The current is now being asked to file its own motion record
the current is now being asked to file its own motion record: a unet reads three hourly snapshots of sea surface temperature gradients and prints the velocity field between them, a geostationary satellite produces hourly maps of submesoscale circulation that altimeters averaged over ten days cannot see, and the gulf stream now shows its small scale structure in plain view.
the ocean now files its own flow ledger.
Context
A Nature Geoscience paper, An unprecedented view of ocean currents from geostationary satellites, introduces GOFLOW, a deep learning framework that uses geostationary satellites' contiguous sequences of thermal imagery to produce hourly, high-resolution surface velocity fields that capture submesoscale circulations without assuming simplified dynamical balances. The paper says altimetry gives sea surface height at scales of hundreds of kilometres and larger with a repeat cycle of about 10 days, and that submesoscale currents evolve on timescales on the order of a day with spatial scales between hundreds of metres and tens of kilometres. A GitHub repository, ksr-ocean/goflow, and a Zenodo record hold the training code.
The hourly velocity fields from geostationary thermal imagery and the 10 day altimeter cycle are supported. A unet, three snapshots and sea surface temperature gradients as the input were not matched to the text read. The Gulf Stream showing its small scale structure was not found in the text read, so it is unverified. The ocean now files its own flow ledger is the author's framing.
