Description
NCEI Accession 0110257 contains chemical, physical, and profile data from the CLIVAR_OVIDE_2008 research cruise aboard the THALASSA. The dataset includes measurements of dissolved oxygen, nitrate, phosphate, silicate, total alkalinity, pH, salinity, and temperature collected in the North Atlantic Ocean between June 10 and July 11, 2008. These data support the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program's mission to quantify changes in ocean heat, freshwater, and carbon dioxide storage and transport.
Use Cases
Quantifying changes in ocean carbon storage based on total alkalinity and pH measurements.
Analyzing water mass properties and circulation using potential temperature, salinity, and hydrostatic pressure profiles.
Studying nutrient dynamics and biogeochemical cycles in the North Atlantic using nitrate, phosphate, and silicate data.
Calibrating and validating ocean biogeochemical models with discrete sample and CTD profile observations.
Strengths
Data collection is part of a systematic, international repeat hydrography program (CLIVAR), ensuring standardized methodology.
Includes a specific suite of co-located chemical and physical parameters (e.g., oxygen, nutrients, alkalinity, temperature, salinity) relevant for carbon cycle studies.
Covers a defined temporal (one month) and spatial (North Atlantic Ocean) range for the 2008 OVIDE cruise.
Limitations
Key metadata is missing or conflicting: row count, file size, and specific column names are unknown across all sources.
License information is not provided, which restricts clarity on reuse permissions.
Sources disagree on the 'last updated' date (2008-07-11 vs. 2026-03-05), creating uncertainty about metadata maintenance.
Provenance
Source
