Aquafin CRC Salmon Project - Monthly Monitoring 2 - D'Entrecasteaux Channel and Huon Estuary - Sept 2004 - Oct 2005

The Aquafin CRC Salmon Project is being undertaken by CSIRO Marine and Atmospheric Research (CMAR) and Tasmanian Aquaculture and Fisheries Institute (TAFI). Monthly monitoring 2 (MM2) was undertaken in the Huon River and D Entrecasteaux Channel from 20 September 2004 until 19 October 2005, except that there was no sampling in May or July 2005. During MM2 samples were collected monthly from 11 sites for the analysis of nutrients, phytoplankton species identification, chlorophyll and carotenoid pigments and turbidity; samples were collected approximately every second month from 3-4 sites for dissolved oxygen (TAFI). Two depths were sampled (0 and 1 m from the bottom) for the nutrient analyses, dissolved oxygen and spectrophotometric chlorophyll (TAFI) and two depths were sampled for turbidity (1m and 5m). A 12 m integrated water column sample was collected for the CMAR HPLC pigment analysis and phytoplankton species identification. At each site prior to the collection of the samples a CTD profile to near bottom was collected using the SBE19-4550 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三文鱼项目由CSIRO海洋与大气研究中心（CMAR）及塔斯马尼亚水产养殖与渔业研究所（TAFI）联合开展。月度监测2期（MM2）于2004年9月20日至2005年10月19日期间在霍恩河（Huon River）与德安特卡斯特奥海峡（D'Entrecasteaux Channel）实施，仅2005年5月和7月未进行采样。

MM2期间，每月从11个站点采集样本，用于营养盐分析、浮游植物种类鉴定、叶绿素与类胡萝卜素色素检测及浊度测量；每两个月左右从3-4个站点采集样本，供TAFI开展溶解氧分析。营养盐、溶解氧及分光光度法叶绿素分析（TAFI负责）的样本取自两个深度（距底0米与1米）；浊度样本取自两个深度（1米与5米）。为支持CMAR的高效液相色谱（HPLC）色素分析与浮游植物种类鉴定，采集了12米水柱综合样本。每个站点采样前，使用SBE19-4550仪器获取近底温盐深剖面（CTD profile）数据，并测量塞奇深度（Secchi depth）。

请注意——浮游植物分析结果已于2012年6月更新并修正：原L列与M列的生物体积单位有误，应调整为µL/L；M列与L列数值已除以1000，而单位mL/L保持不变；CPL及Group CPL等其他数值不受影响。
