Unexpected Plume Challenges Iron Estimates
2013-08-20 08:47:27

A vast plume of iron and other micronutrients more than 620 miles long has been discovered billowing from hydrothermal vents in the South Atlantic Ocean. Teams of scientists say their findings call into question past estimates of iron abundances in the world’s seas.

Corals can survive the early stages of their development even under the tough conditions that rising carbon emissions will impose on them says a new study from the ARC Centre of Excellence for Coral Reef Studies.

USGS Maps California Seafloor In Unprecedented Detail
2013-08-12 14:59:57

While California offers an impressive shoreline, new research has been able to look beyond just the surface and has been used to reveal the hidden seafloor in unprecedented detail.

Underwater Volcano System Proposed As National Park For Norway
2013-08-05 05:11:28

Off the coast of Norway, on the floor of the Arctic Ocean, lies a largely unexplored world of undersea volcanoes. This system, with the fanciful name of Loki's Castle, contains rich metal deposits and unique wildlife.

Coastal American Cities Threatened By Sea-Level Rise
2013-07-31 08:55:40

Boston, Miami, New York and 1,700 American cities are facing a greater risk from rising sea levels than had previously been estimated

How Cold, Deep Ocean Waters Influence Sea Surface Temperatures
2013-07-26 06:04:28

Newly published research from Oregon State University has revealed new details on the forces behind El Nino and could lead to more refined predictions for global warming.

New Variability In Iron Supply To The Oceans With Climate Implications Discovered By Scientists
2013-07-19 09:44:51

The supply of dissolved iron to oceans around continental shelves has been found to be more variable by region than previously believed -- with implications for future climate prediction.

Scientists Create Global Atlas On Oceanic Plankton
2013-07-19 10:05:40

An international group of scientists has created a global atlas of oceanic plankton -- from bacteria to krill -- by recording times, places and concentrations of plankton occurrences.

Russia Blocks Antarctic Sanctuary
2013-07-17 08:34:56

Russia has blocked attempts to establish marine reserves in the Ross Sea and Eastern Antarctica, preventing the formation of what would have become the world's largest ocean sanctuary.

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...
