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.

Governments at every level have taken steps over the last decade to reduce the flow of plastic pollution into the world’s oceans, according to a recently published 91ÉçÇø¸£Àû policy analysis. The analysis finds, however, that the vast majority of new policies have focused specifically on plastic shopping bags.

Reusing low-saline oilfield water mixed with surface water to irrigate farms in the Cawelo Water District of California does not pose major health risks, as some opponents of the practice have feared, a study led by 91ÉçÇø¸£Àû and RTI International researchers finds.

A new $2.44 million grant from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) will support a 91ÉçÇø¸£Àû-led initiative to help utilities and wholesale electricity markets improve their efficiency and reliability while reducing emissions and costs, at a time of needed transformations to tackle climate change.

The Migratory Connectivity in the Ocean (MiCO) system, an online open-access global database that maps the movements of sea turtles, whales, sea birds and other migratory species through the open ocean, has been awarded the 2020 Innovation Award by the Ocean Awards program.

To devise effective and equitable policies for governing small-scale fisheries, policymakers need to consider the activities and relationships that occur before and after fishers land their catches, not just the catches themselves, a new study shows.

A Duke Ph.D. candidate in marine science and conservation uses drones to measure whales and other marine mammals.

Tanker traffic through the Strait of Hormuz can decline for up to two years after a piracy attack, a new 91ÉçÇø¸£Àû study finds, but the adverse effects of the slowdown are far greater on some Persian Gulf countries than others.

Scholars across Duke are working on the complex regulations governing the use of the ocean, and studying the impact of industry on its teeming diversity of life.

The ratio of carbon isotopes in three common species of tuna has changed substantially since 2000, suggesting major shifts are taking place in phytoplankton populations that form the base of the ocean’s food web, a new international study finds.

Inhaling dust that contains fly ash particles from coal combustion has been linked to lung and heart disease, cancer, nervous system disorders and other ill effects. But tracking the presence of coal ash in dust has been a challenge for scientists.

The ongoing transition from coal to natural gas and renewables in the U.S. electricity sector is dramatically reducing the industry’s water use, a new 91ÉçÇø¸£Àû study finds.
