String summary "The overall goal of the Estuary Marine Protected Area (EMPA) Monitoring Program is to establish a monitoring framework, including data collection, analysis, synthesis, and reporting to determine the health of estuaries in California and the efficacy of MPA designation in estuaries. As part of the initial phases of the program, we developed standard protocols to assess key estuarine features across different estuaries, coupled with standard data templates and guidance on analysis, synthesis, and reporting, focused on four guiding principles: flexibility, comparability, interpretability, and practicality. We developed 14 SOPs and piloted the framework at 15 estuaries in 2021. For more details on the EMPA program and framework, see https://empa.sccwrp.org. This dataset includes the continuous water logger data collected from 2015, as illustrated in SOP 1. In estuaries without continuous logger deployment, CTD Divers, PME MiniDots, Rugged Trolls, and Hobo Tidbits were deployed to collect temperature, conductivity, dissolved oxygen, and pressure (depth). Replication and length of deployment varied with estuary. In a select number of estuaries, other logger types were used due to existing monitoring; in those locations, that logger data has been included as well. For more details, see SOP 1 on https://empa.sccwrp.org. To simplify data usability, fields from both data and metadata tables have been combined to provide the user with a merged dataset. The metadata table is also included in standalone format.";

Data Access Protocol (DAP) and its
selection constraints.
The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.
Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names,
followed by a collection of
constraints (e.g., variable<value),
each preceded by '&' (which is interpreted as "AND").
For details, see the tabledap Documentation.
