California MOCI: MULTIVARIATE OCEAN CLIMATE INDicator
What is MOCI?
MOCI synthesizes a number of local and regional ocean and atmospheric conditions that represent, in a holistic manner, the state of the California coastal ocean. MOCI includes data that are readily available from the Internet so the indicator can be updated and shared regularly via this website.
MOCI captures ENSO events across decades, as well as the intensity and phasing of the most recent North Pacific marine heat wave, dubbed 'The Blob'. It also shows differences in the magnitude and timing of ocean climate variability in different regions off California. MOCI has skill relative to marine ecosystem dynamics from zooplankton to top predators, and therefore may be important to ecosystem-based fisheries and wildlife management.
Most recent MOCI: January 1991 to December 2016.
What data are included in MOCI?
MOCI include seasonal averages of the following data:
- Upwelling Index, NOAA [link]
- Sea level from shore stations, NOAA [link]
- Alongshore wind, sea surface temperature, air temperature, sea level pressure from NOAA buoys [link]
- Regional climate indices:
