Subject: undershooting, shooting
Добрый день,

перевожу документ о морской сейсморазведке. Подскажите, пожалуйста, как правильно сформулировать перевод данных слов:

Once  again  the  technique  of  shooting  lines  in  two  directions  and splitting the swaths in half, was employed to maintain as efficient a production method as was possible.

shooting  line - взрывной профиль

Undershoot line changes using the nominal of 2 hours.

undershoot line - профиль подстрела???

Line type - P for prime, R for re-shoot, U for undershoot and I for infill.Тип профиля - P для первичного подстрела, R для повторного подстрела, U для подстрела??? и I для уплотнения.

Undershooting = Seismic surveying using a source on one side of an obstacle or property into a spread on the opposite side in order to obtain subsurface coverage under the obstacle or property itself. Used when the surface of the property is inaccessible (such as on a line crossing a river) or to get data beneath some feature whose presence might introduce intolerable uncertainties if measured through it (such as to map beneath a salt dome).
