By distinguishing between lead from modern sources and lead from pre-1970s vehicle exhaust fumes and leaded paint, the new test may be especially useful for assessing the hidden risks of legacy contamination.

Clouds of smoke and ash from wildfires that ravaged Australia in 2019 and 2020 triggered widespread algal blooms in the Southern Ocean thousands of miles downwind to the east, a new 91��������-led study by an international team of scientists finds.

Warming waters along the Western Antarctic Peninsula have led to declines in the diversity and distribution of the region’s plankton population and its ability to absorb climate-warming carbon dioxide from the atmosphere.

Using drones and artificial intelligence to monitor large colonies of seabirds can be as effective as traditional on-the-ground methods while reducing costs, labor and the risk of human error, a new study finds.

The WildTrack Specialist Group, a global network of biologists and conservationists dedicated to using only non-invasive techniques to monitor and protect endangered species, will be launched April 22 to celebrate Earth Day.

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.

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.

The proliferation of pits and ponds created in recent years by miners digging for small deposits of alluvial gold in Peru’s Amazon has dramatically altered the landscape and increased the risk of mercury exposure for indigenous communities and wildlife, a new study shows.

Interactive software that “reads” and analyzes footprints left by black rhinoceroses can be used to monitor the movements of the animals in the wild, giving conservationists a new way to keep watch on the endangered species and help keep it safe from poachers, according to a 91��������-led study.

Scientists at 91�������� are harnessing the power of big data and geospatial analysis to create new ways to track the effects of climate change on species and food webs.

By providing the first estimate of how much hydrogen is available to fuel microbial life in the sunless sub-seafloor crust beneath the Mid-Ocean Ridge (MOR), a new 91��������-led study sheds light on one of Earth’s least understood biospheres.

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.

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

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.

A new study which combines measurements from nearly 1,400 drinking water wells across North Carolina estimates that more than half of the wells in the state’s central region contain levels of cancer-causing hexavalent chromium in excess of state safety standards.
