Scientists used DNA analysis to explore genetic correlation among Japanese coral population.
The Isthmus of Panama formed three million years, scientists have found out. This contradicts recent studies that pushed this date back to millions of years before. The Isthmus of Panama – the narrow stretch of land lying between the Caribbean Sea and the Pacific Ocean and linking North and South America – has long fascinated scientists.
To see how much the population has changed over the years, Breitburg and other biologists and archaeologists undertook the largest survey to date of any shellfishery, chronicling the Chesapeake Bay's oyster population from almost 800,000 years ago to the present day. The researchers were surprised to find thousands of years during which oyster populations stayed stable – the era of Native Americans.
Researchers who analyzed a history of tsunamis along the Pacific coast of Japan's Tohoku region have learned that seawalls higher than 5 meters reduce damage and death, while coastal forests also play an important role in protecting the public.
Batches of sand from a beach on the Delaware Bay are yielding insights into the powerful impact of temperature rise and evaporation along the shore that are in turn challenging long-held assumptions about what causes beach salinity to fluctuate in coastal zones that support a rich network of sea creatures and plants.
A new study provides the first high-resolution map of the freshwater flow along coastlines in the continental United States, revealing pollution “hot spots.” The study finds that 12% of the U.S. coastline is particularly vulnerable to contamination, including parts of the northern Gulf Coast, the Pacific Northwest, and the northern Atlantic coast, where high rates of seepage overlap areas of human development.
E/V Nautilus team find likely sea slug 5,000ft below sea off Santa Barbara. Analysis reveals foot and proboscis, making it ‘a gastropod of some kind’
Climate change and El Niño the culprits, says Norm Duke, an expert in mangrove ecology, after seeing 7,000ha of dead mangroves over 700km
If your knowledge of New York’s wildlife is limited to pigeons and squirrels, Howard Rosenbaum, the director of the Ocean Giants program at the New York Aquarium in Coney Island, Brooklyn, has some surprising news. “In less distance out to sea than the average New Yorker’s commute home,” he said, “there is likely a whale singing at this very moment.”
In snowy places across the globe, “watermelon snow” forms as the summer sun heats up and melts winter’s leftovers. The colorful snow is made up of communities of algae that thrive in freezing temperatures and liquid water, resulting in algal blooms.
