Abstract

fetched live from OpenAlex

The Global Ocean Data Analysis Project (GLODAP) is a synthesis effort providing regular compilations of surface-to-bottom ocean biogeochemical bottle data, with an emphasis on seawater inorganic carbon chemistry and 85 related variables determined through chemical analysis of seawater samples.GLODAPv2.2022 is an update of the previous version, GLODAPv2.2021(Lauvset et al., 2021).The major changes are as follows: data from 96 new cruises were added, data coverage was extended until 2021, and for the first time we performed secondary quality control on all sulphur hexafloride (SF6) data.In addition, a number of changes were made to data included in GLODAPv2.2021.These changes affect specifically the SF6 data, which are now subjected to secondary quality control, and carbon data measured 90 onboard the RV Knorr in the Indian Ocean in 1994-1995 which are now adjusted using CRM measurements made at the time.GLODAPv2.2022includes measurements from almost 1.4 million water samples from the global oceans collected on 1085 cruises.The data for the now 13 GLODAP core variables (salinity, oxygen, nitrate, silicate, phosphate, dissolved inorganic carbon, total alkalinity, pH, CFC-11, CFC-12, CFC-113, CCl4, and SF6)GLODAPv2.2021 is an update of the previous version, GLODAPv2.2020(Olsen et al., 2020).The major changes are as follows: data from 43 new cruises 95 were added, data coverage was extended until 2020, all data with missing temperatures were removed, and a digital object identifier (DOI) was included for each cruise in the product files.In addition, a number of minor corrections to GLODAPv2.2020data were performed.GLODAPv2.2021includes measurements from more than 1.3 million water samples from the global oceans collected on 989 cruises.The data for the 12 GLODAP core variables (salinity, oxygen, nitrate, silicate, phosphate, dissolved inorganic carbon, total alkalinity, pH, CFC-11, CFC-12, CFC-113, and CCl4) have 100

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
