For many species, numerous distribution records exist in the literature, and we manually geo-referenced additional occurrence data from these sources.";
String EngDescr "Our knowledge on global distribution of the four extant horseshoe crab species is inadequate. The aim of this study (and the associated data set) is to improve our understanding of the current biogeographic distribution of horseshoe crabs. To do this we collated all available occurrence information for all four species on the Atlantic coasts of Central and North America, and the coasts of South-East Asia. Occurrence data from the four extant species of horseshoe crabs (Limulus polyphemus, Carcinoscorpius rotundicauda, Tachypleus gigas, and T. tridentatus) were compiled from recent literature, our scientific network, and own field work. The three Asian species C. rotundicauda, T. gigas and T. tridentatus were found to co-occur on the Indonesian islands Borneo and Java.";

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://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").
For details, see the tabledap Documentation.
