Pacific Ocean 'Garbage Patch' Increasing At Alarming Rate
2012-05-09 09:16:49

Brett Smith for RedOrbit.com Plastic trash has been accumulating in the Pacific Ocean at an alarming rate and its effects are reverberating throughout the ecosystem, according to a new study by researchers at Scripps Institution of Oceanography at UC San Diego. The  study, published in the May 9 online issue of the journal Biology Letters, found that plastic trash in the "Great Pacific Garbage Patch" has increased by 100 times over in the past 40 years.  Experts disagree over...

Groundwater Pumping Leads To Sea Level Rise
2012-05-09 07:44:38

As people pump groundwater for irrigation, drinking water, and industrial uses, the water doesn´t just seep back into the ground – it also evaporates into the atmosphere, or runs off into rivers and canals, eventually emptying into the world´s oceans. This water adds up, and a new study calculates that by 2050, groundwater pumping will cause a global sea level rise of about 0.8 millimeters per year. “Other than ice on land, the excessive groundwater extractions are...

Greenland Glacier Acceleration Levels Less Than Originally Feared
2012-05-04 06:55:11

Some of Greenland's glaciers are moving approximately 30% faster than they were a decade ago, contributing to the rising sea level but not reaching worst-case speed levels that experts once feared, a new study published in Friday's edition of the journal Science has discovered. According to Reuters reporter Deborah Zabarenko, researchers at the University of Washington (UW) and Ohio State University (OSU) studied satellite data from 2000 to 2011. They focused on more than 200 glaciers and...

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...

WASHINGTON, April 25, 2012 /PRNewswire-USNewswire/ -- Warm ocean currents attacking the underside of ice shelves are the dominant cause of recent ice loss from Antarctica, a new study using measurements from NASA's Ice, Cloud, and land Elevation Satellite (ICESat) revealed.

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...

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...
