This dataset is related to the employment of the unmanned surface vehicle Wave Glider for the study of sedimentary processes in a shallow sandbank area in the Belgian part of the North Sea. During 22 days, data on surface and water-column currents and turbidity were recorded along 39 loops around an aggregate-extraction site. Correlation with wave and tidal-amplitude data allowed the quantification of current- and wave-induced advection and resuspension, being important background information to assess dredging impacts.
This dataset was submitted together with the paper: Van Lancker, V.; Baeye, M. (2015). Wave glider monitoring of sediment transport and dredge plumes in a shallow marine sandbank environment. PLoS One 10(6): e0128948 dx.doi.org/10.1371/journal.pone.0128948 more
Important anomalies in suspended particulate matter concentrations in the water column suggested dredging-induced overflow of sediments in the near field (i.e., dynamic plume), and settling of finer-grained material in the far field (i.e., passive plume). Capturing the latter is a successful outcome to this experiment, since the location of dispersion and settling of a passive plume is highly dependent on the ruling hydro-meteorological conditions and thus difficult to predict. Deposition of the observed sediment plumes may cause habitat changes in the long-term.
Liquid Robotics (www.liquidr.com) provided the platform and sensors to conduct the experiment. The study design relates to the project MOZ4 (Flemish Authorities, Agency Maritime Services and Coast, Coast, contract 211.177). Data collection and analysis were supported by the ZAGRI contract, a continuous monitoring programme, paid from the revenues of marine aggregate extraction activities. The paper contributes also to the Brain-be project TILES (Transnational and Integrated Long-term marine Exploitation Strategies), subsidised by Belgian Science Policy under contract BR/121/A2/TILES ( www.odnature.be/tiles).
