  1. Not even a Half-baked Talk Murray Levine The Importance of Baseline Samples in CMOP Research: Current Projects and Future Needs

  2. What is the Baseline? • Baseline sample set (53 samples) • Coastal lines NH, CR, LP (36 samples) • Plume (12 samples) • Estuary salinity gradient (5 samples) La Push line Salt gradient Plume Columbia River line Newport Hydroline

  3. Cruises Campaigns Aug./Sept. (17 & 14) September (18) August (18 & 14) November (18) July (18 & 14) May/June (10) May (18 & 14) April (8) April (3) 2010 2009 2008 2007 Past cruises… May/June (14) Jul/Aug (?) Apr (4) Apr (4) Oct (3) 2011 Modified from original by Byron Crump

  4. Future cruises… Spring (4) Spring (4) Spring (4) Fall (3) Fall (3) Fall (3) Fall (3) 2013 2014 2015 2012 ?

  5. What observations (samples) needed for baseline? CTD – with DO, N, trans, Chl fluor Water samples at several depths:

  6. Issues for discussion: • Interrupt time series after 3 years? • Minimal sampling to keep series going? Useful? • Given our experience… • new ideas, • constraints, • opportunities (e.g., Joint Genome Institute proposal)

  7. One way to address the question of baseline relevance… look at current research as measured by manuscripts in preparation

  8. Seasonal variation in protist assemblages of the Columbia River • coastal margin assessed using morphology and 18S rRNA gene sequences • Peter Kahn, LydieHerfort, Tawnya D. Peterson, Lee Ann McCue, Peter Zuber • 2. Oxygen Depletion: Two-Way Shelf-Estuary Linkages In The Coastal Margin • Of A Large River • Antonio Baptista, Charles Seaton • 3. Myrionectarubra bloom initiation in the Columbia River estuary • LydieHerfort, Tawnya Peterson, Victoria Campbell, • SheedraFutrell and Peter Zuber • Submitted to Estuarine Coastal and Shelf Science • 4. Study of bloom formation and retention of Myrionectarubra • in the Columbia River estuary using a Lagrangian modeling approach • Scott Durski, Yvette Spitz, Antonio Baptista, Joe Cho
