Title:

2015 AUV Sentry vehicle-corrected navigation and raw magnetic sensor data, Axial Seamount

Abstract:

This data set consists of raw magnetic field measurements and vehicle-corrected navigation for autonomous underwater vehicle (AUV) Sentry dives over Axial Seamount, Juan de Fuca Ridge collected in 2015 during research cruise TN327 on R/V Thomas Thompson. AUV Sentry is operated as part of National Deep Submergence Facility (NDSF) by Woods Hole Oceanographic Institution (WHOI) and is funded by the National Science Foundation (NSF). The AUV Sentry magnetometer is an APS (Applied Physics Systems) model 1540 3-axis fluxgate sensor (https://www.appliedphysics.com/products/magnetometers/). AUV Sentry has three magnetometer sensors, two are located mid-body on the port and starboard side and one is located in the top of the vehicle. These data files contain raw magnetic field data from the 'top' sensor which is also identified as the '02' sensor. Navigation is by USBL.The data files are in ASCII format with the following columns: year, month, day, hour, min, sec, latitude (dec. degrees), longitude (dec. degrees), depth (meters), pressure (decibars), heading (degrees), altitude (meters), mag02x (nT), mag02y (nT), mag02z (nT), optical backscatter sensor OBS (volts), redox potential eh (volts), rate of change of redox potential dehdt (volts/second), oxygen O2 (micromolar), temperature (celsius), conductivity (siemens/meter), sound speed (meters/second), sound velocity profile SVP (meters/second), oxygen reduction potential (volts). The data set was collected under grant OCE13-56839 from the National Science Foundation. The AUV Sentry magnetic data were analyzed and interpreted under a Woods Hole Oceanographic Institution (WHOI) internal research grant to Maurice Tivey and with additional support for Bailey Fluegel by the WHOI Summer Student Fellow program in 2021. The data set is described in Fluegel et al., GRL, 2022.
