Descrição
The Limnodata Neerlandica data set contains the data of more than 30 years systematic and project based sampling of Dutch, mainly freshwater, waterbodies. Data originate from 37 data providers; 26 water boards, the provinces and the Ministry of Transport, Public Works and Water Management. Over 20,000 sample points were used. The main purpose of the dataset is monitoring the quality of Dutch surface waters. Next to the biological characteristics also a-biotic data were sampled and stored alongside the biotic data. Observations are available from phytoplankton, diatoms, aquatic and riparian plants, macro-invertebrates and fish. The data were collected on a yearly base. The taxonomy has been validated according to the Dutch standardised checklist of aquatic species. Update January 2015: Added data for 2011 and 2012. Enhanced taxonomic and locality data fields.
Registros de Dados
Os dados deste recurso de ocorrência foram publicados como um Darwin Core Archive (DwC-A), que é o formato padronizado para compartilhamento de dados de biodiversidade como um conjunto de uma ou mais tabelas de dados. A tabela de dados do núcleo contém 3.359.932 registros.
Também existem 1 tabelas de dados de extensão. Um registro de extensão fornece informações adicionais sobre um registro do núcleo. O número de registros em cada tabela de dados de extensão é ilustrado abaixo.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Métodos de Amostragem
Phytoplankton was collected through filtration or from sample deposits, data originate from 3,100 sampling points. Diatoms were scraped from hard surfaces fro around 2,600 sampling points. Macrophyte sampling focused on vascular plants using a variety of sampling protocols (Tansley, Braun-Branquet, etc.), there are data from 13,000 sampling points. The intensity of zooplankton sampling was relatively low and restricted to 600 sampling points. Macro fauna sampling was done with nets covering standard plots of about 5 meters and with several additional methods, all together 10,600 sampling points were covered.
| Área de Estudo | Systematic and project based sampling of biotic and a-biotic characteristics of Dutch waterbodies for water management purposes. Data originate from over 20,000 measure points, mainly situated in freshwater inland systems. |
|---|---|
| Controle de Qualidade | Taxonomic names have been validated against the standardised list of Dutch Freshwater Species (Dutch acronym TWN). |
