A python tool for AUV-borne ADCP current data processing

Most Autonomous Underwater Vehicles (AUVs) mount Doppler sensors
to navigate precisely underwater, where the Global Positioning System (GPS) is
unavailable. These sensors -aside of providing accurate AUV velocity with respect
to the ground-, can perform currents profiling, measuring currents along the water
column. It has been shown that currents measurements taken by AUVs are very
close to those taken by bottom-mounted ADCPs and that a 3D approach can yield
differences between both instruments of about 0.07 ms-1, averaging AUV data in 90
second time windows. In this paper we present an OceanServer Iver2 AUV 3D water
currents processing tool, developed in Python 2.7. The tool outputs .csv files for
further data processing/representation as well as plots of the main variables, along
with water currents plots.
