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!.

New theory of deep-ocean sound waves may aid tsunami detection
Researchers at MIT have now identified a less dramatic though far more pervasive source of acoustic-gravity waves: surface ocean waves, such as those that can be seen from a beach or the deck of a boat. These waves, known as surface-gravity waves, do not travel nearly as fast, far, or deep as acoustic-gravity waves, yet under the right conditions, they can generate the powerful, fast-moving, and low-frequency sound waves.

First evidence that constant stress causes organisms to program changes in offspring
Researchers at The University of Texas at Arlington have now provided the first evidence that stable environments like constant predator threats, not unstable conditions, generate the non-genetic behavioral changes known as 'transgenerational response' in the next generation.

The sponges strike back
Russian biologists studied how the separated sells of marine sponges reconnect. The reaggregation of marine sponges' cells helped the scientists to come closer to understanding of the origin and early evolution of multicellular animals. The work was published in Journal of Experimental Zoology Part A: Ecological Genetics and Physiology.

Survey: Americans would pay more to support biodiversity
Most Americans are willing to pay more taxes each year -- in some cases, as much as $35 to $100 more -- to support biodiversity conservation in the Gulf of Mexico, according to a national survey. Respondents' willingness to help support the proposed expansion of the Flower Garden Banks National Marine Sanctuary near the Texas-Louisiana border reflects growing national awareness of the Gulf's ecological importance and the threats it increasingly faces.

Plankton feces could move plastic pollution to the ocean depths
Plastic waste could find its way deep into the ocean through the feces of plankton, new research from the University of Exeter and Plymouth Marine Laboratory shows.

Undergraduate student takes to Twitter to expose illegal release of alien fish in Japan
Posing a significant threat to the native biodiversity in Japan, specifically that of threatened aquatic insects, some alien fishes, such as the bluegill, have become the reason for strict prohibitions. However, recently, 10 years after the law against their release into the wild has been adopted, its first infringement is reported by Japanese researchers in the open-access journal ZooKeys. Curiously, the case was initially exposed on Twitter by an undergraduate student.

Invasive water frogs too dominant for native species
In the past two decades, water frogs have spread rapidly in Central Europe. Using a new statistical model, researchers from the University of Basel were now able to show that local species such as the Yellow-bellied Toad and the Common Midwife Toad are suffering from the more dominant water frogs. The journal American Naturalist has published their results.

Scientists used high tech ultrasound imaging to study tiger shark reproduction
Researchers from the University of Miami's Rosenstiel School of Marine and Atmospheric Science and the University of New England used the same ultrasound imaging technology used by medical professionals on pregnant women to study the reproductive biology of female tiger sharks. The study offers marine biologists a new technique to investigate the reproductive organs and determine the presence of embryos in sharks without having to sacrifice the animal first, which was commonly done in the past.

Fishing meets science with waders and smartphones
Dutch and American researchers have developed waders equipped with temperature sensors that enable fly-fishers to find the best fishing locations while collecting data to help scientists study streams. The research is published Feb. 29 in Geoscientific Instrumentation, Methods and Data Systems, an open-access journal of the European Geosciences Union.
