BAKU, Nov 19 (IPS) - Mercury pollution from burning coal is contaminating our oceans and seafood, threatening global health.

Researchers on a multimonth Antarctic expedition describe how the climate crisis intertwines with their work.

About 50 years after the Oregon Department of Fish and Wildlife hired its first female field biologist, it will be led by one. The Oregon Fish and Wildlife...

The Sargasso Sea in the Atlantic Ocean is now at least 30% more acidic and 1.8 degrees Fahrenheit warmer than it was 40 years ago — and climate change is to blame.

Radiation in water from Fukushima will be diluted to almost background levels, but some researchers are not sure this will be sufficient to mitigate the risks

A team of graduate students and researchers from the University of Miami is navigating through the northern Atlantic Ocean on an international research voyage to learn more about how the ocean is changing through time.

Planetary Technologies, a Canadian startup, is attempting to use an antacid powder to make the ocean recycle more carbon dioxide from the atmosphere.

The scientific expedition to the Nord Stream leak from the University of Gothenburg has arrived back home. The researchers discovered that the methane levels near the leak were about 1,000 times higher than normal, but it's too early to draw any conclusions from that discovery. The researchers have brought back heaps of samples to analyze.

When smoke from the 2019–2020 Australian wildfires billowed across the Southern Ocean, the iron-rich particles it deposited on the ocean triggered an algae bloom bigger than Australia—and it had a rapid and prolonged impact on the Southern Ocean's marine ecosystem and its carbon cycle.

When Christopher Tubbs joined an ambitious multinational effort to save California condors from the brink of extinction, he knew the odds of success were long.

The ocean's twilight zone is deep, dark, and—according to new research—iron deficient. No sunlight reaches this region 200 to 1,000 meters below the sea surface, where levels of iron, a key micronutrient, are so low that the growth of bacteria is restricted. To compensate, these bacteria produce molecules called siderophores, which help the bacteria scavenge trace amounts of iron from the surrounding seawater.

Radiation in the water will be diluted to almost-background levels, but some researchers are not sure this will be sufficient to mitigate the risks.

When Mauna Loa erupted last month, the lava flow messed with some instruments that measure carbon dioxide, so a scientist tried Haleakalā, a volcano next door, Jack Truesdale writes.

These vents are located off Mexico's western coast.

The hottest and largest hydrothermal vent system was just discovered by scientists after mapping the East Pacific seafloor!

To unravel the effects of melting sea ice, researchers drill the frozen waters around Antarctica and receive a surprise visit from a group of penguins.

A CalTech spinoff uses limestone to tackle carbon dioxide in shipping exhaust. The shipping company Lomar will soon begin testing the process.

President Sally Kornbluth talks with Associate Professor Desirée Plata about her research — and what she wishes students knew about their professors.

A Danish official says the Nord Stream gas leaks in the Baltic Sea could emit the equivalent of one third of Denmark's total annual greenhouse gas emissions.
