Researchers aboard the @sikuliaq departed today from San Diego, CA for the 2026 West Coast Ocean Acidification (#WCOA26) mission. Scientists will measure coast-wide ocean biogeochemical and physical conditions and how changing conditions are affecting marine life and ecosystems.
ALT Scientists retrieve a rosette of CTDs, tubes with sensors that measure ocean chemistry and other conditions above calm waters. WCOA 2026 will deploy this tool along the West Coast to assess the status of ocean acidification and its impacts on marine resources. Credit: NOAA

🔬 Spotlight: Synchro – Driving Innovation in Ocean Tech
CeNCOOS joined the team at Synchro, a cutting-edge ocean tech testbed, for a day of fieldwork in Monterey Bay 🌊
We're testing scalable tools that could transform how we observe the ocean 👇

💡 Why eDNA?
It reveals hard-to-see marine life—like elusive fish or whales—through genetic traces in water or air.
A game-changer for ocean observing systems like CeNCOOS.

🚨🌊 During the recent West Coast tsunami warning, water level sensors across California picked up the signal in real time.
See it for yourself on the CalOOS Portal—just turn on the “Water Level” filter: data.caloos.org/?ls=0Rs8zqGb…
Ocean observing in action!
California Department of Public Health has removed warnings that advised against eating recreationally harvested bivalve shellfish from the waters of Marin County.

#ICYMI @CeNCOOS featured Dr. Julia O'Hern, our Associate Director of Cetacean Conservation Biology, in their 'Voices of the Region' series 🐳‼️ Read now to learn how our experts and partners work together to help whales in the Bay at bit.ly/4lNEBaI.

How many IOOS-powered assets are monitoring our #coastalwaters? Assets like radar, buoys, gliders, sensors, and more are collecting real-time data to keep communities safe, economies strong, etc. Explore them all: ioosassociation.org/data-por…

Notably stark contrast between temperatures in NorCal (well abv avg and into 80s!) and SoCal today (well below avg and chilly!) thanks to departing cold low, which brought cold air aloft but subsequently caused downsloping/compressional heating amid offshore flow in north. #CAwx
ALT Map depicting this afternoon's temperature anomalies across CA (as depicted by ECMWF). There is a notable "dipole," with very warm conditions across NorCal and very cool conditions across SoCal.
ALT Map depicting this afternoon's geopotential height anomalies across CA and the West (as depicted by ECMWF). There is a departing low (area of low GPH) over southeastern California.
Clear signs of spring upwelling (deep blue) off SF Bay and along the North Coast. Some nice eddies setting up as well.
Hope everyone enjoys the fog!

California scientists fear loss of critical services under the Trump administration’s recommendation to reduce NOAA’s budget by $1.7 billion.

Funding at Risk!! CeNCOOS provides vital support to national security, economic growth, public health and safety, and responsible coastal management. Elimination of IOOS Regional Observations funding will end CeNCOOS services. mailchi.mp/9baa1cc6c2e4/cenc…
