Hyperspectral reflectance dataset of dry, wet and submerged marine litter

Abstract. This paper describes a dataset consisting of 47 hyperspectral reflectance measurements of plastic litter samples. The plastic litter samples include virgin and real samples from the Port of Antwerp. They were measured in dry conditions in the VITO calibration facility and a selection of the samples was also measured in wet conditions and submerged in a watertank at Flanders Hydraulics. The construction on top of the tank allowed to submerge the plastics and keep sediments in suspension. The spectral measurements were performed using an Analytical Spectral Devices (ASD) FieldSpec 4 and a Spectral Evolution (SEV) spectrometer. The datasets are available on the 4TU.ResearchData open-access repository (ASD dataset: https://doi.org/10.4121/12896312.v2, Knaeps et al., 2020; SEV dataset: https://doi.org/10.4121/uuid:9ee3be54-9132-415a-aaf2-c7fbf32d2199, Garaba et al., 2020).
