NOAA's Center for Operational Oceanographic Products and Services (CO-OPS) has developed an innovative system design to collect water level data in remote cold climate regions where there are problems with ice accumulation. ...

A combination of the biology of marine mammals, mechanical vibrations and acoustics has led to a breakthrough discovery allowing scientists to better understand the potential harmful effects of sound on marine mammals such as whales and dolphins....

Snail mail might be the answer to help federal officials protect US coastal waters from overfishing. Anglers say the feds currently rely on questionable data from a home phone survey to calculate recreational fishing volume and decide which locales to place off limits so stocks can rebuild. A new study found a snail mail survey netted a higher response rate and more complete data, says a statistician....

The world's most established fisheries certifier is failing on its promises as rapidly as it gains prominence, according to leading fisheries experts....

Coral reefs are sensitive to climate change and track sea level. New observations show that an extensive coral reef existed in the southern Pacific Ocean thousands of years ago. Researchers used multi-beam sonar, coring, and dating to examine a relict reef discovered in water about 20-25 meters (65-82 feet) deep around Lord Howe Island in the southern Pacific Ocean....

A tiny marine filter-feeder that anchors itself to the sea bed offers new clues to scientists studying the stability of the West Antarctic Ice Sheet -- a region that is thought to be vulnerable to collapse. Scientists analyzed sea-bed colonies of bryozoans from coastal and deep sea regions around the continent and from further afield. They found striking similarities in particular species of bryozoans living on the continental shelves of two seas -- the Ross and Weddell -- that are around 1,500 miles apart and separated by the West Antarctic Ice Sheet....

A unique 'natural laboratory' in the Mediterranean Sea is revealing the effects of rising carbon dioxide levels on life in the oceans. The results show a bleak future for marine life as ocean acidity rises, and suggest that similar lowering of ocean pH levels may have been responsible for massive extinctions in the past....

Scientists are gaining a deeper understanding of marine mammal travel patterns using a large-scale tracking network. A new Public Library of Science (PLoS) collection, created in conjunction with the Pacific Ocean Shelf Tracking (POST) Program and the Census of Marine Life (CoML), will highlight the variety of ways scientists are using this large POST network to trace marine animal movement in the Northeast Pacific Ocean....

A relatively new type of El Niño, which has its warmest waters in the central-equatorial Pacific Ocean, rather than in the eastern-equatorial Pacific, is becoming more common and progressively stronger, according to a new study by NASA and NOAA. The research may improve our understanding of the relationship between El Niños and climate change, and has potentially significant implications for long-term weather forecasting....
