Dissolved black carbon in aquatic environments with an emphasis on lacustrine systems: a review
Bibliographic record
Abstract
Dissolved black carbon (DBC) is the remobilized soluble fraction of black carbon (BC). DBC, present in all aquatic environments, is a heterogeneous mixture of various pyrogenic aromatics. For a long time, oceans were solely considered to be the largest pool of DBC. However, recent research indicates that lakes might also contain significant concentrations of DBC. Anthropogenic BC emissions and seasonal changes driven by climate change could increase DBC flux to glacial and fluvial lacustrine systems with unique effects. In this article, current knowledge concerning the formation, sources, transportation, fate, and environmental implications of DBC in lacustrine networks is presented. Furthermore, ambiguities pertaining to terminology and methodologies used in the separation and quantification of DBC are also reviewed, and research gaps that should be addressed in future studies are highlighted. Constraining DBC dynamics and residence times in lacustrine systems could provide valuable insights into anthropogenic perturbations of the global carbon cycle.

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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
