Ocean mammals are at a crossroads, with some species at risk of extinction and others showing signs of recovery, a new study by an international team of researchers shows.

A new $411,000 grant from the U.S. Department of Defense’s Strategic Environmental Research and Development Program (SERDP) is funding a four-year study by 91ÉçÇø¸£Àû researchers to better understand the cumulative effects of human and natural stresses on critically endangered North Atlantic right whales.

Harnessing the power of artificial intelligence, satellites and field observations, Duke researchers have produced new estimates of how much photosynthesis and primary production – key components in the global carbon cycle – are occurring in Earth’s oceans, and how these processes may be changing in response to a changing climate.

New research reveals western North American forests may be less able than eastern forests to regenerate following large-scale diebacks linked to climate change. Over time, this could dramatically alter the continent’s landscape.

Policies that more strongly recognize the value of sustainable seafood as a source of nutrition, not just a source of livelihoods, could strengthen global food security and help take a big bite out of world hunger, a new analysis by an international team of experts shows.

A new paper outlines some of the greatest coastal restoration successes in recent decades and identifies lessons we can learn from them to protect and restore similar environments worldwide.

Researchers have used automatic identification systems (AIS) satellite data and other spatial analysis tools to identify more than 1,000 companies that fish in the high seas—waters that lie outside national jurisdiction where fishing has raised fears about environmental and labor violations.

91ÉçÇø¸£Àû researchers have created a new online resource designed to help local governments, conservation groups, businesses and other stakeholders identify the best technologies to clean up plastic pollution in our oceans or prevent it from getting there in the first place.

Groundwater depletion in parts of the High Plains is so extreme that peak grain production in some states has ended and production is now declining, a new 91ÉçÇø¸£Àû-led study by a team of international scientists finds.

The National Science Foundation has awarded Dana Hunt, associate professor of microbial ecology, a $299,693 grant to support research on how hurricanes and other disturbances shape microbial productivity and function in the oceans.

In 2017, a Cuvier’s beaked whale that had been tagged by a team of 91ÉçÇø¸£Àû marine scientists dove deep into the waters off Cape Hatteras, N.C, and stayed below the surface for 3 hours and 42 minutes before coming up for air – making it the longest whale dive ever recorded.

Acting like high-rise timeshares in the sea, shipwrecks and other artificial reefs can support dense populations of sharks, mackerels, barracudas, jacks and other large migratory marine predators essential to ocean health, according to a new study at 30 sites along the North Carolina coast.

A new study finds that dolphin-viewing tours are more profitable than tours where customers can swim with the animals – a much more disruptive option that can deprive spinner dolphins of rest and inhibit their ability to avoid predators while foraging in nearby waters at night.

Salt marshes, seagrass meadows and other coastal ecosystems are in rapid decline around the world. Restoring them is expensive and often unsuccessful. But an international team of researchers has discovered a way to sharply increase the odds of success by using biodegradable mats.
