Both estuarine sites (ESNERR and TRNERR) had more MHWs than the open coast site (HMS) in Monterey Bay (34, 21, and 46, respectively).
Continuous data collection began in 2001 and 2005 for ESNERR and TRNERR, respectively.
SST climatology (blue; long-term mean prior to 2013), 90th percentile MHW threshold SST (black), and 2015 observed SST (red) at ESNERR (top), HMS (middle), and TRNERR (bottom).
The total number of anomalous days above the 90th percentile threshold in 2013 was 28, 1, and 57 and in 2017 was 62, 48, and 102 for ESNERR, HMS, and TRNERR, respectively.
San Filippo (1995) caught 312 gray smoothhound (71% of the catch) in 2 years of sampling between 1990 and 1992 in ESNERR. Only four smoothhounds were caught during that same time period in the derbies.
While sampling between early 2003 through late 2004 in ESNERR and the rest of the slough, only nine smoothhounds were caught (6 gray and 3 brown smoothhounds) (Carlisle (9)).
regime shifts, habitat alteration, the creation of ESNERR) also contribute to the abundance and distribution of elasmobranchs.
