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

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 Pipeclay Lagoon. 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.

本数据集为塔斯马尼亚州太平洋牡蛎（Crassostrea gigas）养殖承载力研究的一部分，针对当地五个太平洋牡蛎养殖区——皮特沃特（Pittwater）、管黏土泻湖（Pipeclay Lagoon）、小天鹅港（Little Swanport）、乔治湾（Georges Bay）及辛普森湾（Simpsons Bay）——的理化参数开展了测定。本记录所呈现的数据采集自管黏土泻湖，为上述养殖区提供了极具价值的环境本底数据。除辛普森湾外，研究团队对其余四个区域的水动力特征进行了分析，涵盖高低潮水量、换水速率、流速及水深等值线等指标。各区域内的多个监测点位均按月开展监测，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。研究人员还在皮特沃特的两个监测点位，探究了上述参数在不同时间尺度下的变化规律，结果表明所测定的环境参数存在显著的时空异质性。
