Physical and chemical parameters of several oyster growing areas in Tasmania: Simpsons Bay

Physical and chemical parameters at five Pacific oyster (Crassostrea gigas) growing areas in Tasmania - Pittwater, Pipeclay Lagoon, Little Swanport, Georges Bay and Simpsons Bay - were measured as part of a study to determine the carrying capacity of the areas for oyster farming. The data represented by this record, was collected in Simpsons Bay. This has provided valuable environmental data for these areas. The hydrodynamic regimes at each area except Simpsons Bay were studied, including high and low water volumes, flushing rates, flow rates and depth contours.

Temperature, salinity and concentrations of nitrates, phosphates, silicates and chlorophyll a were measured monthly at several sites in each area. The change in these parameters over different time scales also was examined at two sites in Pittwater and indicated temporal and spatial variability in the environmental parameters measured.

本数据集源自一项旨在评估塔斯马尼亚地区5处太平洋牡蛎（Pacific oyster，*Crassostrea gigas*）养殖区——皮特沃特（Pittwater）、管粘土泻湖（Pipeclay Lagoon）、小天鹅港（Little Swanport）、乔治湾（Georges Bay）及辛普森湾（Simpsons Bay）——的牡蛎养殖承载力的研究，研究期间对各养殖区的理化参数进行了测定。本记录所代表的数据采集自辛普森湾，为上述区域提供了极具价值的环境监测资料。
除辛普森湾外，研究团队对其余4处养殖区的水动力状况展开了调研，涵盖高低潮水量、水体交换率、流速及水深等值线等指标。各区域的多个监测站点均按月测定水温、盐度，以及硝酸盐、磷酸盐、硅酸盐与叶绿素a的浓度。研究还在皮特沃特的2处监测站点考察了上述参数在不同时间尺度下的变化特征，结果显示所测定的环境参数存在显著的时空变异性。
