Derwent Estuary Ambient Water Quality monitoring program - Site SC

Site SC is sampled monthly by the Derwent Estuary Program as part of the Derwent Ambient Water Quality monitoring program.\nSince 2003, ambient water quality monitoring has been carried out on a monthly basis at up to 28 sites throughout the Derwent estuary by Norske Skog Boyer, Nyrstar Hobart and the State Government. Monitoring is carried out by three different boat-based sampling parties, but is co-ordinated to occur on the same day each month. \nAt each site, in-situ field measurements are taken using calibrated sensors for temperature, salinity, pH, dissolved oxygen and turbidity. Water clarity is also measured using a secchi disk. Surface and bottom water samples are collected for analysis of true color, total suspended solids(TSS), total and dissolved nutrients, organic carbon and zinc. at most sites, depth integrated samples are also collected for chlorophyll a using a plastic tube. Bottom samples in the Middle and Outer estuary are collected using a niskin bottle. Pumps are used in the upper estuary site to fill up the bottles. All water samples are analysed at Analytical Service Tasmania, a National Association of Testing Authorities-accredited laboratory. Monitoring site depth is 2 meters

SC监测点由德文特河口项目（Derwent Estuary Program）按月采样，作为德文特河环境水质监测计划的一部分。
自2003年起，挪威纸业博耶厂（Norske Skog Boyer）、霍巴特尼斯特公司（Nyrstar Hobart）与塔斯马尼亚州政府，已在德文特河口沿线最多28个监测点开展月度环境水质监测工作。本次监测由三支不同的乘船采样团队负责，但所有采样均协调在每月同一天开展。
在每个监测点，研究人员使用经过校准的传感器开展原位现场测量，检测指标包括温度、盐度、pH值、溶解氧与浊度；同时采用塞氏盘（Secchi disk）测定水体透明度。
采集表层与底层水样，用于分析真色、总悬浮颗粒物（TSS）、总营养盐与溶解态营养盐、有机碳以及锌元素。在多数监测点，还会使用塑料管采集深度混合水样，用于叶绿素a的检测。
河口中段与外段的底层水样采用尼斯金采水器（Niskin bottle）采集；河口上段监测点则使用泵体完成采样瓶的注样工作。
所有水样均在塔斯马尼亚分析服务公司（Analytical Service Tasmania）进行检测，该实验室为澳大利亚国家检测机构协会（National Association of Testing Authorities）认可的检测机构。各监测点的水深为2米。
