Sediment was sampled with a Reineck boxcorer (60 x 30 x 30 cm). In order to detect spatial variations in their distribution, both the biotic (macrofauna) and abiotic (grain size, porosity, ..) component of the sediment was studied. The oxygen flux to the sediment has been measured as an estimation of the rate of benthic mineralization, and the contribution of macrobenthos in total sediment respiration has been calculated. The present dataset contains data on macrobenthic biomass and density and several sediment characteristics. Also, environmental characteristics of the sampling locations can be found.";

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.
