Main features

  • Download and import ICES DATRAS survey data
  • Read, write, clean, and subset datras_raw objects
  • Reproduce key components of the FishGlob data-processing workflow
  • Estimate swept area and standardise haul metrics
  • Calculate numbers- and weight-at-length distributions
  • Aggregate total numbers and biomass by haul and length group
  • Support species harmonisation and WoRMS-based taxonomic information
  • Visualise survey structure, catch composition, and length distributions
  • Convert DATRAS data into FishGlob-like formats for downstream analyses

Notes

  • This is an early beta release and the API may still change.
  • Additional documentation, vignettes, and workflow examples are under development.
