Bias correction and uncertainty characterization of Dead-Reckoned paths of marine mammals

摘要: Background Biologgers incorporating triaxial magnetometers and accelerometers can record animal movements at infra-second frequencies. Such data allow the Dead-Reckoned (DR) path of an to be reconstructed high resolution. However, poor measures speed, undocumented caused by ocean currents, confounding between movement gravitational acceleration measurement error in sensors, limits accuracy precision DR paths. The conventional method for calculating paths attempts reduce random errors systematic biases using GPS observations without rigorous statistical justification or quantification uncertainty derived swimming
