What is Causing Sea Star Wasting Syndrome?

What is causing the outbreak?

Original article by Naomi Klouda of the Homer Tribune here

Scientists studying the most recent outbreak of sea star wasting syndrome along the Pacific west coast have ruled out plastics, ocean acidification and radioactivity sourced from Fukushima as likely causes of the die off.  Scientists working on the problem include Pete Raimondi of the Department of Ecology and Evolutionary Biology at University of California, Santa Cruz, and Benjamin Miner, professor of marine biology at Western Washington University, who discussed their most recent work in a National Public Radio Forum. A link to the most up to date map showing the geographic extent of the outbreak can be viewed by clicking here.  The most likely cause appears to be a pathogen/infection that is transmitted through the water and distributed by currents up and down the coast. At present there is no definitive answer as to the cause of the outbreak.

 

Citizen Scientists Should Get Involved

If you are interested in helping the scientific community document the presence of sea star wasting syndrome please visit the following University of California Santa Cruz website.  Another great resource to learn more about the outbreak can be found on Karyn Traphagen’s website that provides fine photos and information.
