Data includes statistics concerning density, biomass, and diversity. Variations in these parameters are then related to concurrent hydrographic conditions and sea grass biomass. Christmas Bay was found to have greater overall density than reported in other sea grass habitats. However, all population parameters examined varied monthly and seasonally. Water temperature and salinity exerted the most significant effects, while sea grass biomass had only a small-scale, random effect. Background literature is reviewed, and all supportive data analyses are presented.sea grassmarine fishaquatic communitiesunderwater habitatssalinity effectstemperature effectsThesis
