Spring plankton bloom hitches ride to sea's depths on ocean eddies
(National Science Foundation) Just as crocus and daffodil blossoms signal the start of a warmer season on land, a similar 'greening' event --a massive bloom of microscopic plants, or phytoplankton -- unfolds each spring in the North Atlantic Ocean from Bermuda to the Arctic.

Swirling currents deliver phytoplankton carbon to ocean depths
(Woods Hole Oceanographic Institution) Just as crocus and daffodil blossoms signal renewal and the start of a warmer season on land, a similar 'greening' event -- a massive phytoplankton bloom -- unfolds each spring in the Atlantic Ocean from Bermuda to the Arctic. But, what happens to all that organic material produced in the surface ocean?

Antarctic ice shelves rapidly thinning
(University of California - San Diego) A new study published by Science and led by Scripps Institution of Oceanography at UC San Diego researchers has revealed that the thickness of Antarctica's floating ice shelves has recently decreased by as much as 18 percent in certain areas over nearly two decades, providing new insights on how the Antarctic ice sheet is responding to climate change. Data from nearly two decades of satellite missions have shown that the ice volume decline is accelerating.

Coastal property values could erode if nourishment subsidies end
(Duke University) The value of many oceanfront properties on the East Coast could drop dramatically if Congress were to suddenly end federal beach nourishment subsidies. Values could fall by as much as 17 percent in towns with high property values and almost 34 percent in towns with low property values. A gradual reduction of the subsidies, in contrast, is more likely to smooth the transition to more climate-resilient coastal communities.

A mile deep, ocean fish facing health impacts from human pollution
(Oregon State University) Deep-water marine fish living on the continental slopes at depths from 2,000 feet to one mile have liver pathologies, tumors and other health problems that may be linked to human-caused pollution, one of the first studies of its type has found. The findings appear to reflect general ocean conditions.

Florida Tech study finds climate refuges where corals survive, grow
(Florida Institute of Technology) As rising ocean temperatures continue to fuel the disappearance of reef-building corals, a new study from Florida Tech finds there may be some climate refuges where corals will survive in the future.

Shell-shocked: Ocean acidification likely hampers tiny shell builders in Southern Ocean
(University of Colorado at Boulder) University of Colorado Boulder study shows a ubiquitous type of phytoplankton -- tiny organisms that are the base of the marine food web -- appears to be suffering from the effects of ocean acidification caused by climate change.

NASA-NOAA satellite sees semnants of ex-Tropical Cyclone Nathan
(NASA/Goddard Space Flight Center) NASA-NOAA's Suomi NPP satellite captured an image of the remnants of Tropical Cyclone Nathan over the southern Top End of Australia's Northern Territory on March 25.NASA-NOAA's Suomi NPP satellite captured an image of the remnants of Tropical Cyclone Nathan over the southern Top End of Australia's Northern Territory on March 25.

This week from AGU: Q&A with Rex Buchanan, solar storm satellite, pollution from aquifers
(American Geophysical Union) This week from AGU: a Q&A with Rex Buchanan, solar storm satellite and pollution from aquifers.

NASA sees Nathan weakening near Darwin, Australia
(NASA/Goddard Space Flight Center) Tropical Cyclone Nathan has been weakening as it continued to move over land in Australia's Northern Territory on March 24. NASA's Aqua satellite captured a visible picture of the storm over land. Just one day before the Tropical Rainfall Measuring Mission satellite saw some heavy rainfall in Nathan.
