Remote Sensing Techniques

In the spring of 1979 a remote sensing project in East Greenland was commenced, introducing this new method of investigation to Greenland. The aim of the project is to investigate the possibility of using airborne remote sensing in connection with mineral exploration. In the region chosen for investigation (Inset, fig. 35) several mineralisations of different types and ages occur, and the purpose is to find out which remote sensing techniques and data processings are appropriate for detection and reproduction on images ofthese known mineralisations. The region is geologically well known and it is well exposed, vegetation and secondary cover being very limited.

AbstractAirborne remote sensing techniques have been developed for the detection of collapse and subsidence features in chalk and other limestone rocks. The detection of such features in the early stages of an engineering project is of crucial importance if serious geotechnical problems to building construction and public safety are to be avoided. Particular attention is paid to the potential of airborne multispectral scanner (MSS) and thermal infrared (IR) data as a means of detection. Background information is also provided concerning a project to obtain multitemporal thermal IR data over two test sites on the Cretaceous Chalk outcrop of southern England.

AbstractIceberg calving is an efficient mechanism for ice mass loss, and rapidly calving glaciers are often considered to be inherently unstable. However, the physical controls on calving are not well understood. Recent studies hypothesize that the presence of a rigid ice mélange (composed of icebergs, bergy bits, and sea ice) can reduce iceberg calving by providing “backstress” to the terminus. To test this hypothesis we use remote sensing techniques to construct a time series model of calving rate and size and composition of the adjacent ice mélange. We describe a semi-automated routine for expediting the digitization process and illustrate the methods for Helheim Glacier, East Greenland, using 2008 data. Ice velocities of the glacier terminus and ice mélange are derived with feature-tracking software applied to radar imagery, which is successfully tracked year-round. Object-based image analysis (OBIA) is used to inventory icebergs and sea ice within the ice mélange. We find that the model successfully identifies the calving rate and ice mélange response trends associated with seasonal increases in terminus retreat and advance and shows seasonal trends of ice mélange potentially providing seasonal backstress on the glacier terminus.

Remote Sensing Techniques

<p>The application of airborne remote sensing techniques permitted by the Comprehensive Nuclear‑Test‑Ban Treaty (magnetic and gamma survey as well as optical imaging including infrared measurements) is done through the prism of inspection team functionality – a logic which applies equally to air and ground-based techniques. Work undertaken over recent years through modelling and practical testing has aimed to better understand the ability of airborne remote sensing techniques to detect relevant observables under different conditions. This has led to the compilation of a concept of operations document that provides guidance on the application of inspection activities during an On-Site Inspection. As well as highlighting the relative merits of each technique, the document also addresses the relative likelihood a particular airborne technique will return relevant information and will avoid the commitment of resources to missions with little likelihood of success.</p><p>The paper also addresses the approaches which have been taken to streamline the acquisition of airborne remotely sensed data through bespoke installations, the identification of optimal data processing routines to facilitate the production of reports and the fusion of airborne data products with other data gathered during an inspection.</p>
