iTrack Oysters February 2023 Experiment - Environmental and Oyster Health Data
Bibliographic record
Abstract
This data package is a component of the Hakai Institute’s Marna Wet Lab and Caren Helbing (University of Victoria, UVic) collaborative iTrack project investigating environmental effects on eDNA and eRNA. Hakai Institute's Marna Wet Lab experimental research program uses laboratory experiments to evaluate marine organisms' responses to simulated current and future ocean environmental conditions. The overarching objective of Hakai Wet Lab experimental research is to investigate the mechanisms of vulnerability and resilience of a variety of marine species and communities under static or dynamic future environmental conditions, and understand how organisms are responding phenotypically, physiologically and/or genomically to thermal and acidification stress. This experiment was part one of a series of mesocosm experiments and took place at the Marna Wet Lab at Hakai’s Quadra Island Ecological Observatory February 22-27, 2023. The purpose of this experiment was to investigate eDNA and eRNA production and degradation under different pCO2 conditions. Adult Pacific oysters (Crassostrea gigas) were chosen as model organism and exposed to various pCO2 treatments (520 µatm, 950 µatm, and 1200 µatm) under constant temperature (10C). eDNA and eRNA samples were collected while oysters were present (Production phase) and after oysters were removed (Degradation phase). A subsample of oysters from each tank were destructively sampled for weight, size, condition/health and gill and gonad RNA at the end of the experiment. This data package contains the mesocosm temperature and carbonate chemistry data and oyster health data only and will be available upon request until the manuscript has been accepted at which time the data will be made publicly available. In light of the effort required to obtain these data and create data packages, we request all data users that, in addition to following the CC-BY license terms, they give attribution to the data providers and follow fair use guidelines: 1) respect the data providers, and provide helpful feedback on data quality, and 2) communicate and/or collaborate with Hakai Marna Wet Lab researchers and collaborators if you are considering using this dataset for manuscripts or other forms of reporting.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
