Abstract

fetched live from OpenAlex

interaction. In this study, preliminary results from Boswell Lake, a small hard water system in the boreal forests of central in British Columbia, Canada, are presented. The sediment record has been analysed using a range of geovhemical, sedimentological and biological analytical techniques to provide a high-resolution record of carbon cycling over the Late-glacial and Holocene. Signi[U+FB01]cant changes in carbon [U+FB02]ux to the lake are recorded and linked to changing climatic conditions and anthropogenic land use / land cover changes. The preliminary results from Boswell clearly show that since the end of the last ice age, anthropogenic activity is the dominant driver of change in the terrestrial carbon cycle. During the pre-European time during the Holocene, only small changes in the largely inorganic C-deposition occurred. This indicates that the regional C-cycle in boreal forests is relatively stable within the range of natural Holocene climatic variability. Since the middle of the 19th century, increased [U+FB01]re frequency and logging has led to greater rates of autochtonous organic C depostion. This shift towards the deposition of organic material is probably caused by the release of nutrients from decaying biomass, leading to a eutri[U+FB01]cation of the lake. The signi[U+FB01]cance of this sink in the regional carbon cycle is yet unclear. Overall, the paleolimnological analysis of the Boswell Lake sediments indicate that regional C-cycles have experienced signi[U+FB01]cant changes during the Holocene, with greatest differences at the late-glacial-Holocene and Holocene-Anthropocene boundary.

Full frame distilled prediction

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.
