Sea survey services
Some projects start on land and continue into the water, some go the other way round.
Geophysics on water is something that really can be more efficient than other more direct methods of investigation. Getting a drill-rig out on the sea is a major operation, using geophysics deployed from a boat is most often considerably less complicated.
Using the same geophysical firm for both the land and sea part of a survey can really add benifits for your project. This makes sure that the surveys match up and a smooth transition between the surveys is assured.
