String acknowledgment "Many researchers collected samples from R/Vs and from commercial catch. Special thanks to Darrin Bergen, who collected specimens as extensively as the CDFG R/V Mako allowed him to roam from San Diego in a day (some might argue farther). Joelle Sweeney contributed otoliths and corresponding length and weight data for Oncorhynchus mykiss, Sebastes jordani and Sebastes goodei. Size data and specimens for Oncorhynchus gorbuscha were provided by Steve Moffitt and Dion Oxman of Alaska Department of Fish and Game, Joe Orsi of Alaska Fisheries Science Center, and Tyler Zubkowski of Department of Fisheries and Oceans Canada. Roberta Folk, Jim Carretta, Terry Farley, Amy Betcher, Rachel Struch, Morgan Martin, and Stephanie Nehasil helped measure and weigh specimens in the lab. Digital microscope equipment and instruction were provided by Wayne Perryman and Morgan Lynn. Microgram scales for weighing otoliths were provided by Bev Macewicz, Barbara Javor, and Jeff Seminoff. Collections managers and staff provided extensive access and expertise, including Ben Frable and H. J. Walker of the Scripps Institution of Oceanography (SIO) Marine Vertebrate Collection, Linsey Sala of the SIO Pelagic Invertebrate Collection and Eric Hochberg of Santa Barbara Museum of Natural History. Christine Thacker, Rick Feeney, Jeff Seigel, and Neftali Camacho of the Natural History Museum of Los Angeles County provided otoliths from the Fitch Otolith Collection.";

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://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.
