Exmouth Gulf Prawn Sustainability

Fifteen vessels are licensed to trawl for prawns in the Exmouth Gulf Prawn Managed Fishery. However, only 13 vessels fished, with the net headrope from the two retired vessels redistributed amongst five active trawlers, allowing them to tow 4.5 fathom quad gear. The fleet headrope length has been adjusted not to exceed previous effort levels with fewer boats and 6 fathom of headrope was unused.
The species caught are king prawns, tiger prawns, endeavour prawns and banana prawns. The king and tiger prawn stocks are fully exploited. Total landings of major penaeids for the 2003 season were ~1,089 tonnes, an increase on the very low catches seen in 2000. The tiger prawn catches have improved since the very low catch taken in 2000 due to Cyclone Vance and is now within the acceptable catch range for the species.
Project and activity description
Building up and maintaining an adequate spawning stock of tiger prawns is imperative in the Exmouth Gulf prawn fishery. This requires close monitoring of the catch rates of tiger prawns during the fishing season and closure of areas when catch rates fall below a threshold limit.
Analysis of the improvement in the efficiency of the current fleet with the move from twin to quad gear has been completed and a new appropriate catch rate threshold is used to ensure that tiger prawn spawning stocks are not overfished.
In recent years, the seagrass abundance has been monitored at key sites as this important habitat for juvenile prawns was severely damaged by Cyclone Vance in 1999.
The project provides:
* an overview annual report on the status of the Exmouth Gulf Prawn Managed Fishery;
* management advice as to the long-term sustainability of the Exmouth Gulf Prawn Managed Fishery;
* research directed to maintain Exmouth Gulf prawn resources at ecologically sustainable levels and to maximise economic and social benefits from this fishery ; and
* a smaller project involving monitoring of seagrass regenerations and establishment of a long-term monitoring system and sites.

There is an intensive program of liaison with Industry representatives and fishers as part of our logbook and survey/monitoring program.
Time: ongoing.

Davies Reef Sensor Float 2

A round 1.4m yellow buoy has been deployed in the Davies Reef lagoon as part of the sensor network infrastructure at Davies Reef in the central Great Barrier Reef off Townsville, Australia.
The buoy is configured as a sensor-float with a Campbell Scientific logger, a spread-spectrum radio for communicating with the on-reef wireless network, a SeaBird Inductive modem and initially a surface mounted (30cm under the water surface) thermistor and bottom mounted SeaBird SBE39 (temperature and pressure).
The project looks to deploy sensor networks at seven sites along the Great Barrier Reef to measure a range of physical parameters at a range of scales. The project will install communications, data and platform infrastructure that will support future sensor work looking at biological and chemical parameters.

RAN CTD Profile Data - SMB FANTOME ProjectID: HI446(C)FAN_H From: 2009-01-20 To: 2009-02-15

This dataset contains quality controlled vertical profiles of pressure, temperature and salinity measured by a Conductivity, Temperature and Depth (CTD) probe. The dataset contains 52 CTD profiles (casts) obtained during RAN Hydrographic Survey cruise HI446(C)FAN_H from SMB FANTOME. 
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.

Sonde data measured during a high rainfall event in Port Jackson, 23 August 2007.

The Sydney Harbour catchment area includes a number of different river systems which drain into the Port Jackson estuary. During high rainfall events the catchment areas behave differently to deliver contaminants into the Port Jackson estuary. Under conditions of high rainfall contaminants are delivered to areas very quickly as freshwater slides over the top of the denser more saline waters of the estuary. Sonde samples, for measurement of conductivity, salinity, turbidity and temperature; were taken along the Port Jackson estuary over three days to determine the behaviour of the freshwater plume as it travels in a layer of freshwater to be flushed or flocculate out at some point in the estuary.

Fast Repetition Rate Fluorometry (FRRF) data collected on the RV L'Astrolabe from 30/12/2004 to 04/01/2005 (Hobart - Dumont d'Urville)

These data were collected on the RV L'Astrolabe (platform code: FHZI) from 30/12/2004 to 04/01/2005 on a trip from Hobart to Dumont D'Urville.
Maximum photochemical efficiency of photosystem II (PSII), also called maximum quantum yield of PSII (Fv/Fm), has become one of the most widely utilized fluorescence parameters in phytoplankton research. It represents the potential photochemical efficiency, which is the probability that the light energy captured by the photosynthetic apparatus is being utilized as photochemistry. Fv/Fm has been shown to have an instant response to variations in physical and chemical properties and is interpreted as a diagnostic of the overall health or competence of phytoplankton. Together with the absorption cross section area of PSII and chlorophyll concentration, it can be used to measure primary production (Cheah et al. 2011, Deep Sea Research).
Seawater from 3 m depth was supplied continuously from the ship’s clean seawater line. FRR fluorescence yields were measured continuously at 1 minute intervals in dark-adapted state (! 15 minutes dark-adaptation) using a flash sequence consisting of a series of 100 subsaturation flashlets (1.1 μs flash duration and 2.8 μs interflash period) and a series of 20 relaxation flashlets (1.1 μs flash duration and 51.6 μs interflash period).

The hydrodynamic regime at John Brewer Reef, Great Barrier Reef: Mooring CM3: Current Meter

An Aanderaa RCM current meter was attached to mooring CM3, which was deployed in 40m of water. Deployment Details:Date Deployed: 3/4/1987Date Recovered: 5/9/1987Instrument Deployed:RCM #6021; Depth: 20m
 The aim of this project was to collect field data to calibrate a numerical model for the combined tidal and wind-forced circulation at John Brewer Reef, and to apply those circulation patterns to calculate the trajectories, residence times and likelihood of outbreaks of crown-of-thorns starfish on areas of the reef.
 The model boundary was defined by CM1, CM2, CM3, CM4, CM5 and CM13. However, the current meters attached to moorings CM5 (deployed 2/4/87) and CM13 (deployed 1/4/87) were not recovered. Mooring CM4 (deployed 2/4/87)drifted to the Whitsunday Islands. The current meter was badly fouled and the data were unusable.The transect CM3, CM8 and CM9 was laid to investigate the interaction between John Brewer Reef and Lodestone Reef. These reefs are only 7km apart and by studying both reefs at the same time it was possible to consider inter-reefal recruitment of crown-of-thorns starfish as well as self-seeding. The current meter attached to mooring CM9 (deployed 3/4/87) was not recovered.

WAMSI 2 - Kimberley Node - Project 2.2.2 - Pathways to Production: Biogeochemical Processes in Kimberley Coastal Waters

One of the few remaining pristine coastal environments in the world, the Kimberley is highly valued for its biodiversity, cultural values, tourism and fisheries. The biodiversity of the Kimberley coast is fuelled by oceanic and terrestrially derived nutrient resources, yet there has been limited prior research about how nutrients vary or how they are used and recycled across the region. Building this understanding is essential to inform future management of the Kimberley coast and marine parks.
This project has therefore been undertaken to address both of the major research priorities emphasised in the Kimberley Marine Research Program Science Plan: (a) providing the bio-physical characterisation required for marine resource management and (b) improving understanding of ecosystem function and how this might change in response to future trends in human use. In particular, this project has aimed to elucidate the processes controlling carbon and nutrient flows through pelagic ecosystems in the Kimberley region. Specifically, we have sought to link physical processes and riverine inputs to food web structure and function, improving process understanding of pathways and material flows that connect habitats, populations and bioregions in the Kimberley. We have identified sources of nutrients and how they translate to productivity for consumers, and through this work have supported the development of an improved understanding of how such processes may be modified by a changing climate.

Owner Advantage in the fiddler crab, Uca mjoebergi. Are owners more motivated than floaters in response to high quality territories?

Resource owners generally win contests against intruders, a phenomenon referred to as the 'Owner Advantage' (OA). Uca mjoebergi is a typical fiddler crab that is highly sociable, territorial and lives in mixed sex colonies on intertidal mudflats. Burrows are used in territory defence, for mating, and as refuge from predators and environmental stresses. Fights are common between owners and floating males who battle for ownership of the territory and burrow. 
Experiments were conducted from 28th Sept - 30 Dec 2006 at the lower reaches of Ludmilla Creek within East Point Reserve, 5km North of Darwin, NT. Previous experiments have revealed that owners win more contests than floaters because they are more motivated. This experiment was designed to test if owners are more motivated than floaters in response to high quality territories.
The results revealed that owners won more contests in 'high quality' territories than in 'natural' territories but this difference was not significant. Although owners win more contests in 'High quality' territories, the lack of significance may indicate only a small asymmetry between owners and floaters. It is possible that owners and floaters have similar abilities to perceive the food availability and be similar in motivational level.

RAN CTD Profile Data - HMAS PALUMA ProjectID: HI570PAL_M From: 2015-05-10 To: 2015-07-06

This dataset contains quality controlled vertical profiles of pressure, temperature and salinity measured by a Conductivity, Temperature and Depth (CTD) probe. The dataset contains 97 CTD profiles (casts) obtained during RAN Hydrographic Survey cruise HI570PAL_M from HMAS PALUMA.
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.
