Abstract: A method for transmitting signals in a subsea environment includes determining that a quality of an acoustic signal is below a threshold. The acoustic signal travels from a first device, through water in the subsea environment, to a second device. A parameter of the first device, the second device, or both is then adjusted to improve the quality of the acoustic signal when the quality of the acoustic signal is below the threshold.

Abstract: Methods and apparatuses for geophysical surveying are disclosed. In one embodiment, an airborne vehicle may obtain magnetic measurements in a location around a drilling site. The magnetic measurements may be used to calculate a localized disturbance magnetic field resulting from, for example, solar flares. The localized disturbance magnetic field may be used to calculate a declination value and, thus, a wellbore position with improved accuracy.

Abstract: Methods and apparatuses for geophysical surveying are disclosed. In one embodiment, a vehicle may obtain magnetic measurements in a location around a drilling site while a marine vehicle maintains an approximately stationary position nearby. The magnetic measurements from the two vehicles may be used to calculate a localized magnetic crustal field. The localized magnetic crustal field may be used to calculate a geomagnetic reference field that may be used to calculate and/or adjust wellbore position with improved accuracy.
