Nutrient concentrations and meteorological measurements were collected from the Pacific Ocean during a research cruise. The dataset contains profiles from CTD and bottle casts conducted over a 48-day period from February to April 1990. Data were collected by the Pacific Marine Environmental Laboratory (PMEL) and submitted to NOAA's National Centers for Environmental Information.
Use Cases
- Analyze correlations between meteorological conditions (e.g., wind speed, air temperature) and surface ocean nutrient concentrations.
- Model vertical nutrient profiles (e.g., nitrate, phosphate, silicate) from CTD cast depth and salinity data.
- Investigate spatial and temporal variability of ocean chemistry during the 1990 cruise period across the Pacific sampling stations.
Strengths
- Data collection spans a 48-day continuous cruise period from 1990-02-24 to 1990-04-12.
- Includes complementary data types: nutrient chemistry from bottle samples and physical profiles from CTD casts.
Limitations
- Dataset is a single, historical snapshot from 1990 with no subsequent updates.
- Unknown sample size (row count) and specific column schema limit reproducibility of analyses.
- Geographic coverage is limited to the specific cruise track of the NOAA Ship MALCOLM BALDRIGE.
