Advancing Near Surface Geophysics in Anthropogenic Environments

Session ID#: 161009

Session Description:
Use of geophysical methods for large area surveys of the shallow subsurface – ranging from ecological resource studies and archaeological applications to assessing pollution impacts and UXO detection – is becoming commonplace. These developments are aided in part by technological innovations in sensors and sensor platforms and the availability of adaptive, often open-source, processing software that is increasingly equipped to handle large heterogeneous data sets. 

Targeting the upper layers of the subsurface still warrants reliable approaches that account for the abundant and dynamic nature of anthropogenic and environmental processes in this region, which must also meet the required sensitivity to detect subtle geophysical responses in noisy environments.  Targeted responses could be related to nutrient variations, pollutants, or the structural integrity of sediments and structures. Expanding practical applications and methodologies, such as the use of drone-based geophysics, further amplify this need for accuracy and precision.

In this session, we invite contributions that push the boundaries of mapping, characterizing, and understanding the shallow subsurface with geophysical methods. Specific focus lies on dealing with issues of noise in urban and highly modified environments and the development of optimized processing and interpretation schemes. From a ‘hardware’ perspective, we especially welcome the application of new instruments and instrument combinations that are geared towards resolving small (less than tens of meters) and subtle variations in the shallow subsurface.
