Get Offshore Seabed Sediment Data items
This layer provides particle size analysis associated with offshore sampling activities. It contains a variety of types of particle size analysis; these include folk analysis, gravel, sand and mud percentages, phi and half-phi sand analysis and carbonate analysis based on gravel, sand and mud fractions. Note these data are primarily from the seabed, but contain some data at depth. BGS data input methodologies used in the past between northern and southern parts of BGS vary. The underlying PHI data values are sound except where human error may have occurred. Where the sand PHI weight analysed was a split/fraction of the total sand component of the sample the northern and southern parts of BGS adopted differing data recording methods. The BGS northern part of BGS generally recorded the sand PHI weight for each PHI interval for the actual volume of sample analysed. The BGS southern part of BGS generally took the sand PHI weight for each PHI interval then calculated the percentage of each PHI sand interval and used these values to back calculate the PHI sand weight representative of the total sand which was then recorded in the database.

Query parameters
The optional f parameter indicates the output format which the server shall provide as part of the response document. The default format is GeoJSON.
The optional lang parameter instructs the server return a response in a certain language, if supported. If the language is not among the available values, the Accept-Language header language will be used if it is supported. If the header is missing, the default server language is used. Note that providers may only support a single language (or often no language at all), that can be different from the server language. Language strings can be written in a complex (e.g. "fr-CA,fr;q=0.9,en-US;q=0.8,en;q=0.7"), simple (e.g. "de") or locale-like (e.g. "de-CH" or "fr_BE") fashion.
Only features that have a geometry that intersects the bounding box are selected.The bounding box is provided as four or six numbers, depending on whether the coordinate reference system includes a vertical axis (height or depth).
The optional limit parameter limits the number of items that are presented in the response document (maximum=1000000, default=10).
Indicates the coordinate reference system for the results.
Indicates the coordinate reference system for the given bbox coordinates.
The properties that should be included. The parameter value is a comma-separated list of property names.
Additional "free-form" parameters that are not explicitly defined
This option can be used to skip response geometries for each feature.
The optional offset parameter indicates the index within the result set from which the server shall begin presenting results in the response document. The first element has an index of 0 (default).
