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;

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)

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
