Description

Basic information

Dataset title	ZooImage training set, northern Baltic zooplankton
Theme	Biology and Ecology
Description	A small training set for ZooImage program: scanned zooplankton images, grouped into taxonomic / functional groups. The zooplankton have been collected as part of the COMBINE monitoring programme in the open sea areas of the Gulf of Finland. An article based on the data is published and can be found at https://doi.org/10.1016/j.ecolind.2016.05.036
Language (dataset)	English
Keyword	Baltic Sea, zooplankton, plankton, images, ZooImage

Data processing steps

Data processing steps	sampling
Description	The samples were collected in August from the surface layer, during regular monitoring cruises on R/V Aranda from the Gulf of Finland, northern Baltic Sea, using a vertically towed 100 micro-m mesh sized WP-2 closing plankton net (Hydrobios, Kiel, Germany). Samples were preserved immediately after collection with 4% formaldehyde solution (Harris et al., 2000) until analysis in the laboratory.

Data processing steps

processing

Description

Before scanning, samples were dyed overnight using eosin to enhance contrast (Harris et al., 2000) and applied thinly, so that the zooplankton individuals were mostly separate from each other on a clear, transparent plastic tray (the lid of a PCR plate). Sixteen samples were scanned two at the time using an Epson PerfectionV750 scanner at 2800 dpi resolution,meaning that the length of 1 mm includes approximately 110 pixels in the image. The pictures (examples in Fig. 2) were scanned as colour pictures and analysed using colour picture algorithm. For the training set, 81 subsamples were scanned, and a total of 1446 scanned images (zooplankton individuals and inanimate objects) of were included.
