Geophysicists measure, examine, and explore the physical properties of the Earth, from the deep interior to the near regions of space called the magnetosphere. Geophysics is a data driven field using large sensor arrays, remote sensing, and satellite observations to understand the Earth system. As a result, office work in geophysics often focuses on data processing using modern computing technology. Geophysics is an academic field that crosses over into the practical arena in a number of areas. For example, seismology is an academic discipline dedicated to understanding earthquake physics, but it also has an important applied function in the oil and gas industry. The fuel you use to drive your car is affordable because of technology developed by geophysicists over the past century. The fundamental physics of both, however, is the same. Specialization is significant early on when applying for jobs in geophysics because specialized course work for an academic versus industrial career path is somewhat different. A unique element of geophysics relative to other areas of applied physics is field work. Geophysical data often involves installation of sensor networks in remote areas making the field attractive to students with an interest in working in an outdoor laboratory setting.
Successful geophysicists are generally able to encompass the complexities of their profession. Many geophysicists come from a wide range of initial specialization. The most important academic background in geophysics is a sound foundation in fundamental mathematics and physics because most of the field builds on these foundations. Initial specialization is important, however, because it can reduce the time to completion of the degree program. Professionals tend to enjoy learning how complexities in the Earth system interrelate. Learning about new specialties often happens gradually and unconsciously during off hours.
