Coastal CTD and Water Chemistry Data from NSF RISE Program

NOAA NCEI Accession 0050194 contains CTD Niskin bottle data from the R/V Wecoma, collected during the NSF Coastal Ocean Processes River Influences on Shelf Ecosystems (RISE) program. The dataset includes discrete water samples for CTD and water chemistry analysis from four cruises off the Oregon and Washington coast. Data were collected from 2004 to 2006 and submitted by principal investigator Barbara Hickey.

Use Cases

• Analyze correlations between CTD-derived salinity/temperature profiles and macronutrient concentrations from bottle samples.
• Model the spatial and temporal influence of the Columbia River plume on shelf ecosystems using georeferenced CTD and chlorophyll data.
• Validate regional ocean models by comparing simulated water column structure with in-situ CTD cast data.
• Investigate seasonal or interannual variability in coastal water chemistry from the 2004-2006 time-series.

Strengths

• Data collected over four dedicated research cruises spanning 2004 to 2006.
• Includes both physical (CTD) and biogeochemical (macronutrients, chlorophyll) measurements from discrete samples.
• Focused on a scientifically significant region for studying river-influenced coastal processes.

Limitations

• Specific row counts, column names, and sample sizes are unknown from the provided metadata.
• Data is temporally stale, with the last update recorded in June 2006.
• Geographic coverage is limited to the coastal region off Oregon and Washington.
