Argos in the Field: Anchor Discovered in 2019

Magnetic Map. Raw data collected by a boat-towed magnetometer survey reveals complex anomaly shapes that can be difficult to interpret and identify where source objects are located.

Gradient Map. The computed Analytic Signal or Total Gradient of the same area illustrates a clearly identified target region, but in a region that may be many meters in diameter.
