    This record contains data collected from the near-water surface sampling site off the Lucinda Jetty, as part of the Lucinda Jetty Coastal Observatory. Sample collection began the 9th of January, 2014. The data can be used for Ocean Colour sensor validation. Parameters measured include the absorption coefficients of the particulate and dissolved components of the water column and the phytoplankton pigment concentration and composition.

    Chlorophyll a is the most commonly used indicator of phytoplankton biomass and is a proxy for primary productivity in the marine environment. It is relatively simple and cost effective to measure when compared to phytoplankton abundance and is thus routinely included in many surveys. Here we collate 173,333 records of chlorophyll a collected since 1965 from Australian waters gathered from researchers, from regular coastal monitoring surveys to long ocean voyages. This dataset concentrates on samples analysed using spectrophotometry, fluorometry and high performance liquid chromatography (HPLC). The Australian Chlorophyll a database is freely available through the Australian Ocean Data Network portal (http://imos.aodn.org.au/). These data can be used in isolation as an index of phytoplankton biomass or in combination with other data to provide insight into water quality, ecosystem state, and / or the relationships with other trophic levels such as zooplankton or fish.

    This dataset comprises the results of phytoplankton pigment composition analysed from samples collected as part of the Integrated Marine Observing Systems (IMOS) National Mooring Network - National Reference Station (NRS) field sampling. Pigment samples are taken for the complete water column (0-50m) and at the depths of the shallow WQM and the deeper WQM attached to the mooring at that site. 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 freely available through the AODN portal: https://portal.aodn.org.au

    This record describes chlorophyll data collected as part of the 1991-1993 Tasmanian Slope Trophodynamics Study undertaken by CSIRO Division of Fisheries. Chlorophyll data were obtained from analyses of filters from Niskin bottle samples at a range of depths (surface to 1500 meters) on 4 cruises of FRV "Southern Surveyor" on three 60 km transects across the continental shelf to the south and south-east of Tasmania in July 1991 (cruise SS 02/91), February 1992 (cruise SS 01/92), November 1992 (cruise SS 04/92) and April 1993 (cruise SS 03/93). Analyses were carried out using spectrophotometric methods (cruise SS 01/92) and HPLC (3 remaining cruises), and analysed for chlorophylls a, b and c to give estimates of algal biomass in the water.

  • Phytoplankton pigment composition (chlorophyll a concentration) was measured in Albatross Bay, Gulf of Carpentaria, northern Australia. Four sites were sampled over six years between August 1986 and April 1992. In the last two years samples were taken at the bottom of the water column in addition to mid-depth.

    Benthic water quality measurements were obtained from nine sites across and outside Marmion Lagoon at varying depths (3m, 5m, 10m, 15m, 20m, 25m, 30m, 35m and 40m). Data was collected on Total Suspended Solids (TSS), Particulate Organic Matter (POM), Particulate Inorganic Matter(PIM), Chlorophyll-a, Phaeopigments, HPLC, Fatty acids, Nutrient Concentrations and Isotopes over December 2008 to March 2009.

    This record contains data collected at a total of 30 stations on an unknown vessel, off the coast of Darwin. The samples were collected from September 09-15 2013 as part of the National Environmental Research Program. The data can be used for Ocean Colour sensor validation. Parameters measured include Total Suspended Particulate Matter (TSM), including the organic and inorganic fractions; the absorption coefficients of the particulate and dissolved components of the water column and the phytoplankton pigment concentration and composition.

    This record contains data collected at a total of 45 stations on an unknown vessel, off the coast of Darwin. The samples were collected from March 28-April 4 2012 as part of the National Environmental Research Program. The data can be used for Ocean Colour sensor validation. Parameters measured include Total Suspended Particulate Matter (TSM), including the organic and inorganic fractions; the absorption coefficients of the particulate and dissolved components of the water column and the phytoplankton pigment concentration and composition.

  • This record contains data collected on the Lady Basten (AIMS cruise code LB2401/99) between 11 and 18 October 1999 from waters in the Great Barrier Reef near Rib Reef, Pandora Reef and Orpheus Island. The data can be used for Ocean Colour sensor validation. Parameters measured are the concentration of chlorophyll and carotenoid pigments and the absorption coefficient for dissolved (CDOM), particulate and detrital or non-algal components of the water column.

    This record contains data collected from a total of 20 stations on an unknown vessel, east of Deeral, Queensland. The samples were collected during January 2013. The data can be used for Ocean Colour sensor validation. Parameters measured include Total Suspended Particulate Matter (TSM), including the organic and inorganic fractions; the absorption coefficients of the particulate and dissolved components of the water column and the phytoplankton pigment concentration and composition.
