We present findings from a choice experiment investigating improvements in the aquatic environment from mitigation of barriers to fish passage. Implemented at a local and national level, results reveal positive preferences for increased numbers of fish species as well as fish abundance. In addition, we examine if in this case the willingness to pay estimates are suitable for direct transfer bet...
This paper reviews the existing localization techniques and parameters in Wireless Sensor Networks (WSNs) and few schemes are discussed in term of Terrestrial WSNs. The fundamental differences between Underwater and Terrestrial WSN are highlighted. Furthermore, the paper analyzes the few existing aquatic localization schemes and presents a discussion in two parts including general localization ...
We present a low-cost sensor buoy designed for unattended dissolved oxygen measurement in aquatic environment. We describe the buoy’s architectural design and three experiments that we carried out to demonstrate its viability: a laboratory test in a water tank with controlled oxygen level, a lake deployment and an extensive electric power consumption test. Our experiments indicate the viability...
