SeaQuest2

Get To The Point Faster.

Diagram depicting SeaQuest2's ability to go from Data Collection to creation of Analytic Signal Maps without the need to apply corrections or create a total field map

Gradient Data

SeaQuest measures the gradients in all three directions simultaneously, and computes the total gradient, which is invariant of heading and orienta- tion. No matter how your heading changes, no information is lost.

Horizontal gradiometers, on the other hand, can only measure the gradient in one axis (direction).

This means that whenever the heading or tilt of a 1-axis gradiometer changes, so does the direction of the measured gradient, making it more chal- lenging to capture consistent line data.

Analytic Signal Mapping

Analytic Signal data suppresses geology and en- hances small nearby targets, enabling you to see more of what you want to see, while suppressing what you don’t want to see. Single-axis gradiom- eters and arrays can only do this in one of three possible directions. Since SeaQuest measures the complete 3-dimensional gradient, it enhances signals from small targets uniformly, regardless of their geometry or position in space. BAM software (included with SeaQuest) allows you to visualise SQ data.
