Figure F15. Plot of results from a comparative test of the JOIDES Resolution’s superconducting rock magnetometer (SRM) filters using a sample core section of concrete materials. The concrete in the sample core section starts after an interval of ~0.38 m (unshaded region). The interval without sample near the sample end (~0.38 m) revealed strong signal because the sensor coils of the SRM have a ~20 cm corresponsive region.
