  • Ocean Acidification Impacting Southern Oceans

    “We were alarmed to find that diatoms were so negatively affected, with some species likely to have diminished silica production before the end of this century,” says Dr Petrou.

  • Underwater Sound System with Hopes of Reducing Whale Injury from Ships

    A listening station on the channel floor is able to capture whale calls as far away as 30 miles (48 kilometers), the Los Angeles Times reported Friday. That device is connected by cable to a buoy floating above that transmits data by satellite to scientists on shore.

  • 193 Gray Whales Found Dead

    So far, the cause of the die-offs remains a mystery, though theories include starvation from lack of food, or a disease that mimics chronic wasting disease. Teams of scientists are investigating what the casualties mean for the gray whale population as a whole. But some also fear that the deaths could be part of a larger trend as animals struggle to adapt to climate change. Said Ferguson: The “gray whales are just one piece” to the environmental puzzle.

  • Low Oxygen Levels Impact Marine Invertebrates

    With rising global temperatures already lowering marine oxygen levels – to the point of producing and exacerbating coastal ‘dead zones’ – this could become a serious problem.

    Many marine invertebrates – just like other animals with functional and complex eyes – depend on vision for survival. It helps them find prey, avoid predators, and locate shelter.

  • Australian Waters Eyed by Foreign Fishing Interests

    The report says foreign fishing vessels are looking to Australia after stocks elsewhere have been depleted by overfishing. “Australian waters are now in their sights,” the report author Chris Smyth said.

    “Fishing regulations notionally prohibit the entry of foreign fishing vessels, but this has not stopped the approval of foreign super trawlers to fish in Australian waters.”

  • “Marine animals are disappearing at double the rate of land-based species”

    …marine animals like fish, crabs and lobster are already more likely to be living near the threshold of life-threatening temperatures, and because in the ocean, there are fewer places to hide from extreme heat, said Malin Pinsky, lead author of a new study published Wednesday in the journal Nature.

    “These results are stunning, in part because the impacts of climate change on ocean life were virtually ignored just a decade ago,” said Pinsky, an ocean researcher at Rutgers University. The study took a close look at cold-blooded marine species whose body temperatures are dependent on their surroundings.

  • 30 Dead Gray Whales Along West Coast

      Editor’s note: The consistently disturbing news of marine mammals dying off or stranding in mass appears to be a global event. Gray whales are an iconic species that have survived throughout the centuries, including the great whale hunts of the… Read More ›
