This dataset comprises the measurement of Secchi Depth and Total suspended solids (inorganic and organic components) analysed from samples collected as part of the Integrated Marine Observing Systems (IMOS) National Mooring Network -National Reference Station (NRS) field sampling. Nine Sites are included in the IMOS NRS field sampling stations. Maria Island (TAS), Kangaroo Island (SA), Esperance (WA), Rottnest Island (WA), Ningaloo (WA), Darwin (NT), Yongala (QLD), North Stradbroke Island (QLD) and Port Hacking 100 (NSW). Sampling at these sites is conducted by several members of IMOS NRS Biogeochemical project. Sampling at the sites began between 29/9/2008 and 8/11/2010 and is currently ongoing for 7 sites. Sampling ceased at Ningaloo and Esperance (WA) sites in Aug/Sept 2013. Sampling is conducted monthly (Esperance and Ningaloo were 3 monthly) off small vessels. Depths sampled range from surface to 105 metres depending on the site. Depths are usually sampled at 10 metre intervals. Details including information on station locations, depths sampled and sample types collected are shown in the PDF link below extracted from the IMOS NRS NATIONAL REFERENCE STATIONS BIOGEOCHEMICAL OPERATIONS - A PRACTICAL HANDBOOK, Version 2.2 July 2012. A link to the full handbook is also provided which includes full details of the sampling regime and analyses. Historical data collected as part of CSIRO Coastal Monitoring program is available for three of the National Reference Station sites: Maria Island Coastal Station Data 1944-2008, Port Hacking 100m Coastal Station Data 1953-2010 and Rottnest Island Coastal Station Data 1951-2009. The links to the metadata and access for these data is provided below. Data storage and access is planned to be interoperable with other national and international programs through the IMOS Infrastructure. Station metadata can be found through this resource. Data is available freely via the AODN portal: https://portal.aodn.org.au.
This dataset contains the results from algal bloom surveys in the Swan River, Perth, Western Australia. Aeroplane flights were used to map the extent of the blooms and at the same time, sea truthing of the images were made using an analysis for various pigments and obtaining phytoplankton samples. Four flight periods were made between October 1994 and December 1995, with up to 4 flights a day. The main species studied was the dinoflagellate Gymnodinium.
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). 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.

Terrestrial landscapes and coastal marine environments are linked by the rivers that flow between them. This is particularly true in the Kimberley, where each year large amounts of freshwater enter coastal waters. This project aimed to understand how dissolved and particulate material from freshwater systems in the Kimberley are transported by the tides and currents into the coastal marine environment and whether these exports from land play a role in coastal productivity. The project linked closely with WAMSI 2 KMRP projects 2.2.1 and 2.2.2 to better understand how freshwater discharge influences marine food web structure and sustains the productivity of Kimberley inshore ecosystems. Oceanographic and biogeochemical data was collected over two field campaigns (October/November 2013 and April/May 2014) from the Walcott Inlet, Collier Bay area (16° 22.624’S 124° 26.235’E to 16° 24.487’S 124° 54.035’E) and models integrated with those for Collier Bay (KMRP Project 2.2.2). The hydrology component focussed on catchments flowing into Walcott Inlet and Collier Bay, but climate projections and stream flow data analysed for whole of Kimberley. Chemical data to apportion sources of organic matter was also collected. This data was used to support development of the biogeochemical model. No primary data was collected in the hydrology component, but major data sets were collated, including data from 88 streamflow gauging stations managed by the Department of Water. A coupled physical-biogeochemical model and a catchment carbon export model was developed to understand the link between exported material and coastal productivity and has been an important component of the research project as it has allowed estimates of freshwater flow under current and future climate scenarios and an estimate of export of nutrients (carbon and nitrogen) and the forms in which they exist. Historical data used from 1961 to 2012 was used for calibration of the model, and future simulations were run for the period 2013 – 2064. This metadata record only relates to data either collected or generated by CSIRO. For data held by other project partners, please refer to the ‘supplementary information’ section.
This dataset describes data collected from 5/11/96 to 5/10/98 in the Huon Estuary, Tasmania at weekly or fortnightly time frames depending on algal bloom conditions. Data were collected at five of the biological station from the Huon Estuary Spatial Surveys (see separate MarLIN entry). The five stations were located at Hideaway, Kilalla, and Wheatley's Bays, Brabazon Park and Port Cygnet. At each sampling station a CTD was deployed and three niskin bottle samples were taken, one at each of the surface, middle and bottom water layers. Bottle samples have been analysed for salinity, dissolved oxygen, nutrient and pigments. An integrated water sample (for algal presence data) and a phytoplankton net sample were also taken. During algal blooms spectral absorption was analysed and algal counts were calculated.
This dataset describes data collected from the Huon Estuary (Tasmania). Data was collected over a four day period during August/September 1998. Data was collected from 14 sites, ranging from 0 salinity at Judbury to a salinity of 35 at the seaward end of the estuary near Huon Island. Sites were selected to as possible sources of contaminants. Most sites were a subset from the Huon Estuary Study spatial surveys (refer to separate metadata record). Water samples were collected during the first three days. These samples were collected for salinity, dissolved oxygen, nutrients, trace metals, pesticides, pigments, spectral absorbance and phytoplankton. Sediment samples were collected during the last day. These samples were collected for organic tracers, pesticides, mercury and phytoplankton cysts. (Refer to the SED1 metadata record for more sediment information from the Huon Project.) This dataset forms part of the CSIRO Marine Research Huon Estuary study, conducted over the period 1996-1998.
This dataset describes data collected from the Huon Estuary (Tasmania). Data was collected over a three day period approximately every three months from March 1996 until August 1998. 10 surveys were completed (HES1 to HES10). Data was collected from 61 sites, ranging from 0 salinity at Judbury to a salinity of 35 at the seaward end of the estuary near Huon Island. 5 sites were located near fish farms (refer to the separate metadata record for weekly data at these sites). At these sites, data was collected for all parameters (CTD, salinity, dissolved oxygen, nutrients, pigments, spectral absorbance and phytoplankton) measured. At a further 31 sites spread over the estuary, data was collected for the physical and chemical parameters only. At the remaining 25 sites, only physical (CTD) data was collected. Below Port Huon, samples were collected at three depths - surface, fluorescence maximum and from within the salt wedge. Above Port Huon, samples were collected from the surface and from the salt wedge (where present). This dataset forms part of the CSIRO Marine Research Huon Estuary study, conducted over the period 1996-1998.
Process Study 4 was undertaken in Port Esperance on 01 November 2007. During the spatial survey samples were collected from eight sites for the analysis of nutrients, phytoplankton species identification, chlorophyll and carotenoid pigments and the absorption coefficient for the dissolved (CDOM) component of the water column. Three depths were sampled (0, 3 and 2 m from the bottom) for the nutrient analyses, a surface sample was collected for the CDOM analysis and a 12 m integrated water column sample was collected for the pigment analysis and phytoplankton species identification. At each site prior to the collection of the samples a CTD profile to near bottom was collected and the Secchi depth measured. A further sample was collected, using a bucket, from near the bridge at Port Esperance and analysed for salinity, CDOM absorption and nutrient concentration. 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 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.
