Abstract Suspended Particulate Matter (SPM) concentration profiles of the lowest 2 m water column and particle size distribution at above bed were measured in a coastal turbidity maximum area (southern North Sea) during more than 700 days between 2006 2013. The long‐term data series SPM concentration, floc size, settling velocity have been ensemble averaged according to tidal range, alongshore residual flow direction, season, order investigate seasonal dynamics its relation with physical...
The suspended particulate matter (SPM) concentration in the high turbidity zones of southern North Sea is inversely correlated with chlorophyll (Chl) concentration. During winter, SPM and Chl low vice versa during summer. This seasonality has often been associated seasonal pattern wind forcing. However, decrease corresponds well spring algal bloom. Does caused by changing conditions cause start algae bloom, or does bloom concentrations through enhanced flocculation deposition? To answer...
Predictability of the dispersion sediment plumes induced by potential deep-sea mining activities is still very limited due to operational limitations on in-situ observations required for a thorough validation and calibration numerical models. Here we report plume experiment carried out in German license area exploration polymetallic nodules northeastern tropical Pacific Ocean 4,200 m water depth. The small-scale dredge April 2019 was investigated numerically employing transport module...
The abyssal seafloor in the Clarion-Clipperton Zone (CCZ) NE Pacific hosts largest abundance of polymetallic nodules deep sea and is being targeted as an area for potential deep-sea mining. During nodule mining, sediment will be brought into suspension by mining equipment, resulting formation plumes, which affect benthic pelagic life not naturally adapted to any major transport deposition events. To improve our understanding plume dispersion support development models this specific area, we...
Three experiments were conducted in the Belgian part of North Sea to investigate short-term variation seafloor backscatter strength (BS) obtained with multibeam echosounders (MBES). Measurements acquired on predominantly gravelly (offshore) and sandy muddy (nearshore) areas. Kongsberg EM3002 EM2040 dual MBES used carry out repeated 300-kHz measurements over tidal cycles (~13 h). analysed complement an array ground-truth variables sediment current nature dynamics. Seafloor water-column...
As human pressure on the marine environment increases, safeguarding healthy and productive seas increasingly necessitates integrated, time- cost-effective environmental monitoring. Employment of a Wave Glider proved very useful for study sediment transport in shallow sandbank area Belgian part North Sea. During 22 days, data surface water-column currents turbidity were recorded along 39 loops around an aggregate-extraction site. Correlation with wave tidal-amplitude allowed quantification...
The purpose of the study was to measure in situ background suspended particulate matter concentration (SPMC) DISCOL area (SE Pacific) and its increase due mechanical mobilization seabed. disturbance experiment imitated future manganese nodule exploitations designed sediment plume generated by such activities. In direct vicinity disturbance, landers equipped with acoustic optical sensors measured current velocities SPMC. SPMC at easily up 10 mg/L thus about 200 times higher than...
