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!.

UNH researchers conduct first comprehensive study of NH oyster farming
University of New Hampshire scientists have conducted the first study of oyster farming-nitrogen dynamics in New Hampshire, providing the first solid research on the state's oyster farming industry and the role oyster farms play with nitrogen removal. The research, which was funded in part by the NH Agricultural Experiment Station, contributes to a growing body of research on how oysters affect the nitrogen content of estuaries such as Great Bay.

Oestrogen in birth control pills has a negative impact on fish
A new doctoral thesis from Lund University in Sweden shows that hormones found in birth control pills alter the genes in fish, which can cause changes in their behavior. The thesis also shows that nurse midwives, who are the main prescribers in Sweden, lack information about the environmental impact of hormonal birth control methods, which may affect the advice they provide.

New software to assess the environmental status of marine ecosystems
The new tool is called NEAT, which stands for Nested Environmental status Assessment Tool. 'NEAT allows us to assess the environmental status of European seas in an integrative way,' says Dr. Borja of AZTI in Spain, an expert on marine biodiversity and coordinator of the European research project DEVOTES.

New maps reduce threats to whales, dolphins
A Duke-led team has created highly detailed maps charting the seasonal movements and population densities of 35 species of whales, dolphins and porpoises -- many of them threatened or endangered -- in US Atlantic and Gulf waters. The maps give government agencies and marine managers better tools to protect these highly mobile animals and guide ocean planning, including decisions about the siting of wind energy and oil and gas exploration along US coasts.

The maximum earthquake magnitude for North Turkey
The Istanbul metropolitan region faces a high probability for a large earthquake in the near future. The question is: how large can such an earthquake be?

Greenland's ice is getting darker, increasing risk of melting
Greenland's snowy surface has been getting darker over the past two decades, absorbing more heat from the sun and increasing snow melt, a new study of satellite data shows. That trend is likely to continue, with the surface's reflectivity, or albedo, decreasing by as much as 10 percent by the end of the century, the study says.

Parasites help brine shrimp cope with arsenic habitat contamination
Do parasites weaken their hosts' resilience to environmental stress? Not always, according to a study published on March 3 in PLOS Pathogens. Rather than weakening its brine shrimp intermediate host, tapeworm infection enhances the shrimps' ability to cope with arsenic contamination in the water -- and the same holds true in the warmer waters predicted by climate change models.

Food limitation linked to record California sea lion pup strandings
Large numbers of California sea lion pups have flooded animal rescue centers in Southern California in the past few years. Now, as part of an ongoing investigation into the Unusual Mortality Event of California sea lions by a team of NOAA scientists and private partners, researchers may have an explanation.

UM researchers found shallow-water corals are not related to their deep-water counterparts
A new study led by scientists at the University of Miami Rosenstiel School of Marine and Atmospheric Science found that shallow-reef corals are more closely related to their shallow-water counterparts over a thousand miles away than they are to deep-water corals on the same reef.

Testing the evolution of resistance by experiment
As scientists look for replacements for our dwindling stock of antibiotics, the evolution of resistance is never far from their minds. Washington University in St. Louis biologist R. Fredrik Inglis explored the ability of bacteria to become resistant to a toxin called a bacteriocin by growing them for many generations in the presence of the toxin.
