In spite of all the technological progress we have witnessed over the past few decades, we still know very little about the physical and biological activities taking place underneath the Ocean surface. To learn more about this hidden realm, researchers use autonomous probes or tags attached to larger aquatic animals that collect a variety of environmental data such as water temperature, pressure, salinity, oxygen content, etc. The processed data contribute to a better understanding of flow rates of deep Ocean currents (heat flux for climate models) or migration paths and feeding habits of aquatic animals.
This talk concentrates on the design and implementation of a small archival tag that records temperature, pressure and position using acoustic tracking. With a length of 4.5 cm and a weight of 7 g, the novel tag can readily be attached to small fish or other aquatic creature of interest (e.g. lobsters or sea turtles). The functionality of the tag has been demonstrated through a field test conducted in the Gulf of Mexico.
Dr. Fischer earned his Ph.D. in Electrical Engineering from the Swiss Federal Institute of Technology, Zürich, Switzerland, in 1985. Since then, he has been a professor in the department of Electrical, Computer and Biomedical Engineering at the University of Rhode Island. His research interests are in the field in mixed-signal integrated circuits, in particular low power CMOS circuits.
