Positional accuracy can be supported “Combining PAM and using a Doppler velocity log (DVL) and magnetometers.

Working with Canada-based JASCO geochemical sensing

Applied Sciences, Blue Ocean has been doing passive acoustic monitor- ing (PAM) projects to aid environmental into single surveys will and anthropogenic monitoring during seismic surveys and, it hopes soon, also around offshore wind piling operations be a further step in monitoring. For PAM operations, broad spectrum hydrophones are mounted to the gliders to record low and high fre- understanding the cost quency acoustics from marine life.
