Stevens uses machine learning-driven techniques to develop a long-awaited tool that better reveals the health of Earth’s oceans and the impacts of climate change. Researchers at Stevens Institute of Technology have developed a new machine learning-powered platform, known as OC-SMART, that can process ocean color in satellite images 10 times faster than the world’s leading platform. The work, which will be adopted by NASA, is one of the first machine learning-based platforms in ocean color analysis that can process both…

Coastal organisms thrive on floating plastic debris in the “great pacific garbage patch”. Coastal plants and animals have found a new way to survive in the open ocean—by colonizing plastic pollution. A new commentary published Dec. 2 in Nature Communications reports coastal species growing on trash hundreds of miles out to sea in the North Pacific Subtropical Gyre, more commonly known as the “Great Pacific Garbage Patch.” “The issues of plastic go beyond just ingestion and entanglement,” said Linsey Haram,…

For more than a decade space-based radar instruments have been routinely observing ocean surface phenomena including wind, waves, oil slicks, even the eyes of hurricanes. Now – employing the same principle as police speed guns – satellite radar has also begun to enable direct measurements of the speed of the moving ocean surface itself.

The oceans that cover 71% of the Earth’s surface are constantly in motion. Ocean surface currents can lead to strong interaction with wind and wa

Ocean acidity is rising as sea water absorbs more carbon dioxide released into the atmosphere from power plants and automobiles. The higher acidity threatens…

Florida State University oceanographer Kevin Speer has a “new paradigm” for describing how the world’s oceans circulate — and with it he may help reshape…

Oxygen in the atmosphere and ocean rose dramatically about 600 million years ago, coinciding with the first proliferation of animal life. Since then, numerous…

Some 56 million years ago, a massive pulse of carbon dioxide into the atmosphere sent global temperatures soaring. In the oceans, carbonate sediments…

Researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science developed a new method to estimate fish movements using ocean…

Researchers from Fraunhofer IOSB, known as team ‘Arggonauts’, are the only German team to reach the semi-finals of the Shell Ocean Discovery XPRIZE. This…

Scientists have uncovered the ocean conditions that support a massive summertime bloom of algae that spans 16 percent of the global ocean. Known as the Great…

Bigelow Laboratory for Ocean Sciences researchers have developed a statistical method to quantify important ocean measurements from satellite data, publishing…

In the course of the past 40 years, the major wind-driven current systems in the ocean have steadily shifted toward the poles. Experts at the Alfred Wegener…

Surviving corals from past underwater heatwaves may be more tolerant of rising ocean temperatures, providing hope for conservation and restoration of reefs. Some coral communities are becoming more heat tolerant as ocean temperatures rise, offering hope for corals in a changing climate. After a series of marine heatwaves hit the Phoenix Islands Protected Area (PIPA) in the central Pacific Ocean, a new study finds the impact of heat stress on the coral communities lessened over time. While a 2002-2003 heatwave devastated coral…

Researchers find that most coralline algae are negatively affected by ocean acidification, but some species may be more resilient than others. Scientists have long suspected that coralline algae are particularly sensitive to changes in ocean chemistry. Now, researchers have found that most species of coralline algae studied are negatively affected by ocean acidification. In a new study published in Global Change Biology, an international team, including researchers from the University of Tsukuba, revealed that lower seawater pH is associated with…

The Arctic Ocean has been getting warmer since the beginning of the 20th century – decades earlier than records suggest – due to warmer water flowing into the delicate polar ecosystem from the Atlantic Ocean. An international group of researchers reconstructed the recent history of ocean warming at the gateway to the Arctic Ocean in a region called the Fram Strait, between Greenland and Svalbard. Using the chemical signatures found in marine microorganisms, the researchers found that the Arctic Ocean…

MBARI’s autonomous technology uses eDNA to survey biodiversity. In a major step forward for monitoring the biodiversity of marine systems, a new study published today in Environmental DNA details how MBARI researchers are using autonomous underwater robots to sample environmental DNA (eDNA). eDNA allows scientists to detect the presence of aquatic species from the tiny bits of genetic material they leave behind. This DNA soup offers clues about biodiversity changes in sensitive areas, the presence of rare or endangered species,…
