NSF Awards $232K to Study Environmental Impacts on Ancient Maya Port

April 20, 2016

Proyecto Costa Escondida (or Hidden Coast Project), co-led by researchers at CISA3, is an investigation of environmental and ecological factors that affected ancient Maya ports in a network of trade routes linking people, goods and ideas from across Mesoamerica. 

Pollutants in Fish Inhibit Human’s Natural Defense System

April 15, 2016

In a new study, environmental pollutants found in fish were shown to obstruct the human body’s natural defense system to expel harmful toxins. The Scripps Institution of Oceanography at UC San Diego-led research team suggests that this information should be used to better assess the human health risks from eating contaminated seafood. The study was published in the April 15 issue of the journal Science Advances.

Ocean Scientists Recommend Plan to Combat Changes to Seawater Chemistry

April 6, 2016

Global carbon dioxide emissions are triggering permanent changes to ocean chemistry along the North American West Coast that require immediate, decisive action to combat. That action includes development of a coordinated regional management strategy, concluded a panel of scientific experts including Andrew Dickson, a professor of marine chemistry at Scripps Institution of Oceanography at UC San Diego.

What Elephant Seals Can Tell Us About Using Carbon Monoxide to Heal

April 4, 2016

In a new study, most marine mammals were found to exhale carbon monoxide at levels equivalent to or greater than the amount exhaled by a several-packs-a-day smoker.

Climate Change at the Crossroads

March 31, 2016

The Climate Change at the Crossroads series salutes renowned climate scientists at the UC San Diego’s Scripps Institution of Oceanography with three events that will shed light on different facets of climate change.

New Study Shows Desert Mangroves Are Major Source of Carbon Storage

March 28, 2016

A new study led by researchers at Scripps Institution of Oceanography at UC San Diego estimates that coastal desert mangroves, which only account for one percent of the land area, store nearly 30 percent of the region’s belowground carbon.

Biologists Discover Sophisticated “Alarm” Signals in Honey Bees

March 25, 2016

Biologists at UC San Diego and in China found that an Asian species of honey bee can produce different types of vibrational “stop signals” when attacked by giant Asian hornets.

Study: Climate Change Will Reduce the Amount of Saharan Dust in Atmosphere

March 22, 2016

Winds transport dust from the Sahara Desert around the world and influence weather and ecology as far away as the Caribbean and South America. Now a history of this transported dust led by researchers at Scripps Institution of Oceanography at UC San Diego reveals how climate change may alter its global-scale role.

Monarch Butterflies at Risk of Extinction Unless Numbers Increase

March 21, 2016

Long-term declines in the overwintering eastern population of North American monarch butterflies are significantly increasing their likelihood of becoming extinct over the next two decades, according to Scripps Institution of Oceanography at UC San Diego and U.S. Geological Survey research published today.

Upside-Down “Rivers” Threaten Antarctic Ice Shelves

March 14, 2016

) “Upside-down rivers” of warm ocean water threaten the stability of floating ice shelves in Antarctica, according to a new study led by researchers at the University of Colorado Boulder’s National Snow and Ice Data Center and co-authored by researchers at Scripps Institution of Oceanography at UC San Diego. Scripps researchers used satellite laser altimetry to provide a first look at basal channels.
