A crossroads of the Atlantic Meridional Overturning Circulation : the Charlie-Gibbs Fracture Zone data report August 2010 � June 2012
Bibliographic record
Abstract
This is the final data report of all mooring data collected by the Woods Hole Oceanographic Institution in 2010-2012 during the experiment A Crossroads of the Atlantic Meridional Overturning Circulation: The Charlie-Gibbs Fracture Zone. The objectives of this experiment were (1) to obtain an improved direct estimate of the mean and low-frequency variability of the deep westward transport of the Iceland-Scotland Overflow Water through the Charlie-Gibbs Fracture Zone (CGFZ), and (2) to gain a better understanding of the causes of the low-frequency variability in the transport of overflow waters through the CGFZ, especially of the role of the North Atlantic Current in generating this variability. The mooring deployment and recovery cruises were on German research vessels, courtesy of Drs. Monika Rhein and Dagmar Kieke: the R/V Meteor cruise M82/2 in August 2010 and R/V Maria S. Merian cruise MSM 21/2 in June 2012, respectively. The CGFZ moored array complemented other moored arrays being maintained by German scientists just west of the CGFZ (Pressure Inverted Echo Sounders, or PIES) and the Faraday Fracture Zone (current meter and microcat moorings). A set of eight moorings were set up across the CGFZ to measure the intermediate and deep water variability for a two-year period, from a depth of 500 m to the ocean floor. The moorings held a total of three McClane Moored Profilers (MMPs), 10 Nortek and 18 Aanderaa current meters, and 36 Seabird MicroCATs, deployed from 18-20 August 2010 through 28-30 June 2012. This yielded a nearly two-year record of velocity, temperature, salinity and pressure. The MMPs profiled every five days, and resulted in a high-resolution time series of temperature, salinity, pressure and velocity data across the interface between the generally eastward flowing Labrador Sea Water carried underneath the North Atlantic Current, and the westward flowing deep Iceland-Scotland Overflow Water.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
