Abstract
Abstract A shallow water environmental/oceanographic measurement system for real time monitoring of specific parameters at a particular location. A three point moored buoy is anchored over the particular location. Bottom mounted sensors to measure the specific parameters are situated generally within the area of the three point mooring area. Sensor data is transmitted via cable to the buoy from where it is telemetered to a shore station.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
192 words
A shallow water environmental/oceanographic measurement system comprising: a moored cylindrical buoy having a central hawse pipe, said cylindrical buoy being anchored at multiple points over a particular location and containing an electronics package; a first pipe mounted on said cylindrical buoy, said first pipe enclosing the upper end of said hawse pipe; a second pipe having a gooseneck at the top, said second pipe being mounted on said cylindrical buoy such that the bottom of said second pipe extends into the interior of said cylindrical buoy and said gooseneck extends over the upper end of said first pipe; a plurality of sensors mounted on the sea floor within the moor area of said cylindrical buoy, said sensors being connected to said electronics package in said cylindrical buoy by electrical cables over which sensor data is transmitted; and means connected to said electronics package for transmitting said sensor data to a remote site, said transmitting means being mounted on said cylindrical buoy; whereby said electrical cables from said sensors are routed through said hawse pipe, said first pipe and said second pipe to said electronics package in the interior of said cylindrical buoy.
