NASA Administrator Charles Bolden will speak with astronaut Dottie Metcalf-Lindenburger, commander of the 16th NASA Extreme Environment Mission Operations (NEEMO) mission, and her fellow crewmate Timothy Peake of the European Space Agency at 4:10 p.m. EDT Wednesday, June 20 as they perform their final "spacewalk" of the mission, 63 feet below the ocean's surface. The administrator's call to the crew will air live on NASA Television. The NEEMO 16 crew has been simulating asteroid...

SeaOrbiter To Study World's Oceans
2012-06-18 14:19:59

Brett Smith for redOrbit.com As the International Space Station drifts across the sky, a companion craft might be doing the same across the oceans as early as next year. Conceived in part by French architect Jacques Rougerie, the SeaOrbiter craft will be a mostly self-sustainable, half-submerged floating laboratory. Currently, the SeaOrbiter scale model and concept is the centerpiece of the French pavilion at the Expo2012 in Yeosu, South Korea and is slated for construction in October....

NASA Celebrates First Birthday For Aquarius
2012-06-14 06:46:49

Aquarius, NASA's pioneering instrument to measure ocean surface salinity from orbit, launched a year ago (on June 10, 2011) aboard the Argentine Space Agency's Satélite de Aplicaciones Científicas (SAC-D) observatory. Designed to advance our understanding of what changes in the saltiness of the ocean's top layer say about the water cycle and variations in climate, the mission has had a busy first year. Already, its measurements of global salinity patterns have...

China announced on Monday that its Jiaolong deep-sea submersible is now ready to attempt the country´s first 23,000 feet (7,000 meters) manned dive. The three-man submersible vessel is being carried by the Xiangyanghong 09 ship, which arrived at the designated dive area of the Mariana Trench -- the deepest spot on Earth -- on Monday morning, according to China´s official Xinhua news agency. Depending on local weather and sea conditions, the Jiaolong will dive six times --...

Creatures Of The Abyss Invade Surface World

"Don't panic," Douglas Adams might have said. Author of the sci-fi novel Hitchhiker's Guide to the Galaxy, Adams advised "don't panic" whenever facing invaders. What Adams might not have known is that the inner space of the oceans conceals aliens every bit as resourceful as any that might lurk in outer space. "And now these deep-sea-dwellers have turned the tables on us," says Janet Voight, a biologist at the Field Museum of Natural History in Chicago. Voight and other scientists...

NASA astronaut and commander for the 16th NASA Extreme Environment Mission Operations (NEEMO), Dottie Metcalf-Lindenburger, will be available for live satellite interviews while performing a simulated spacewalk under water. The interviews will take place between 8:45 and 9:45 a.m. EDT June 15. NASA will also host a media day June 21 in Key Largo, Fla. NEEMO sends groups of NASA employees and contractors to live for 12 days, 63 feet below the surface of the Atlantic Ocean, in the National...

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

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...
