This thesis describes the implementation and evaluation of an adaptive time-domain algorithm for signal enhancement from multiple-sensor observations. The algorithm is first derived as a noncausal time-domain algorithm, then converted into a causal, recursive form. A more computationally efficient gradient-based parameter estimation step is also presented. The results of several experiments using synthetic data are shown. These experiments first illustrate that the algorithm works on data meeting all the assumptions made by the algorithm, then provide a basis for comparing the performance of the algorithm against the performance of a noncausal frequency-domain algorithm solving the same problem. Finally, an evaluation is made of the performance of the simpler gradient-based parameter estimation step.

Forward scattering of a pulsed continuous wave signal through laminar and turbulent thermal plumes Bowen, Stephen G. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1993-09)The results of an experiment examining the forward propagation or an acoustic signal through a buoyant plume are discussed. Two distinct testing sights were used. One made use of a small fresh water tank in NUWC to provide ...
Deciphering isotopic signals of monsoon-induced upwelling in foraminifera from the Western Arabian sea sediment trap Stuart, Dana R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1997-03)Isotopic analyses have been made on four species of foraminifera collected with a PARFLUX Mark VI sediment trap in the Arabian Sea during the 1986 and 1987 monsoons. Two of the species are non-spinose thermocline dwellers ...
