NOAA scientists and their colleagues have discovered a biological marker in the blood of laboratory zebrafish and marine mammals that shows when they have been repeatedly exposed to low levels of domoic acid, which is potentially toxic at high levels.
(Wiley-Blackwell) Ecologists in New Zealand have shown for the first time that Marine Protected Areas - long advocated as a way of protecting threatened marine mammals - actually work.
Increasing acidification in coastal waters could compromise the ability of oysters and other marine creatures to form and keep their shells, according to a new study led by University of Georgia researchers.

Boninite lavas are erupted during the early stages of subduction, however they have previously been found only in the ancient geological record. Discovery of an active boninite eruption shows that abundant volatile gases derived from the subducting slab drive this violent eruptive activity, even in the deep sea.
Two competing models have been suggested to explain the recovery of ecosystems from mass extinctions. An analysis of the recovery of marine pelagic communities from the Cretaceous–Palaeogene mass extinction supports a model of contingent recovery, rather than one based on trophic structure.
Dr Chris Roelfsema, from the School of Geography, Planning and Environmental Management at UQ, is concerned about the impact the 2011 floods may have on seagrass in Moreton Bay.
In this monograph, author Michael Einsenstadt discusses the strategic culture of Iran and its impact on the country's approach to strategy and war. Through an examination of Iran's “way of war,” Eisenstadt offers specific suggestions for the United States to better engage or deal with Iran.

New research indicates that sharks and marine turtles are in trouble around the globe. Scientists offer some new insights into possible methods for reversing these trends. Pressures on marine environments - from rising sea temperatures and overfishing to pollution and oils spills - is taking an increasingly heavy toll on a variety of marine species including turtles and sharks.
Marine turtles worldwide are vulnerable and endangered, but their long lives and broad distribution make it difficult for scientists to accurately determine the threat level to different populations and devise appropriate conservation strategies.
