Description
NOAA Ship Delaware II collected high-resolution CTD/STD and ocean station data in the North Atlantic Ocean from November 5, 1986, to January 30, 1988. The National Oceanographic Data Center processed the data into standard F022 and C100 formats, merging electronic sensor profiles with discrete bottle cast measurements. This dataset provides detailed physical-chemical profiles, including temperature, salinity, and nutrients, for oceanographic research.
Use Cases
Analyzing vertical profiles of temperature and salinity (principal measured parameters) to study water mass structure.
Calculating derived oceanographic properties like density (sigma-t) and sound velocity from the measured data.
Correlating ocean station data with reported meteorological conditions (air temperature, pressure, wind) for air-sea interaction studies.
Using interpolated standard depth level data for comparative analysis across different stations and cruises.
Strengths
Data combines high-resolution electronic CTD/STD profiles with discrete bottle cast measurements, providing complementary detail.
Covers a specific 15-month time range (1986-11 05 to 1988-01-30) from a dedicated NOAA research vessel cruise.
Includes computed parameters like density (sigma-t) and dynamic depth anomaly derived from primary measurements.
Limitations
Key metadata such as row count, column names, and exact file size are unavailable from all sources.
Approximately 5% of the observations were from electronic CTD/STD recorders, with the majority from multi-bottle Nansen casts.
Platforms disagree on the last updated date: Data.gov lists 2026-03-05, while NASA Earthdata lists the collection end date of 1988-01-30.

Geography
North Atlantic Ocean, specifically the NW Atlantic and North Atlantic Ocean
Data is stored in two distinct NODC standard formats: High-Resolution CTD/STD (F022) and Ocean Station Data (C100), which may require specific parsing knowledge.
