Summary
Description https://www.emodnet-biology.eu/data-catalog?module=dataset&dasid=6648
https://github.com/EMODnet/EMODnet-Biology-Benthos_numeric_abundance
The data product on benthic living modes (Beauchard, 2018), was based on an extensive compilation of data on benthic abundance and biomass. However, this dataset was only present as a data file, without the underlying scripts to reproduce the result. With the present data product, we correct this procedural gap.
This repository contains the scripts used to compile different datasets in this area into a comprehensive summary of available data on abundance and (where available) biomass density of macrozoobenthos. This dataset differs in details from the file underlying the data product on living modes, as it is a new version. However, differences are minor. Datasets were selected that were sufficiently similar in methods for sampling (either boxcore or grab), sampled surface (in the order of 0.1 square meter, although the exact value is variable - it can be found back in the data files) and sieves (1 mm and 0.5 mm sieves were included). For all datasets, abundance was either used directly from the given abundance in the dataset, or calculated from the given counts and area sampled.
The compiled dataset is composed of approximately 80000 samples, many of which are themselves a composite of a number of replicate grabs or cores. Replicates were taken together during the processing of the data. Species recorded in the dataset were filtered as much as possible, based on whether they belong to the macrobenthos. The filtering method was automatic, based on WoRMS information. In general, WoRMS contains good quality trait information on benthic species. However, it cannot be guaranteed that all of the >4000 species are true benthic species, or that all true benthic species are included in the data set.
Information gained during the species selection was fed back to the WoRMS editors and will be used in future to further refine the WoRMS trait data.
The aim of this product is to underly analysis of such characteristics as living modes, bioturbation potential, role in food webs or indicators for environmental changes. Although the maps in the product show all information contained in the database over all years since 1980, time information is stored in the intermediary files and thus in principle available to investigate time evolution in the composition of benthos across Europe. Such applications have not been made, but it is hoped that several of this type of applications will be developed based on the present product.
