A groundbreaking study is the first to analyze the relationship between group behaviors, group type, group dynamics, and kinship of beluga whales in 10 locations across the Arctic. Results show that not only do beluga whales regularly interact with close kin, including close maternal kin, they also frequently associate with more distantly related and unrelated individuals. Findings will improve the understanding of why some species are social, how individuals learn from group members and how animal cultures emerge.
New research reveals how winners & losers from climate change can be identified based on their ability to adapt to rising future temperatures.
Microbes found deeper in the ocean are believed to have slow population turnover rates and low amounts of available energy. But microbial communities found deeper in seafloor sediments and around hydrocarbon seepage sites have now been found to have more energy available and a higher population turnover. Deeper sediments in the seepages are most likely heavily impacted by the material coming up from the bottom, which means that the seep could be supporting a larger amount of biomass than previously thought.
Fish kills are a recurring phenomenon in lakes suffering from oxygen depletion. Often the kills are triggered by factors like an algae bloom, but now a new study reports on a new, climate-related cause of fish kills.
As the planet’s land-based natural resources become exhausted, the need for new sources is bringing the search to the deepest parts of the world’s oceans. And that has researchers across the globe very concerned.

Dolphins use unusual techniques to obtain food: One of them, called "shelling", is used by the dolphins in Shark Bay in Western Australia. Dolphins in this population trap fishes inside large empty gastropod shells.
Genetic clues show that eelgrass growing underwater along Puget Sound shorelines is associated with fewer of the single-celled algae that produce harmful toxins in shellfish. The evidence shows this effect extends 45 feet beyond the edge of the eelgrass bed.
Two new genera and four new species of giant, single-celled xenophyophores (protozoans belonging to a group called the foraminifera) were discovered in the deep Pacific Ocean during a joint project between scientists at the National Oceanography Centre, UK (NOC), the University of Hawai'i, and the University of Geneva
The global redistribution of marine and terrestrial species due to climate change is a major concern for conservation planners and resource managers.
In an article published in Nature Ecology & Evolution today (22 June), the leaders of a new global initiative explain how research during this devastating health crisis can inspire innovative strategies for sharing space on this increasingly crowded planet, with benefits for both wildlife and humans.
Sea ice across the Southern Ocean played a crucial role in controlling atmospheric carbon dioxide levels during times of past climate change - and it could provide a critical resource to improve Earth system models, a new study shows.
A new global study has found that only 2.5 percent of tropical reefs are formally protected and conserved through laws and regulations. These numbers are significantly lower than previous estimates, and highlight an urgent need for governments, communities, and partnering organizations to create and expand marine reserves to protect these ecosystems which support more than 500 million people worldwide.
Scientists have discovered that the summer sea ice in the Weddell Sea sector of Antarctica has decreased by one million square kilometres - an area twice the size of Spain - in the last five years, with implications for the marine ecosystem. The findings are published this month (June 2020) in the journal Geophysical Research Letters.
A diverse diet and flexible behaviour may have empowered blenny fish to make a dramatic transition out of the water - but once on land, they have been forced to become specialised, a new study led by UNSW shows.
The most comprehensive health assessment for a green turtle rookery in the world to date is providing critical insights into various aspects of physiology, biology, and herpesvirus epidemiology of this nesting population. Findings are hopeful for this population of green sea turtles in southeastern Florida, offer important data on the profile of health for future comparative investigations, and suggest that viruses are endemically stable in this nesting population.
Research Associate Mr Chim Chee Kong and Research Assistant Ms Samantha Tong from the Tropical Marine Science Institute at the National University of Singapore (NUS) are on a quest to discover the many nameless tanaids in the world, specifically in the relatively species-rich but poorly studied tropical Indo-Pacific.
Many of us have seen informational posters at parks or aquariums specifying how long plastics bags, bottles, and other products last in the environment. They’re a good reminder to not litter, but where does the information on the lifetime expectancy of plastic goods come from, and how reliable is it?
While there was a bay-wide decline of submerged aquatic vegetation (SAV) from the 1960s through the 1980s, restoring these once-abundant SAV beds has been a primary outcome of efforts to reduce loads of nutrients and sediments to the estuary and SAV cover has increased by 300 percent from 1984 to 2015. One of the largest recovered SAV beds lies in an area of the bay known as the Susquehanna Flats—a broad, tidal freshwater region located near the mouth of the Susquehanna River at the head of the bay.
On World Oceans Day, an international team of marine scientists reports that the potential impact of marine renewable energy to marine life is likely small or undetectable, though there is still uncertainty around some issues.
Researchers have projected significant changes in the habitat of commercially important American lobster and sea scallops on the Northeast U.S. continental shelf.
After weeks of preparation, isolation, and testing, a science team will depart on the R/V Neil Armstrong from Woods Hole, MA for an 11-day expedition.
Mangrove trees – valuable coastal ecosystems found in Florida and other warm climates – won’t survive sea-level rise by 2050 if greenhouse gas emissions aren’t reduced, according to a Rutgers co-authored study in the journal Science. Mangrove forests store large amounts of carbon, help protect coastlines and provide habitat for fish and other species. Using sediment data from the last 10,000 years, an international team led by Macquarie University in Australia estimated the chances of mangrove survival based on rates of sea-level rise.
More than 1,000 bottlenose dolphins live in Florida’s Indian River Lagoon year-round. Although extensively studied, what they do at nighttime is still a mystery. Using satellite telemetry, scientists provide the first documentation that these dolphins have a larger range that encompasses more habitats than previously thought. They regularly leave the brackish waters of the estuarine system and, not only travel into the ocean, but swim substantial distances – up to 20 kilometers – up freshwater rivers, creeks, and canals.
Warming ocean temperatures and acidification drastically reduce the skeletal strength and filter-feeding capacity of glass sponges, according to new UBC research.

Of the top five countries in the world most at risk to disasters, three are Pacific Island nations. Yet time and time again, Pacific Islanders exhibit marked abilities to quickly recover. Part of the reason may be due to strong social networks that help to distribute resources to those most in need, say marine scientists from the University of Hawaiʿi, National Geographic Society and WCS (Wildlife Conservation Society) in a new study.
Historical observations collected off California since the 1950s suggest that anchovies thrive where the water is breathable — a combination of the oxygen levels in the water and the species’ oxygen needs, which are affected by temperature. Future projections suggest that the waters off Mexico and Southern California could be uninhabitable by 2100.
On May 20, ocean explorer and world-renowned filmmaker James Cameron will host a special edition of Ocean Encounters, a popular virtual event series from Woods Hole Oceanographic Institution.
Aerial drone footage provides the first evidence of adult blacktip sharks using shallow waters as a refuge from a huge predator – the great hammerhead. Before this study, documentation of adult sharks swimming in shallower waters to avoid predation did not exist. Unmanned aerial vehicles enable scientists to unobtrusively observe behaviors in the wild, providing insight into seldom-seen predator-prey interactions. When it comes to sharks, this “hammerhead” time video proves you “can’t touch this.”
