This dataset contains data collected by the Australian Continuous Plankton Recorder (AusCPR) survey and is funded by IMOS (Ships of Opportunity sub-facility) and CSIRO. The aims of the AusCPR survey are to: * map plankton biodiversity and distribution * develop the first long-term plankton baseline for Australian waters * document plankton changes in response to climate change * provide indices for fisheries management * detect harmful algal blooms * validate satellite remote sensing * initialise and test ecosystem models. The survey conducts repeat tows in the GBR, the East Australian Current and down to the Southern Ocean Time Series Mooring (SOTS). Other routes are conducted on an adhoc nature around Australia. The dataset also contains phytoplankton data from the UTAS / AAD led Southern Ocean CPR (SOCPR) project which is also funded by IMOS. The datasets available in this collection include Phytoplankton Colour Index (an estimate of chlorophyll in the water), phytoplankton abundance, zooplankton abundance and a biomass index from AusCPR and phytoplankton abundance from SOCPR. This data are freely available through the AODN portal: https://portal.aodn.org.au. This data is freely available but please acknowledge all relevant parties, as detailed in acknowledgement section.

This dataset contains geoscientific data logged during TELVE cruise (SS02/03) on RV Southern Surveyor 14.3-3.4.2003 in Tonga and Eastern Lau Basin. These data include logged station coordinates and information for dredges, CTD/hydrocasts, echosounder and camera/video operations and geological samples. The TELVE expedition completed 70 dredges, 31 tow-yos, 14 vertical hydrocasts, 9 echo-sounding traces, 2 camera tows, and 1 drogue test. The major scientific objectives of the cruise were a study of the hydrothermal plume activity of the Tofua Arc and adjacent Valu Fa back arc Ridge coupled with sampling of the sea floor with grabs and dredges. Sampling was conducted along the axis of the Valu Fa Ridge, the Tofua Arc between about 21o 30” and 24o 10’S, and one transverse hydrothermal cast from the backarc to arc region at ~ 22o 30’S was done. More specifically, objectives of the voyage were: 1.Perform a continuous along-axis survey for hydrothermal activity along the three segments of the Valu Fa back arc spreading ridge. 2. To the extent possible, conduct a systematic survey for hydrothermal activity along the S. Tonga arc adjacent to the Valu Fa Ridge. 3. Compare (for the first time) the incidence and chemistry of hydrothermal emissions along the adjacent back arc ridge and volcanic arc sections. 4. Coordinate results of back arc ridge survey with RIDGE 2000 investigators slated to perform similar surveys further north on Lau back arc spreading ridges.

Tests were carried out to investigate target response using 3 frequencies of echosounder data, giving an output in the form of digital traces. The data were collected during the FRV Southern Surveyor cruise SS 02/97 which travelled from Cairns to Karumba to Gove to Darwin.

A) Rates of primary productivity for reef macroalgal and sediment microalgal communities will be determined from measurements of oxygen release (and/or CO2 consumption) collected from reef (3x) and bare sand/microphytobenthos (3x) communities using benthic chamber incubations. B) Nutrient enrichment experiments - response of macroalgae will be measured in terms of N assimilation in algal tissue, changes to species composition and changes in abundances. The response of consumers (abundance and other aspects of population dynamics, biomass, feeding biology and fecundity) will also be investigated, using video for mobile (fish) grazers, and quadrat sampling for less mobile grazers (eg. gastropods on reefs, urchins in sediments). Variations in the isotopic composition of the algae and consumers will be used to assess nutrient exposure and subsequent energy flow pathways into secondary production.

The dataset is a compilation of records of sea turtles caught in prawn trawls in the Northern Prawn Fishery (NPF). There are 316 records of five species. The records are from research voyages, scientific observers on commercial prawn trawlers and crew member observers on commercial prawn trawlers. More specifically, the data sources were as follows: (a) CSIRO and collaborative research voyages on RV Southern Surveyor; (b) crew member observers on NPF commercial vessels, 2003-2005 (FRDC project 2002/035, collaboration between CSIRO and AFMA, funding by FRDC); (c) scientific observers on NPF commercial vessels (FRDC project 2000/173, collaboration between CSIRO and the Australian Maritime College (AMC), funding by FRDC); (d) crew members and scientific observers on NPF commercial vessels (FRDC project 1998/202, collaboration between BRS, CSIRO, AFMA, funding by FRDC and NORMAC); (e) crew member observers and scientific observers on NPF commercial vessels and RV Southern Surveyor (FRDC project 1996/257, collaboration between CSIRO, DPIQ and AMC, funding by FRDC).

This data set contains Simrad EK500 single beam echosounder data at 38 and 120 kHz and Simrad EA500 single beam echosounder data at 12 kHz from the Southern Surveyor. The EK500 data is primarily for water column characterisation (fish stocks, microplankton distribution) and on occasions for seabed classification (particularly prior to the EM300 swath mapper being installed), while the EA500 data is primarily for bathymetric readings.

Incidental photographs of field activities were taken by field staff during research voyage SS 03/2005 on the RV Southern Surveyor. Subjects include the research vessel, prawn trawls, epibenthic sleds, CTD casts, box cores and life on the ship.

This biological overview for the Southern Surveyor voyage SS 07/2005. The voyage took place off the Western Australian Coast during July August 2005. This dataset has been partly processed and has not yet been archived within the CSIRO Marine and Atmospheric Research Data Centre in Hobart. Additional information regarding this dataset is contained in the cruise report for this voyage and/or the data processing report. On this cruise pigments and chlorophyll a were collected by Neale Johnston and later processed at CMAR, Hobart by Pru Bonham.

This biological overview for the Southern Surveyor voyage SS 02/1999. The voyage took place in waters off Cape Grim and in the Southern Ocean during February 1999. This dataset has been partly processed and has not yet been archived within the CSIRO Marine and Atmospheric Research Data Centre in Hobart. Additional information regarding this dataset is contained in the cruise report for this voyage and/or the data processing report. On this cruise pigments and chlorophyll a were collected by (Unknown) and later processed at CMAR, Hobart by Pru Bonham. This cruise complements work done in the same region on Southern Surveyor in spring 1995 (SS 11/95), and on Aurora Australis in late summer, 1998.
