PROOCEANO & GLIDERS: TIMELINE
PROOCEANO & GLIDERS R&D | Project Azul | Petrobras Glider/Wave Glider Data Collection Monitoring Service | Acoustic Monitoring
PROJETO AZUL http://projetoazul.eco.br Pilot program for Santos Basin/Brasil 1. continuous 3-D data collection; 2. near real-time data for data assimilation; 3. public database for academy & industry; Funded by BG-Brasil (Shell now) Performed by PROOCEANO and UFRJ
Glider Objectives to increase sampling a)longer campaigns; b)any weather/wave condition; c)greater spatial coverage; to reduce costs and risks of traditional ship- based observations;
Projeto AZUL 14

ACOUSTIC MONITORING WITH GLIDERS • Increasing marine economic activities are likely to increase anthropogenic noise input in the ocean; • Lack of knowledge of present state and potential impacts; • Recent environmental concern put pressure on governments to regulate activities with potential impacts; • European Commission Monitoring Guidance for Underwater Noise (DEKELING et al. 2014) 35
ACOUSTIC MONITORING WITH GLIDERS • Santos Basin Passive Acoustic Monitoring • Obtaining the Soundscape of the area before the activity reaches maturity level in the region; • Profilers and Gliders; • 2 years of continuous data collection 36
