Gravity Measurements in the Beaufort Sea Area
Reports investigations on Ice Island T-3 at approx 70-80 de- grees N, 110-140 degrees W, May 1958-Sept 1959. The North American 113a and Worden E-340 gravity meters were used for twice- daily measurements. Values of observed gravity, free air and Bouguer anomalies are tabulated, contoured, and inter...

Summary: | Reports investigations on Ice Island T-3 at approx 70-80 de- grees N, 110-140 degrees W, May 1958-Sept 1959. The North American 113a and Worden E-340 gravity meters were used for twice- daily measurements. Values of observed gravity, free air and Bouguer anomalies are tabulated, contoured, and interpreted. Gravity anomalies were found at 76-80 degrees N, and a gradient near 75 degrees N which indicates an increase in density of subbottom rocks toward the southwest. Bouguer anomaly values increased with distance from land, characteristic of normal ocean basins. |
