Northwest Atlantic Ocean Water Chemistry and Physics Data from 1983

Water physics and chemistry data were collected over two days in February 1983 in the Northwest Atlantic Ocean. The dataset was submitted by the National Ocean Service and processed by the National Oceanographic Data Center to its standard F004 format. It contains measurements from moored current meters and bottle casts.

Use Cases

• Analyzing relationships between physical parameters like temperature, density (sigma-t), and current velocity components.
• Studying chemical concentrations including salinity, oxygen, ammonia, nitrate, phosphate, and chlorophyll.
• Investigating short-term environmental conditions during the cruise through included station and site information.
• Calibrating or validating regional oceanographic models with in-situ measurements from a specific time period.

Strengths

• Data adheres to a documented standard format (NODC F004), ensuring structured measurement reporting.
• Collection method is specified (moored current meter and bottle casts), providing context for data granularity.
• Temporal coverage is precisely defined as February 8-9, 1983, offering a focused snapshot.

Limitations

• Exact row count, column names, and dataset size are unknown across all sources.
• Sources conflict on the last updated date: datagov lists 2026-04-01, while nasa_earthdata lists 1983-02-09.
• License information is not provided, restricting clarity on reuse permissions.
