Abstract:

This study examined the effects of noise, temperature, humidity, motion, and light on the sleep patterns of the crew of HSV-2 SWIFT during Gulf of Mexico Exercise GOMEX 05-1. HSV-2 SWIFT was chosen for this study to examine crew sleep on an unconventional hull-type vessel manned with a small crew. Noise dosimeters, temperature and humidity monitors, actiwatches, and questionnaires were used to quantify the data. With the exception of light, the independent variables did not have a significant effect on participants sleep. This is likely due to the limited range of the independent variables and the small number of participants in the study 21 sailors. There were two major findings the relationship between the demographic variable sea time and participant sleep, and the relationship between the independent variable of light and participant sleep. Due to the limitations of the current study, it is recommended that further studies be conducted in more extreme operational environments. Additionally, studies such as the one discussed in this thesis should be completed on different platforms to determine the differences in environmental factors that affect sleep between hull types so that the results can be applied to future vessel design.
