|Mapping Sediment Contamination with a Gamma-Ray Spectrometer, Underwater and on Land|
Environmental contamination due to human activity is recognized as one of the modern dangers of our industrial advancements. At present, there are no means for the passive, in-situ mapping of contaminants in aquatic and non-aquatic sediments. As a result, a proper risk assessment of sediment contaminant levels is often overtly expensive or lacks proper data.
Our method addresses the main problems associated with the current approach. We propose a method that provide rapid, spatially detailed data on contaminant distributions and concentrations in sediments by using a gamma-ray spectrometer. A gamma-ray spectrometer can be used for mapping aquatic sediments (by using a vessel as platform) and non-aquatic sediments as floodplains by using a quad-bike or drone as platform for the sensors.

An Underwater Gamma Spectrometer as Tool for Ecological Assessment
In recent years, laws ands regulations in the field of ecology became more strict due to public pressure. Therefore, the discharge of fines during dredging and land reclamation works and its impact on seafloor habitats is an important aspect in environmental impact assessments.
We describe an approach in which an underwater gamma spectrometer can be used to quantitatively map the concentration of fines in sediments. With this approach, the natural variation of fines and thereby the buffering capacity of the seafloor can be monitored and the natural dynamics due to re-suspension and large-scale sediment transport patterns can be quantified. The information derived from the geophysical measurements give the opportunity to measure the effects of human induced projects at sea.
