Current meter mooring. This is a fixed mooring that can accommodate many instruments, including current meters, temperature and salinity recorders, and chlorophyll measurement devices (fluorometers). These are arranged at predetermined depths, and a sub-surface buoy and elastic tether keep the wire taut. The surface buoy transmits data to land via satellites; radar reflectors and lights help to prevent collisions from ships.
These buoys store information from the attached instruments and also let ships know there are instruments in the water. Data from the buoy are transmitted via satellite to a ground station where the information is stored in computers. Scientists can log into the computer, also by satellite on land or from the ship, and download the information. The satellite passes over the buoy twice per day. Many of these buoys are kept in place for about a year, which allows for remote monitoring of the bank.
