Detailed aeromagnetic survey point data of the Trinidad Area, California

Description

This data release provides access to point measurement data from a low-altitude, aeromagnetic survey of a part of northwestern California. The survey extends west of the Klamath Mountains across the Pacific Ocean coastline over the continental shelf and covers the towns of Crescent City, Trinidad, Fortuna, Eureka, Arcata, and McKinleyville. Data were acquired during the summer and fall of 2024 by Xcalibur Multiphysics working under contract to the Yurok Tribe and under supervision of the U.S. Geological Survey. Total magnetic field values were acquired using a fixed-wing aircraft flown at a target elevation of 305 meters (m) above terrain and along flight lines and tie lines spaced 600 m and 6000 m apart, respectively. Flight lines were directed northeast-southwest; tie lines were directed northwest-southeast. A total of 13,134 line-kilometers were acquired.
