Physical and chemical parameters of several oyster growing areas in Tasmania: Georges 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 Georges 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.

为评估塔斯马尼亚州皮特沃特（Pittwater）、泥礁湖（Pipeclay Lagoon）、小天鹅港（Little Swanport）、乔治湾（Georges Bay）与辛普森湾（Simpsons Bay）这5个太平洋牡蛎（Pacific oyster，Crassostrea gigas）养殖区的牡蛎养殖承载力，研究人员对各区域的物理化学参数开展了测定。本数据集收录的数据采集自乔治湾，为上述养殖区域提供了宝贵的环境数据。除辛普森湾外，研究团队还对其余各区域的水动力状况展开了调研，涵盖高低潮水量、换水率、流速与水深等值线等指标。
各养殖区域的多个监测点位均按月监测水温、盐度以及硝酸盐、磷酸盐、硅酸盐与叶绿素a的浓度。此外，研究人员在皮特沃特的两个监测点位分析了上述参数在不同时间尺度下的变化特征，结果表明所监测的环境参数存在显著的时空变异性。
