1. A system for transferring at least one subterranean core sample under pressure, the system comprising:
a retrieval vessel that collects and houses the at least one subterranean core sample at a sampling pressure at which the at least one subterranean core sample is collected;
a valve having an open position and a closed position;
a linear actuator that couples to the retrieval vessel through the valve when the valve is in the open position at a first time, wherein the linear actuator facilitates removal of at least one pressure barrier from the retrieval vessel through the valve at the first time while maintaining the sampling pressure of the at least one subterranean sample;
a testing vessel that couples to the linear actuator through the valve when the valve is in the open position at a second time; and
a hydraulic device that facilitates pressurizing the testing vessel to the sampling pressure at the second time,
wherein the testing vessel and the retrieval vessel are coupled to each other through the valve at a third time, wherein the at least one subterranean core sample is transferred from the retrieval vessel through the valve to the testing vessel at the third time at the sampling pressure when the valve is in the open position,
wherein the linear actuator installs a pressure barrier in the testing vessel, and
wherein the at least one subterranean core sample, once transferred to the testing vessel, is tested at a fourth time while in the testing vessel at the sampling pressure.
