Underwater earthquakes’ sound waves reveal changes in ocean warming

A new technique uses the echoes of earthquakes in seawater to track the impact of climate change on the oceans.

Climate

Bering Sea winter ice shrank to its lowest level in 5,500 years in 2018

Peat cores that record five millennia of climate shifts in the Arctic region suggest recent ice loss is linked to rising carbon dioxide levels.

Species may swim thousands of kilometers to escape ocean heat waves

A new analysis of ocean heat waves shows latitude matters when it comes to how far fish and other sea species must go to find cooler waters.

Predictions for the 2020 Atlantic hurricane season just got worse

Wind patterns and abnormally warm seawater are conspiring to create especially hurricane-friendly conditions in the Atlantic.

Oceans

These ancient seafloor microbes woke up after over 100 million years

Scientists discover that microbes that had lain dormant in the seafloor for millions of years can revive and multiply.

Climate

Rapid sea level rise could drown protective mangrove forests by 2100

Mangroves have kept up with rising water so far, but new research reveals their limits.

Life

Neon colors may help some corals stage a comeback from bleaching

When some corals bleach, they turn bright colors. Stunning hues may be part of a response that helps the corals recover and reunite with their algae.

Deep-sea mining may damage underwater ecosystems for decades

Microbe communities in the seabed off Peru still haven’t fully recovered from being disturbed by a deep-sea mining experiment 26 years ago.

Earth

Forecasters predict a very active 2020 Atlantic hurricane season

Warmer ocean temperatures could fuel a very active Atlantic hurricane season, with one forecast predicting 18 named storms, including nine hurricanes.

Environment

A year long expedition spotlights night life in the Arctic winter

Scientists anchored to an ice floe near the North Pole are investigating how life survives polar night and what changes will occur as the Arctic continues to warm.

Life

The Great Barrier Reef is suffering its most widespread bleaching ever recorded

Major bleaching events are recurring with increasing frequency on the Great Barrier Reef, hindering its recovery.

Animals

Parasitic worm populations are skyrocketing in some fish species used in sushi

Fishes worldwide harbor 283 times the number of Anisakis worms as fishes in the 1970s. Whether that’s a sign of environmental decline or recovery is unclear.
