This would allow the structures to self-monitor damaging conditions that could lead to costly repairs, and could also gauge impacts to marine mammals.
The overfishing of codfish spanning the second half of the 20th century indicates that human action can force evolutionary changes more quickly than widely believed, according to a Rutgers-led study. Published in the Philosophical Transactions of the Royal Society B: Biological Sciences, a report by scientists offers the first genomic evidence that Atlantic cod evolved new traits over only decades during a period of overfishing – evolutionary changes that scientists formerly believed could take millions of years.
The marine ecosystems of the South Atlantic Ocean have experienced a significant decline in recent decades due to overfishing and habitat degradation.
Polar fish experience lower mortality than tropical fish, allowing them to delay reproduction until later in life when they are larger and can produce more eggs, according to a study by Mariana Álvarez-Noriega at Monash University in Australia and colleagues, publishing May 25th in the open access journal PLOS Biology.
Animals using the most of efficient methods of searching for resources may well pay with their lives, scientists at the University of Bristol have discovered.
Scientists have been worried about the potential harms of microplastics for years. These small plastic particles less than 5 mm in length have been found everywhere because of plastic pollution – from the Earth’s deep oceans to remote regions in Antarctica, and even the seafood we eat.
Species known as marine habitat-forming species —gorgonians, corals, algae, seaweeds, marine phanerogams, etc.— are organisms that help generate and structure the underwater landscapes.

New research, published in Sciences Advances, has discovered a Chlamydia-like bacteria in corals of the Great Barrier Reef that could help scientists understand the coral microbiome and its potential impact on coral reef health.
The Greenland ice sheet (GIS) and Antarctic ice sheet (AIS) contribute largely to global mean sea level (GMSL) changes, though the seas surrounding the Antarctic like the Bellinghausen-Amundsen Seas and the Indian Ocean sector are seeing significantly more warming than the rest of the marginal seas, with immediate noticeable effects on the mass balance (net weight of the glacier mainly accounting for ice gained by snow and lost by melting and calving) of the AIS.
Florida State University researchers have analyzed the carbon exported from surface waters of the California Current Ecosystem — the first-ever study to quantify the total carbon sequestration for a region of the ocean.
Since in modern agricultural systems, large amounts of pesticides are applied to specific purposes such as weeding and insecticide, and most pesticides are eventually entering the ocean, however, the toxic effects of pesticides on marine microes are unlear.
Little is known about the ecological relationship of Vibrio bacteria with Sargassum. Evidence also is sparse as to whether vibrios colonizing plastic marine debris and Sargassum could potentially infect humans. As summer kicks off and efforts are underway to find solutions to repurpose Sargassum, could these substrates pose a triple threat to public health? Results of a study representing the first Vibrio spp. genome assembled from plastic finds Vibrio pathogens have the unique ability to “stick” to microplastics, harboring potent opportunistic pathogens.
For the first time, a newly published artificial intelligence (AI) algorithm is allowing researchers to quickly and accurately estimate coastal fish stocks without ever entering the water.

This study is designed to shed light on the possible fate of 1.1 million gallons of radioactive wastewater from the Pilgrim Nuclear Power Station, which the plant’s owner, Holtec, has proposed to release into Cape Cod Bay.
An international research team led by Faviel A. López-Romero of the University of Vienna investigated how the jaw shape of sharks has changed over the course of evolution. Their conclusion: in the most widespread shark species, the jaws show relatively little variation in shape over millions of years; most variable jaws were found for deep-sea sharks. The results of this study were published in the journal Communications Biology.
The Woods Hole Oceanographic Institution (WHOI) is assuming management of the Oleander Project, a 30-year effort to monitor circulation in the Northwest Atlantic Ocean using data gathered from sensors mounted on or launched from a cargo ship that makes regular crossings of the Gulf Stream. Magdalena Andres, an associate scientist in WHOI’s Department of Physical Oceanography will head the effort, which began in 1992 under the leadership of H.

Inspired by clam fishermen reports, researchers used passive acoustic telemetry to gauge the interactions between two highly mobile rays. They monitored the tagged rays in the wild over two years to see how often and when they visited clam leases. Results provide both good news and bad news for clammers. Rays spent even more time in these clam lease sites than clammers reported or suspected, but it’s not necessarily where they prefer hanging out.
In a new study they propose that ancestors of Prochlorococcus acquired an ability to latch onto chitin — the degraded particles of ancient exoskeletons. The microbes hitched a ride on passing flakes, using the particles as rafts to venture further out to sea. These chitin rafts may have also provided essential nutrients, fueling and sustaining the microbes along their journey.
Scalloped hammerhead sharks hold their breath to keep their bodies warm during deep dives into cold water where they hunt prey such as deep sea squids. This discovery, published today in Science by University of Hawai‘i at Mānoa researchers, provides important new insights into the physiology and ecology of a species that serves as an important link between the deep and shallow water habitats.
A University of Queensland study has found humpback whales sing louder when the wind is noisy, but don’t have the same reaction to boat engines. Research lead Dr Elisa Girola from UQ’s Faculty of Science said this quirk of whale evolution could have consequences for breeding and behaviour.
A team of marine scientists has examined life cycles, abundance, and seasonal variability of shelled sea butterflies in the north-east Scotia Sea, a region undergoing some of the fastest climate change in the Southern Ocean.
At the 184th ASA Meeting, Colin Malloy of Ocean Network Canada will present his method to transform ocean data into captivating, solo percussion songs. He employs sound from hydrophones and introduces elements inspired by ocean-related data such as temperature, acidity, and oxygenation. For example, in his piece, Oil & Water, Malloy represents the impact of oil production on the oceans. He plays an eerily catchy melody on steel drums and inserts noise to represent oil production over the past 120 years.
