Using Flow Cytometry, bacteria abundance was determined for samples collected in Oregon/California coastal waters, 2001-2003, GLOBEC, Northeast Pacific Program.

Standard cross shelf/slope sections (max. of 5) were routinely sampled with bottle casts to determine bacteria abundance and concentration of cells with high/low nucleic acid content. Sampling was conducted during 2001-2003 on 13 ship cruises to the study sites. Six depths were sampled focusing on the upper 100m with an emphasis on 0-50 depth zone and the depth of the chlorophyll-a maximum.

Flow Cytometry was used to determine abundances of: total bacteria, cells with high/low nucleic acid content, synechococcus and photosynthetic eukaryotes. Also reported are supporting ancillary nutrient and pigment data.

These cross shelf sections (HH, NH, CR, RR, FM) are roughly equally spaced between 41.9 N to 44.7 N off coastal California/Oregon. Not all sections were sampled equally in time and space.
