| attribute | NC_GLOBAL | summary | String | Forage species such as Pacific sardine, northern anchovy, and market squid are critical ecological links between the planktonic food web and higher trophic levels in the California Current System, as well as supporting valuable fisheries. Environmental variability drives large fluctuations in their abundance and distribution. This dataset includes the outputs of Species Distribution Models (SDMs) for 6 key forage species, combining multiple survey datasets with environmental fields from a high-resolution Regional Ocean Modeling System (ROMS) developed at the University of California - Santa Cruz, and the Copernicus-Globcolour level 4 interpolated surface chlorophyll product (https://doi.org/10.48670/moi-00281). The sardine and anchovy SDMs also included predictors indexing stock biomass (MacCall et al. 2016; Kuriyama et al. 2022; Kuriyama et al. 2024). As temporally continuous salinity fields are not available from the UCSC ROMS, we included a measure of the distance to the nearest major river (mean > 50,000 CFS discharge) in the herring SDM, to capture the association of this species with estuaries. The species represented are Pacific sardine (Sardinops sagax), northern anchovy (Engraulis mordax), market squid (Doryteuthis opalescens), Pacific herring (Clupea pallasii), jack mackerel (Trachurus symmetricus), and Pacific mackerel (Scomber japonicus). Results from two different SDMs are shown: Generalized Additive Models and Boosted Regression Trees, and both models predict the probability of occurrence of each species. The model outputs are generally similar, but the BRTs can be more prone to producing offshore artefacts, especially for market squid and jack mackerel. We used data from the NOAA Southwest Fisheries Science Center Coastal Pelagic Species and Columbia River Predator (Emmett et al. 2006) trawl surveys to train all SDMs, with the exception of market squid, where juvenile salmon survey data were used instead (see Chasco et al. 2022 for description of these data). More details on SDMs are available in Muhling et al. (2019); Fennie et al. (2022), and Quezada et al. (2023). Important caveat for the sardine SDMs: these models use spawning stock biomass from the stock assessment as an indicator. Since 2022, Japanese sardine (S. melanostictus) have been detected in the California Current System in increasing numbers. These animals are excluded from the stock assessment using genetic identification, so there are likely to be more total sardine in the region than predicted by the sardine SDM. These outputs are free to use, but we strongly recommend contacting Barbara Muhling (Barbara.Muhling@noaa.gov) before working with them, to ensure complete understanding of the details and caveats. Fields are updated on ERDDAP about once per year, but additional updates can be pushed upon request.
