In the last twenty year period, the degraded condition of aquatic environments such as rivers, lakes and coastal marine areas, has drawn the public's attention.
The reclaiming of these environments requires a better understanding of the degradation processes. Furthermore, the efficacy of restoration procedures needs to be checked with the passing of time by means of suitable monitoring systems.
In order to accomplish these purposes, IDRONAUT has developed an automatic in situ monitoring system, able to acquire data at high frequency and making it available in real-time. The system, named BUOY 601/701 PROFILERS, has been developed after 15 years of study and experiment in cooperation with the most important Italian and Swiss research institutes of oceanography, marine biology and limnology.

The core of the monitoring system is the Buoy Controller Module which permits, through the availability of advanced digital and analogue interfaces, the creation of a true interdisciplinary monitoring system.
Furthermore, taking advantage of advanced communication systems like phone (GSM/CDMA) cellular networks or like the GLOBASTAR Satellite networks, reliable and powerful real-time communications to and from the BUOY 601/701 PROFILERS can be achieved.
UP TO NOW MORE THAN 70 BUOY
601/701 PROFILERS HAVE BEEN
INSTALLED ALL OVER THE WORLD
BUOY 601/701 PROFILERS can be moored in position quickly, without special tools; the buoy can be moved easily by towing with a small vessel.
The BUOY 601/701 PROFILER is equipped with: |
|
 |
|
| :: |
The OCEAN SEVEN© 316 CTD multiparameter probe which has been designed for oceanographic application and uses very reliable, accurate and drift-free high quality sensors, associated with an advanced and innovative integrated antifouling system.
|
| :: |
The Buoy Controller Module which contains all the hardware and software to supervise the buoy operations, from the winch movements to the internal diagnostics functions. |
| :: |
The computer-driven motorized winch which is located on the top of the buoy hull that contains the Buoy Controller Module too. |
| :: |
The cellular phone link modules (or UHF radio modem or satellite relay system).
|
|
The motorized winch allows to perform automatic vertical profiles with the OCEAN SEVEN 316 multiparameter probe which measures depth, temperature, conductivity, salinity, dissolved oxygen, pH and oxidation-reduction potential and can interface external sensors or data acquisition system (see the OCEAN SEVEN 316 description).
The standard cable length of the winch is 20 meters of 7 mm or 50 meters of 5 mm polyurethane coaxial armored cable.
