Full integrated underwater experiments in 200 meter deep water 
As the final experiment, CLAM consortium performed a two weeks tests in 200 meter deep water in Trondheim, Norway. The objective of these tests, taking place in the period of 20 May 2013 - 01 June 2013, was to evaluate the integration of sensing and communication platform and networking, localization, and situation awareness techniques in a full functional underwater wireless sensor network.

Interviews with Wouter van Kleunen about underwater localization  
Following the successful underwater localization experiments performed in Het Rutbeek lake, interviews with Wouter van Kleunen were published on UT and Kennis Link websites. He was also interviewed by Enschede FM radio. The localization experiments are part of STW SeaSTAR project on underwater monitoring platforms.

SeaSTAR underwater experiments in Het Rutbeek lake 
The Dutch SeaSTAR project, which is funded by Technology Foundation STW, has reached a new milestone on May 6th 2013, when a network consisting of custom-built underwater sensor nodes was deployed and tested by the Pervasive Systems group of the University of Twente. In total, seven underwater nodes, were deployed in a lake at the Rutbeek recreational center near Enschede, The Netherlands. The goal of the test was to assess the feasibility of autonomous localization of the sensor nodes.

Autonomous localization of underwater sensor nodes is of great importance when such networks are used to monitor water quality, marine life behavior, oil spills, underwater pipeline integrity, and other underwater structures. Our tests show that autonomous localization is indeed possible.

The sensor nodes were developed in-house by the group with low-cost and flexibility in mind. Costs were kept down by using a COTS CPU board and standard PVC materials, whereas flexibility was achieved by implementing most features, such as the underwater MODEM and localization algorithms, in software.
