Processed magnetometer data acquired near-bottom along the frontal thrust of the Cascadia Margin with MBARI's Mapping AUV (MAUV1)

This magnetometer data was collected with a WHOI-style Applied Physics Systems model 1540 3-axis fluxgate sensor mounted in the mid-body of the vehicle on MBARI' Mapping AUV (MAUV1) on mission 20230817m1. The data file is in ASCII tab-separated format and has 15 columns, with column headers. The file contains data collected during the near-bottom survey only and not during the descent or ascent. The data includes merged processed magnetometer, navigation, attitude and altitude data using the processed multibeam sonar data. Columns labeled mx_G my_G mz_G are the processed magnetic values in the X,Y,Z directions; the units are Gauss (1 Gauss = 100,000 nT). The AUV survey missions were conducted during R/V Rachel Carson cruises along the Cascadia Margin. Data were acquired as part of a collaborative research project between MBARI and the U.S. Geological Survey. Funding for the AUV mapping was provided from the David and Lucile Packard Foundation.
