Coastal Bacteria Abundance from Flow Cytometry, Oregon/California 2001-2003

13 ship cruises collected samples from five cross-shelf sections off Oregon and California between 2001 and 2003. Flow cytometry was used to determine abundances of total bacteria, cells with high and low nucleic acid content, Synechococcus, and photosynthetic eukaryotes. The dataset also includes supporting ancillary nutrient and pigment data from bottle casts at six depths, focusing on the upper 100 meters.

Use Cases

• Modeling coastal microbial biomass distribution based on total bacteria abundance data.
• Analyzing the relationship between nutrient levels and bacterial community composition based on ancillary nutrient data.
• Studying phytoplankton-bacteria interactions based on Synechococcus and photosynthetic eukaryote counts.
• Investigating spatial and temporal variability in bacterial nucleic acid content across shelf sections.

Strengths

• Data collected from 13 distinct ship cruises, providing temporal coverage.
• Samples taken from five cross-shelf sections spanning latitudes from 41.9°N to 44.7°N.
• Includes multiple biological variables (e.g., bacteria types, Synechococcus) alongside ancillary nutrient and pigment data.

Limitations

• Last updated 2003-12-31 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description notes not all cross-shelf sections were sampled equally in time and space, indicating potential sampling bias.
