This report proposes a new mode for oceanic observations that can be conducted to "one buoy per fisherman". In response to requests from the scallop cultivation fishermen, a new personal buoy based on sensor network technologies has been developed at a price of approximately US$ 1,000 each for seawater temperature observations. The network currently being developed for use by individual...
The multi-beam echo sounder system with an accurate GPS can provide a detailed view of the seafloor and is successfully utilized in oceanography but its expense makes it impractical for many uses. The authors have therefore presented a low-cost system for surveying shallow sea bottom topography by using a fishing echo sounder in such a way that the many areas of the industry in which the information...
In this paper, the authors present a compact buoy system used to observe seawater temperatures for scallop cultivation. The system is based on the sensor network technology, namely Micro Cube, which makes it possible to collect seawater temperatures from thermometers via the Internet. Thermometers adopted with a multi-drop interface for measuring the multi-layer seawater temperatures were also developed...
