1. A method for recovering a care from a downhole environment, comprising:
a) providing a measurements while drilling device and a coring apparatus within a wellbore, wherein the coring apparatus includes an inner tube configured to receive the core and a pressure sealed plug within the inner tube;
b) lowering the measurements while drilling device and the coring apparatus to an elevation where a core is to be obtained;
c) positioning the coring apparatus at the elevation where the core is to be obtained;
d) starting the coring apparatus;
e) conducting coring operations, including placing the pressure sealed plug in contact with the top of a core and allowing the pressure sealed plug to move freely through the inner tube as the pressure sealed plug is pushed by the core, thereby increasing pressure within the inner tube; and
f) using the measurements while drilling device to take at least one measurement within the inner tube of the coring apparatus during the coring operations, wherein the at least one measurement is a measurement selected from the group consisting of shock measurement, revolutions per minute measurement, vibration measurement and gamma radiation measurement.
