  • Arctic National Wildlife Refuge Seismic Surveys Back on Track

    By on • ( 0 )

    The Bureau of Land Management on Friday released a proposal to begin a seismic survey in December that would look for underground signs of oil reserves over more than half a million acres on the east side of the refuge’s coastal plain. The Bureau said it would accept public comments on the plan, which was proposed by an Alaska Native village corporation, for 14 days before deciding whether to issue a permit.

  • The “Sea Monster” That Won’t Go Away–NEP20b, AKA The Blob of Warm Ocean Water

    By on • ( 0 )

    The phenomenon of a patch of abnormally warm water off the west coast of North America gained notoriety in 2014, when the first such “Blob” was spotted and given that name, after the horror movie creature that devoured everything in its path. That first Blob lasted years, from 2013 to 2016. It has been blamed for slicing some forage fish populations in half; starving seabirds; triggering a collapse in cod; shifting tuna as far north as Alaska; pushing whales into the path of crab fishing lines and ships; and allowing exotics, including glowing tropical sea pickles, to arrive in northern waters.

    Scientists from a local nature reserve who examined the waters of the bay said 95% of sea life to the depth of 10 to 15 meters was dead.

  • How Wildfire Smoke May Harm Whales & Dolphins

    Wildfire smoke is made up of a range of gases, including carbon monoxide; nitrogen dioxide; polycyclic aromatic hydrocarbons, or PAHs; and hazardous particulate matter, which has been shown to increase risks of respiratory and cardiovascular illnesses in humans.

    “…many sedentary marine species — including snails, worms, and mussels — are actually being transported in the wrong direction”.

  • Marine Heatwaves to Grow in Intensity

    “We know marine heatwaves are on the rise globally, but policymakers, fisheries experts, aquaculture industries and ecologists need to know how this will play out at regional levels, especially in terms of where they will occur and how much hotter they will be,” said lead author from the ARC Center of Excellence for Climate Extremes Dr. Hakase Hayashida.

  • ‘… Highest mercury and arsenic levels ever recorded in stranded dolphins and whales”

    It’s much harder to track the effects of the tens of thousands of chemicals that are dumped in the ocean every day, through sewage, agricultural runoff, and industrial waste—most of which have unknown effects on wild ecosystems. What we do know is that the bodies of marine animals act like magnets for these toxics, which accumulate in their fat and are amplified up the food chain.

  • A 25% Carbon Dioxide Increase Threatens Gulf of Mexico

    “The overall big picture here is that surface water carbon dioxide levels are indeed increasing in the Gulf of Mexico (except in the central Gulf) and human activities are contributing to this acidification,” says Shamberger. “Also, coastal acidification is occurring faster than open ocean acidification, which is especially troubling for coastal coral reef and shellfish ecosystems that support many important fisheries species.”

  • Mass Die-Offs Continue to Threaten Marine Life

    Balmy temperatures can lead to conditions perfect for the spread of infectious diseases, Sanderson said. When sea ice melts too early in the season, seal pups must enter the water before they are ready to be weaned, leaving them weaker and more vulnerable to disease. Vanishing sea ice also means that seals and sea lions in cold regions will have less space to emerge from the water to rest, breed, or escape predators, forcing them to crowd more tightly together.

  • Overfishing Expands

    By on • ( 2 )

    In 2017, 34.2% of the fish stocks of the world’s marine fisheries were classified as overfished, a “continuous increasing trend” since 1974 when it stood at just 10%.
