A recent paper in the Journal of Physical Oceanography details the specific challenges posed by the many millions of tons of plastic dumped into the ocean every years. The findings indicate that solving the problem may have complicating factors beyond just raw scale (4.8 million to 12.7 million metric tons of dumped in 2015 alone). Read about the research on EurekAlert!.

Video: New Princeton University research proves that ocean currents can move particles like phytoplankton and plastic debris all the way across the world in significantly less time than previously thought. Find out how in this video and on EurekAlert!.

Scientists net virus behind tilapia die-offs in Israel and Ecuador
An international scientific team led by researchers at Columbia University's Mailman School of Public Health and Tel Aviv University has identified and characterized a novel virus behind massive die-offs of farmed tilapia in Israel and Ecuador, which threatens the $7.5 billion global tilapia industry. A paper in the journal mBio describes tilapia lake virus (TiLV) and provides information needed to fight the outbreak.

West Coast scientists sound alarm for changing ocean chemistry
A group of 20 leading ocean scientists has concluded that the ocean chemistry along the West Coast of North America is changing rapidly because of global carbon dioxide emissions, and the governments of Oregon, California, Washington and British Columbia can take actions now to offset and mitigate the effects of these changes.

Common pesticides kill amphibian parasites, study finds
A recent study by Jessica Hua, assistant professor of biological sciences at Binghamton University, and colleagues, explored the effects of six commonly used pesticides on two different populations of a widespread parasite of amphibians. They found that a broad range of insecticides commonly used in the US kill amphibian parasites, which could potentially decrease the number of parasites that amphibians must defend against. For the pyrethroid and neonicotinoid pesticides tested in this study, this pattern has not been documented before.

Earth's internal heat drives rapid ice flow and subglacial melting in Greenland
Greenland's lithosphere has hot depths which originate in its distant geological past and cause Greenland's ice to rapidly flow and melt from below.

UEA research reveals 'topsy turvy' ocean circulation on distant planets
The salt levels of oceans on distant Earth-like planets could have a major effect on their climates. A study published today reveals that the circulation in extremely salty or fresh water extra-terrestrial seas would influence their temperatures -- and could in fact make for more habitable conditions for alien life.

Leading ocean scientists recommend action plan to combat changes to seawater chemistry
A failure to adequately respond to a change in seawater chemistry, known as ocean acidification, is anticipated to have devastating ecological consequences for the West Coast, the 20-member West Coast Ocean Acidification and Hypoxia Science Panel warned in a comprehensive report unveiled Monday, April 4. 'Our work is a catalyst for management actions that can address the impacts of ocean acidification,' said Dr. Alexandria Boehm, co-chair of the Panel and a Professor at Stanford University.

Ice Age Antarctic Ocean gives clue to 'missing' atmospheric carbon dioxide
Syracuse University Earth sciences Assistant Professor Zunli Lu and international collaborators explored the question of carbon dioxide storage in the oceans. The team glimpsed into the ocean's past, thanks to a group of tiny ocean dwellers called foraminifera.

Landscape evolution and hazards
Landscapes are formed by a combination of uplift and erosion. Uplift from plate tectonics raises the land surface; erosion by rivers and landslides wears the land surface back down. In this study, Georgina L. Bennett and colleagues examine the interplay of uplift and erosion along the coast range of Northern California to understand how the modern topography is built.
