Calibrated global 2019 - 2024 macroplastic abundance dataset from Automated Debris Imaging System

This dataset contains geolocated numerical abundance observations of floating ocean macroplastics, based on over 20,000 validated items. The observations have been made with the novel Automated Debris Imaging System, based on shipborne photo timelapses of GoPro action cameras and a Yolov5 object detection model. The numerical abundance observations are aggregated to 10 km segments, while the individual plastic items can be found as JPG thumbnails and their metadata in a CSV file. The segments are available as geopackage (GPKG) for direct use in GIS applications, or as CSV, based on the segment centroids.The individual validated objects are described in the objects.csv table, which can be matched to the segments table using the SegmentID field.The archive named Object snippets.zip contains an object snippet for every row in the objects.csv table, which can be matched using the ID field.The attributes for the segments and objects files are detailed in the readme file. Object photo snippets:The filenames represent the ID field in the object attributes table. Due to two different intermediate processing versions, some snippets contain imprinted bounding box information; others contain only the snippet itself.
