 In January 1914 , Detzner travelled to Rabaul on New Pomerania ( now New Britain ) . In February , he began his expedition into Kaiser @-@ Wilhelmsland . His survey immediately revealed inaccuracies in the 1909 joint survey ; by March , Detzner had concluded that the border corridor was already showing a discrepancy of more than 650 meters ( 2 @,@ 133 ft ) from the 8 ° 0'S parallel . The discrepancy increased the further west he traveled , revealing a widening wedge in the boundary as it was agreed upon , and as it was marked . The discrepancy favored German interests .
