Myrmidon Reef currents and sea level data, Great Barrier Reef (1985)

An array of oceanographic instruments was deployed at six stations in the vicinity of Myrmidon Reef between January 1985 and May 1985. A tide gauge was deployed at Arab Reef, south west of Myrmidon Reef (MYR1). Three tide gauges were deployed on Myrmidon Reef (MYR2, MYR3, MYR4). Two current meters were deployed on a single mooring to the west of Myrmidon Reef (MYR5) and two current meters were deployed on a single mooring to the south of Myrmidon Reef (MYR6).

Reproductive potential of the long spined sea urchin Centrostephanus rodgersii in Tasmania

Recent poleward range expansion of the barrens-forming sea urchin Centrostephanus rodgersii (Diadematidae) from mainland Australia to Tasmania, has emphasized the need to understand the population dynamics of this ecologically important species in Tasmania. 
This work informs potential population dynamics of C. rodgersii in Tasmania by examination of its reproductive ecology. Reproductive periodicity (gonad index and propensity to spawn) was assessed bimonthly for 18 months at 4 sites in eastern Tasmania. Gamete viability was assessed by fertilization and early development trials.  Temperature tolerance of Tasmanian C. rodgersii larvae was also assessed to determine whether this species has undergone an adaptive shift to the cooler Tasmanian environment. There was also no evidence for an adaptive shift in reproductive phenology. Reproductive phenology was assessed by determination of peak spawning period (gonad index analysis).

Time series photography of Great Barrier Reef corals

In 1980, thirty permanent photographic sites were established on 6 reefs in 2 separate regions of the Great Barrier Reef. In 2001 an additional reef location was examined. Since 1980 the sites have been photographed annually to document fine-scale changes to the reef environment in a variety of habitats over an extended period of time. The last survey undertaken was in June-July 2007.The sites have been impacted by a number of disturbances including crown-of-thorns starfish, bleaching and cyclones. Analysis of the images reveals information about the extent and long term effect of each disturbance. Other aspects of the coral reef such as community type, diversity, succession, spatial interaction, species growth rate and resilience can be explored.
 To document fine-scale changes to the reef environment in a variety of habitats over an extended period of time.
 In the northern Great Barrier Reef region, 5 sites were established on the fringing reef of Lizard Island at depths between 2m and 13m and 8 sites were established on Yonge Reef at depths ranging from 2m to 38m.In the central Great Barrier Reef region a total of 17 sites were established on Pandora, John Brewer, Rib and Myrmidon Reefs.2 additional sites were established at Nellie Bay, Magnetic Island in December 2001 to document bleaching.The sites were photographed using 2 cameras to produce a stereo or 3-D image. Utilising 3-D software it is possible to make accurate measurements of individual corals, create spatial maps and track the fate of selected corals through time.

RAN CTD Profile Data - HMAS MERMAID ProjectID: HI546MER_M From: 2014-01-15 To: 2014-02-04

This dataset contains quality controlled vertical profiles of pressure, temperature and salinity measured by a Conductivity, Temperature and Depth (CTD) probe. The dataset contains 47 CTD profiles (casts) obtained during RAN Hydrographic Survey cruise HI546MER_M from HMAS MERMAID.
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.

Long-term Monitoring of Benthic Communities at Ashmore Reef 2016-2017

The Ashmore reef system, near the edge of north-western Australia&#39;s continental shelf, is isolated from the mainland and other reef systems by hundreds of kilometres of ocean. Existing studies show that the reef&#39;s communities and their distubance regimes differ from those at the Scott Reef and Rowley Shoals systems to the south. Ashmore Reef has vast areas of reef flat and shallow lagoon dominated by hard substrate, rubble, sand, and a low cover of other benthic organisms (e.g. sponges, soft corals, algae). The primary coral habitat is at the outer reef crest and reef slope.

Raw counts of diatom species in 18 surface samples collected during the French PACIMA- and Antarctic CRC (South Tasman Rise)- cruise missions

Diatom distributions in the polar regions have been attributed to physical and biological processes. To contribute to an existing diatom database (Pichon et al. 1992), 18 sediment surface samples were taken from the French PACIMA- and Antarctic CRC (South Tasman Rise) cruise missions. These samples were then prepared so that the diatoms could be identified and counted.
This dataset provides the raw diatom counts for the 18 surface samples collected.

Lizard Island Sensor Float 3

A round 1.4m yellow buoy has been deployed in the eastern part of the main lagoon of Lizard Island.The buoy is configured as a sensor-float with a Campbell Scientific logger, spread-spectrum radio and 2.4/5 GHz 802.11 wireless for communicating with the base station (located at the workshop near the Research Station) a surface mounted (60cm under the water surface) thermistor and an inductive modem to support a range of inductive sensors, initially this will be a SeaBird SBE39 measuring temperature and pressure (depth).As of August 2010 the inductive sensors are located along a 30m cable that runs north into the main lagoon with a SBE39 located at the end of the sensor run.The unit will be serviced every six months and will be used in the future for attaching new sets of sensors.
 The buoy is one of four buoys and two relay-poles being deployed on Lizard Island as part of the GBROOS Project. The design looks to measure the water within the lagoon as well as water impinging onto the reef and potentially any upwelling or movement of warm water that may cause thermal stress such as coral bleaching. The buoys initially have a Campbell Scientific loggers powered off four 5W solar panels, a wind turbine and one thermistor located at the base of the buoy around 60cm below the water line. The buoys use a Campbell Scientific spread-spectrum radio as well as 802.11 Wi-Fi to talk back to Relay Pole 2 and then to Replay-Pole 1 and then to the Base Station.

Zooplankton dynamics in mangrove and other nearshore habitats in tropical northeastern Queensland

Zooplankton was sampled in a mangrove forest, a mangrove drainage creek, the main stream of a mangrove dominated estuary, a seagrass flat at the entrance to the mangrove estuary and at an offshore (10 km) station in northeastern Australia approximately every 6 weeks between April 1985 and February 1986. Copepods, in particular Parvocalanus crassirostris, Paracalanus spp., several species of Oithona and Euterpina acutifrons were numerically dominant. Community structure often differed amongst mangrove habitats but mangrove habitats clustered separately from seagrass and bay habitats in classification analyses due to the abundance of meroplankton taxa, particularly invertebrate eggs and brachyuran zoea, in mangrove habitats. Total densities of zooplankton in mangrove and seagrass habitats were always higher than in the offshore bay habitat. Mangrove and seagrass habitats exhibited marked seasonality in densities of most taxa. Generally, seasonality in most taxa did not correlate with water temperature, salinity, mangrove litter fall or fish predation, although fish may have a significant influence on brachyuran zoea. There were often significant tidal variations in densities in mangrove creeks; low-tide densities were usually lower than high-tide values. Comparisons of the density of major prey taxa of fish in seagrass and mangrove habitats gave only partial support to the hypothesis that mangroves are more important nursery sites for zooplankton feeding juvenile fish because they are areas of greater food abundance; during the summer recruitment period of juvenile fish, brachyuran zoea, a major prey of fish, were an order of magnitude more abundant in mangrove habitats.
 This research was undertaken to investigate zooplankton dynamics in mangrove and other nearshore habitats and to test the hypothesis that between habitat differences in the densities of juvenile zooplankton feeding fishes reflect differences in the standing stock or taxonomic composition of zooplankton in these habitats.
 The mangrove forest site was sampled using a specially designed floating pump system (EZY-ZOOP). A boat-towed net (50cm diameter mouth, 105um mesh and fitted with a General Oceanic flow meter) was used to sample daytime zooplankton in the mangrove creek, mangrove mainstream, seagrass and bay habitats. Sampling was carried out using 5 minute oblique tows.

IMOS - National Mooring Network - South Australia Mooring Sub-Facility

The Southern Australia Moorings Sub-Facility is part of the National Mooring Network Facility.
This sub-facility is establishing a national reference transect of moorings and measurements off South Australia, which includes all parameters measured by the IMOS National Reference Stations (NRS).
The South Australia moorings sub-facility is based at the South Australian Research and Development Institute in Adelaide and is responsible for a total of five moorings. These moorings are deployed to continuously monitor the large seasonal coastal upwelling of water that occurs along the region's continental shelf during summer. This upwelling brings cold, nutrient rich waters onto the shelf which boosts primary productivity, creating one of the most productive coastal marine ecosystems in Australian waters. The five moorings measure an array of physical and biological properties and are a combination of four regional moorings and a National Reference Station (biological sampling at SAM5CB, SAM8SG, SAMGSV, SAMUSG and NRS).
The regional moorings consist of one shelf mooring located on the same isobath as the NRS and in the path of the upwelled/downwelled exchange, a mooring located near the mouth of Spencer Gulf to measure possible winter outflow of saline rich water, and two moorings situated in Upper Spencer Gulf and Gulf St Vincent. The NRS is located at a convergence point of isobaths and monitors upwelling and outflow events as well as long-term variations in the strength of the coastal current.
There are six discontinued moorings that were once part of this sub-facility, for which data is still available: M1 Deep Slope Mooring (SAM1DS) and M6 Investigator Strait Mooring (SAM6IS) were both discontinued in 2009, M4 Canyon Mooring (SAM4CY) and M2 Cabbage Patch Mooring (SAM2CP) were both discontinued in 2010, and M4 Mid-Slope Mooring (SAM3MS) and M7 Deep-Slope Mooring (SAM7DS) which were discontinued in 2013-2014.
