Abstract

fetched live from OpenAlex

Data on the zooplankton community structure, gut evacuation rate
\nand carbon content of zooplankton faecal pellets were used for assessing the
\ncontribution of zooplankton to vertical carbon fluxes in the White and Kara
\nSeas. The results revealed strong regional and seasonal variations of pellet
\ncarbon input related to differences in structure and dynamics of the
\nzooplankton communities in the regions studied. In the deep regions of the
\nWhite Sea, maximum daily pellet carbon flux from the 0-50 m layer was
\nobserved in the spring. It reached 98 mg Corg m-2 day-1 and coincided with a
\nstrong predominance of the large arctic herbivorous copepod Calanus
\nglacialis in the surface layers. In summer and fall, it decreased by 1 to 2 orders
\nof magnitude due to migration of this copepod to its overwintering depths. In
\ncontrast, in the shallow coastal regions, the pellet production was low in
\nspring, gradually increased during summer and reached its maximum of 138
\nmg Corg m-2 day-1 by late summer to beginning of autumn. Such a seasonal
\npattern was in accordance with the seasonal variation of abundance of major
\npellet producers, the small boreal copepods Acartia bifilosa, Centropages
\nhamatus, and Temora longicornis. In the estuarine zone of the Kara Sea, the
\npellet flux was mostly formed by pellets of brackish-water omnivorous copepods.
\nIt varied from 35 mg Corg m-2 day-1 in 1997 to 96 mg Corg m-2 day-1 in 1999.
\nIn the central Kara Sea with its typical marine community, the daily flux
\nreached 125 mg Corg m-2 day-1 in summer. The results of our calculations indicate
\nthat both in the White and Kara seas zooplankton pellet carbon contributes
\nup to 30 % to the total carbon flux during particular seasons.

Teacher imitation

Not 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.
