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.
