Blacktip sharks usually travel in the tens of thousands from North Carolina to Florida. But thanks to climate change, more are staying put. (From National Geographic / By Eric Niiler ) -- The annual migration of blacktip sharks from southern Florida to North Carolina has begun—and researchers who track this amazing ritual say there are seeing only about one-third the usual [...]
(Credit: Pablo Clemente-Colon / National Ice Center) Above Scandinavia, on the Atlantic side of the Arctic Ocean, mackerel, cod, and other fish native to the European coast are migrating through increasingly ice-free waters, heading deeper into the Arctic Basin toward Siberia. . (From Yale Environment 360/ By Cheryl Katz) -- Thousands of miles to the west, [...]
(Credit: British Antarctic Survey) A new study of tiny marine snails called sea butterflies shows the great lengths these animals go to repair damage caused by ocean acidification. The paper, led by researchers at British Antarctic Survey, is published this month in the journal Nature Communications. (From Phys.org) --The ocean absorbs around one [...]
(Credit: NOAA) The warming climate is expected to affect coastal regions worldwide as glaciers and ice sheets melt, raising sea level globally. For the first time, an international team has found evidence of how sea-level rise already is affecting high and low tides in both the Chesapeake and Delaware bays, two large [...]
(Credit: Mario Tama, Getty) Oceans aren't likely to cool any time soon, a new study finds. In fact, 2017 was the warmest year on record in the ocean, according to researchers from the Chinese Academy of Sciences. (From National Geographic/ By Sarah Gibbens) -- Their findings indicate a "long-term warming trend driven by human [...]
Member Highlight: New Study: Industry Conservation Ethic Proves Critical To Gulf Of Maine Lobster Fishery
(Credit: Gulf of Maine Research Institute) A new study, led by scientists at the Gulf of Maine Research Institute and colleagues at the University of Maine and NOAA, demonstrates how conservation practices championed by Maine lobstermen help make the lobster fishery resilient to climate change. (From Phys.org) -- For generations, lobstermen in Maine [...]
(Credit: Laura Cotton) A new international analysis of marine fossils shows that warming of the polar oceans during the Eocene, a greenhouse period that provides a glimpse of Earth's potential future climate, was greater than previously thought. (From Science Daily) -- By studying the chemical composition of fossilized foraminifera, tiny single-celled animals that [...]
(Credit: Jay Johnson/ IDDO) There's a new way to measure the average temperature of the ocean thanks to researchers at Scripps Institution of Oceanography at the University of California San Diego. In an article published in the Jan. 4, 2018, issue of the journal Nature, geoscientist Jeff Severinghaus and colleagues at Scripps Oceanography [...]
(Credit: Karen Koltes) Forty percent of the world's 7.6 billion people live in coastal cities and towns. A team including Smithsonian marine biologists just released 25 years of data about the health of Caribbean coasts from the Caribbean Coastal Marine Productivity Program (CARICOMP). (From Science Daily) -- The study provides new insights into [...]
The melting Antarctic ice stream that is currently adding most to sea-level rise may be more resilient to change than previously recognized. New radar images reveal the mighty Pine Island Glacier (PIG) to be sitting on a rugged rock bed populated by big hills, tall cliffs and deep scour marks.
There are a lot of scientific eyes on west Antarctica right now, for some pretty obvious reasons. The West Antarctic Ice Sheet (WAIS) holds a lot of water – enough to push up sea levels around the world by 3m or so.
Researchers want to enlist surfers, scuba divers and anglers to monitor hard-to-reach areas vulnerable to climate change. Satellites are good at measuring temperatures over vast stretches of ocean, but less accurate at monitoring a particularly important type of marine environment—coastlines. Now help could come from an unlikely source: a water sports “navy” of surfers, anglers, scuba divers and others. A U.K.-led team of researchers has proposed this alliance to help gather coastal climate data in a recent paper in Frontiers in Marine Science.
