ACEDP – River Health & E-flows Brisbane, December 2009
! " Separating background variation from real change! " Reducing the need for extrapolation & interpolation! " Capture events – continuous data collection! " Need to cross ecological scales in data collection (Satellite to ground to satellite)! "Need to dialogue with data collection system – react remotely.! "Build overall confidence in the models & decisions made based on the data.
!" A wireless sensor network “system” ! "“Smart” ! "Distributed ! "Low cost ! "Robust ! "Adaptable ! "Scalable ! "Eco-friendly energy! " New platform for environmentalmonitoring & Management support
! " Taking multidisciplinary approach to produce a new generation of integrated technologies – not a one-man project seamless from data collection to application! " Phased R&D Evolution rather than blue-sky invention Proof of concept to viable product! " Applicable beyond the environments being used for development
Pros:! " Cheap! " Insensitive to acoustic noise! " Low sensitivity to natural obsatclesCons:! " High attenuation at high frequency! " Carrier freq must be ELF/VLF: consequent low bandwidth/ comm speed
