Redmap (New South Wales) - Sightings of Algae and Plant 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 email enquiries@redmap.org.au.

Seasonal changes in fecundity and fertility of the crown-of-thorns starfish, Acanthaster planci, from Davies Reef, Great Barrier Reef

Adult crown-of-thorns starfish (Acanthaster planci) were collected from Davies Reef between August 1990 and January 1992. Sampling was infrequent during the winter non-spawning period, but was as frequent as once per week during the spawning season. At each sampling, the gonad index of 10 male and 10 female starfish was calculated (gonad wet weight/total wet weight). During the winter, the total gonad weight was determined from the average weight of the gonads in three individual arms of a starfish, multiplied by the total number of arms. During the peak of spawning season (November to December), all gonads were dissected from starfish, since ripe gonads could not be assigned to a particular arm with a high degree of confidence.On seven occasions, between October and the end of January of the 1991-92 spawning season, experiments were carried out to examine fertilization rates and development success, using starfish collected from Davies Reef. All experiments were conducted under laboratory conditions either on land or on board a research vessel. Five male and five female starfish, identified by syringe biopsy were used in each experiment. Gonad tissue (1-3 g) was dissected from each animal and placed in 50 ml of .0001M 1-methyladenine in seawater for 30 minutes. The gonads were then removed from the solution and the concentration of gametes remaining (eggs and sperm) was determined in each of the containers. Counts of sperm were obtained using haemocytometers, while small plankton sorting trays were used to count eggs in aliquots from the original suspension. Suspensions of eggs or sperm from each starfish were then adjusted to concentrations of 3x10³/ml for sperm and 3x10²/ml for eggs. Sperm from each male was crossed with eggs from each female. Controls for sperm contamination were prepared using eggs alone with no additional sperm added. For each cross eggs, or eggs and sperm, were placed into three replicate 20 ml glass scintillation vials. The proportion of fertilised eggs was scored 2 hours after the addition of sperm. All eggs with fertilization membranes were scored as 'fertilized'. Approximately 100-150 eggs were counted. The vials containing the eggs were then resealed and re-counted 24 hours later. Eggs or embryos (100-150) were scored as either 'gastrula', if they had developed a definite archenteron, or 'non-gastrula', where this invagination was lacking or where fertilization had not occurred.
 Experiments were conducted to determine whether there was a systematic decrease in fecundity (measured as gonad index) and fertility (measured as fertilization rate) of Acanthaster planci through the spawning season.

Passive acoustic analysis of vessel presence in Australian Marine Parks

Monitoring compliance and enforcing laws are integral to ensuring the success of marine protected areas (MPAs), but traditional monitoring techniques are costly and resource demanding.
With the addition of many new marine parks to the Australian Marine Parks (AMPs) estate, there is a gap in the Director of National Parks’ understanding of use of AMPs by small vessels. This lack of ‘domain awareness’ creates a potentially high risk for marine park managers. 
The objective of this project is to improve our understanding of use of AMPs by small vessels and to inform compliance risk planning and management. To do this, archival acoustic recorders have been deployed in high risk parks. The data is analysed to gain an understanding of the level of small vessel activity in the AMPs.
Further deployments will be detailed within this metadata record as they occur.
Cod Grounds and Solitary Islands Marine Parks - Deployment 1
Three SoundTrap 300 recorders were deployed for one month between 1 July and 12 September 2018 to collect acoustic data in two marine parks off south-eastern Australia: one recorder in Cod Grounds Marine Park (CGMP) and two in the Solitary Islands Marine Park National Park Zone (SIMP NPZ). Approximately 12.7 hr of vessel sounds were recorded within CGMP; approximately 3.8 hr of vessel noise were recorded within the SIMP NPZ.

Comparative marine biodiversity survey of the Rowley Shoals

A major marine biodiversity survey of the Rowley Shoals, led by the Australian Institute of Marine Science in collaboration with the Western Australian Department of Environment and Conservation, was undertaken from 1-17 December 2007. The multidisciplinary survey aimed to collect data that could directly inform management of the Rowley Shoals Marine Park and the Mermaid Reef National Marine Nature Reserve. Three major research projects:
*  quantitative estimate/description of the condition of benthic communities of the Rowley Shoals by resurveying long-term benthic monitoring sites, and by quantifying the reefs' algal and soft coral biodiversity.
*  Quantitative survey of stocks of commercially important invertebrates  holothurians, Trochus and giant clams.
*  Reef shark habitat use through acoustic tagging.

WAMSI Node 6.2 - The Impact of tides and internal waves on offshore engineering - field measurement program - 70 km NW of North Rankin platform

The IWAG (Internal Wave Boundary layer Generation) instrument was deployed from October 23, 2008 to November 11th, 2008, on the NWS offshore from North Rankin A (NRA) in 420 metres of water.  
The field experiment involved the deployment of 29 moored Seabird temperature sensors (SBE39), 1 Seabird conductivity-temperature-pressure sensor (SBE37-CTD), as well as 5 Nortek Acoustic Doppler Velocity meters (ADV) to observe differences in BBL properties during the 14 day spring-neap tidal cycle. 
The 5 ADV’s measure velocities at a point in space in all three spatial directions and pressure at frequencies up to 64Hz. The ADVs were each synchronized with a co-located temperature sensor, permitting the calculation of turbulent heat fluxes in addition to a multitude of other turbulent properties.
Vertical extent was between 390 metres and 420 metres below Mean Sea Level.

RAN CTD Profile Data - HMAS MERMAID ProjectID: HI502MER_M From: 2011-07-08 To: 2011-09-11

This dataset contains quality controlled vertical profiles of pressure, temperature and salinity measured by a Conductivity, Temperature and Depth (CTD) probe. The dataset contains 101 CTD profiles (casts) obtained during RAN Hydrographic Survey cruise HI502MER_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.

Theme 1A: Ecological pattterns and processes on intertidal and subtidal rocky habitats

Research is focussed on the processes causing and maintaining patterns of distribution and abundance of animals and plants in coastal habitats (Program 1 - Ecology in Coastal Habitats). Without a good understanding of the ecology of species in these habitats, the interactions among the species and the relationships among patches of similar or different habitat, it is not possible to solve problems in the management of coastal change.
The assemblages of species on rocky shores and subtidal surfaces have long been important for developing methods and theories in general ecology. The animals and plants are very diverse, but many of them are abundant, relatively small and not too long-lived (on average) so that they allow direct experimental tests of predictions derived from ecological models and theories.
The Centre for Research on Ecological Impacts of Coastal Cities (EICC) has generated many scientific papers and theses from research projects on intertidal and subtidal rocky shores. The link to the URL provided in this record provides a link to this research.

Haemolymph protein in xanthid crabs from the Great Barrier Reef

Haemolymph was obtained from 26 xanthid crabs collected at low tide from Reef 21-145 and Laver's Cay on the Great Barrier Reef. A combinatin of protease inhibitors (5 mM EDTA, 1 µM pepstatin, 1 µM aprotonin and 100 µM phenylmethylsulfonyl fluoride) was added to the haemolymph. Measurements of equilibrium 3H-STX-binding, time courses of dissociation and association, and the pH-dependence of 3H-STX-binding was conducted on the crabs. Species were: Lophozozymus pictor (2), Liomera tristis (3), Chlorodiella nigra (2), Actaeodes tomentosus (2), Atergatis floridus (15), and Platypodia granulosa (2).Rat-brain synaptosomes were prepared from postmortem rat-brain tissue and binding assays conducted. Tissue extracted from each crab tested for 3H-STX-binding activity was then assayed for paralytic shellfish toxin (PST) activity by rat synaptosome.
 To report the discovery of a soluble and apparently proteinaceous 3H-STX-binding factor in the haemolymph of several species of xanthid crabs.To describe the attributes of this haemolymph factor in relation to saxiphilin and the sodium channel and to test its ability to bind tetrodotoxin (TTX) and saxitoxin (STX).

Sampling of planktonic microorganisms for metagenomic, metaproteomic and metatranscriptomic analyses

Large volumes of water (200 - 500 L) were filtered and fractionated by size for various planktonic components: eukaryotic phytoplankton, prokaryotic picoplankton, and marine viruses.  Sample sites were chosen to generate the widest diversity, and included planktonic blooms, oligotrophic zones, small polynyas near sea ice, nearshore areas, and Antarctic bottom water from coastal, canyon and deepwater areas.  Half of each sample will be used for DNA library construction, and the other half will be used for meta-proteomic analysis.  Random shotgun sequencing of the marine genomic libraries should produce a metagenomic snapshot of planktonic life in a variety of marine habitats. 
This work was completed as part of ASAC project 2899 (ASAC_2899).
