Acquisition - Transition Zone & Marine

 

Transition Zone and Marine Acquisition Solutions

 

Global Geophysical Services provides experienced worldwide ocean bottom nodal operations, through the transition zone and across the sea floor.

 

Our Marine Expertise

 

Marine Innovation: We provide innovative high-density, long-offset, rich-azimuth survey designs with superior subsurface illumination. We offer an unmatched range of receiver node configurations (1C, 2C, 3C, and 4C) along with innovative anchoring and seafloor coupling solutions to ensure the highest quality data in all transition zone and shallow marine environments.

​

The acquisition of Transition and Ocean Bottom Nodal surveys various source types are required. Global Geophysical Services can deploy explosives as an acoustic source in the shallowest depths, shallow draft source vessels in shallow to medium depths and tuned airgun arrays in the deeper waters.

 

Through our extensive experience and planning we understand the requirements of Node deployment in Transition and Ocean Bottom Nodal surveys and the need for multiple deployment vessels. These vessels and deployment methods vary from small shallow draft manual handling vessels to larger, specialised node handling vessels configured to ensure safe and efficient node deployment and retrieval even in heavily congested marine environments. 

 

State-of-the-art fleet: Our fleet is the industry’s most advanced fleet of specialized recording, airgun source and node handling vessels.

 

Seamless Land-to-Marine: With the latest technology, we acquire seamless surveys from land through the transition zone, and into shallow water.
