Cool inset map from this "Geologic Map of the San Francisco Bay Region," by Graymer, et al. (2006). ngmdb.usgs.gov/ngm-bin/pdp/...
It shows the blocks of crust sliced & diced by Bay Area faults, and how much & in what direction they have moved in the past 34 million years.

Ocean stratification in a warming climate - Nature Reviews Earth & Environment
Ocean stratification — density-related layering of seawater — influences oceanographic and climatic processes. This Review outlines observed and projected changes in stratification, noting a 0.8% dec−1 increase in 0–2,000 m stratification from 1960–2024, and a further 1.4% dec−1 increase by 2100 under SSP2-4.5.
