GYRE Cruise CTD/STD Profiles from the North Atlantic

High-resolution Conductivity-Temperature-Depth (CTD) and Salinity-Temperature-Depth (STD) data profiles were collected by the GYRE research vessel in the North Atlantic Ocean. The dataset covers a 13-month period from June 17, 1984, to July 14, 1985, and was processed by the National Oceanographic Data Center (NODC) into its standard F022 format. It provides nearly continuous vertical profiles of key oceanographic parameters.

Use Cases

• Analyzing vertical structure of temperature and salinity (columns: temperature, salinity/conductivity) for water mass identification.
• Calculating ocean density (column: computed sigma-t) to study stratification and mixing processes.
• Correlating oceanographic casts with environmental conditions (columns: meteorological and sea surface conditions) recorded at the time of sampling.
• Studying temporal and spatial variability of dissolved oxygen or water clarity (possible columns: dissolved oxygen, transmissivity) over the cruise period.
• Using precise station metadata (columns: position, date, time, sampling interval) for geographic analysis of ocean properties.

Strengths

• Data is processed to the NODC's standard high-resolution F022 format, ensuring a consistent structure for analysis.
• Profiles offer fine vertical resolution, with data potentially reported at depth intervals as fine as 1 meter.
• The dataset provides a continuous 13-month time series from a specific research vessel, enabling seasonal studies.

Limitations

• Specific row counts, column names, and dataset size are not provided by any source, limiting preliminary assessment of scope.
• Sources disagree on the 'last updated' date: one platform lists 2026-03-05 (likely a metadata refresh), while another lists the data end date of 1985-07-14.
• The license and original author information are not specified, which may restrict clarity on redistribution terms.
