| attribute | NC_GLOBAL | history | String | 14 days of daily chlorophyll and sea surface temperature satellite data were obtained from:
https://oceandata.sci.gsfc.nasa.gov/opendap/VIIRS/L3SMI/contents.html
and compiled into 14-day composites. The data were then applied to
the habitat model to obtain the potential habitat fields. |

| attribute | NC_GLOBAL | summary | String | A habitat model of potential sardine distribution in the California Current based on Zwolinski and Demer 2024 (https://onlinelibrary.wiley.com/doi/full/10.1111/fog.12664). This model integrates all available egg-presence data from 1998 to 2019, offering a more comprehensive understanding of sardine distribution than a previous iteration (https://academic.oup.com/icesjms/article/68/5/867/652826). This model is used to attribute acoustic-trawl survey observations and fishery landings to the northern subpopulation of Pacific Sardine to inform the stock assessments (https://repository.library.noaa.gov/view/noaa/61071). |
