String summary "Fisheries Monitoring in Ocean Wind 01. One summer survey once per year pre-construction in 2022 and 2023. Target for each tow is 5 minutes at 2.5 knots with a goal of twenty stations in the lease area and ten at the control site. The dredge is a modified commercial clam dredge to better sample younger clam sizes (Munroe et al., 2023). For each tow, the total volume of clams caught, and the number of individual clams caught will be recorded. The realized tow distance will be calculated from dredge sensor data that records time on bottom and time hauled back, and vessel track recordings.";

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.
