A seaweed considered a threat to the healthy growth of coral reefs in Hawaii may possess the ability to produce substances that could one day treat human diseases, a new study led by scientists at Scripps Institution of Oceanography at University of California, San Diego has revealed.

The
first global analysis of carbon stored in seagrasses has revealed a
surprising figure. While a typical terrestrial forest stores about
30,000 metric tons of carbon per square kilometer, most of which is in
the form of wood, coastal seagrasses can account for 83,000 metric tons
of carbon per square kilometer. Their global impact is significant as
well.

Starting
this week, U.S. Navy divers will be part of a multinational effort near
Estonia to help clear the Baltic Sea of underwater mines left over from
as long ago as the First and Second World Wars. At the same time,
physicians are studying these divers and how gas molecules form in
humans who experience long periods deep underwater.

According
to predictions made by climate researchers with the Alfred Wegener
Institute for Polar and Marine Research, the Filchner-Ronne Ice Shelf
fringing the Weddell Sea in Antarctica may start to melt rapidly in this
century and no longer act as a barrier for ice streams draining the
Antarctic Ice Sheet. They claim this finding refutes previous
assumptions that climate change would not affect the Weddell Sea.

An
increase in plastic debris floating in a zone between Hawaii and
California is changing the environment of at least one marine critter,
scientists recently reported. Over the past four decades, the amount of
broken-down plastic has grown significantly in a region dubbed the
"Great Pacific Garbage Patch." Most of the plastic pieces are the size
of a fingernail.

Seeking
out statistical techniques that had not previously been applied to
finding the current rate of sea level rise and the rates of ice sheet
melting, scientists in Canada have developed a new method to distinguish
sea-level fingerprints. The technique relies on the fact that the
historical pattern for each ice sheet is unique and is preserved.

Researchers
at the Virginia Institute of Marine Science are investigating whether
sound waves can be used to determine the size of oil droplets in the
subsea—knowledge that could help guide the use of chemical dispersants
during the cleanup of future spills.

Research
led by scientists at the American Museum of Natural History shows that
ammonites—an extinct type of shelled mollusk that's closely related to
modern-day nautiluses and squids—made homes in the unique environments
surrounding methane seeps in the seaway that once covered America's
Great Plains. These findings show that mobile shelled mollusk stayed put
if conditions were right.

A
panel of experts in Japan recently said that any tsunami unleashed by a
magnitude-9.0 earthquake in the Nankai trough, which runs east of
Japan's main island of Honshu to the southern island of Kyushu, could
top 34 m (112 ft) at its highest. This is a significant elevation of
risk from an earlier forecast in 2003 that put the potential maximum
height of such a tsunami at less than 20 m.

From
an extensive study that grew out of an initial research cruise to the
Gulf of Mexico in October 2010, scientists have published the first
evidence of the impact of the Deepwater Horizon oil spill on deep-sea
corals. The team used underwater vehicles and 2D gas chromatography to
determine precisely the source of the petroleum hydrocarbons they found.
