The terms “gas” and “sea” for many will invoke associations of reserves, business, and a lot of money. Whatever the association, most of the efforts in Israel´s energy field are being directed at gas buried deep under the Mediterranean seabed. Now a new geophysical study, the first of its kind in Israel, has uncovered a system of active gas springs in the Haifa Bay seabed, at relatively shallow depths, only a few dozen meters below the surface. The study,...

DEVOTES stands for "DEVelopment Of innovative Tools for understanding marine biodiversity and assessing good Environmental Status". DEVOTES is a four year project, which has a total budget of 12 million, of which 9 million are funded by the 7th Framework Programme of the European Union. DEVOTES is coordinated by Ángel Borja, from AZTI-Tecnalia, a Spanish technological centre, specialized in marine and food research. More than 250 scientists, from 23 research centers of 12...

Improving Wave Forecasts
2012-10-31 18:06:58

Lee Rannals for redOrbit.com — Your Universe Online Oceanographers from the U.S. Navy are using ocean wave research to help improve forecasts. Naval oceanography can provide information critical for combat disciplines, and today U.S. Naval Research Laboratory (NRL) physicists at the Remote Sensing Division will continue to improve the integrity of these forecasts. "Current state-of-the-art ocean wave forecasting numerical models do not take this mechanism into account," Dr....

Ecological Tipping Points Examined In Hopes Of Preventing Them
2012-10-31 09:26:37

University of California - Santa Barbara Predation by otters keeps urchin populations in check, allowing kelp —— a favorite food of urchins —— to flourish. But what if otters were harvested to near extinction for their fur? The resulting overabundance of urchins would decimate the kelp forest, leaving little food or shelter for fish and invertebrates. And so it may go, as declines in these species are likely to affect others. Such is the potential trickle-down...

Earthquake In British Columbia Leads To Tsunami Warnings
2012-10-28 07:07:05

redOrbit Staff & Wire Reports - Your Universe Online A magnitude 7.7 earthquake struck the Canadian province of British Columbia late Saturday night, leading to short-lived tsunami warnings and mass evacuations as far away as Hawaii, according to various media reports. The earthquake was centered in the Queen Charlotte Islands area (also known as Haida Gwaii) of British Columbia, US Geological Survey (USGS) officials told Mark Thiessen and Oskar Garcia of the Associated Press (AP),...

Ocean Acoustics Changing
2012-10-19 14:07:43

Brett Smith for redOrbit.com - Your Universe Online Along with negatively impacting marine life and global climate change, the acidification of the Earth´s oceans could have the unintended side effect of changing the acoustics beneath the water´s surface. New research suggests that a future, more acidic ocean would resemble the one that existed around 110 million years ago, when dinosaurs still roamed both the land and sea. Climatologists have been raising concerns in recent...

Gulf Stream Shift Has Warmed New England Waters
2012-10-13 10:00:29

redOrbit Staff & Wire Reports - Your Universe Online The ocean waters around the New England continental shelf were warmer than usual thanks to a divergence in the Gulf Stream path that started about one year ago, researchers from the Woods Hole Oceanographic Institution (WHOI) announced on Thursday. The study, which was published in the August edition of the journal Scientific Reports, began after local commercial fisherman met with WHOI members and alerted them to unusually high...

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...
