| dc.description | LiDAR data was captured using a Riegl VZ-400 tripod mounted terrestrial laser scanner. Outside of the tube, the tripod was set up such that the scanner was between 1.5 and 2.5 m tall. Inside the tube the tripod was sometimes as short as 0.5 m. Geometric control was achieved using a pair of Trimble RB GPS antennae, one mounted on the LiDAR scanner (rover) and the other setup as a base station. In outside scans, before taking a LiDAR scan, the VZ-400 would use the GPSs to fix a real time kinematic (RTK) solution for the scanner’s location and then use that position (scan position) as a reference for LiDAR returns. Scan Positions were determined for in-tube scans (where GPS lock is not possible) in post processing by ensuring there was significant overlap between scans taken with GPS information and scans inside the mouth of a tube. Post processing was done using RIScan-Pro version 2 (scanner specific software). Also, in post-processing, overlapping areas of point clouds were merged and inaccuracies in roll, pitch and yaw, were resolved using a multi station adjustment routine and the data were projected in UTM coordinates. All the Magnetic data collected at LBNM was collected using a Gem Systems GSM-19W magnetometer, mounted on an aluminum backpack frame at an elevation of ~2m, at a data point frequency of 2Hz. | en_US |
| dc.description.abstract | Archived are Magnetic and LiDAR data collected at Lava Beds National Monument by the NASA funded TUBEX project (Dr. Kelsey Young – PI) in 2017 and 2018. The archived data are for a paper submitted to a JGR Planets special issue on Exploring Planetary Caves as Windows into Subsurface Geology, Habitability, and Astrology with the title: Field Mapping and Modeling of Terrestrial Lava Tube Magnetic Anomalies as an Analog for Lunar Lava Tube Exploration and Prospecting. We use observed data and detailed magnetic models to understand the practicality of mapping magnetic anomalies to determine lava tube locations and internal geometries within a lava flow. | en_US |
