ABACUS – a repeated glider monitoring line across the western Mediterranean Sea
Bibliographic record
Abstract
Algerian Basin Circulation Unmanned Survey – ABACUS - has been carried on since 2014 across the Algerian Basin to investigate high resolution variability of the first 1000 m of the ocean and to fill the gap in data collection in this area of the Western Mediterranean Sea.Five deep SLOCUM G2 glider missions were carried out in the AB between 2014 and 2022 by Università degli Studi di Napoli Parthenope, in collaboration with Balearic Islands Coastal Observing and Forecasting System (SOCIB) and the Mediterranean Institute for Advanced Studies (IMEDEA CSIC-UIB), with the participation of scientists from Algeria, France and Canada. A sixth mission (ABACUS 2023) is indeed in progress. ABACUS projects were supported since 2014 through the Trans National Access (TNA) calls of JERICO, JERICO-NEXT and JERICO S3 programmes and through the SOCIB glider facility open access programme.Recently, ABACUS line was also added to the Boundary Ocean Observing Network (BOON) of the OceanGliders programme that proposes the long term and sustained observation of oceanographic features using the unique capabilities of the gliders.To date, a total of 22 deep glider ABACUS transects were realized between the island of Mallorca and the Algerian coast. Each mission had an average duration of about 40 days and was mainly carried out during fall and/or early winter (2014–2018, 2021-2022) or spring (2018, 2022). All the glider surveys were conducted along neighboring SARAL/AltiKa (2014-2016) and Sentinel-3A (2018, 2021-2022) satellite groundtracks. The timing of the glider missions were accurately planned to optimize the synopticity between in situ and remote sensed observations.All the ABACUS gliders were equipped with a glider-customized CTD measuring temperature, conductivity/salinity and pressure/depth; a two-channel combo fluorometer sensor by WetLabs (for Chl-a concentration and turbidity measurement); and an oxygen optode by AADI to measure absolute oxygen concentration and saturation. During the last two missions, the glider was also equipped with a passive acoustic probe to study wind and rain events during the mission, as well as the presence of marine mammals in the monitored area.ABACUS data are freely available through a dedicated webpage and cooperation with new scientists is strongly encouraged. This presentation aims at making the scientific community aware of the importance and possibilities offered by ABACUS and similar glider monitoring lines, as well as at enlarging the ABACUS science team to fully exploit the collected ocean observations.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
