"4 replicate samples were collected at each station for faunal analysis. Samples were taken using a Modified van Veen grab with a sample surface of 400cm² and depth penetration up to 20cm. A special net was used for the collection of the epibenthic decapods and small fishes. This net had a a  square opening of 40 cm on each side and it was pulled on the sediment along a 10 m distance. At each station, a sediment sample was taken with a small corer for particle size analysis and estimation of organic matter.
A number of datarecords are uncertain, and are therefore not included in Eurobis.

The results showed that the macrozoobenthic community structure and dynamics at low salinities  (0.3 - 6 psu) in Monolimni Lagoon were investigated monthly. Community structure showed an almost even seasonal periodicity. The main structuring factors of the community in the deeper outer part of the lagoon were water temperature and depth, and in the innermost part, where a Ruppia meadow occurred, were water temperature and predation pressure by crabs and gobies.";

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 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.

• (easy) You can get data by using the dataset's Data Access Form or Subset form. They make the URL for you.
• (easy) You can make a graph or map by using the dataset's Make A Graph form. It makes the URL for you.
• (not hard) You can bypass the forms and get the data or make a graph or map by generating the URL by hand or with a computer program or script.

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.
