Natural nomads, leatherback turtles opt to stay in place
Endangered leatherback sea turtles are known for their open-ocean migratory nature and nomadic foraging habits -- traveling thousands of miles. But a naturalist and his colleagues have discovered an area along the Mozambique coast that the turtles have made their permanent home, according to a study.

Bioacousticians test passive acoustic monitoring to capture sounds of marine life
Hearing is a vital sense for marine mammals who use it to forage, communicate and navigate. Many of these mammals produce specific vocalizations that can be used to identify the species and track their locations via acoustic monitoring. Traditionally, scientists have used underwater microphones to listen for marine mammals, either on the seafloor or towed behind a boat. But now scientists can use autonomous underwater vehicles, gliders and floats specially equipped with hydrophones, to listen to marine mammals in ways impossible until now.

Shedding light on the origin of the baleen whale
The origin of filter feeding in baleen whales -- the largest animal known to have ever existed -- is now better understood, thanks to research on 'Alfred' the 25- million-year-old fossilized whale skull.

New forecast tool helps ships avoid blue whale hotspots
Scientists have long used satellite tags to track blue whales along the West Coast, learning how the largest animals on the planet find enough small krill to feed on to support their enormous size. Now researchers have combined that trove of tracking data with satellite observations of ocean conditions to develop the first system for predicting locations of blue whales off the West Coast. The system, called WhaleWatch, produces monthly maps of blue whale "hotspots" to alert ships where there may be an increased risk of encountering these endangered whales.

Life and death following Great Barrier Reef bleaching
Scientists have confirmed the largest die-off of corals ever recorded on Australia’s Great Barrier Reef. The worst affected area, a 700 km swath of reefs in the northern region of the Great Barrier Reef has lost an average of 67% of its shallow-water corals in the past 8-9 months. Further south, over the vast central and southern regions of the Great Barrier Reef, the scientists were relieved to find a much lower death toll.

Komodo dragons help researchers understand microbial health in captive animals
A new study is the first to identify similarities in the way in which Komodo dragons and humans and their pets share microbes within closed environments.

Marine incentives programs may replace 'doom and gloom' with hope
Incentives that are designed to enable smarter use of the ocean while also protecting marine ecosystems can and do work, and offer significant hope to help address the multiple environmental threats facing the world’s oceans, researchers conclude in a new analysis.

Lake ecologists see winter as a key scientific frontier
As long as ecologists have studied temperate lakes, the winter has been their off-season. It's difficult, even dangerous, to look under the ice, and they figured plants, animals and algae weren't doing much in the dark and cold anyway. But an international team of 62 scientists looking at more than 100 lakes has concluded that life under the ice is vibrant, complex and surprisingly active. Their findings stand to complicate the understanding of freshwater systems just as climate change is warming lakes around the planet.

Toxic 'marine snow' can sink quickly, persist at ocean depths
A specific neurotoxin can persist and accumulate in “marine snow” formed by the algae Pseudo-nitzschia, and this marine snow can reach significant depths quickly, report investigators.

Marine disease likely to follow Great Barrier Reef coral bleaching
Higher water temperatures in 2016 caused the worst destruction of corals ever recorded on Australia's Great Barrier Reef, report experts. And this may be followed by devastating outbreaks of infectious disease, they say.

Most of a caught fish is discarded
Every year 340,000 tons of usable whitefish by-product are discarded into the sea. But the fisheries industry has now identified ways of halting this practice.

Teenage male whale sharks don’t want to leave home
Researchers have completed a huge photo-identification study to assess the seasonal habits of whale sharks in the tropics. They were surprised to discover that the male juveniles didn't seem to venture too far from home.

Why fish send red signals in the deep blue sea
The colorful world of the coral reef is fascinating -- yet much of the color only comes up when flash photography is used. Now biologists have discovered the many meanings of fluorescence where colors fade.

Ocean acidification accelerates erosion of coral reefs
Scientists studying naturally high carbon dioxide coral reefs in Papua New Guinea found that erosion of essential habitat is accelerated in these highly acidified waters, even as coral growth continues to slow. The new research has important implications for coral reefs around the world as the ocean become more acidic as a result of global change.

First glimpse of important, abundant ocean microbe
A rare microbe that was once thought to be insignificant has turned out to be one of the most abundant single-celled hunters in the ocean, and a team of researchers has captured the first glimpse of these elusive predators.

Deep sea coral in North Atlantic faces threat from climate change
North Atlantic coral populations -- key to supporting a variety of sea life -- are under threat from climate change, a study suggests.

Most species-rich coral reefs are not necessarily protected
Coral reefs throughout the world are under threat. After studying the reefs in Malaysia, a researcher concluded that there is room for improvement in coral reef conservation.

Rockfish siblings shed new light on how offspring diffuse and disperse
A splitnose rockfish's thousands of tiny offspring can stick together in sibling groups from the time they are released into the open ocean until they move to shallower water, research shows.
