called the rugby hold, so named because, from the front, the penguin’s torpedo-shaped…

Greenland’s ice sheet is pockmarked with cryoconites, or holes filled with melted water. They form when the Sun melts darker dust and silt on the ice sheet, creating round or irregular…

Science and a full life go hand-in-hand for Rudolf Scheltema and Amélie Scheltema, researchers in the WHOI Biology Department who together have devoted over a century to understanding the invertebrate…
