The West Coast Ocean Acidification Center held its biennial meeting at the Center for Urban Horticulture today.

Here’s the agenda: Symposium 2019 Draft 4.docx

Here’s the abstracts: WOAC 2019 abstracts.docx

Here’s the poster I presented after Paul’s: CrabMetab_Poster_Final.jpg

Here’s the talk I presented: WOAC2019_STrigg_metab.pptx

Some interesting points were:

Simone Alin’s work showing the 2015 blob year actually had “good” conditions while 2017 had “poor” conditions - this manuscript is in prep

Micah Horwith’s DNR work on oyster (gigas and oly) and clam (manila and geoduck) sea grass outplants showed varying results: - variation between sites, but overall consistent: - positive growth for oysters - no effect for geoduck - negative effect for manila clams - perhaps due to clams burying while oysters stay on the surface? - sea grass does not generate more CO2 at night because of biomass accumulation, fixation, and sluffing

Julie Keister and Evelyn Lessard are finding different microbial community composition associated with different seasons, regions, and seawater chemistry from their cruise surveys (diatoms dominate, high in the spring, decline in the fall; dinoflag. high in the summer; noctiluca and ciliates in the spring and summer) - also check out Vera Trainer’s plankton studies about microbe toxicity/physiology changing with CO2 (ORHAB)

Check out:

  • LiveOcean app to see how winds, upwelling/downwelling, and fresh water input impact seawater current

  • Nanoos climatology app to see chlorophyll and when algae populations are more or less present

Nina Bednarsek’s paper on pteropod mortality and OA - she’s also seeing dissolution of carapace in Dungeness crab megalopae by SEM (not published yet) - would be interesting to look at metabolomics data in light of this

Thoughts from meeting

  • Everyone is very interested in community reponse in the field but not sure the best way to study it
  • Everyone is also very interested in trans-generational effects and if adaptation seems possible
