RAN CTD Profile Data - HMAS LEEUWIN ProjectID: HI556LEE_M From: 2014-10-18 To: 2014-12-07

This dataset contains quality controlled vertical profiles of pressure, temperature and salinity measured by a Conductivity, Temperature and Depth (CTD) probe. The dataset contains 190 CTD profiles (casts) obtained during RAN Hydrographic Survey cruise HI556LEE_M from HMAS LEEUWIN.
The CTD was manufactured by Applied Microsystems Limited and is the "Micro CTD" model. This CTD type is referred to operationally as the MVP200_CTD. This CTD is fitted with a 4 electrode platinized conductivity cell, thermistor temperature sensor and a semiconductor strain gauge pressure sensor.
The CTD sensors are calibrated at the manufacturer Applied Microsystems Limited on a 12-18 month schedule. The CTD temperature sensor is calibrated against 'Hart' temperature standards. The pressure sensor is calibrated using 'Budenburg Deadweight' standards. The conductivity sensor is calibrated using 'Hart' temperature standards and seawater samples of known conductivity.
The CTD sensors are mounted to a fish-shape probe. The probe is controlled by an electric winch (MVP200 type). For downcasts the fish is allowed to free-fall (winch is in 'free-wheel' mode) under its own weight at about 2-3 ms-1 and then is winched back. Data is recorded in downcast and usually in upcast direction at a sampling rate of 25 Hz. The downcast data is of higher quality because sensors encounter undisturbed seawater that flows through the nose of the fish. On the upcast the fish is flipped around (tail first) and the sensors in the nose encounter disturbed flow from the fish tail.
This type of CTD is prone to a phenomenon called 'salinity spiking' caused by a mismatch between the response times of the temperature and conductivity sensor. Data undergoes a salinity de-spiking routine to correct for this. See the history metadata for further details on the salinity de-spiking process.
Raw CTD pressure data is not always monotonic due to transient up/down motion of winch/ship. Raw pressure data is subsetted to give a monotonic (increasing) sequence and then linearly interpolated to 1 decibar pressure intervals. Data is then flagged with quality control flags after visual inspection and comparison to average climatology and historical CTD casts.

Derwent Estuary Ambient Water Quality monitoring program - Site LB

Site LB is sampled monthly by the Derwent Estuary Program as part of the  Derwent Ambient Water Quality monitoring program.
Since 2003, ambient water quality monitoring has been carried out on a monthly basis at up to 28 sites throughout the Derwent estuary by Norske Skog Boyer, Nyrstar Hobart and the State Government. Monitoring is carried out by three different boat-based sampling parties, but is co-ordinated to occur on the same day each month. 
At each site, in-situ field measurements are taken using calibrated sensors for temperature, salinity, pH, dissolved oxygen and turbidity. Water clarity is also measured using a secchi disk. Surface and bottom water samples are collected for analysis of true color, total suspended solids(TSS), total  and dissolved nutrients, organic carbon and zinc. at most sites, depth integrated samples are also collected for chlorophyll a using a plastic tube. Bottom samples in the Middle and Outer estuary are collected using a niskin bottle. Pumps are used in the upper estuary site to fill up the bottles. All water samples are analysed at Analytical Service Tasmania, a National Association of Testing Authorities-accredited laboratory. Monitoring site depth is 2 meters

Geomorphology, habitats and surficial sediments of the Ningaloo Reef continental shelf and reef system: implications for biodiversity

The establishment and extension of Sanctuary Zones (SZ) in the Ningaloo Marine Park (NMP) has necessitated improvements in the understanding of the biodiversity and distribution of benthic habitats in the reef lagoon, its seaward barrier and the adjacent shelf environment.  My PhD research, supportedby the Ningaloo Research Program (NRP), aims to characterise the geomorphology and surficial sediments in bith the reef system and continental shelf, and identify and evaluate their influence on the spatial distribution of benthic habitats and communities.  A major collaborative project, co-funded through NRP and supported by expertise from the Australian Institute of Marine Science (AIMS), Curtin University of Technology, the University of WA, the WA Museum and Sydney University, aims to characterise the biodiversity and key ecological processes of the deepwater habitats, offshore of the fringin reef to 110m.   Over 100 kilometers of the northern secto of the Marine Park has been examined using a variety of sampling techniques including underwater video, acoustic mapping and traditional sampling techniques.  Towed underwater video cameras and onboard  live classifications were used to chartacterise habitats and their community structures.  Australia's most advanced Autonomous Underwater Vehicle (AUV), which takes high resolution 3D stereo images of the seafloor, was trialed for the first time.  Surficial sediment grabs were taken at or close to video stations to describe the various sediment facies and characterise the physical and biological properties.  Species samples, including spectacular sponge gardens, were collected using benthic sleds in representative habitats to form the basis of a deepwater seabed biodiversity database.  Baited Remote Underwater Vehicle System (BRUVS), deployed in target habitats, will help determine the significance of spatial habtat variables in structuring demersal fish demograophics and assemblages.  Detailed seabed mapping was undertaken in selected areas usinf multibeam and sinlebeam acoustics to generate information on bith the seabed bathymetry and texture, aiding in the preparation of marine habitat maps of the areas surveyed, and provide surrogate information for additional broadscale biodiversity assessments. In addition, work is currently underway to investigate four areas in the backreef area adjacent to those surveyed offshore.  Similar methods and sampling applied to shallow water have been used, including aerial photography and hyperspectral satellite interpretation, sediment grabs and probes, scuba video-transects within the deep water within habitats for both benthos and fish characterisation, and BRUVS.  This research, in addition to the deep water, will help to build a picture of how each process contributes to the whole system and the sustained health of the reef environment.

RAN CTD Profile Data - HMAS MELVILLE ProjectID: HI384MEL_H From: 2004-01-25 To: 2004-03-24

This dataset contains quality controlled vertical profiles of pressure, temperature and salinity measured by a Conductivity, Temperature and Depth (CTD) probe. The dataset contains 32 CTD profiles (casts) obtained during RAN Hydrographic Survey cruise HI384MEL_H from HMAS MELVILLE. 
The CTD was manufactured by Falmouth Scientific and is the "2-inch Micro CTD" model. This CTD type is referred to operationally as the HS_CTD. This CTD is fitted within an inductive type conductivity cell, a platinum thermometer and silicon pressure sensor.
The CTD temperature sensor is calibrated on the ITS-90 temperature scale against a master CTD using a controlled temperature bath. The pressure sensor is calibrated using a Druck Pressure Calibrator. The conductivity sensor is calibrated in a temperature controlled bath against seawater samples of known conductivity.
The HS_CTD is lowered and raised by a hand winch sampling at a rate of 1.83 Hz. Data files were recorded in the downcast and upcast direction but most data is from downcasts due to higher quality. Raw CTD pressure data is not always monotonic due to transient up/down motion of winch/ship. Raw pressure data is subsetted to give a monotonic (increasing) sequence and then linearly interpolated to 1 decibar pressure intervals and converted to netCDF format files. Data is then flagged with quality control flags after visual inspection and comparison to average climatology and historical CTD casts.

Assessment of the health of the Swan-Canning River System using Biochemical Markers of Exposure in Fish - Summary

The study focussed on the estuarine portion of the Swan-Canning River system, WA using the black bream (Acanthopagrus butcheri), an estuarine dependent fish species, as a biomonitoring tool.  Prior to the commencement of this study it had been determined that the black bream was a suitable fish species for use as a biomonitoring tool when using mixed function oxygenase (MFO) activity induction under laboratory conditions. Biopsies taken from feral black bream collected from eight sites during the period 2000 to 2002 from the estuary confirmed that the use of MFO induction in this fish species as a biomarker of exposure to organic contaminants is a reliable biomarker.

IMOS - Southern Ocean Time Series (SOTS) - Quality Assessment and Control Report - Remote Access Sampler: Sample Analysis, Macronutrient Analysis

This report details the quality assessment and control procedures applied to the macronutrient samples from the Remote Access Sampler deployed on Southern Ocean Flux Station (SOFS) and Pulse moorings between 2009 and 2018. The quality controlled datasets are publicly available via the AODN Data Portal. This report should be consulted when using the data. 
The Southern Ocean Time Series (SOTS) Observatory located at 140°E and 47°S provides high temporal resolution observations in sub-Antarctic waters. It is focused on the sub-Antarctic Zone because waters formed at the surface in this region slide under warmer subtropical and tropical waters, carrying CO2 and heat into the deep ocean, where it is out of contact with the atmosphere. This process also supplies oxygen for deep ocean ecosystems, and exports nutrients that fuel ~70% of global ocean primary production. The sub-Antarctic Zone and these processes are expected to change with global warming, but the potential impacts of these changes are not yet known.

Surveys of juvenile corals on the Great Barrier Reef using digital photography

The back reef habitats of three outershelf reefs (Ribbon Reef No. 10, at the Cod Hole, Chicken Reef and Turner Cay), one mid-shelf reef (Lizard Island) and one inshore reef (Great Keppel Island) were surveyed for juvenile hard corals between October 2006 and May 2007. Densities of juvenile corals were estimated by counting the number of colonies of &lt;50 mm diameter in a 34 x 34 cm (0.12 m²) quadrat with a scale bar attached. Between 7 and 33 haphazardly placed quadrats were sampled at each reef. All juveniles were assigned to one of two size classes (&lt;20 mm and 20-50 mm), which allowed the effects of colony size on detectability to be assessed. Juveniles were identified to the lowest possible taxonomic level, usually genus.Photographs of each quadrat were taken using an 8.0 megapixel Canon Powershot S80, except at the Cod Hole site where a 5.0 megapixel Canon Powershot A95 was used.Each quadrat was assessed by a single observer in the field and the image of each quadrat was assessed by two independent observers in the laboratory. No observer surveyed the same quadrat using both methods. The substrate in each image was rated from 1 (flat) to 10 (complex with many holes and crevices) to assess whether substrate complexity accounted for any differences between the two methods.
 This study was undertaken to investigate whether analysis of digital still camera images provided estimates of density and taxonomic composition of juvenile corals that were comparable to estimates obtained from visual census in the field.
