Bycatch threatens several species of dolphins and porpoises with extinction. To mitigate the effects of accidental catches, Mexican authorities have instated an emergency two-year ban on gillnetting.
Marine animals are altering their diets and natural habitat range as a result of climate change. For instance, melting sea ice is opening new waters to humpback and fin whales, which could lead to increased food competition among the areas' native species.
A citizen-science project is transcribing whaling ships' logs from the mid-1800s in order to add to the environmental history of the Arctic. Want to help, while looking at pages scanned from logbooks held till now in New England libraries and institutions?
Whales are adversely impacted by the sounds ships make under the water. The combination of a vehicle's speed and its propeller count play a large role in noise disturbance.
Dolly Varden, an Alaskan trout species, are able to retire from migrating each year after growing big enough to store and utilize fat reserves. This is the only known species that partakes in such a retirement.
A large stain that is spreading in one part of Lake Erie may have its source in a 1937 shipwreck's fuel load. The Coast Guard and others are investigating.
What's causing the mortality spike of right whales, particularly the very young? Until now, scientists were unsure what was causing such a spike in mortality, but a recent NOAA analysis suggests toxic algal blooms may be to blame.
Beaver dams are helping restore natural ecosystems throughout the U.S. Essentially, a beaver dam blocks off water in one section of the stream, which then creates a pond or lake. Using this, researchers may have found a way to remove excess nitrogen from local estuaries.
Along with micro-beads, we've talked about commercial sunscreens and their effect on marine life. A recent study found that a chemical ingredient found in most sunscreens and roughly 3,500 products is killing young coral.
While parcels of ocean have recently been preserved, researchers from Oregon State University say that the proportion of marine preservation is still far behind that for land. They've laid out reasons why it's much cheaper to act now.
A NOAA research ship recently reported the first humpback whale of the season near one of the Hawaiian Islands. The whales that winter in Hawaii are one of three groups of migrating humpbacks in the northern Pacific Ocean.
It's official, our oceans are experiencing a coral bleaching event on a global scale. According to the National Oceanic and Atmospheric Administration (NOAA), countless simultaneous reef bleaching incidents culminated in to one massive and connected event, formally declared the third global bleaching event ever recorded.
Toxic stormwater has been linked to the death of coho salmon along the U.S. West Coast. Now, using a simply filtration system, researchers may be able to save them from extinction.
After making the most comprehensive study of fish species in the Salish Sea (the body of water that includes Puget Sound and the Strait of Georgia, University of Washington researchers have reported that species diversity there has increased 14 percent.
A newly launched search in Mexico's Sea of Cortez has reportedly found several vaquita marina porpoises, one of the most critically endangered animals in the world. This reassures conservationists that the vaquita isn't extinct yet. However, that doesn't mean the tiny animals are in good shape.
