WAVCIS (wave-current information system) is a state-of-the-art monitoring program to provide oceanographic and meteorological conditions on a real time basis around the Louisiana coast. The collected data supports studies of the barrier island and wetland restoration projects (e.g., CWPPRA), and can be used to assist in decision making during storm threats or oil spill in the Gulf of Mexico.
With the AWAC 2D the researchers are able to look at subtidal exchange flows in a system with direct connection to the coastal ocean.
The fact that the AOS system is easy to use and can be deployed without divers is of great value to the team. This makes it well suited for deployment in areas that are heavily fished or areas with strong flow and deep scouring holes.
Since the AOS offers remote configuration from the web application, they are also able to adjust the sampling frequency in anticipation of tropical storms or strong cold front passages.
The AOS unit controls the sensors and transfers the collected data via satellite.
