GREENBELT, Md., Nov. 22, 2011 /PRNewswire-USNewswire/ -- The Visible Infrared Imager Radiometer Suite (VIIRS) onboard NASA's newest Earth-observing satellite, NPP, acquired its first measurements on Nov. 21, 2011. This high-resolution image is of a broad swath of Eastern North America from Canada's Hudson Bay past Florida to the northern coast of Venezuela. The VIIRS data were processed at the NOAA Satellite Operations Facility (NSOF) in Suitland, Md. (Logo: <font size="2"...

Restoration reduces sea-level rise impacts over next 100 years A new study, led by PRBO Conservation Science (PRBO), projects a bleak future for San Francisco Bay's tidal marshes under high-end sea-level rise scenarios that are increasingly likely. PRBO and colleagues found that in the worst case scenario 93% of San Francisco Bay's tidal marsh could be lost in the next 50-100 years [with 5.4 feet or 1.65 meters of sea-level rise, low sediment availability and no significant restoration]....

Scientists Set Out On New 45-Day Deep-Sea Expedition
2011-11-07 12:43:57

Scientists set out on an expedition to explore the depths of the Indian Ocean on Monday from Cape Town. The researchers will embark on a 45-day research cruise exploring areas where the deepest sea creatures lie. Aurelie Spadone, a sea specialist with the International Union for Conservation of Nature (IUCN) who is among the scientists, said "it would be very surprising if we don't come back with a new species." The mission is the second to visit the seamounts along the South-West...

Operation IceBridge: Watching The Birth Of An Iceberg
2011-11-03 04:41:08

[ Watch the Video ] After discovering an emerging crack that cuts across the floating ice shelf of Pine Island Glacier in Antarctica, NASA's Operation IceBridge has flown a follow-up mission and made the first-ever detailed airborne measurements of a major iceberg calving in progress. NASA's Operation Ice Bridge, the largest airborne survey of Earth's polar ice ever flown, is in the midst of its third field campaign from Punta Arenas, Chile. The six-year mission will yield an...

Swimming Jellyfish May Influence Global Climate
2011-11-02 03:52:29

Swimming jellyfish and other marine animals help mix warm and cold water in the oceans and, by increasing the rate at which heat can travel through the ocean, may influence global climate. The controversial idea was first proposed by researchers out of the California Technical Institute in 2009, but new information may help the scientists support their claim. Dr. Kakani Katija Young, who worked on the original paper, and her team at the Woods Hole Oceanographic Institute published an...

NEEMO Ends Early Due To Hurricane Rina
2011-10-27 05:07:01

NASA said on Wednesday that its 15th NASA Extreme Environment Mission Operations (NEEMO) ended earlier than planned due to Hurricane Rina. The National Oceanic and Atmospheric Administration (NOAA) determined Rina posed a risk to the safety of the mission taking place near Key largo, Florida. The six aquanauts of the NEEMO crew left the facility and returned to the surface of the Florida Keys National Marine Sanctuary on Wednesday. The crew kicked off the mission on October 20 after...

Extreme Melting On Greenland Ice Sheet Reported
2011-10-26 03:32:48

Glacial Melt Cycle Could Become Self-Amplifying, Making it Difficult to Halt The Greenland ice sheet can experience extreme melting even when temperatures don´t hit record highs, according to a new analysis by Dr. Marco Tedesco, assistant professor in the Department of Earth and Atmospheric Sciences at The City College of New York.  His findings suggest that glaciers could undergo a self-amplifying cycle of melting and warming that would be difficult to halt. “We are...

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...
