Marine Toxic Substance Surveys from North Atlantic Platforms

Laboratory analyses of water, sediment, and marine organism samples collected from three vessels in the North Atlantic Ocean. Data processed to the NODC F144 standard format includes chemical concentrations, environmental conditions, and sample collection metadata. The National Oceanic and Atmospheric Administration (NOAA) is the authoritative organization for this dataset.

Use Cases

• Analyzing ambient concentrations of toxic substances identified by Chemical Abstracts Service (CAS) codes.
• Correlating pollutant levels with environmental conditions like sea surface temperature, salinity, and tide stage.
• Studying discharge site characteristics including location, depth, distance to shore, and average volume.
• Identifying sampled marine organisms using the 12-digit NODC Taxonomic Code.
• Investigating tar deposit observations on beaches from field surveys.

Strengths

• Data adheres to a standardized format (NODC F144) ensuring consistent structure for chemical and taxonomic codes.
• Includes detailed metadata on sample collection methods, laboratory techniques, and environmental conditions.
• Surveys cover a defined time range from November 1976 to September 1977 across multiple platforms.

Limitations

• Key technical details like row count, column names, and file size are unavailable from all sources.
• Sources conflict on the last updated date, with one listing 2026-04-01 and another listing the end date of the study, 1977-09 15.
