Abstract
Current pace of ocean resources exploitation have set the alarm for tighter environmental monitoring.
Recent European legislation requires very accurate measurements of reference values for all types of
ocean pollution, including acoustic noise. For near shore or offshore construction, platforms or
infrastructures extensive measurements should be carried out before during and after exploitation
activities have taken place. Environmental monitoring requires the deployment of sensors with specific
requirements in terms of location, spatial coverage and data access rates. In some cases, monitoring
includes accessing real time information regarding detecting intruders, their localization and, eventually,
their interception. A key component of any environmental monitoring network is a high performance wireless
communication network capable or interconnecting both fixed and moving sensing platforms for retrieving
data and transmitting commands. The Underwater Acoustic Network initiative has recently demonstrated with
an at sea experiment (Trondheim, May 2011) a full functioning 3 fixed node and 2 mobile node network
for collecting data and performing surveillance tasks. A summary of the results are presented and issues
discussed.
