Seabed Mapping for Coastal Engineering


A-2-Sea’s survey capability is specially tailored towards the provision of survey services in the near-shore environment.

Ultra-high resolution shallow water multibeam echo sounders and side scan sonars are used to conduct baseline and reconnaissance surveys for a variety of nearshore survey applications.

A-2-Sea offers a range of topographic and shore-based surveys including beach-profiling and laser scanning to assist with coastal engineering projects. To discuss project requirements or for information on survey vessels, please call us on 01794 830909 or email us.

The latest generation marine magnetometers and gradiometers are used to detect potential unexploded ordinance (UXO) for coastal engineering projects.

In addition to its core activities, A-2-Sea offers oceanographic services including tide, wave and turbidity monitoring.

A shallow-draft dedicated in-house survey vessel (12-hr and 24-hr capability) provides the ideal survey platform to conduct nearshore survey operations. Alternative survey platforms (draft <0.5m) are available to acquire data to overlap with any land survey elements.

A-2-Sea’s survey professionals specialise in surveying the near-shore environment and appreciate the dynamic nature of the land-sea interface and its implications on coastal defence and engineering projects.
