Web1 jan. 2008 · The magnetic seafloor anomalies in the survey area strike approximately north–south almost parallel to the main field, resulting in very low anomaly amplitudes which had hindered detailed anomaly identification so far. Web6 dec. 2024 · What are marine magnetic anomalies? An alteration in the strength of the Earth's magnetic field brought on by the magnetism of ocean floor rocks is known as a marine magnetic anomaly. Typically, marine magnetic anomalies make up 1% of the total geomagnetic field strength.
