The monitoring of threatened and endangered aquatic species in remote streams and rivers requires frequent and accurate surveys at a variety of locations and times, in order to protect and enhance the viability of tenuous populations. Present methods of aquatic life monitoring require large manpower investments and equipment expenditures, yet offer only modest data quality. May 2005, the United States Department of Angriculture, Forest Service, launched a call for the development and testing of equipment that can be used to directly detect, measure the size of, and/or differentiate the species of fish and/or other aquatic species, in their natural habitats, without manual intervention. The ETRO-IRIS research group joint forces with Sensatech Research Ltd, to participate in this call, and won a $240.000 USD research contract to develop and test a new system for aquatic life monitoring based upon the principles of Electrical Capacitance Tomography. Electrical Capacitance Tomography (ECT) seeks to reconstruct internal distribution of electrical impedance contrast from the measurement of the boundary potentials arising from passing an AC current through an object. Sensatech Research Ltd has a long standing tradition in the development of capacitive sensing technologies, and will be involved in the design of a new 2D capacitive sensing array. ETRO-IRIS will contribute its most recent research results on the derivation of a new class of subspace based structured problem formulations for the solution of ill-posed nonlinear inverse problems such as that of ECT.
