Sharks are the stewards of coral reef systems. As apex predators, they pick off sick and weak fish, leaving the stronger ones to reproduce, which helps maintain the health and…
Sail 200 nautical miles, or 370 kilometers, from any coastline, and you’ll enter a region called the “high seas,” beyond the control of any country. While many people never get…
Most of the tropical reef sites around the world are no longer able to simultaneously sustain coral reef ecosystems and the livelihoods of the people who depend on them, as…
Canada has announced new protection measures for North Atlantic right whales, which face severe threats to their survival due to human activities off the Atlantic Coast of North America. With…
It’s a beguiling proposition: pulling carbon dioxide out of the atmosphere by supercharging populations of microscopic, carbon-munching marine phytoplankton through the relatively simple and inexpensive process of adding iron to…
In March 2000, U.S. Navy destroyers were conducting routine training exercises in the Bahamas; they swept an underwater canyon with sonar at 265 decibels to uncover the locations of two…
One of just four North Atlantic right whale calves spotted off the southeast coast of the United States so far this winter was discovered last week to have suffered deep…
For seabirds, an Arctic Ocean with less sea ice could provide some tantalizing alternatives to the long-haul flights that some undertake each year. In a recent study, ecologist Manon Clairbaux…
Scientists say that behavioral changes observed in North Atlantic right whales should be considered a “canary in the coal mine” scenario. A team of researchers with the Center for Conservation…
Most of us have places where we feel safe — a tree in our backyard, a den in our house, a beach in our town. But these days, some “safe…
Far out in a featureless sea, the light of the moon is a beacon for migrating eels. They’re aiming for coastal estuaries, gateways to freshwater rivers where they will live…
New research finds that the western South Atlantic humpback population is well on its way to recovering from the devastating impacts of commercial whaling. Whaling took a large toll on…
A scientific expedition launched by environmental NGO Greenpeace has discovered a new humpback breeding ground off the coast of French Guiana and sent the first-ever deep divers down to the…
Bringing the protection of the “Atlantic Galapagos” one step closer to becoming a reality, the Governor of St. Helena, Ascension, and Tristan da Cunha, Philip Rushbrook, designated a large-sale Marine…
With a reported top speed of 74 kilometers per hour (46 miles per hour), the shortfin mako (Isurus oxyrinchus) is one of the fastest creatures in the sea. It can…
New research finds that thousands of sharks and rays could be entangled in the plastic polluting Earth’s oceans. Scientists at the UK’s University of Exeter examined existing scientific literature and…
JAKARTA — The widespread use of wooden fences to trap fish by coastal fishermen in tropical countries is causing extensive economic, social, and environmental damage, according to a new study.…
It’s hard to imagine how the oceans might operate without the sway of human activity. The recent assessment by the U.N. Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services found…
An analysis of 33 years’ worth of data finds that ocean winds and wave heights are becoming more extreme worldwide, with the Southern Ocean seeing the largest increases. In order…
Scientists have fretted over the expanding masses of plastic in the ocean for decades. Most have seen the rise with their own eyes, and yet the available datasets typically don’t…
Research over the past few years has shown that ocean acidification impacts Atlantic cod at the earliest stages of their lives, while they are still eggs and larvae. Scientists hoped…
In a remote spot in the South Atlantic, roughly 1,600 kilometers (1,000 miles) from the coast of West Africa, lies Ascension Island, one of the U.K.’s Overseas Territories. In January…
There’s finally some good news for the troubled North Atlantic right whale, one of the most endangered whale species in the world. After a year when no newborns were confirmed,…
A recent study found microplastics in the intestines of humans around the globe, and new research has now done the same for sea turtles. Researchers at the UK’s University of…
Brazil’s environmental regulatory agency, Ibama, announced last Friday that it was denying French oil company Total license to drill for oil near the Amazon Reef. The reef system, discovered off…
Scientists have mapped whale stress levels in relation to human activity going back nearly a century and a half — using earwax collected from baleen whales. From 1870 to 2016,…
On October 14, the crew of a US National Oceanic and Atmospheric Administration (NOAA) ship called the Henry B. Bigelow reported a whale carcass floating about 100 miles east of…
When Luiz Rocha, a fish biologist at the California Academy of Sciences, goes scuba diving, he tacks on one and a half times his body weight in specialized diving gear.…
Noise from ships changes the way that whales and dolphins communicate with each other, according to two studies published this week. Marine biologists know that an increasingly cacophonous ocean, filled…
In a remote part of the Atlantic Ocean off Brazil, researchers have found a stunning pink-and-white neon-colored fish that’s new to science. Luiz Rocha, an ichthyologist at the California Academy…
