NOAA NCEI data contains chemical analyses of seawater samples collected from 1974 to 1982. It includes cruise information, station positions, dates, times, and measurements for sample depth, temperature, salinity, and density. Reported chemical parameters cover dissolved oxygen, nutrients, organic carbon, chlorophyll, and hydrocarbons.
Use Cases
- Modeling dissolved oxygen concentration from sample depth, temperature, and salinity data.
- Analyzing temporal trends in nitrate, nitrite, and phosphate levels across different cruise stations.
- Correlating total chlorophyll and total phaeophytin measurements with sample depth and geographic position.
- Investigating relationships between apparent oxygen utilization, percent oxygen saturation, and inorganic phosphate.
- Assessing spatial distribution of total recoverable petroleum hydrocarbons relative to station date and location.
Strengths
- Data collection spans 8 years from 1974 to 1982.
- Includes a wide range of chemical and biochemical parameters such as dissolved oxygen, multiple nutrients, and hydrocarbons.
Limitations
- Specific row count, sample size, and geographic coverage are unknown.
- Data is temporally stale, with the last update recorded in 1982.
