    String summary 
"Annual breeding population estimates for Brandt's Cormorant, Cassin's Auklet, Common Murre, Double-crested Cormorant, Pelagic Cormorant, Pigeon Guillemot, Tufted Puffin, and Western Gull at the Farallon Islands. Data presented are the number of breeding adults estimated for each season.

Breeding population estimates for most species are based on either direct counts of animals or nests. Cassin's auklet estimates are based on the percent change in burrow/crevice density within a series of index plots. This relative change is then applied to the last full census from 1989 to arrive at a current population estimate. See the SEFI Research Plans and Protocols document under Research Tools for more information on how these estimates were determined.

Note: Cassin's auklet population estimate is for Southeast Farallon Island only.";

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.

(easy) You can get data by using the dataset's Data Access Form or Subset form. They make the URL for you.
(easy) You can make a graph or map by using the dataset's Make A Graph form. It makes the URL for you.
(not hard) You can bypass the forms and get the data or make a graph or map by generating the URL by hand or with a computer program or script.

Tabledap request URLs must be in the form
https://upwell.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://upwell.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.
