They contributed to ice-age deep freeze

Labrador Sea ocean tides dislodged huge Arctic icebergs thousands of years ago, carrying gigantic ice-rafted debris across the ocean and contributing to the ice age’s deep freeze, say an international team of university researchers.

The study, published in the November issue of Nature, is the first to suggest that ocean tides contributed to enigmatic Heinrich events, a phenomenon where colossal discharges of icebergs periodicall

A new study has revealed a mechanism that counters established thinking on how the rate at which tectonic plates separate along mid-ocean ridges controls processes such as heat transfer in geologic materials, energy circulation and even biological production.

The study also pioneered a new seismic technique – simultaneously shooting an array of 20 airguns to generate sound — for studying the Earth’s mantle, the layer beneath the 10- to 40-kilometer-deep crust on the seaflo

Scientists have found the first direct evidence linking large-scale coastal farming to massive blooms of marine algae that are potentially harmful to ocean life and fisheries.

Researchers from Stanford University’s School of Earth Sciences made the discovery by analyzing satellite images of Mexico’s Sea of Cortez, also known as the Gulf of California-a narrow, 700-mile-long stretch of the Pacific Ocean that separates the Mexican mainland from the Baja California Peninsu

In 30 years, a nuclear-powered space exploration mission to Neptune and its moons may begin to reveal some of our solar system’s most elusive secrets about the formation of its planets — and recently discovered ones that developed around other stars. This vision of the future is the focus of a 12-month planning study conducted by a diverse team of experts led by Boeing Satellite Systems and funded by NASA. It is one of 15 “Vision Mission” studies intended to develop concepts in the United State

There is undeniable proof that water once existed on the planet Mars, a team of researchers has concluded in a series of 11 articles this week in a special issue of the journal Science.

A team of more than 100 scientists from numerous government agencies and universities, among them Mark Lemmon of Texas A&M University’s College of Geosciences, co-wrote the articles. Lemmon was the principal author on one article and co-author on three others describing the work of Spiri

The world’s fastest glacier, Greenland’s Jakobshavn Isbrae, doubled its speed between 1997 and 2003. The rapid movement of ice from land into the sea provides key evidence of newly discovered relationships between ice sheets, sea level rise and climate warming.

The findings were reported in the journal Nature on December 2, 2004. Co-authoring the study was University of New Hampshire glaciologist Mark Fahnestock of the Institute for the Study of Earth, Oceans, and Space (
