Use of the data on this data-set, either in scientific presentations, or in published papers, should include appropriate acknowledgement. To avoid overlapping of research studies and for dataset administrative purposes, interested users should contact us to determine possible overlap with current research topics. Suggestions for joint analysis leading to collaboration are always welcomed. 

Please Contact Us via e-mail to tell us how you are using the data. This is for our own interest so that we can monitor how much and for which purpose the data is being used. The data is only available for non-commercial use.";

    String EngDescr 
"Beginning in 1988, through the work of the Plymouth Marine Laboratory Zooplankton Group, a programme of weekly observations was started at L4. 

No formal research programme was proposed, the time-series exploiting the activities of the PML small boats in an opportunistic way as by-product of their other sampling activities (e.g., collection of live plankton, sea-water, trawling for fish and squid).  Over the next 20 years increasing numbers of parameters were measured at L4, including CTD, nutrients, optics, primary production as well as the fish trawl surveys carried out by the MBA.  Recently measurements of the DNA and bacterial bio-diversity have been added.  Since 2006, the phytoplankton and zooplankton series have fallen under the auspices of the Western Channel Observatory, a UK Natural Environmental Research Council funded project.";

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
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.
