Geophysics and Mapping Platform

The GeMaP is a service offered by the NRF and as such the NRF has the right to alter the required operational rules as and when required. These changes will not apply retrospectively on any data agreements. The platform is provided on a competitive basis. 

​

The Reson SeaBat™ 7101 system covers a 150° (maximum) across track swath with a transmit beam (Tx) of 1.5° along track. The Receive beam (Rx) covers 15° along track; 101 1.5° x 1.5° beams (= 511 beams). Typical operating depths range from 20 to 350 m, however, resolution and backscatter intensity will degrade with depth. Similarly, swath width will be experience a reduction beyond 125 m depth. For typical operations along track coverage of 2-3 x water depth should be anticipated. Weather conditions, vessel speed, bottom type and topography will all impact swath width and data quality. The Valeport SWIFT SVP will cover the full depth profile of the Reson SeaBat™ 7101 under normal operating conditions.
