Members of dual-career couples in geophysics face challenges, including hidden biases and work-life balance issues. Couples should discuss potential opportunities and scenarios on a regular basis to be better prepared if one partner gets an opportunity for a promotion, a relocation, a heavier travel schedule, longer working hours, or even a layoff. Couples need to recognize that frequently, many compromises are necessary to coordinate two careers. Faced with similar trade-offs, people make different choices and manage to sustain relationships despite geographic separations and/or major career compromises. Travel and fieldwork are an important part of working in the geophysics world. These trips present a huge strain on their relationship, but couples have made it work with the help of technology like FaceTime and Skype to keep in touch. Dual-career couples should be aware of what best-in-class employers are doing to accommodate 'family life-cycle stages' and leverage this knowledge in negotiations with their employers throughout their careers.

Seismic data with reliable amplitude and phase can significantly impact drilling programs by providing valuable descriptions of the reservoir and overburden, especially for complicated or subtle plays. Processing steps such as velocity tomography and amplitude-preserving migration are critical for producing high-quality seismic images, but equally important are surface-related premigration processing steps that can significantly alter seismic amplitude and phase information, such as deconvolution. During land dynamite seismic acquisition, source and receiver responses are affected by surface conditions and inhomogeneous weathering layers. For example, even with the exact charge size, the response from each shot can vary greatly as the medium around the charge changes. Receiver recordings are affected similarly by nearsurface conditions. An improper correction or a lack of correction for near-surface anomalies during seismic preprocessing will reduce the subsurface resolution and negatively bias subsurface descriptions that are dependent on reliable amplitude and phase information. Surface-consistent deconvolution can help to attenuate surface-consistent biases. There are several ways to quality-control (QC) this processing step. Different consequences result from various choices of deconvolution parameters.
