To meet the requirements of shallow water where normal photography is near impossible, Gardline Environmental has developed the Freshwater Lens camera system for non-intrusive sampling and habitat mapping.
The Piston corer takes between 3 and 8 metres of undisturbed samples from soft and/or muddy sediment.
Gardline Geosciences has two wireline cpt systems capable of working into waterdepths up to 600 metres. The wireline CPT can be deployed through its own drill string as well work from third party drill rigs.
The Cone Penetration Test is based on pushing an instrumented cone into the ground at a constant speed, with continuous measurement of the cone end resistance, the friction along the sleeve of the cone, and the pore water pressure.
The Neptune cpt systems use a coiled rod system. This system limits the depth below ground level that can be reached but it is easier to deploy form a variety of vessels. Neptune 3000 system weighs 3 tonnes and has a 10 metre rod. The system uses 2 and 5 cm2 cones.

The GL 75 drill rig is a fully heave compensated drill rig capable of drilling in waterdepths of up to 400 metres. Gardline Geosciences has acquired the rig in January 2008 and has carried out drilling work for the oil and gas and windfarm industry in the North Sea, Irish Sea and of West Africa.
