Carbon and nitrogen budgets in shrimp ponds in mangroves of the Mekong Delta, Vietnam

Mass balance estimates of carbon and nitrogen flux through two extensive shrimp ponds in the Mekong delta, Vietnam, were constructed.Recruitment and losses of post-larval shrimp were estimated. Mud crab stocking and havest was estimated for the pond in which they occurred.Estimates were made of tidal water exchange and calculations of organic carbon and nitrogen inputs and outputs based on the exchange.Nitrogen input from precipitation was estimated by multiplying the annual average rainfall by the concentration of TDN in rainwater multiplied by pond area. Calculations of primary production were based on 14C uptake for water column, and oxygen flux in light and dark bottles for benthic respiration.Estimates of organic carbon and total nitrogen excavated from the ponds was made based on TOC and TN of excavated pond sediments.Estimation of sedimentation from water column to the pond bottom was made by measuring the rate of decline in TOC and TN of pond water over 1-2 days.Rates of ammonification, nitrogen fixation and nitirification were measured to construct sediment N budgets.
 To identify major sources and sinks of organic matter potentially available for shrimp production in tidally flushed ponds. To assess rates of decomposition and burial and quality of organic matter.
 Some preliminary estimates of shrimp production in mixed shrimp-mangrove forestry farms were made.

Effects of crown-of-thorns starfish (Acanthaster planci) outbreaks on coral community structure at John Brewer Reef and Rib Reef, Great Barrier Reef

Permanent transects, which were established in 1974 by RG Pearson (Queensland Fisheries Service) at two sites on John Brewer Reef after a crown-of-thorns starfish outbreak, were resurveyed using stereophotography (from a range of 1.8 to 1.9 m) on four occasions from 1980 to 1983. The 10 x 1m transects were located at 6 and 12 metres depth at Site A (on the southeast forereef slope) and at 3 metres depth at Site B (on the northern back reef slope). Coral identifications were made in the field.Colonies too small to be censused using photography and those hidden in the substratum were censused visually. Their positions were plotted throughout the 10 m² area of each fore-reef transect at 6 monthly intervals on three occasions commencing in November 1983, soon after a new starfish outbreak. The identity, maximum diameter and grid position of each coral located was recorded using a 1m² quadrat divided into a 5 x 5 grid of 20 cm squares, which was systematically searched, one square at a time, until all 10 square metres of the transect had been searched.A further 135, 0.25 m² quadrats were searched at other reef slope locations on John Brewer Reef and adjacent Rib Reef. Each quadrat was placed at random on hard substrate in areas where coral mortality was estimated to be in excess of 95% over hundreds of square metres. In these searches, genus and the abundance of each genus of surviving coral remnants was recorded along with depth and location.Massive corals &gt;= 10cm in diameter were surveyed in 1984 and the diameter of each coral and proportion of living tissue recorded. The categories used to describe the proportion of living tissue were: 0 living tissue. For colonies up to 60 cm diameter, the survey was made using a total of 1.8 km of line transects, in 50 m units at depths of 3, 6 and 9 m at 12 locations around John Brewer Reef. For colonies over 60 cm diameter, the survey consisted of 2.4 km of standard swims in 200 m units at the same 12 locations. In these swims, the reef slope was searched in a slow, meandering swim, down current, on scuba. The depth range searched was from 2 to 12 m. The line transect was assumed to sample a strip 0.3 m wide and the standard swim a strip 20 m wide. The results were standardized to number of individuals per 1000 m².
 This research was undertaken to:1. obtain quantitative data on the composition, abundance, density and size distribution of surviving corals after a crown-of-thorns starfish (Acanthaster planci) outbreak 2. define starfish damage to coral communities in a way that provides a basis for prediction of the ecological consequences of these outbreaks.

Role of zooxanthellae in the thermal tolerance of corals, Great Barrier Reef

The acclimatization potential of Acropora millepora was investigated through transplantation and experimental manipulation. Twenty-two colonies were sourced from each of a cool southern inshore reef (North Keppel Island) and a cool central offshore reef (Davies Reef) and transplanted to a warm inshore bay (Magnetic Island). A further 22 colonies from each of Magnetic Island, Davies Reef and North Keppel Island were kept at their respective 'native' reefs until their thermal tolerance limits could be experimentally tested together with the transplanted corals kept at Magnetic Island for 9 (Keppels) and 14 months (Davies).Corals were sampled for zooxanthella genotyping at the time of transplantation and again just before the temperature experiments. Zooxanthellae were identified based on the nuclear ribosomal DNA internal transcribed spacer 1 (ITS1) region using single stranded conformation polymorphism (SSCP) and sequencing analysis.Twelve nubbins (3-5 cm long) were cut from each of 6 colonies of A. millepora from each of 5 populations (Magnetic Island, North Keppel Island native, North Keppel Island transplants, Davies Reef native and Davies Reef transplants) and distributed equally among 4 temperature treatments (27.5, the non-bleaching control treatment; 30; 31 and 32°C each with 3 treatment replicates) in an indoor aquarium system.The fluorescence yield (dark-adapted) of zooxanthellae was measured using a Diving-PAM. Dead corals and white bleached corals that could not return a reliable yield were assigned a value of 0. Corals were designated healthy, bleached, dead.Data loggers have continuously recorded temperatures at half-hourly intervals at Magnetic Island since 1992, and at Davies Reef and Halfway Island (about 15 km from North Keppel Island) since 1995.
 To investigate the role of zooxanthellae in the thermal tolerance of the stony coral, Acropora millepora, in a large scale transplantation experiment.To show that thermal tolerance in this species is inextricably linked to the type of algal symbionts harboured. To show that individual corals can change their predominant algal symbiont types.To show that the potential for a change in algal symbiont may be population-specific and that increased tolerance resulting from symbiont change is limited inregard to expected future temperature increases.
 The first study to show thermal acclimatization is causally related to symbiont type.

Age vs Depth profile of core GC13, collected from the Capricorn Channel off the Eastern Australian Coast

A gravity core (GC13) was collected from a depth of 1482 mbsl within the Capricorn Channel, southern Great Barrier Reef (GBR). Isotopic values for 18-O and 13-C were obtained from Globigerinoides ruber and correlated with the SPECMAP age-model. The age-model that was produced plausibly extends back to Marine Isotope Stage (MIS) 6, with approximate sedimentation rates calculated according to this model. Sedimentation rates fluctuate from 5cm/kyr during the last transition and interglacial, to 1cm/kyr during the glacial maximum.

Redmap (Tasmania) - Sightings of Mammal Species

Redmap is a primarily a website that invites the community to spot, log and map marine species that are uncommon in their region, or along particular parts of their coast. The information collected is mapped and displayed on the site, demonstrating, in time, how species distributions may be changing.
Sightings are divided into two categories – those with a photo that can be ‘verified’ by a marine biologist, and sightings without photos that we call community sightings (anecdotal). All the information collected, with and without photos, is mapped and will be used in the following years to map out a ‘story’ of changes occurring in our marine environment.
The main data collected includes the species sighted (normally selected from a list comprising preselected species of interest), the location, date/time and activity being undertaken.  Other optional information gathered include biological data such as sex, size and weight and environmental data such as water depth and temperature and habitat.
This record is associated with live data (and will subsequently change over time) and spatial elements have reduced accuracy.  It is also subject to a three year embargo (ie. does not contain data less than three years old).  If you wish to discuss obtaining a citable, static dataset, that is current and/or contains accurate spatial elements, please see Point of Contact.

IMOS - Deep Water Moorings - Deep Water Arrays (DA) Sub-facility, East Australian deep water array, East Australian Current 1 Mooring (EAC1) Platform

The EAC1 deep water mooring was deployed in April 2012 at (-27.31 S, 153.98 E) off the Queensland coast, near Brisbane, Australia. The mooring was recovered in August 2013 and the array decommissioned, and a newly configured array (with new moorings) was redeployed in May 2015, and then subsequently decommissioned in July 2022. 
Instrumentation on the mooring includes 75kHz Acoustic Doppler Current Profilers (Long Ranger ADCPs), Seabird SBE37SMPs, temperature loggers (Star Oddi, Starmon Mini) and discrete current meters (Aquadopp 6000).
The mooring will collect a time series of full-depth profiles of water velocity and discrete temperature and salinity measurements. 
The array will consist of 9 current meter and property moorings extending eastward from the Queensland Coastal Node shelf mooring array near Brisbane to the deep ocean. The moorings will be at 500-600 m intervals across the Continental Slope and increasing to 800-1000 m in the deep ocean.  
The East Australian Current (EAC) is the major western boundary current of the south Pacific Ocean. It plays a critical role in the ocean re-distribution of global heat from the equator to the midand- high latitudes. The EAC is relatively stable north of Brisbane, but as the current moves south
2-3 large eddies are pinched off every year. These eddies frequently move onto the continental shelf and close inshore and influence the local circulation patterns. At prominent coastal features the EAC moves away from the coast, driving upwelling which draws nutrient-rich water from a depth of 200-m or more.

RAN CTD Profile Data - HMAS BENALLA ProjectID: HI537BEN_M From: 2013-06-20 To: 2013-07-16

This dataset contains quality controlled vertical profiles of pressure, temperature and salinity measured by a Conductivity, Temperature and Depth (CTD) probe. The dataset contains 312 CTD profiles (casts) obtained during RAN Hydrographic Survey cruise HI537BEN_M from HMAS BENALLA.
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.

NESP TWQ Project 2.1.7 - Engaging with farmers and demonstrating water quality outcomes to create confidence in on-farm decision-making (“Project 25”), 2016-2018 (JCU)

Recent global experiences suggest that spatially identifying and prioritizing landscape ‘hotspots’ of pollutant generation for management intervention, and small catchment-scale water quality monitoring in collaboration with landholders linking water quality with specific management practices, are among the most promising strategies for reducing water quality pollution. This project will combine recent hotspot identification in GBR sugarcane catchment of the Russel/Mulgrave with targeted cane farmer interaction activities (related to sub-catchment and localized monitoring activities), focusing on emerging monitoring technologies (real-time water quality monitoring) to link farmer on-farm practices with feedback from sub- catchment water quality measurements. The use of both scientific and citizen science monitoring approaches will deliver robust feedback loops to enable farmers to directly link their activities with water quality conditions. The project will focus on on-farm practice improvements in highest priority catchments to achieve maximum benefits to GBR health from catchment management actions.
