Temperature and resistivity profile of drill hole CRP-2A
In the northern part of McMurdo Sound (Ross Sea, Antarctica), drillhole CRP-2/2A targeted he western margin of the Victoria Land basin to investigate Neogene to Palaeogene climatic and tectonic history by obtaining continuous core and downhole logs. The background of the project and its detailed aim...

The CRP-2A drillhole extended to 625 mbsf (meters below seafloor) with an average of 95 % recovery of Oligocene to Quaternary sediments.
