Warm Water Surge Threatens Bay Area Marine Life
3 Nov
Summary
- El Niño heating oceans causes rising sea levels and tidal flooding.
- A new surge of warm water is heading north from Southern California.
- Marine wildlife faces potential declines and breeding season disruption.
Recent tidal flooding experienced around the Bay Area is attributed to El Niño warming ocean waters, causing sea levels to rise. A new warning indicates a substantial surge of 65- to 75-degree water is moving north from Southern California, driven by a Kelvin wave originating at the equator. This event is expected to exacerbate the stress on the region's marine ecosystem.
Scientists anticipate the strongest effects of this warm water surge this winter, with potential impacts on next year's breeding seasons for seabirds and marine mammals. While species can adapt to gradual changes, rapid warming events can lead to declines, as observed with thousands of starving murres washing ashore recently. Conservationists are working to save these birds, though the full extent of the new warm water surge's impact remains uncertain.
Unusual wildlife behavior has already been noted, including the sighting of an olive ridley sea turtle, typically found in tropical waters, off the Monterey coast. The water temperature was recorded at 68 degrees, significantly warmer than the usual 58-60 degrees. This warming also threatens kelp forest health, which cannot survive in such elevated temperatures, raising concerns about broader ecological shifts.
