The forest under the waves is now being mapped like a city
the forest under the waves is now being mapped like a city: ucla deep learning reads satellite imagery to track california kelp at new resolution, kelpwatch.org makes the maps public, and the data shows how the canopy recovered after the 2014 to 2016 marine heatwave.
the sea now keeps its own forest inventory.
Context
UCLA's newsroom says satellite imagery with deep learning produced the most high-resolution statewide maps of California kelp forests to date, showing how kelp survived or declined after the 2014 to 2016 marine heatwave. The work was funded by the California Ocean Protection Council and The Nature Conservancy.
A separate UCLA study found kelp inside marine protected areas rebounded faster after those heatwaves.
The UCLA deep learning maps and the 2014 to 2016 heatwave match the source. The post's claim that kelpwatch.org makes the maps public was not seen in the excerpts read, so unsupported here, not refuted. The Kelpwatch tool itself is described in a 2023 PLOS One paper.
'The sea now keeps its own forest inventory' is the author's opinion.
