Somewhere in the North Pacific, about two kilometres below the ocean surface, is seawater that has remained in a mysterious shadow zone for over 1,000 years.Read more
In 2012, scientists from the Monterey Bay Aquarium Research Institute (MBARI) discovered a hydrothermal vent field along the Alarcón Rise at the southern end of the Gulf of California.Read more
Coral colonies of P. cylindrica have a unique internal solution to the problem of forming their skeletons and building reef structure in the face of rising ocean acidification.Read more
In the past, coral research has focused on radar and sonar mapping of the seafloor. With this kit, which is being used for the first time, biological samples can also be collected for analysis.Read more
Scientists used a float to follow a patch of seawater off Iceland. They observed the progression of the bloom by taking measurements from multiple platforms.Read more
Oceanographer Robert Ballard and his team were exploring the Gulf of Mexico for E/V Nautilus, an expedition to map the Galapagos Rift and gain a better understanding of how life develops around hydrothermal vents on the ocean floor.Read more
Analysis of the samples taken from subglacial Lake Whillans, the researchers indicate, show that the water contains a diverse microbial community, many members of which can mine rocks for energy and use carbon dioxide as their source of carbon.Read more
Nereus was sent to complete the first systematic study of the Kermadec Trench.
Thirty days into the forty-day mission, about seven hours into a nine-hour dive, communications with Nereus were lost. When standard emergency recovery protocols were unsuccessful, the team initiated a search near the dive site. They then spotted several pieces of debris on the surface nearby later identified to be a parts of Nereus, indicating a catastrophic implosion.
Nereus was a flagship ocean explorer for the US science community.Read more
Biosphere mixing appears to provide about one third the power required to bring the deep, cold waters of the world ocean to the surface, which in turn completes the ocean's conveyor belt circulation critical to the global climate system.Read more
“We discovered that a number of animals thought to be rare are common around the corals, documented many animals outside of their previously known ranges, and discovered species new to science,” NOAA zoologist Martha Nizinski said.
The absorbtion of CO2 may have slowed global warming, but there has been a resulting change in seawater chemistry. To understand why the effect of increasing atmospheric CO2, which leads to increased absorbtion of CO2 in sea water, is important, it is necessary to understand some of the chemistry of carbonic acid and its salts. However, before we can discuss the effect of this acidity, we must have a useful description of what we mean by acidity and acid strength. The most common and useful unit to describe the magnitude of acidity is the pH value.Read more
