Distribution of blue and sei whale vocalizations, and temperature - salinity characteristics from glider surveys in the Northern Chilean Patagonia mega-estuarine system

Northern Chilean Patagonia is a mega-estuarine system where oceanic waters mix with freshwater inputs in the coastal fjords, channels and gulfs.The aim of this study was to examine the distribution of blue and sei whales with respect to oceanographic conditions of the study area from the estuarine inner sea to the outer ocean.Ocean gliders were use

Fault diagnosis of AUV based on sliding-mode observer

Designing of a sliding mode Tea Tree observer was finished based on the motion model of autonomous underwater vehicle (AUV).A Flutter decrease strategy for the sliding mode observer was discussed and the sliding mode observer was applied to the fault diagnosis of the AUV.Simulation experiment without faults was designed.Simulation experiment of sen
