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.

阿奎芬CRC三文鱼项目（Aquafin CRC Salmon Project）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）联合实施。流程研究1（Process Study 1）于2005年4月12日至14日在霍恩河口（Huon Estuary）隐湾（Hideaway Bay）外侧近海区域开展。本次空间调查从6个采样点位采集样品，分析指标涵盖营养盐、溶解氧、浮游植物物种鉴定、叶绿素与类胡萝卜素色素，以及水体中溶解态有色有机质（CDOM）、颗粒态（ap）与碎屑/非藻类（ad）组分的吸收系数。本次采样共设置三个深度：距水底0m、3m及3m，同时采集12m集成水柱样品；仅溶解氧的采样设置了两个深度：距水底0m与3m。本研究于2005年4月12日至13日连续两日完成全部6个采样点位的样品采集工作。在各站点正式采样前，使用Seaboard 4550型设备采集近水底的CTD（温盐深仪）剖面数据，并测定塞氏盘深度（Secchi depth）。

重要提示：浮游植物检测结果已于2012年6月完成修正更新。原L列与M列中的生物量单位存在错误，正确单位应为µL/L。已将原M、L列中的数值除以1000，且保留mL/L作为单位。其余指标（包括CPL及CPL组）的数值均未受影响。
