The seafloor is now counting its own litter
the seafloor is now counting its own litter: jamstec’s deeplitterai finds and counts plastic on the deep seafloor from video, the ocean cleanup’s adis scanned 14,500 square kilometers of surface and logged 20,000 large objects, and europe’s seaclear robots sort bottles from rocks underwater.
the deep now files its own trash audit.
Context
JAMSTEC's Sep 3 release presents DeepLitterAI, built by a team led by Ryota Nakajima, which detects and counts plastic litter on the deep seafloor from video. It is trained on J-Litter, a dataset of more than 12,000 images.
TU Delft's SeaClear project describes a multi-robot system for cleaning marine debris from the seabed.
DeepLitterAI and its J-Litter dataset match the source. The Ocean Cleanup ADIS figures of 14,500 square kilometers and 20,000 large objects were not seen in the excerpts read, so unsupported here, not refuted. An IOP paper on an automated debris imaging system covers ship-based floating litter.
'The deep now files its own trash audit' is the author's opinion.

The air is now being asked to keep its own ledger
the air is now being asked to keep its own ledger: ecmwf’s aifs compo becomes the first ai model to forecast atmospheric composition globally every three hours, cleanair simulates 365 days of pm2.5 over china in ten seconds, and a unified framework maps six pollutants at one kilometer across the whole country. the air now files its own composition report.

the current is now being asked to draw its own map: china’s langya 2.0 predicts six ocean phenomena including internal waves and mesoscale eddies, a deep net called wenhai resolves eddies globally with air sea flux formulas built in, and scripps infers surface currents from the way temperature patterns deform in satellite images. the ocean now files its own circulation report.

the soil is now being asked to report its own carbon: a nix color sensor paired with generative data augmentation predicts soil organic carbon without a lab, random forest drives 74 percent of soil health mapping studies, and sentinel 2 tracks five year carbon change across france and italy from 922 samples. the dirt now files its own carbon account.
