Coastal Ocean Nutrient Data from NSF RISE Cruises

Summer 2004 to 2006 data from the NSF CoOP RISE program investigating river discharge impacts on coastal shelf ecosystems. The dataset contains macronutrient and chlorophyll measurements collected during four research cruises aboard the R/V WECOMA in the North Pacific Ocean. It is managed by the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing seasonal and interannual variability of macronutrients (e.g., nitrate, phosphate) in coastal waters.
• Correlating chlorophyll-a concentrations with river discharge events to study phytoplankton blooms.
• Modeling the spatial and temporal impact of large rivers on shelf ecosystem productivity.

Strengths

• Data collection spans three field seasons with four dedicated research cruises, providing temporal depth.
• Focus on a specific, process-oriented research question (river influence on shelf ecosystems) ensures thematic consistency.

Limitations

• Specific column names, row counts, and file sizes are not provided by any source, limiting technical assessment.
• Conflicting 'last updated' dates exist between platforms (2006-06 13 vs. 2026-03-05), indicating potential metadata inconsistency.
