| 41. | The continuity is evident in structural maps of basement rocks, in magnetic surveys, and in free air gravity field surveys.
|
| 42. | Its five remote-sensing instruments are designed to map the composition of the lunar surface and observe its magnetic and gravity fields.
|
| 43. | By measuring the change in distance between the two spacecraft, the gravity field and geological structure of the Moon was obtained.
|
| 44. | Due to variations in the density and types of materials that make up the Earth, its resulting gravity field is lumpy.
|
| 45. | This gravity field includes mean anomaly values compiled directly from observed gravity data wherever the latter was available in sufficient quantity.
|
| 46. | His aim was to develop hypothesis-free methods for determining both the gravity field and defining vertical reference systems for large areas.
|
| 47. | Gravity measurements in the 1960s showed an abrupt shift in gravity fields across Seattle, Pratt said, which hinted at a fault.
|
| 48. | The changing gravity field can be detected by repeated land measurements with absolute gravimeters and recently by the GRACE satellite mission.
|
| 49. | A depression in the water can be supported by a variable gravity field, as occurs now in locations of low tide.
|
| 50. | Ryan tells Barnaby to head into a narrow pass where Ryan vertically extends his gravity field to neutralize Kasha as she follows.
