Since 2014 a small group of environmentalists has been using satellites to track fishing vessels across the world’s oceans, alerting authorities when boats appear to violate protected marine areas. Now these watchdogs are opening their system to the public with an online mapping tool calledGlobal Fishing Watch—and they are inviting anyone who can to put eyes on rogue fishers. Actor Leonardo DiCaprio, a longtime environmental activist, was set to formally unveil the tool on Thursday at a conference in Washington, D.C., organized by the U.S. State Department.
The Arctic’s ice cover appears to have reached its minimum extent on September 10, 2016, according to scientists at the National Snow and Ice Data Center (NSIDC). Arctic sea ice extent on that day stood at 4.14 million square kilometers (1.60 million square miles), statistically tied at second lowest in the satellite record with the 2007 minimum. The 2007 minimum occurred on September 18 of that year, when Arctic sea ice extent stood at 4.15 million square kilometers (1.60 million square miles).
While climate change threatens coral reefs in oceans around the world, not all reefs are affected equally. As oceans warm, physical forces like wave strength and water flow influence which reefs thrive and which die, according to a study led by Justin Rogers, a postdoctoral researcher at Stanford’s Environmental Fluid Mechanics Laboratory.
Last week, I heard a talk where the speaker made statements similar to those I say when talking about COL priorities and the important role the ocean plays in our lives. Things like, “a healthier …
TOS Student Membership Is Now Free!
Nurturing the next generation of scientists is crucially important to the future of oceanography. To support this need, the leadership of The Oceanography Society (TOS) has made membership in The Oceanography Society available free for students enrolled at the graduate or undergraduate level in an oceanography or ocean-related program.

A new analysis of a key contributor to the marine food web has turned up a surprising twist: more unique species in cooler waters than in the tropics, a reversal of the situation on land. The findings highlight the need to direct limited conservation dollars according to science, with a focus on places where biodiversity is most at risk, said Barnabas Daru, Harvard Herbaria Postdoctoral Fellow in Organismic and Evolutionary Biology, who performed the analysis on the world’s 70 species of seagrass.
Every living thing leaves a genetic trail in its wake. As animals, plants and microbes shed cells and produce waste, they drop traces of their DNA everywhere—in the air, soil and water.
Researchers are now able to capture the cells of animals, sequence their DNA and identify which species were present at a point in time. Think of it as genetic fingerprints that leave a trace of past activity.
We mostly can’t see it around us, and too few of us seem to care — but nonetheless, scientists are increasingly convinced that the world is barreling towards what has been called a “sixth mass extinction” event. Simply put, species are going extinct at a rate that far exceeds what you would expect to see naturally, as a result of a major perturbation to the system.
The U.S. government announced Tuesday that it has removed most humpback whales from the federal endangered species list, saying that they have fully recovered in the last 46 years. The move marks “a true ecological success story,” said Eileen Sobeck, National Oceanic and Atmospheric Administration (NOAA) assistant administrator for fisheries in Silver Spring, Maryland, in a 6 September statement.
Sharks have a big reputation for their teeth. The ocean predators use their buzz saw mouths to efficiently dismantle prey, ranging from marine mammals and sea turtles to seabirds and—as Hollywood likes to remind us—an occasional human.
In a first-of-its-kind study, researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science and the ARC Centre of Excellence for Coral Reef Studies at James Cook University showed that increased carbon dioxide concentrations alters brain chemistry that may lead to neurological impairment in some fish.
