Aquafin CRC Salmon Project - Process Study 1- Water Column Spatial Survey - Huon Estuary - April 2005

The Aquafin CRC Salmon Project is being undertaken by CSIRO Marine and Atmospheric Research (CMAR) and Tasmanian Aquaculture and Fisheries Institute (TAFI). Process Study 1 was undertaken between 12-14 April 2005 in the Huon Estuary offshore from Hideaway Bay. During the spatial survey samples were collected from six sites for the analysis of nutrients, dissolved oxygen, phytoplankton species identification, chlorophyll and carotenoid pigments and the absorption coefficients for dissolved (CDOM) particulate (ap) and detrital or non-algal (ad) components of the water column. Three depths were sampled (0, 3 and 3 m from the bottom) as well as a 12 m integrated water column sample. The only exception was dissolved oxygen which was sampled only at two depths (0 and 3 m from the bottom). During this study samples were collected from each of the six sites on consecutive days (12 and 13 April). At each site prior to the collection of the samples a CTD profile to near bottom was collected using the Seaboard 4550 and the Secchi depth measured. PLEASE NOTE - The phytoplankton results were updated in June 2012 with a correction. The original biovolume unit in column L and M was incorrect and should have been µL/L. The values in column M and L have been divided by 1000 and the unit mL/L left unchanged. Other values are not affected including CPL and Group CPL.Aquafin CRC Salmon项目由澳大利亚联邦科学与工业研究组织海洋与大气研究所（CSIRO Marine and Atmospheric Research, CMAR）与塔斯马尼亚水产与渔业研究所（Tasmanian Aquaculture and Fisheries Institute, TAFI）联合开展。过程研究1于2005年4月12日至14日在胡恩河口Hideaway Bay近岸海域实施。本次空间调查共从6个站位采集样本，用于营养盐、溶解氧、浮游植物物种鉴定、叶绿素与类胡萝卜素色素分析，以及水体中溶解态（CDOM）、颗粒态（ap）和碎屑/非藻类（ad）组分的吸收系数测定。本次采样设置3个固定深度：表层（0m）、3m水深以及距海底3m处，另采集12m整层积分水柱样本。仅溶解氧项目仅在两个深度采样，即表层（0m）与距海底3m处。本次研究于4月12日、13日连续两日完成6个站位的样本采集。每个站位在采样前，均使用Seaboard 4550型设备采集近底温盐深（CTD）剖面，并测量塞氏盘透明度深度。请注意：浮游植物分析结果已于2012年6月完成修正更新。原数据L列与M列的生物量单位存在错误，正确单位应为微升每升（µL/L）；原M、L列数值已除以1000，且保留毫升每升（mL/L）作为单位。其余参数（包括CPL及CPL组）的数值均未受影响。
