1. A system for conductivity concentration profiling, the system comprising:
a deployment mechanism configured to be lowered to a seafloor, wherein the lowered deployment mechanism contacts the seafloor; and
a conductivity concentration profiler (CCP) system coupled to the deployment mechanism, wherein the CCP system is configured to be detachable from the deployment mechanism, wherein the CCP system, once detached from the deployment mechanism, is not coupled to any other object, and wherein the CCP system comprises a probe located at a distal end of the CCP system, the probe being configured to measure sediment concentration in water around the deployment mechanism, wherein the CCP system comprises an adjustment mechanism allowing for vertical adjustment of the CCP system relative to the lowered deployment mechanism allowing a tip of the probe to maintain contact with the seafloor when deployed,
wherein the CCP system further comprises:
an enclosure coupled to the probe, wherein the enclosure comprises:
a probe side endcap coupled to the probe;
a printed circuit board (PCB) coupled to the probe side endcap, wherein the PCB comprises a controller configured to receive data regarding the sediment concentration from the probe and transmit the data for storage; and
a battery coupled to the PCB;
wherein the controller, independent of a cable connection external to the CCP system, controls the CCP system in a burst sampling mode to activate and to de-activate an active logging of measured data when the CCP system is deployed to minimize battery drain.
