String comment1 "A CREMP survey station was originally 3 parallel adjacent image transects that were used to determine percent cover. In 2011 we reduced this to only using the middle of the three transects. To make all the datasets consistant the 1996 - 2010 datasets were modified to only reflect the percentages based on the middle transect for all years. This would make the dataset consistent with how it is currently being reported in our reports and elsewhere.";

The core field methods continue to be underwatervideography and timed coral species inventories. Findings presented in this report include datafrom 109 stations at 37 sites sampled from 1996 through 2008 in the Florida Keys and 1999 through 2008 in the Dry Tortugas. The report describes the annual differences (between 2007 and 2008) in the percent cover of major benthic taxa (stony corals, octocorals, sponges, and macroalgae), mean coral species richness and the incidence of stony coral conditions. Additionally, it examines the long-term trends of the major benthic taxa, five coral complex, Montastraea cavernosa, Colpophyllia natans, Siderastrea siderea, and Porites astreoides) and the clionaid sponge, Cliona delitrix.";

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").
