TDI-Brooks have been awarded a surface geochemical exploration program (SGE) in deepwater blocks off Colombia. The program will include acquisition and analyses of 105 piston cores in COL-1, 2, 6 and 7 in 3,700 to 4,100m water depth.
TDI-Brooks has a long-history of conducting (SGE) coring programs in Colombia as shown in Figure 1 . TDI-Brooks has acquired several thousand cores in Colombia over the last 20+ years.
TDI-Brooks has two (2) multi-use oceanographic research vessels that are outfitted to acquire cores out to 4,000 meters water depth. These are the R/V GYRE and R/V PROTEUS. For this project, they will be using the R/V GYRE with fieldwork expected in 2Q of 2023.
The R/V GYRE is outfitted with a full seep hunting kit including a newly installed Kongsberg EM-304 (1x1) hull-mounted multibeam (MBES) kit and Edgetech HM3300 Chirp subbottom profiler with a 4x4 Masa TR-1075 transducer array. The vessel has geotechnical and geochemical coring, heat flow, CPT and other sampling capabilities. The GYRE has conducted over the last several years two (2) large wide area MBES/backscatter/plume detection projects for TGS for their MSGBC (Senegal, Gambia and GB) and Nigeria multi-client seep hunting projects (see Figure 2). These programs involved ~200,000 km2 of MBES acquisition and hundreds of cores and heat flow (HF) acquisitions. The GYRE is outfitted with TDI-Brooks’ full coring kit with USBL positioning along with heat flow probes.
