Wasting disease devastates Alaska sea star populations – “The spread of the disease may be related to the unprecedented warm waters in the Gulf of Alaska in the past two years”

5 May 2017 (UAF) – In one year, sea stars have almost disappeared from Kachemak Bay, Alaska. This is likely the aftermath of a sea star wasting disease episode. The disease causes lesions, and may result in the loss of arms, making a sea star look as if it is melting or decomposing. Similar episodes have been spreading across the southern coast of Alaska and as far south as Baja California. “In spring 2016 we counted 180 sea stars during our intertidal surveys, which was high in the books,” said Brenda Konar, a professor at the University of Alaska Fairbanks College of Fisheries and Ocean Sciences. “Just one year later, we counted only five sea stars.” Konar and CFOS professor Katrin Iken are part of Gulf Watch Alaska, a monitoring program established by the Exxon Valdez Oil Spill Trustee Council to better understand how intertidal and other marine ecosystems were affected by the 1989 oil spill. The intertidal zone is the area between high and low tide. Konar and Iken monitor Kachemak Bay on the Kenai Peninsula near Homer. […] “The spread of the disease to Alaskan waters and its impact on sea star diversity may be related to the unprecedented warm waters that we experienced in the Gulf of Alaska in the past two years,” Iken said.

"Universal suicide is the most logical thing in the world, we reject it only because of our primitive cowardice and childish fear of the dark. If we were sensible we would seek death, the same blissful blank which we enjoyed before we existed. It does not matter what happens to the race in the cosmos, the existence or non-existence of the earth and its miserable inhabitants is a thing of the most complete indifference."
