Interagency Ecological Program: Integrated Dataset of Phytoplankton Enumeration Data in the San Francisco Estuary, 1992-2024

Phytoplankton community composition is an important driver of zooplankton productivity and food supply for higher trophic levels in the San Francisco Estuary. Various monitoring surveys throughout the region collect phytoplankton enumeration data dating back to the 1990s. These include surveys from the CA Department of Water Resources (CADWR), CA Department of Fish and Wildlife (CDFW), the US Bureau of Reclamation (USBR), and the US Geological Survey (USGS). These surveys collect data via various sampling and laboratory methods which are not always directly comparable. This integrated dataset includes both enumeration counts and well-documented metadata to allow for informed decision-making in the integration of these data. It also standardizes taxonomic names between groups via a key list. Note that, in this dataset, we make conservative decisions about taxonomic resolution to ensure maximum compatibility between groups. For more detailed metadata and higher taxonomic resolution, refer to individual surveys’ publications or reach out to their primary contact (see "PESP_survey_metadata" file). ## About This Federated Record This CNRA Open Data Platform record is based on metadata federated from the Environmental Data Initiative (EDI) Data Portal. Its purpose is to improve the discoverability of the data package through the CNRA Open Data Platform. The EDI Data Portal is the repository of record for this data package. Metadata, resource links, and supporting information displayed here may not reflect the latest updates available in EDI. Resources shown here—including Full Metadata, Provenance, and Data Quality Report—are provided to help users understand and evaluate the data package and the supporting information available from EDI. For the current data package, citation, DOI, data files, metadata, provenance, data quality documentation, revision history, and other supporting information, refer to the EDI data package landing page: https://portal.edirepository.org/nis/metadataviewer?packageid=edi.2209.3&key=vqSpNwnbe91Bi8trB5RY25CoPD4 Access requirements, permissions, and authorization policies for resources hosted by EDI are established and managed independently of the CNRA Open Data Platform.
