? ngerprinting and multiple hydrophones to gain directionality alongside real time PAM processing capabilities.” The ? rm is already deploying single Smooth, Easygliders ? tted with multiple hydrophones, to aid in understanding the directional-Ship Repairsity of acoustic signals to be ascertained. Start Here!The next step is to use multiple gliders ? tted with hydrophones that are tracked with USBL systems to provide far wider area coverage, with greater accuracy directionality, and capable of providing more accuracy around noise source geo-location. Blue Ocean is looking to trial this system in 2019. For offshore wind construction opera-tions, Blue Ocean is looking at taking On-Time • In Budgettake part in a pilot study, to understand piling operations from a remote, dynam-ic platform and monitor marine mammal Top Quality • Safety Focusedactivity before during and after these events. The proof-of-concept study is due to take place in Europe with a large-scale offshore wind operator. “Combin-ing PAM and geochemical sensing into www.detyens.comsingle surveys will be a further step in understanding the cost bene? ts associ-ated with this type of force multiplier,” says Lind. Blue Ocean is also working on integrat-ing JASCO’s OceanObserver system, which would enable a modicum of real time data processing on board the glider. “As stands, processing for PAM data on board a glider platform can involve some 375,000 samples per second,” says Lind, “which is a lot of number crunch-ing. With this software, some of the pro-cessing can be carried out on board the Glider, enabling real-time detection of marine mammals for instance.”The ? rm also has a number of studies due to take place in Europe and further a? eld by the end of this year, involv-ing PAM and ? uorometer measurement campaigns.www.marinetechnologynews.comMarine Technology Reporter 41MTR #8 (34-49).indd 41 MTR #8 (34-49).indd 41 9/28/2018 2:58:27 PM9/28/2018 2:58:27 PM
