BOTTILT - Ocean Observatories Initiative

Seafloor High-Resolution Tilt measurements are very precise measurements of seafloor tilt, measured in micro-radians. This high resolution enables the measurement of the “tilting” of the seafloor as it deforms in response to uplifting mantle at the summit of Axial Volcano.

Associated Parameters

Seafloor High-Resolution Corrected Compass Direction (BOTTILT-CCMP). Seafloor High-Resolution Tilt measurements are very precise measurements of seafloor tilt, measured in micro-radians. This high resolution enables the measurement of the “tilting” of the seafloor as it deforms in response to uplifting mantle at the summit of Axial Volcano. This data product is the compass direction of the positive Y-tilt axis (in degrees clockwise from North) after corrections for calibration offsets and magnetic declination. Units: integer degrees.

Seafloor High-Resolution Tilt Magnitude (BOTTILT-TMAG). Seafloor High-Resolution Tilt measurements are very precise measurements of seafloor tilt, measured in micro-radians. This high resolution enables the measurement of the “tilting” of the seafloor as it deforms in response to uplifting mantle at the summit of Axial Volcano. This data product is the magnitude of the seafloor tilt since the last re-leveling of the sensor. Units: microradians

Seafloor High-Resolution Tilt Direction(BOTTILT-TDIR). Seafloor High-Resolution Tilt measurements are very precise measurements of seafloor tilt, measured in micro-radians. This high resolution enables the measurement of the “tilting” of the seafloor as it deforms in response to uplifting mantle at the summit of Axial Volcano. This data product is the corrected direction (in degrees clockwise from North) of the seafloor downward tilt since the last re-leveling of the sensor. Units: integer degrees.
