This dataset contains nutrient, temperature, salinity, chlorophyll a, suspended solids and light data from Jervis Bay, NSW. The data were obtained from 9 sites around Jervis Bay, every 3 months between 1989 and 1991. Data from monthly sampling for 2 years from 5 sites were also obtained. The data are part of the Jervis Bay Marine Ecological Study. NB - As the database has been lost, the only data still available are those published in the JERVIS BAY BASELINE STUDIES Final Report.

BOA is the result of collecting together the majority of global high-quality buoy and shipboard deepwater hydrographic cast data. It is built on the NOAA/NODC World Ocean Database (BOA06 uses WOD01), WOCE WHP3, Argo, TAO, CSIRO and NIWA archives, and a number of other sources. The component datasets of BOA are stored separately in a range of formats since the nature of these datasets is quite varied. This approach allows easy updating of components (for example, the Argo subset is completely renewed every couple of months.) Where the same data could reside in multiple datasets, those datasets are duplicate cross-checked after any updates (scanning only on the basis of time and location, not the enormous task of searching for duplicated property profiles.). BOA is available in a packaged form of one netCDF file per property (created in July 2006.) Neutral density profiles are also computed and stored in file gamma_BOA06.nc. These files are available via an OpenDAP server and for internal use as local netCDF files.

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. Prior to each microheterotroph grazing experiment, a CTD cast was performed at site P3 using the Seaboard 4550 to determine the depth of the fluorescence maximum. Water for a grazing experiment was collected from a depth of 20m (12 April) and 5m (13 April).

The Aquafin CRC Salmon Project is being undertaken by CSIRO Marine and Atmospheric Research (CMAR) and Tasmanian Aquaculture and Fisheries Institute (TAFI). Prior to the three microheterotroph grazing experiments, a CTD cast was performed at site PE3 to determine the depth of the fluorescence maximum. Water for the three grazing experiments was collected simultaneously from a depth of 7m. For all three experiments, the sample water was filtered through a 200µm mesh as usual. For the second experiment, 10 mesozooplankton were added to the sample water in each incubated bottle. In the third experiment 30 additional mesozooplankton were added to the sample water in each incubated bottle. The additional mesozooplankton were removed from the incubated bottles at the close of the experiment, before filtration. Samples were incubated for 24 hours with subsamples collected at times T0 and T24 for phytoplankton and microheterotroph counts, nutrient analysis and pigment concentration and composition. Grazing and growth rates were calculated.

The Aquafin CRC Salmon Project is being undertaken by CSIRO Marine and Atmospheric Research (CMAR) and Tasmanian Aquaculture and Fisheries Institute (TAFI). Monthly Monitoring 1 (MM1) was undertaken in the D'Entrecasteaux Channel by CMAR and in the Huon River by TAFI from 10 January 2002 until 31 March 2003. During MM1 samples were collected monthly from 12 sites in the D'Entrecasteaux Channel by CMAR for the analysis of nutrients, phytoplankton species identification, and chlorophyll a; samples were collected for salinity calibration and dissolved oxygen approximately four times a year from 3 sites. In December 2002, samples were collected for HPLC pigment analysis from 5 sites. Samples were collected monthly from 4 sites in the Huon River by TAFI for phytoplankton species identification, nutrients, spectrophotometric chlorophyll a and dissolved oxygen. This metadata record refers to the Monthly Monitoring 1 data collected by CMAR in the D'Entrecasteaux Channel. Two depths were sampled (0 and 1 m from the bottom) for the nutrient analyses, chlorophyll a analysis and dissolved oxygen. A 12 m integrated water column sample was collected for phytoplankton species identification and additionally for chlorophyll a analysis in the first 12 months of the monitoring. In December 2002, samples were collected from surface and bottom from 5 sites for HPLC pigment analysis. At each site prior to the collection of the samples a CTD profile to near bottom was collected using the SBE19-0605 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.

The Aquafin CRC Salmon Project is being undertaken by CSIRO Marine and Atmospheric Research (CMAR) and Tasmanian Aquaculture and Fisheries Institute (TAFI). Process Study 2 was undertaken between 21-22 September 2005 in the Huon Estuary offshore from Hideaway Bay. Prior to each microheterotroph grazing experiment, a CTD cast was performed at site P3 using the Seaboard 4550 to determine the depth of the fluorescence maximum. Water for a grazing experiment was collected from a depth of 2 m on the 21 September 2005 Samples were incubated for 24 hours with subsamples collected at times T0 and T24 for phytoplankton and microheterotroph counts, nutrient analysis and pigment concentration and composition.

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.
