Monthly means of benthic water temperature from long-term monitoring stations at the (a) Elkhorn Slough and (b) Tijuana River National Estuarine Research Reserves. Anomalies (°C) from the long-term mean temperature (averaged across the time range shown) are indicated by positive deviations in red (warmer) and negative deviations in blue (cooler). Continuous data collection began in 2001 and 2005 for ESNERR and TRNERR, respectively. The marine heatwave along the coast of California is clearly visible from 2014 through 2016
