North Pacific Ocean Water Chemistry from NOAA Ship Oscar Elton Sette

Laboratory analysis of nitrate, nitrite, phosphate, and silicate concentrations in water samples collected along a 158°W transect from 26°N to 36°N in the central North Pacific. The dataset was created by the Oregon State University Chemistry Laboratory for NOAA and spans from March 2008 to March 2011. It is hosted on multiple government data platforms, indicating its established use in the scientific community.

Use Cases

• Analyzing nutrient concentration gradients (nitrate, phosphate, silicate) along a north-south transect.
• Investigating seasonal or interannual variability in ocean chemistry from 2008 to 2011.
• Calibrating or validating satellite-derived ocean color products with in-situ nutrient measurements.
• Studying the relationship between nutrient availability and biological activity in the central North Pacific.

Strengths

• Data originates from a controlled laboratory analysis performed by Oregon State University Chemistry Laboratory.
• Provides a multi-year time series covering a specific geographic transect in the central North Pacific.
• Cross-platform presence on Data.gov and NASA EarthData signals peer-reviewed importance and reliability.

Limitations

• Column names and the exact row count are not provided in any source description.
• Sources conflict on the last updated date, with Data.gov showing 2026 (likely a metadata error) and NASA EarthData showing 2011.
