"Pressure spectral density (PSD) levels in units of 1 µPa^2/Hz were calculated using Welch's Method in Matlab (FFT length = 48000 points, Hann window length = 48000, FFT overlap = 0%), resulting in PSD estimates of mean-square pressure amplitude (µPa^2) with a frequency resolution of 1 Hz and temporal resolution of 1 second.  For every 1-Hertz (Hz) frequency band from 20 Hz to 24,000 Hz, PSD levels per hour were calculated as the arithmetic mean of mean-square pressure amplitude (µPa^2) over an averaging window of 3600 seconds. PSD levels per hour for each frequency band were converted to decibels (dB re 1 µPa^2/Hz).

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

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{?query}
For example,,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.
