Analysed data for the research paper "Turner et al: AUV-based classification of benthic communities of the Ningaloo shelf and mesophotic areas"
Ningaloo Outlook SRMP - AUV imagery data analysis - Published 06 Oct 2017
Herbivory is a key ecological process that sustains food webs, and can regulate the biomass of primary producers in an ecosystem. It has long been hypothesized that rates of herbivory are greatest in ... morethe tropics, although strong evidence to support this is limited. The aim of this project was to identify the key species of herbivores, to identify the grazing rates of key herbivores, and in conjunction with project WAMSI 2 KMRP Project 2.2.4 (benthic primary productivity) provide estimates of the proportion of production that is consumed by herbivores. The research on herbivory was focused on the islands and coast of the Bardi Jawi Indigenous Protected Area in the Kimberley (Western Australia), encompassing Jalan (Tallon Island) and Iwany (Sunday Island). Focus of the herbivory study was on one type of habitat (seagrass meadows), and the diet of two species of herbivores (golden-lined rabbitfish and green turtle). Four surveys were conducted between October 2014 and April 2016. At these locations the following measurements or collections were made (not all measurements were made during each survey): (1) Rates of herbivory (three surveys). These data are presented in the report for WAMSI KMRP 2.2.4, here the focus is on assessing rates of herbivory as a proportion of primary production; (2) Collections of golden-lined rabbitfish (Siganus lineatus); and (3) Blood samples from green turtles (Chelonia mydas). Ten green turtles were tagged with satellite tags: 4 in April 2015, and 6 in April 2016. This data record only pertains to data held by CSIRO.

This dataset contains the ichthyoplankton data from 3 National Reference Stations on the east coast of Australia (North Stradbroke Island, Port Hacking, and Maria Island), and comparable historical da... moreta from eight ichthyoplankton surveys that were used to provide a longer term context:
RV Sprightly (1983)
RV Challenger (1989-1991)
RV Franklin (1994)
RV Franklin (1997-1998)
RV Franklin (1998-1999)
RV Southern Surveyor (2004)
RV Investigator (2015)
FRV Kamala (1989-1993)
Refer to the published report which had the following goals:
- To evaluate the value of long-term monitoring of ichthyoplankton at selected locations in the Integrated Marine Observing System (IMOS) National Reference Station (NRS) network,
- To identify the potential of this monitoring for providing fishery-independent information relevant for marine fishes and their management.

Hydrographic data from six cruises, between April 1976 and March 1977 in the Gulf of Carpentaria are presented. Physical quantities (temperature, salinity and sigma-t) and chemical properties (dissolv... moreed oxygen, nitrate and silicate) were measured, and are presented in an associated report both as values at the stations and as contour maps - see the link in the related materials section to the report:
Rothlisberg P., White N.J. & Forbes A.M.G. (1989). Hydrographic Atlas of the Gulf of Carpentaria. CSIRO Marine Laboratories Report No. 209.
These cruises began in 1975 with the initiation of the CSIRO Tropical Prawn Research Project, a new series of Gulf-wide cruises undertaken to study the larval ecology of penaeid prawns.
Approximately 70 stations were occupied on each cruise (with the exception of KL 7/76 which made only three transects in the southern Gulf). Two types of hydrographic stations were undertaken. Type 'A' stations consisted of Nansen casts with bottles every 10m from the surface to the bottom, sampling temperature, salinity, oxygen, nitrate plus nitrite, nitrogen and silicate. Type 'B' stations were Nansen casts with three bottles (at the surface, at 10m depth and within 10m of the bottom) sampling the same parameters as the Type 'A' stations. The sigma-t values were calculated from the temperature and salinity values, and the percentage of oxygen saturation was calculated from the oxygen concentration, temperature and salinity data. The difference between surface and bottom values was also calculated for all properties.
The six cruises included:
KL 4/76 April 1976
KL 7/76 June 1976
KL 9/76 September 1976
