Abstract
Herschel Basin is a natural depression on the southern Beaufort Shelf, which is located in the western Canadian Arctic between the Mackenzie Delta and the Alaskan border. The submarine basin of late Wisconsin age is a natural sediment trap for material eroded along the Yukon coast and through its unique position within the area also a valuable paleoenvironmental archive. During a field campaign in spring 2016, a thirteen meter long sediment core was obtained from the Herschel Basin. \nThe aim of this Master’s thesis was to quantify the amount of carbon, nitrogen and sediment with terrestrial origin throughout the sediment column from the Herschel Basin. The increasing research effort to understand the dynamics of Arctic coasts is justified by their contribution to the global carbon budget and their vulnerability. \nThe results showed that the majority of sediment found in the sediment column of the Herschel Basin could be assigned to a mix of riverine and terrestrial/coastal inputs. However, the individual percentage of each input (marine, fluvial and terrestrial) could not be distinguished, due to lack of data. \nIn conclusion, this thesis showed that in the Arctic nearshore zone coastal erosion affected by climate change will definitely have a negative impact on “[…] climate feedbacks, on nearshore food webs, and on local communities, whose survival still relies on marine biological resources”(M. Fritz et al., 2017).

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 it
