1. A system, comprising: (a) a data retention device; (b) a plurality of distributed sensor nodes, each respective sensor node operable to sense a parameter; (c) a computing device operable to communicate with the plurality of distributed sensor nodes and to communicate with the data retention device; and (d) one or more instructions which, when executed by the computing device, cause the computing device to: (i) store a parameter sensed by one or more of the plurality of distributed sensor nodes in a first sensor data set in the data retention device; (ii) receive an input selection corresponding to a target-occurrence; (iii) search the first sensor data set for data correlating to the target-occurrence; and (iv) store data correlating to the target-occurrence in the data retention device.
