Moss Control in Creeping Bentgrass Putting Greens

Moss (Bryum argenteum) continues to become one of the most problematic weeds in creeping bentgrass (Agrostis palustris) putting greens. Control of moss can be approached in many different ways, including chemical applications, and cultural practices such as correcting shading or poor drainage. A study was conducted at Springdale Country Club (Springdale, Ark.) to evaluate the effectiveness of s...

Greens Functions for 3-D Seismic Migration

The space-time Greens functions for 3-D poststack and 3-D prestack migration in a homogeneous medium are derived under the fareld approximation. These Greens functions can be used to practically compute synthetic migrated images. Examples are given for the recording footprint noise associated with a point scatterer and a meandering river channel. The Greens functions also provide fundamental in...
