Summary	This effort will explore the impact of alternative watchstanding schedules and manning levels on Sailors' work/rest patterns, alertness levels and training and qualification rates. Specifically, this effort will focus on the analysis of sleep, performance, training and manning data from 122 Sailors aboard the USS JASON DUNHAM previously collected in December 2012. According to the Naval Safety Center, sleep deprivation and fatigue are major causal factors in many Naval mishaps. In addition to sleep deprivation, fatigue can also result from undermanning. Manning at reduced levels increases Sailors' daily workloads because they must work longer hours to compensate for absent shipmates. The data collected will be used to support the improvement of current shipboard manpower models and manning strategies, creating a physiologically based model that will more accurately depict the onboard requirements based on various risk levels assumed by commanders.
