Seismic Insight on Basement Structure of the Extinct Mid‐Oceanic Ridge in Canada Basin, Arctic Ocean

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract The most accepted theory for the formation of the Canada Basin is that it was created during 66° rotation of Arctic Alaska around the Euler pole located near the Mackenzie Delta sometime during the Mesozoic. Gravity and magnetic anomaly data are consistent with an extinct mid‐oceanic ridge (MOR) in the central basin.

Levelling aeromagnetic survey data without the need for tie-lines [PDF]

open access: yes, 2015
A new methodology that levels airborne magnetic data without orthogonal tie-lines is presented in this study. The technique utilizes the low-wavenumber content of the flight-line data to construct a smooth representation of the regional field at a scale ...
