Sea Stars - Participate

Contributing to this project involves following a specific observation protocol to count the number of sick sea stars of each species, recording the information on a paper data sheet, and submitting the data through a web interface:

  • Download and print one or more copies of the blank data sheet, depending on the number of transects you might do. (updated 6/17: now just a single sheet for all species)
  • Follow the observation protocol at your beach site, recording your observations on the data sheets. (updated 6/17)
  • Submit observations through the web interface, including information about the location and conditions at the site.

Collected Data

Below are preliminary maps of sea star wasting disease prevalence for Pisaster ochraceus, with sizes greater than 5cm, based on the online-submitted and mail-in intertidal data for May, June, July, and August 2014 (updated 9/2).

  • Animation showing maps of monthly observations for May, June, July, and August.
  • Individual maps of observations for May, June, July, and August.

We have also plotted Ochre Star Intertidal Survivorship from the San Juan Islands, Washington, Summer 2014 (Eisenlord and Harvell).
