Dataset identification

Title of datasetOceaneye’s microlitter data 2011-2020
Narrative summary of datasetThis dataset is a compilation off all sea surface micro- and mesolitter data produced by Oceaneye between 2011 and 2020 during several volunteer monitoring expeditions with the use of manta nets. The dataset provides in-depth information such as station location, date, time, sampling distance and wind speed, but also number and mass of items for the different categories.
Summary of processing methodologySamples were collected with manta nets (mesh size = 0.33 mm) from different sailboats at a target speed of 1.5 m/s and in wind conditions between 0 and 10.3 m/s. The duration of the trawl ranged from 30 to 90 min. The distance covered was evaluated by the GPS distance or with a mechanical flow meter. The wind speed was measured for each sample with an anemometer placed at the top of the mast. Samples were first sieved through 5 mm, 1 mm and 300 µm sieves, to separate mesoparticles from bigger and smaller microparticles, and rinsed with water. All particles were visually identified with a stereo microscope, separated from the plankton and sorted into six form categories. Once dried for one week at ambient temperature, the particles of each category were counted and weighted. More info at :
