Ojeda Ingeniería Colombia gas hydrate heat transfer Caribbean area bottom simulating reflector (BSR) Geothermal heat flow in gas hydrate zones can be determined theoretically from the Bottom-SimulatingReflector. A Bottom-Simulating Reflector (BSR) has been observed in multichannel seismic datafrom the Caribbean offshore Colombia. This anomalous reflector, known to correspond with thebase of the Gas Hydrate Stability Zone (GHSZ), can be used to estimate a range of possible values for thelocal heat flow using the stability field of gas hydrates and the thermal conductivity of the sediments. Thestudy area extends from northern Guajira in the north to the Gulf of Uraba in the south, covering some18 000 km2. The heat flow was found to be 27,6 ± 4 mW/m2 off the coast of Barranquilla, 37,9 ± 3,6mW/m2 for northern Guajira, 33,2 ± 5,5 mW/m2 for the central Guajira and 34,7 ± 9,4 mW/m2 for theCartagena Gulf of Uraba offshore areas. These results are comparable to heat flow estimates of 30 and42 mW/m2 obtained for the south Caribbean by others using alternate methods. The estimated heat flow isrelatively low in relation to other continental margins. The continuous and fast sedimentation rate from theMagdalena River may explain the anomalously low heat flow in the river delta area.
