Are ENU coordinates corrected for magnetic declination?

Posted by Amanda Kahn at July 16. 2017

We deployed two Aquadopp Profilers earlier this year; both were set to record using ENU coordinates.  I performed compass calibrations of both beforehand, at the same latitude as our study site because I couldn't tell if the calibration procedure is used to account for magnetic declination.  At our site, that declination is about 18 degrees so can have a big effect on our ENU readings.  Does any internal processing account for that? Or should we correct for that now, in post-processing?
