NASA-funded researchers are making final preparations at the Woods Hole Oceanographic Institution (WHOI) in Woods Hole, Mass., for an ocean-going campaign designed to shed new light on the link between ocean salinity and shifts in global precipitation patterns. Reporters are invited to attend a media briefing on the expedition at 10 a.m. EDT, Wednesday, Sept. 5, at WHOI. Media also can participate via telephone. NASA's field campaign, named the Salinity Processes in the Upper Ocean...

Lawrence LeBlond for redOrbit.com - Your Universe Online Why do some tsunamis, such as the devastating one that struck Japan in March 2011, occur on a much larger scale than scientists expect? The answer, based on a model developed by researchers at the University of Cambridge, lies within the “pop-up” movement of large amounts of sediment. Undersea earthquakes can release huge amounts of energy as tectonic plates slip across each other´s ridge lines. A study in Earth...

Unless Drastic Protection Policies Are Put In Place Marine Species Are At Risk
2012-08-21 13:56:55

redOrbit Staff & Wire Reports - Your Universe Online If the levels of carbon dioxide continue to increase many marine species will be harmed or won't survive It is doubtful that the current protection policies and management practices will be enough to save them. If various marine species are to survive, unconventional, non-passive methods to conserve marine ecosystems need to be considered. A group of scientists led by University of California, Santa Cruz researcher and...

Baffin Bay
2013-04-18 13:21:50

Baffin Bay, which is located between Baffin Island and the southwest coast of Greenland, is a marginal sea of the North Atlantic Ocean. It’s connected to the Atlantic by Davis Strait and the Labrador Sea. A narrower Nares Strait connects the Baffin Bay with the Arctic Ocean. The Baffin Bay is an arm of the Atlantic Ocean that is bordered by Baffin Island towards the west, Greenland towards the east, and Ellesmere Island towards the north. It is connected to the Atlantic through the Davis...

Current Sea Level Rise
2013-04-01 10:39:21

The sea levels all around the world are rising. Current sea-level rise has the potential to affect human populations and the natural environment. Two key factors have contributed to the observed sea level rise. The first is thermal expansion: as the ocean water warms, it expands. The second is from the influence of land-based ice because of increased melting. The major store of water on land is found in the glaciers and the ice sheets. The rising of sea levels is one of several lines of...

Ocean Acidification
2013-04-01 10:32:20

Ocean acidification is the name that was given to the ongoing decrease in the pH of Earth’s oceans, a cause of the uptake of anthropogenic carbon dioxide from the atmosphere. About 30 to 40 percent of the carbon dioxide that is released by humans into the atmosphere dissolves into the lakes, oceans, and rivers. To maintain the chemical equilibrium, some of it reacts with the water to create carbonic acid. Some of these extra carbonic acid molecules react with a water molecule to provide a...

Basic Ocean Terms
2013-02-05 12:52:11

Image Credit: Meteorologist Joshua Kelly When meteorologists are forecasting for ocean-going vessels, there are a few terms that we need to understand. The first term is wavelength. Wavelength is defined as the distance between two crests or between two troughs as seen in the image above. The example above highlights the crest to crest concept of wavelength. The next term that we use is wave height, and to determine this, we first must look at the wave when it passes our station. When...

Ocean Analysis for November 17, 2012

Point #1: Warm finger- This region inside the area marked number 1, represents a warm finger of the ocean temperatures. What is occurring is that the warmer air is being pushed faster in this region than the surrounding locations giving us this little finger of warmer temps in that region. Point #2: Warm Eddie- This is a region of warmer temps surrounded on all sides by colder water. Eddies are a closed circulation of water in the ocean that has in this case warmer temps around it. These...
