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

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 from Pittwater. 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.

本数据集隶属于塔斯马尼亚太平洋牡蛎（Crassostrea gigas）养殖承载力研究，针对当地五处牡蛎养殖区——皮特沃特（Pittwater）、管黏土潟湖（Pipeclay Lagoon）、小天鹅港（Little Swanport）、乔治湾（Georges Bay）与辛普森湾（Simpsons Bay）的理化参数开展了测定。本记录对应的数据采集自皮特沃特，为上述养殖区提供了极具价值的环境监测资料。除辛普森湾外，研究团队对其余四区的水动力特征进行了分析，涵盖高低潮水量、水交换率、流速及等深线等指标。各区域的多个采样点均实施月度监测，测定参数包括温度、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采样点探究了上述参数在不同时间尺度下的变化特征，结果显示所监测的环境参数存在显著的时空变异性。
