In 2015, U.S. Geological Survey (United States Geological Survey (USGS)) and U.S. National Park Service (Naval Postgraduate School (NPS)) researchers began a collaborative study to determine coastal circulation patterns and water-column properties along north-central Tutuila, in an area focused on NPSA's Tutuila Unit and its coral reef ecosystem. The continuous measurements of waves, currents, tides, and water-column properties (temperature and salinity) from these instrument deployments, coupled with available meteorological measurements of wind and rainfall, provide information on nearshore circulation and the variability in these hydrodynamic properties for NPSA's Tutuila Unit. These data will complement ongoing and future water quality efforts along north-central Tutuila and in NPSA that will provide baseline information to determine impacts resulting from management and (or) climate change. The field experiment included collection of continuous oceanographic data, as well as spatially extensive shipboard surveys and drifter deployments in NPSA from February through July 2015. The goals of the experiment were to understand controls on flow patterns and water-column properties in the NPSA. To do this, the USGS and NPS set out to complete the following tasks: Measure temporal variability in wave heights, wave periods, wave directions, current speeds, current directions, temperature, and salinity. Measure spatial variability in current speeds, current directions, temperature, salinity, chlorophyll, turbidity, and light transmission. Track pathways of Lagrangian ocean surface current drifters to understand transport pathways of buoyant surface material (coral larvae, debris, search-and rescue, etc). Compile modeled deep-water wave height, wave period, and wave direction data and locally-measured wind speed, wind direction, rainfall and barometric pressure. Determine the influence of oceanographic and meteorologic forcing on circulation patterns and water-column properties along north-central Tutuila and in NPSA waters. This data release includes data from acoustic doppler current profilers, conductivity-temperature-depth profilers, satellite-tracked Lagrangian surface-current drifters, and other time-series oceanographic data.

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").
