New crew member joins the R/V Elakha

February was cold and dry; the seas were calm enough for us to get out for a day cruise and a night cruise out to NH25.

One of our net tows pulled in some algae that may be pseudo-nitzschia, a harmful algae that can produce the neurotoxin, domoic acid. Scientists are working to understand what causes these algae to produce the toxin at some times and not others. High levels of domoic acid can cause amnesiac shellfish poisoning, closing the harvesting of shellfish like Dungeness crab and razor clams.
