A local low-amplitude region underneath an attenuating zone, often associated with hydrocarbon accumulation or leakage of small amounts of gas into the section. May be a processing artifact such as caused by trace equalization, where a few large amplitude values included within the window tend to control the gain, or a result of velocity defocusing or irregularities in illumination.
