REAL sensor platforms transmit data over a 
                         hierarchical, wireless sensor network to bridge 
                         large distances while conserving overall sensor 
                         network power. Data is initially delivered to a 
                         sensor server for storage and relay to remote 
                         servers or grid services for further analysis and 
                         processing to better enable ecological inquiry.
                           
                         Shown in Figure 1a is a sensor cluster 
                         comprising several sensor platforms and a sensor 
                         server.  Each sensor platform (Figure 1b)
                         collects data at pre-programmed times with minimal 
                         site disturbance or regular human intervention.  The
                         platform comprises a pole-mounted 
                         sensor unit (Figure 1c) and a solar 
                         panel coupled
                         with a deep cycle battery for providing power
                         over extended periods.  Acoustic clips are
                         collected by the sensor units and transmitted
                         over a wireless network to a laptop 
                         (sensor server - Figure 1d) in a protected
                         enclosure, for temporary storage and later
                         relay to REAL regional servers for further
                         analysis and processing to facilitate
                         soundscape interpretation.
                         The sensor system described here and others are being
                         regularly improved and enhanced as new technologies
                         become available.
