This study presents magnetic anomaly data from a new high-resolution, low-altitude helicopter-borne magnetic survey
 recently collected on and offshore Tenerife in the Canary Archipelago. The Italian Istituto Nazionale di Geofisica
 e Vulcanologia (INGV) in collaboration with the Museo Nacional de Ciencias Naturales of the CSIC of Spain
 conducted the survey in 2006. The data for Tenerife and surrounding marine areas were processed into digital total
 intensity magnetic anomalies for geomagnetic epoch 2006.4. Relative to previously available higher altitude
 magnetic survey data, the new survey mapped higher resolution anomalies with significantly improved spatial details,
 especially over the Las Cañadas caldera and Teide-Pico Viejo complex in the central part of the island. A good
 correlation is evident between known structural geology and the magnetic anomalies, where the new shorter wavelength
 anomalies facilitate more detailed and comprehensive geologic interpretations.
