Mixing genomics and geography yields insights into life and environment
In an upcoming issue of Proceedings of the National Academy of Sciences, Yale researchers used newly developed mathematical models to analyze huge amounts of data on physical characteristics such as temperature and salinity in different ocean habitats and metabolic activity in marine micro-organisms. view more (2009-01-23)
Study: 2004 tsunami was not first of large scale, awareness may improve future tsunami estimates
The deadly Indian Ocean tsunami of 2004, which claimed more than 200,000 lives, was not the first of its size to hit the region, according to new research by an international research team led by Dr. Karin Monecke, a former post-doctoral geologist at Kent State University. view more (2008-10-31)
Eddies Warm Up The Ocean
Eddies appear in the ocean like in the atmosphere. Atmospheric eddies are short-lived, extremely speedy, and often very hazardous. Oceanic eddies are slower and can be observed only with the use of special equipment, but these eddies gently mixing ocean waters affect the climate in general. For more than ten years specialists from the Pacific... view more... (2002-02-19)

Carbon turns over much faster through basal food-chain levels in aquatic than in terrestrial ecosystems
Global temperatures have increased dramatically over the past century, which is causing major impacts on climate patterns, ocean circulation and wildlife preservation. The increase in temperature is largely due to a rise of anthropogenic emissions of greenhouse gases, of which CO2 is one of the most important. To understand the capacity of... view more...

NASA study finds rising Arctic storm activity sways sea ice, climate
A new NASA study shows that the rising frequency and intensity of arctic storms over the last half century, attributed to progressively warmer waters, directly provoked acceleration of the rate of arctic sea ice drift, long considered by scientists as a bellwether of climate change. view more (2008-10-07)
Getting Warmer? Prehistoric Climate Can Help Forecast Future Changes
The first comprehensive reconstruction of an extreme warm period shows the sensitivity of the climate system to changes in carbon dioxide (CO2) levels as well as the strong influence of ocean temperatures, heat transport from equatorial regions, and greenhouse gases on Earth's temperature. view more (2008-11-25)
Protection zones in the wrong place to prevent coral reef collapse
Conservation zones are in the wrong place to protect vulnerable coral reefs from the effects of global warming, an international team of scientists warned today. view more (2008-08-27)
Climate gas could disrupt food chain
Levels of a climate cooling gas will change as carbon dioxide increases, affecting food webs along the way, said Dr Michael Steinke at a Science Media Centre press briefing today. view more (2007-12-11)
32-mile cable installed for first deep-sea observatory
Oceanographers have completed an important step in constructing the first deep-sea observatory off the continental United States. Workers in the multi-institution effort laid 32 miles (52 kilometers) of cable along the Monterey Bay sea floor that will provide electrical power to scientific instruments, video cameras, and robots 3,000 feet (900... view more...

Engineered weathering process could mitigate global warming
Researchers at Harvard University and Pennsylvania State University have invented a technology, inspired by nature, to reduce the accumulation of atmospheric carbon dioxide (CO2) caused by human emissions. view more (2007-11-08)
North Atlantic Fish Populations Shifting as Ocean Temperatures Warm
About half of 36 fish stocks in the Northwest Atlantic Ocean, many of them commercially valuable species, have been shifting northward over the last four decades, with some stocks nearly disappearing from U.S. waters as they move farther offshore, according to a new study by NOAA researchers. view more (2009-11-03)
Unstated assumptions color Arctic sovereignty claims
Settling the growing debate over ownership of Arctic Ocean resources is complicated by the fact that the various countries involved have different understandings of the geography of the place. view more (2009-05-29)
CO2 emissions could violate EPA ocean-quality standards within decades
In a commentary in the September 25, 2007, issue of the Geophysical Research Letters (GRL), a large team of scientists state that human-induced carbon dioxide (CO2) emissions will alter ocean chemistry to the point where it will violate U.S. Environmental Protection Agency Quality Criteria [1976] by mid-century if emissions are not dramatically... view more...

Plate tectonics may take a break
Plate tectonics, the geologic process responsible for creating the Earth's continents, mountain ranges, and ocean basins, may be an on-again, off-again affair. view more (2008-01-04)
Ocean floor geysers warm flowing sea water
An international team of earth scientists report movement of warmed sea water through the flat, Pacific Ocean floor off Costa Rica. The movement is greater than that off midocean volcanic ridges. The finding suggests possible marine life in a part of the ocean once considered barren. view more (2008-09-23)
Mystery Solved: Marine Microbe Is Source of Rare Nutrient
A new study of microscopic marine microbes, called phytoplankton, by researchers at Woods Hole Oceanographic Institution (WHOI) and the University of South Carolina has solved a ten-year-old mystery about the source of an essential nutrient in the ocean. view more (2009-09-30)
Ocean Cores May Give Clues On Climate Change
Core samples taken from far below the ocean floor are helping a University of Edinburgh geologist to form a picture of dramatic climate changes which took place 30 to 40 million years ago. Dr Bridget Wade is part of an international team of scientists studying climate shifts between the Eocene period - the warmest cycle in the last 65 million... view more... (2002-05-03)
North Pole's ancient past holds lessons for future global warming
Detailed information on greenhouse gasses and a subtropical heat wave at the North Pole 55 million years ago is providing information about the Earth's past as well as a portent for its future, according to reports in the June 1 issue of Nature. view more (2006-06-01)
Rapid Sea Level Rise in the Arctic Ocean May Alter Views of Human Migration
Scientists have found new evidence that the Bering Strait near Alaska flooded into the Arctic Ocean about 11,000 years ago, about 1,000 years earlier than widely believed, closing off the land bridge thought to be the major route for human migration from Asia to the Americas. view more (2006-10-12)
