Satellites Stay Current On Ocean Currents
2012-05-04 03:09:15

Satellites offer a frequent overview of our entire planet — covered mostly by water — and provide valuable data to monitor and understand global ocean circulation. Understanding water currents at the ocean surface is important for many applications. Ocean surface currents have long fascinated oceanographers as they work to understand the role of oceans in the Earth system and how they affect our climate. Measurements of ocean surface currents are fundamental to a number of...

OceanWorks International has been awarded phases 1 and 2 of a 3 phase contract by Woods Hole Oceanographic Institution (WHOI) to assist with the re-certification of life support systems on the Deep Submergence Vehicle Alvin (DSV Alvin). Certification for manned diving operations will be provided under the authority of the U.S. Navy´s Naval Sea Systems Command (NAVSEA) and the American Bureau of Shipping (ABS). Burnaby, BC (PRWEB) April 30, 2012 The DSV Alvin is currently midway through...

Novel Method To Identify Sources Of Global Sea Level Rise
2012-04-24 11:08:34

As the Earth's climate warms, a melting ice sheet produces a distinct and highly non-uniform pattern of sea-level change, with sea level falling close to the melting ice sheet and rising progressively farther away. The pattern for each ice sheet is unique and is known as its sea level fingerprint. Now, a group of geophysicists from the University of Toronto, Harvard and Rutgers Universities have found a way to identify the sea level fingerprint left by a particular ice sheet, and possibly...

Ocean Acidification Linked With Larval Oyster Failure in Hatcheries
2012-04-13 03:43:11

Increase in ocean acidification led to collapse of oyster seed production at Oregon hatchery Marine researchers have definitively linked the collapse of oyster seed production at a commercial oyster hatchery in Oregon to an increase in ocean acidification. Larval growth at the hatchery declined to a level considered by the owners to be "non-economically viable." A study by the scientists found that increased seawater carbon dioxide (CO2) levels, resulting in more corrosive ocean...

Was The Dead Sea Once, In Fact, Dead?
2012-04-12 05:14:15

As towns and villages continue to use its run-off water, levels of the Dead Sea have continually been dropping for the past few years. However, according to new research, this may not be the only time the Dead Sea has shrunk, even without our help. In fact, it may have dried up almost entirely more than 100,000 years ago. Such a finding is troublesome for researcher Steven Goldstein, professor at the Lamont-Doherty Earth Observatory at Columbia University, reports Stephanie Pappas for...

Researchers at Oregon State University have definitively linked an increase in ocean acidification to the collapse of oyster seed production at a commercial oyster hatchery in Oregon, where larval growth had declined to a level considered by the owners to be “non-economically viable.” A study by the researchers found that elevated seawater carbon dioxide (CO2) levels, resulting in more corrosive ocean water, inhibited the larval oysters from developing their shells and growing...

Indonesian Earthquake: Update
2012-04-11 08:37:20

Lawrence LeBlond for RedOrbit.com Wednesday´s powerful 8.6-magnitude earthquake that struck off Indonesia´s western coast at 2:38 p.m. local time, was followed by fears of a tsunami, gripping a region that still had the 2004 tsunami -- one that ravaged numerous coastal communities along the Indian Ocean and killing more than 230,000 people -- fresh in their minds. But hours after the fears of a tsunami subsided, a strong 8.2-magnitude aftershock hit the region sparking a new...

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
2012-11-17 08:24:58

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...

mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
