Oceanography and geodynamics in the NW Atlantic and the Baffin Bay - Cruise No. MSM09 - July 23 - October 29, 2008 - Bremen (Germany) - Ponta Delgada (Azores)
Bibliographic record
Abstract
The Maria S. Merian Cruise MSM09 comprised three legs spanning over 91 days at sea, carrying out research in the western North Atlantic, the Labrador Sea and the Baffin Bay. The multidisciplinary programme of the cruise has been shared among six research groups, which collected data and material to study physical oceanography of the region, paleoclimatology, plankton ecology and the development of the oceanic basin between Greenland and Canada. The first leg (MSM09/1) investigated the North Atlantic subpolar gyre, a key region for water mass transformation in the North Atlantic. The objective was to collect measurements to constrain the transport variability in the gyre and to characterise water mass variability and transformation in the Newfoundland basin. Complementary oceanographic observations were obtained during the first half of the second leg (MSM09/2) for the Labrador Sea, including convection activity and variability of the boundary current. With the ultimate aim to improve our ability to interpret paleoenvironmental conditions in glacial high-latitude oceans, the biological and paleoceanographical investigations during the second half of leg MSM09/2 were focused on the characterization of the habitat of planktonic and benthic foraminifera and its relationship to ambient hydrological parameters, and the way the ecological signal is transferred and preserved in the sedimentary record. Deep crustal seismic profiles, accompanied by magnetic and gravity surveys and heat-flow measurements have been conducted during the third leg (MSM09/3) in order to investigate the extension and subsidence of the continental and transitional crust in the Davis Strait and the evolution of oceanic crust in the Labrador Sea and Baffin Bay. These data will provide the basis for palaeobathymetric reconstructions which will describe the break-up and the ocean basin evolution between Greenland and Canada and which will be used for palaeoceanographic modelling.

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.
