Paleomagnetic measurements
WebDec 19, 2014 · During the measurements described here, the temperature of the gyros stayed in a range of 30°C to 48°C (Site U1374, duration of the measurement: 427 min) and 28.5°C to 43°C (Site U1376, duration of the measurement: 274 min). Some variance in the temperature cannot be avoided, as the water temperature was as low as about 2°C. WebJul 8, 2016 · Continuous measurements on pass-through SRMs, however, are subjected to smoothing and distortion due to the convolution of sensor responses, controlled by the geometry of pick-up coils and superconducting shield, with the magnetization of paleomagnetic sample (e.g., Shibuya and Michikawa 2000; Oda and Xuan 2014).
