Abstract
Microplastics (MPs) are considered to be synthetic polymeric material <5mm in size and originate from either primary sources, those manufactured to be <5mm in size, or from the breakdown of larger pieces by physical, chemical and radioactive processes. These fragments may become small enough to allow them to be ingested and bio-accumulate. MP pollution has been recorded in marine sediments in nearly all of the Earth’s oceans and has been recently quantified in Greenlandic sea ice and Greenlandic sea way sediments. An independent research project with Drs Matthew Ross, Anna Pienkowski and Mark Furze in the Fall of 2017 quantified MP pollution in Frobisher Bay sediments. Eleven samples were collected during the 2017 summer expedition aboard the CCG Amundsen ice breaker. They were taken in a linear fashion within Frobisher Bay allowing for the correlation of MP deposition and proximity to anthropogenic habit in the area. Extraction procedures were based on modifications of standard methods developed by the National Oceanic and Atmospheric Administration. This includes four procedures which aimed to separate MPs from sediments and micro-organic materials by exploiting differing density and dissolution properties. We collected sieved MPs of five size ranges via vacuum filtration onto 0.45μm filter paper for analysis. Subsequent visual mapping allowed large scale processing of data and pinpoints areas of interest for spectral analysis. Using Raman microscopy, polymer identification may allow us to understand sources and migratory patterns of MPs. This process allowed us to quantify MP contamination in Arctic sediments enhancing global data sets for future research into MP source, transport and fate. We can conclude that MP contamination is found at higher concentrations nearest the City of Iqaluit relative to mouth of Frobisher Bay with averages ranging between 13.08 MPs per gram of sediment (mp/gs) and 5.31 mp/gs respectively. This suggests that relatively small communities can have a significant impact on MP contamination levels in secluded oceanic bays. I look forward to the opportunity to further disseminate microplastic contamination research as it is vital in increasing public awareness and pressure on policy makers to initiate mitigation and reclamation of this very important global issue. *Indicates presenter

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
