Water circulation around Britomart Reef, central Great Barrier Reef (July 1979)

A comprehensive study of the hydrodynamics of Britomart Reef was carried out over a 3 week period in July 1979. An Aanderaa RCM4 current meter was deployed 1.2 m above the seabed in 30 m of water at each of the deep passes south (Site 1) and north (Site 2) of Britomart Reef. Data were recorded at 10 minute intervals for 3 weeks.Aanderaa RCM4 current meters were also deployed 1.2 m above the seabed at the western entrance to the reef (Site 3), 100 m inside the lagoon from the northern reef flat (Site 4), in the pass between the central and western lagoons (Site 5) and at the southern entrance to the reef (Site 6). Data were recorded at 10 minute intervals for 10 days. Data from sites 5 and 6 are incomplete.A continuous recording Marinco Q-15 current meter was suspended from a frame at a depth of 90cm above the bottom on the southern reef flat, 100m from the reef edge (Site 7) for 1 week. Another Marinco Q-15 current meter was suspended 1.5m from the surface from a vessel at the northern entrance (Site 8) for one tidal cycle.A Microdata weather station was mounted on a 10m tower erected on the reef flat between the western and southern entrances (Site O). Data were recorded every 10 minutes. Additional weather data from the Townsville airport were provided by the Commonwealth Bureau of Meteorology.Three stilling wells were installed beside towers erected approximately 200m apart from the reef edge to the lagoon, across the southern reef flat in the vicinity of Site 7.Curtain drogues (2m wide x 2m deep), suspended from a surface float connected to a buoy fitted with a radar reflector were deployed in the western lagoon and tracked by radar at half-hourly intervals.Microscale currents over the southern reef flat were studied qualitatively by observing the movement of dye released at 5 locations between the southern entrance and Site 7.The surface temperature field in the area was mapped using infra-red photographs from the Nimbus-N satellite.
 This research was initiated to collect hydrodynamic data from around Britomart Reef in order to assist in other scientific investigations.

Serpent Project Enfield 5 - Measuring megafaunal abundance, diversity and distribution.

Scientific and Environmental Remotely operated vehicle (ROV) Partnership using Existing iNdustrial Technology (SERPENT) ran a highly successful mission including 7 days of ROV operations.  Eight video transects were completed, for megafaunal abundance, diversity and distribution in the area.  Transects were conducted every 450 metres and extend to 100m from the drill site. Videos will be analysed for megafaunal diversity and habitat mapping during 2006.  
There is only one habitat type at ENC03, soft bottom. There is no evidence of any rock formations or hard bottom of any type.  ENC02 was approximately 30m away from ENC03 so there was some overlap in drill spoil. This will be accounted for when analysing video transects. Preliminary analysis indicates a high density and diversity of megafauna. The main component of the megafaunal community is consistent with soft bottom communities and includes echinoderms (asteroids, echinoids) a host of crustaceans (prawns and large isopods), eels that live in the sediment and some bottom dwelling fish. At approximately 85m along each transect, sponge beds were evident. Further investigation on subsequent missions will identify the extent of these beds.
A variety of prawns, crabs, eels, amphipods, isopods and fish were attracted to the bait traps. Initial examination of the data suggests that there is a difference in the diversity of organisms that visit the traps (inside vs outside the drill spoil). Isopods, shrimp and eels only appeared to visit traps outside of the drill spoil. Further analysis will validate any trends in the data.
Species collected for determining the level of heat shock protein expression:

8 isopods kept alive in seawater once brought to the surface
4 isopods exposed to drill mud once brought to the surface
4 isopods exposed to copper sulphate once brought to the surface
1 hag fish outside of the drill spoil
3 isopods outside of the drill spoil
Numerous small (&lt;1cm) amphipods from both within and outside of drill spoil.

Summary of the Winter Coral Bleaching Event at Ningaloo Marine Park, July 2006

Mass coral bleaching events triggered by anomalously high seawater temperatures have been reported worldwide with growing frequency over the past two decades. However, the impacts of low temperature coral bleaching (winter bleaching) on reefs are less well known. The first major coral bleaching event recorded for Ningaloo Reef was a winter bleaching event in July 2006. The combination of cold air temperatures and aerial
exposure of corals due to a low spring tide and a high pressure system appeared to cause bleaching of shallow-water corals. Observations made during an aerial survey indicated that bleaching had occurred along the entire length of the Ningaloo Reef.
The most severe bleaching was recorded at Pelican Point, where approximately 83% of live hard coral was bleached. Bleaching was mainly restricted to shallow-water corals of back-reef and patch reef environments dominated by plate and corymbose acroporids. Submerged corals appeared to remain unbleached. To investigate the recovery of bleached corals, two surveys were undertaken at Coral Bay and Pelican Point. At Coral Bay, approximately 90% of bleached coral had recovered by 14 weeks after the event, and approximately 100% of bleached coral had recovered at Pelican Point 30 weeks after the event.
This report describes the recovery of corals after a winter bleaching event and provides information regarding the first major bleaching event to be observed at Ningaloo Reef, Western Australia.
The potential combination of both winter and summer bleaching occurring in one year at the same reef could result in an increased threat to corals and should be considered among the climate change projections for coral reefs at some locations.

Future Reef MAP - April 2013 (Southbound)

Data were collected as part of the FutureReef MAP project, a three-year project designed to monitor ocean chemistry along the entire length of the Great Barrier Reef. The Future Reef MAP project is funded by Rio Tinto Alcan and administered by the Great Barrier Reef Foundation, with an equal co-investment by CSIRO. The project is the first large-scale CO2 observing system established on the Great Barrier Reef using the Rio Tinto ship, RTM Wakmatha. The research is targeted at providing information on the CO2 uptake and the controls on ocean acidification change in the region. It is providing foundation data needed to assess the vulnerability of the GBR reefs to ocean acidification. This dataset contains quality controlled underway measurements of the fugacity of CO2, atmospheric pressure, and sea surface temperature and salinity. The data management and distribution of these data were supported by the CSIRO Carbon Collaboration Cluster and the Australian Coastal Ecosystem Facility.

Monitoring mangrove creek systems for prawn pond effluent effects in north Queensland

Surface water concentrations of ammonium, nitrite, nitrate, phosphate, DON, DOP, chlorophyll a, were sampled monthly in two tropical, tidally-dominated creeks in north Queensland for 30 months between October 1993 and May 1996. Climatic factors (rainfall and temperature), and physico-chemical information from the creeks (salinity, pH, DO, temperature) were analysed using ANOVA and multiple regression. Seasonal and climatic fluctuations were significantly correlated with fluctuations in several of the observed parameters. The dynamics of salinity at upstream and downstream locations in the creeks was the major factor which had a significant effect on the dynamics of the nutrient and chlorophyll a concentrations. Rainfall in the catchment area feeding these creeks is also significantly correlated with associated fluctuations in concentrations of dissolved nutrients and chlorophyll a. Natural fluctuations in climatic events, as demonstrated here, need to be taken into account when assessing the relative impact of human activities upon the same ecosystem..
 To identify potential environmental impact of prawn farm aquaculture discharge on adjacent tidal mangrove creeks and forests.
 This project was conducted under contract from Mossman Central Mill Co. Ltd. Research was centred on Muddy Creek adjacent to the Sea Ranch Pty Ltd prawn aquaculture facility.Additional information in database: monthly mangrove forest litter fall, mangrove soil salinity, mangrove soil nutrients.

SAIMOS - Biological and Flow Cytometry data collected from CTD stations in South Australia, in February 2013

Flow cytometry data was collected in February 2013, in waters off South Australia. 
The general purpose of the study is to be able to establish background knowledge on the ecosystem on the continental shelf of South Australia and the impact of upwelling/saline outflow events on microbial communities to ultimately develop a biogeochemical model of the region. Sampling was carried out during cruises conducted on board the RV Ngerin as part of the Southern Australian Integrated Marine System (SAIMOS). During each cruise, the physical, chemical and biological properties of the chlorophyll fluorescence maximum (DCM) layer were investigated. Flow cytometry data is normally collected for picophytoplankton, bacteria and viruses, but not on this cruise
Six main stations have been sampled over the course of the study, five are located on the 100 m isobath, i.e. RS (35.508S, 136.278E), B2 (35.418S, 136.148E), B3 (35.258S, 136.048E), SAM2CP/B4 (35.168S, 135.418E) and SAM5CB/B5 (35.008S, 135.198E), and one from an offshore station (B1; 36.188S, 136.178E) located southwest of Kangaroo Island. Note that combining the distances between stations (14–25 nautical miles), the average component of the current velocity at middepth along the shelf (0.01 m s21) and the average speed of the vessel (i.e. 9 knots) indicate that different water masses were sampled at each station. Additional samples have on occasion been collected from the National Reference Station (NRS) at Kangaroo Island (35.832S, 136.447E) and the SA Spencer Gulf Mouth Mooring (SAM8SG, 35.25S, 136.690E), where the saline outflow occurs.

Latrobe Valley Ocean Outfall (LVOO) infaunal monitoring program near 90 Mile Beach, Victoria

The LVOO outfall was commissioned in 1992 to discharge a mixed effluent of domestic sewage and industrial wastewaters, including pulp mill effluent and formation water from offshore oil platforms. This data was collected to assess the impact of the outfall on the surrounding soft sediment habitat. Infaunal samples were collected from an impacted location (Delray Beach) and two control locations (Woodside Beach and Seapray) at depths of 13 to 18 m. Each location (2km x 1km) was separated by at least 20km and consisted of eight random sites within each location. Sampling at each location was undertaken on four occasions between 1989 and 1994.

NESP TWQ Project 4.13 - Assessing the Gulf of Carpentaria mangrove dieback, 2018-2020 (JCU)

In early 2016, extensive dieback of mangrove forests was recorded along the southern and western Gulf of Carpentaria coastline. Landsat analysis suggests that 7,400 hectares of mangrove forest suffered dieback over a relatively short and synchronous time period around November 2015, along a &gt;1,000km wide front from Karumba in the east to Limmen River in the west. Recent field visits to a limited range of affected sites suggest that a relatively low percentage of trees have recovered and most are dying/dead. This is the largest event of natural dieback of mangroves ever recorded in the world. This project will provide a survey, description and analysis of the extent of the dieback across its range, as well as examining patterns of dieback. The assessment will include training and participation of local Indigenous ranger groups in mangrove assessment and monitoring methods, as well as providing recommendations for recovery, potential intervention, future monitoring and further studies. A synthesis workshop will also be held to present the findings of the assessment to a wide audience.

Freshwater impacts in the central Great Barrier Reef: 1648-2011

Coral cores of massive Porites were collected to assess the frequency of flood plume events extending beyond the inshore to mid-shelf reefs. A reconstruction of the Burdekin River flow from 1648-2011 was undertaken through examining the coral luminescence as a proxy for freshwater flood plumes in the central GBR. Measurements of the luminescent lines in slices from massive Porites Skeletons, viewable under ultraviolet (UV) light act as a proxy for the frequency and intensity for effects of plume events.
The analysis was conducted on cores slices 6-7mm thick, sourced from the nearshore reefs of Havanah Island: one long (~5 m) core collected in June, 1988, and four short (&lt;50 cm) cores collected in August, 2012; and from the mid-shore region of Britomart Reef: five short cores collected in May 2013. All core samples were taken from Porites colonies which were situated in water depths of less than 10m. Analysis included measuring luminescence intensity with AIMS&rsquo; custom-built gamma densitometer/luminometer. The luminescence range was calculated for each year, dating back from the collection of the core.
Records of daily and monthly river flow volumes for the Burdekin river, as well as rainfall records, were analysed for total annual river flow for the water year of October - September and use as a comparison of observed and reconstructed Burdekin River flow.
Coral Core IDs include:
Havanah Island: HAV01A, HAV31B, HAV32A, HAV33A, and HAV34A
Britomart Reef: BRT60A, BRT61B, BRT62B, BRT63A, and BRT64B

Does the sea divide or unite Indonesians? Ethnicity and regionalism from a maritime perspective: WORKING PAPER

This record describes, and links to a working paper produced through the Resource Management in Asia-Pacific (RMAP) Program based at The Australian National University in Canberra.

The Indonesian Government argues that the sea bridges the many islands and different peoples of Indonesia. Politically, this might be appropriate as a means of encouraging people to think that wherever and whoever there are, they are united as Indonesians. However, when this ideology is used for maritime resource management, it creates problems. One issue derives from the fact that people do not think that the Indonesian sea is 'free for all' Indonesians. I will argue that people, however vaguely, talk about 'we' and 'they' in defining who has the right to a particular fishing ground and who should be excluded. By analyzing conflicts that have taken part in different places in Indonesia, I will demonstrate that ethnicity and regionalism have been used as the defining factor of 'We' and 'They.' In particular contexts, ethnicity and regionalism define whether fishermen can access marine resources. Thus, at the practical level the sea does not unite Indonesians, and it is in fact, ethnicity and regionalism that divides the Indonesian seas.

Surveys of the ecological use of epibenthic habitat by fish in the central Great Barrier Reef using baited remote underwater video stations (BRUVS (TM)) (FRDC Project No. 97/205)

BRUVS (TM) were deployed at spatial coordinates known, from previous major studies using fish traps, to be "hot-spots" for the families Lutjanidae (sea perches), Lethrinidae (sweetlip emperors) and Serranidae (coral trout and cod).BRUVS (TM) were deployed at depths between 30 and 70 m in three mid-shelf locations (Davies Reef (9), Kelso Shoals (18), Rib Reef (9)) and in both shallow and deep inshore locations (Calliope Channel (14), Curacoa Channel (27), and Robbery Shoals (3)).Replicate BRUVS (TM), were deployed in daylight hours and the time, depth, latitude and longitude was recorded for each set.Interrogation of each tape provided:- a classification of the habitat at each set, based on estimated sediment composition and/or the nature of epibenthos- the time the BRUVS (TM) settle on the seabed (TOB)- the time of first sighting of a taxa (TFS)- a coarse classification of 'Adult' or 'Juvenile' for these taxa based on size and shape- the time of first feeding of taxa (TFF) in the field of view,- the maximum number of each taxa seen together, or readily identifiable, in any one time on the whole tape (MaxN),- the time at which this maxima occurred (TMaxN)- the behaviour of each taxa toward the bait (passing, scavenging, or feeding), and- the time at which all bait was exhausted if such an event occurred.The habitat categories recognised were: megabenthos, Sargassum, Halimeda, low algae, mud, fine sand, coarse sand, rubble, and 'near benthos'. The 'near benthos' category covered sets where video units landed on sand, but in the far field of view, or during the deployment or retrieval, significant patches of rock or megabenthos were seen.Image grabs also allowed size estimates of fish directly above the scale grid on the bait canister.
 Baited remote underwater video station (BRUVS (TM)) surveys were undertaken to investigate the relationship between fish requirements for food and shelter and the distribution of sponge, gorgonian and algal 'megabenthos'.The specific questions addressed were:1. what is the nature of fish communities inside and outside megabenthos patches?2. what benthos and sediments characterise some known 'hotspots' for inter-reef lutjanids?The results of the BRUVS (TM) surveys were compared with concurrent RUVS (unbaited) surveys, trapping and underwater visual census (UVC) as methods to census demersal fish.
 This research was a component of subproject 8, "The ecological usage of epibenthic habitat by key commercial finfish species", of the Fisheries Research and Development Corporation Project No. 97/205, "Dynamics of large sessile seabed fauna, important for structural fisheries habitat and biodiversity of marine ecosystems - and use of these habitats by key finfish species"
