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...

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...

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...

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...

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...

Ocean Current Impacts On Weather
2012-07-30 13:25:48

The Peru Current flows from South to North along the western side of South America. This current transports colder air from the south northward towards the equator. This current is responsible for bringing cooler waters off the coast of Peru which is a big reason that they have such high fishing success. However this current can get altered during EL-Nino when the warmer waters of the Pacific...

The Gulf Stream Ocean Current
2012-07-16 15:25:39

Image Credit: F-5 Weather Data The Gulf Stream is a warm ocean current that travels from the East Coast of Florida all the way northward along the Eastern Seaboard until it gets near North Carolina and Virginia then it starts to make its way back eastward out to sea. The significant impact of this ocean current, as you can see in the image above, is that the waters are warm and this...

Wetsuit
2010-11-19 16:36:05

A wetsuit, worn by divers, windsurfers, and others engaged in water sports, is a garment, made of foamed neoprene that provides thermal insulation, abrasion resistance, and buoyancy. The suit provides insulation through bubbles of gas enclosed within the material which reduces its ability to conduct heat. These bubbles also provide buoyancy in water. Contrary to popular belief the layer of warm...

Bairdi Crab
2008-05-05 22:38:10

The Bairdi Crab or Tanner Crab (Chionoecetes bairdi), is a species of crab found in the Bering Sea. It is closely related to the Opilio Crab, which also is found in the Bering Sea. Their appearance is similar, and Opilio and Bairdi can be difficult for a person not familiar with the two species to distinguish. Bairdi Crab were largely fished from 1996 to 2006. Restrictions were put in place...
