Climate change sea level rises could increase risk for more devastating tsunamis worldwide

Wed, 15 Aug 2018 14:14:44 EDT ~ The threat of rising sea levels to coastal cities and communities throughout the world is well known, but new findings show the likely increase of flooding farther inland from tsunamis following earthquakes. Find out more...

When viruses infect phytoplankton, it can change the clouds

Wed, 15 Aug 2018 13:05:36 EDT ~ Microscopic plant-like organisms called phytoplankton support the diversity of life in the ocean. Scientists now report that one species, Emiliania huxleyi, and a virus closely associated with it, might be responsible for changes in cloud properties as well. When infected, E. huxleyi releases its chalky shell into the air, where it acts as an aerosol reflecting sunlight and even affecting cloud creation and movement. Find out more...

Diving robots find Antarctic winter seas exhale surprising amounts of carbon dioxide

Tue, 14 Aug 2018 13:41:47 EDT ~ A new study uses data gathered by floating drones in the Southern Ocean over past winters to learn how much carbon dioxide is transferred by the surrounding seas. Results show that in winter the open water nearest the sea ice surrounding Antarctica releases significantly more carbon dioxide than previously believed. Find out more...

Glacier depth affects plankton blooms off Greenland

Tue, 14 Aug 2018 10:14:38 EDT ~ The unusual timing of highly-productive summer plankton blooms off Greenland indicates a connection between increasing amounts of meltwater and nutrients in these coastal waters. Researchers now show that this connection exists, but is much more complex than widely supposed. Whether increasing meltwater has a positive or negative effect on summertime phytoplankton depends on the depth at which a glacier sits in the ocean. Find out more...

Europe needs coastal adaptation measures to avoid catastrophic flooding by the end of the century

Mon, 13 Aug 2018 12:52:30 EDT ~ Coastal floods could impact up to 3.65 million people every year in Europe by 2100, according to a new study. Find out more...

Melt-rate of West Antarctic Ice Sheet highly sensitive to changes in ocean temperatures

Mon, 13 Aug 2018 11:35:00 EDT ~ Melting of ice shelves in West Antarctica speeds up and slows down in response to changes in deep ocean temperature, and is far more variable than previously thought, according to new research. Find out more...

Scientists trace atmospheric rise in CO2 during deglaciation to deep Pacific Ocean

Mon, 13 Aug 2018 11:33:38 EDT ~ How carbon made it out of the ocean and into the atmosphere has remained one of the most important mysteries of science. A new study, provides some of the most compelling evidence for how it happened -- a 'flushing' of the deep Pacific Ocean caused by the acceleration of water circulation patterns that begin around Antarctica. Find out more...

Sea stars critical to kelp forest resilience

Mon, 13 Aug 2018 10:03:00 EDT ~ A study by a resource and environmental management researcher reveals that sunflower sea stars play a critical role in the resilience of B.C.'s kelp forests, which are among the most productive ecosystems on Earth. Similar to land-based forests, kelp forests provide essential habitat for species and also help remove CO2 from the atmosphere. Find out more...

Ice sheets of the last ice age seeded the ocean with essential nutrient silica

Fri, 10 Aug 2018 09:10:52 EDT ~ New research led by glaciologists and isotope geochemists has found that melting ice sheets provide the surrounding oceans with the essential nutrient silica. Find out more...

Back to the future of climate change

Thu, 09 Aug 2018 12:55:46 EDT ~ Researchers are looking to the geologic past to make future projections about climate change. Their research focuses on the ancient Tethys Ocean (site of the present-day Mediterranean Sea) and provides a benchmark for present and future climate and ocean models. Find out more...
