Fast Repetition Rate Fluorometry (FRRF) data collected on the RV L'Astrolabe from 28/10/2007 to 01/11/2007 (Hobart - Dumont d'Urville)

These data were collected on the RV L'Astrolabe (platform code: FHZI) from 28/10/2007 to 01/11/2007 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).

Lizard Island Sensor Float 4

A round 1.4m yellow buoy has been deployed in the western part of the main lagoon of Lizard Island to the south of the research station.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) and a SeaBird SBE37 measuring conductivity (salinity), temperature and pressure (depth).As of August 2010 the inductive sensors are located along a 50m cable that runs north into the main lagoon with a SBE39 located at the base of the buoy and the 37 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.

Temperature and the larval ecology of the crown-of-thorns starfish, Acanthaster planci, in northern Australia

Adult crown-of-thorns starfish were collected off Gove Peninsula near Nhulunbuy in the Northern Territory on 18 December 1991 and at Davies Reef in the central Great Barrier Reef on the 19th December 1991. The starfish were maintained at the Australian Institute of Marine Science laboratory in running seawater until experiments began in January 1992. Gamete shedding was induced by 1-methyl adenine injection and zygotes were transferred to rearing dishes at experimental temperatures within 5 minutes of fertilization at 24°C.Offspring of adults from both locations were reared in the laboratory at 21°C, 22.3°C, 24°C, 27°C and 31°C to examine geographic differences in development temperature tolerances. The development stage reached by embryos at each temperature was recorded. An experiment was also conducted to investigate a possible parental acclimatization effect in Acanthaster planci. Adults from Davies Reef were separated into two groups. One group was held for 18 days at 31°C and the other at 25°C for 21 days. Tolerance of the offspring of both groups to different temperatures was examined by observing the development of embryos at 18°C, 21°C, 22.3°C, 27°C and 31°C. Cleavage rates were also monitored for both experiments. Four replicate cultures in 20 ml scintillation vials (mean number of embryos per vial = 99) were fixed after 146 min. Embryos in each culture were counted and scored for cleavages completed. Possible parental effects due to seasonal change in water temperature in animals studied immediately after collection were examined. Starfish were collected at Davies Reef in October 1992 when the temperature at collection site was 25.5°C and in November when the temperature at the collection site was 27°C. The development of offspring of the two groups was observed at 21°C, 27°C and 32°C.Because of its importance to dispersal, the temperature tolerance of newly hatched, swimming early gastrulae was assessed. Early gastrulae from cultures of Gove embryos were transferred from 31°C to 31°C (control) for 2 days, 31° to 21°C for 5 days and 31°C to 18°C for 17 days. In December 1992, newly hatched gastrulae from starfish collected at Davies Reef were also transferred from 27°C to 27°C (control) and 27°C to 18.5°C. Davies Reef gastrulae were also transferred from 27°C to 15°C, held there for 6 days and then returned to 27°C. In all cases the development stage reached was recorded and reported as percent bipinnaria development.
 Laboratory experiments were used to investigate both the developmental temperature tolerances of offspring of geographically widely separated groups of Acanthaster planci and the effects of experimentally altering temperature exposures of adult, embryonic, and larval starfish.

Using settlement collectors to measure settlement intensity of echinoderms and other taxa at Davies Reef, Great Barrier Reef

Net bags containing 100 plastic biospheres were deployed at 6 sites, 300 to 500 m apart, on both the front (windward) and back (leeward) sides of Davies Reef. At each site, two pairs of bags, each 10 to 20m apart were deployed. Within each pair, the bags were placed 1 to 2 m apart.Samplers were deployed prior to the summer spawning season of Acanthaster planci and many other coral reef echinoderms. On recovery, each net bag was placed in a separate large plastic bag by divers. At the surface, water within each plastic bag was passed through a 0.1 mm sieve. Material from the sieve and the net bag of biospheres were frozen until sorting occurred. Three methods of sorting were trialled to determine which gave the best recovery of echinoderms for the least effort. The bucket technique, was to thaw the frozen samplers overnight in a 10 litre bucket of 99% alcohol. The bag was then shaken vigorously in the alcohol to dislodge any organisms. The contents of the bucket were strained through a 0.1 mm mesh screen and the material retained was then resieved through 3.5, 1 and 0.5 mm mesh screens. The three fractions were sorted under a stereo-microscope. Echinoderms retained on all three sieves were identified and counted. For other taxa, only organisms retained on the 3.5 mm sieve were identified and counted. In the rinse technique, alcohol preserved sampling bags were cut open to release the biospheres into a box with a 0.1 mm mesh base. The spheres were rinsed with a hose and the material left on the mesh was resieved and sorted as above. In the individual washing technique, spheres underwent the rinse technique and then each individual sphere was squirted with a hose to dislodge as much remaining material as possible. Material left on the 0.1 mm mesh was resieved and sorted as above.Only 10 randomly selected samplers were used for the comparison of sorting methods. All other samplers were subjected to the individual washing technique.Samples of rubble were collected from the sea bed during the same week that the settlement samplers were collected to examine naturally occurring levels of abundance of juvenile echinoderms in the benthic substrate. Collections were made at 4 sites on the front reef, reef flat and back reef. At each site, three boxes (26 x 18 x 8 cm) of rubble were collected and the contents later fixed in 4% formalin and sorted using the individual washing technique.
 This pilot study was initiated to evaluate the use of biosphere samplers to measure settlement rates of echinoderms and to allow analysis of spatial patterns in echinoderm settlement. Spatial and temporal variability in settlement rates may play a role in the widely fluctuating adult densities of some species, such as the crown-of-thorns starfish, Acanthaster planci and the burrowing sea urchin, Echinometra mathaei.

Quantifying the isotopic composition of oxygen and carbon with increasing depth in core GC11, located in the Capricorn Channel

A gravity core (GC11) was collected from a depth of 502 mbsl within the Capricorn Channel, southern Great Barrier Reef (GBR). The data from stable isotopes of Globigerinoides ruber were analysed to allow a preliminary understanding of the hemipelagic sedimentary environment over the last glacial / interglacial cycle. The results suggest that the core reaches the Last Glacial Maximum (LGM) at ~30cm depth. From matching the 18O G. ruber curve with Martinson et al. (1987), 4 glacial cycles can be determined, incorporating Marine Isotope Stage (MIS) 1 through to MIS 11. Isotopically heavier 18O values at ~460cm, ~345cm, 150cm, and 30cm correspond respectively to MIS 10, MIS 8, MIS 6 and the LGM. The d13C shows a trough lagging behind the 18O high during the glacial, although there are considerable fluctuations between MIS 8 and 6.

WAMSI 2 - Dredging Node - Project 5.2 - Genetic variability of seagrass in NW Australia

The aims of this study for the WAMSI Dredging Science Program were:

To establish fundamental knowledge on the genetic diversity of seagrass meadows; and if this varies among sites and with different environmental conditions, particularly clear and turbid water;
To understand the gene flow among populations; and
To inform the design of mesocosm and laboratory experiments on seagrass resilience.

This study was the first of its kind to examine the patterns of genetic diversity in seagrasses in the Pilbara region of WA. Three species were assessed: Halophila ovalis (6 populations), Halodule uninervis (8 populations) and Thalassia hemprichii (3 populations) at a range of spatial scales, within a meadow (centimetres−metres), among meadows at a local scale (2−60 km) and among meadows at a regional scale (up to 500 km). Due to the varied distribution of species we could not sample all species across the same spatial scale and range of environments, so we designed a nested approach, with sites replicated at a distance of 2−5 km, and then different species at varied larger spatial scales.

Surveys of reef-building coral communities, benthic cover and environmental factors on nearshore reefs of the Great Barrier Reef

Species richness, cover and community structure of reef-building corals were assessed at 599 sites on 135 reefs along the Great Barrier Reef (GBR) between 1994 and 2001, with a focus on the nearshore area. Reefs were surveyed using a standard method of Rapid Ecological Assessment.
On each reef, from 1 to 31 habitats were surveyed in up to 3 depth zones (sites), comprising (a) the shallow reef flat and crest; (b) the shallow reef slope (between 3 and 7m depth); and (c) the deeper reef slope (maximum depth of 16m) respectively. At each site, an inventory of reef-building corals was compiled.
Approximately 600 of the ~2,400 reefs of the GBR are located nearshore. The biological structure and ecological status of many nearshore reefs remain relatively poorly understood. This gap in knowledge was addressed by undertaking the first broad-scale assessment of nearshore reefs along &gt;75% of the length of the GBR focusing on patterns in the species composition, richness and community structure of reef-building corals.
Haphazardly-chosen starting positions were recorded with a portable Global Positioning System. The swims took an average of 45 min and covered varying distances along the slope; generally areas were surveyed until no new taxa had been encountered for some time. Corals were identified to species level wherever possible, otherwise to genus and growth form (e.g. massive Porites). At the end of each site survey, the abundance of each taxon was recorded in six broad abundance categories - absent, rare, uncommon, common, abundant, or dominant. A visual estimate of average cover of live hard coral was also made, recorded in 6 categories: 0=0%, 1=1-10%, 2=11-30%, 3=31-50%, 4=51-75%, 5=76-100%.
Data have been used for the e-Atlas:

Bioerosion of Porites corals in the central Great Barrier Reef

Sponge bioerosion was studied on three cross shelf transect reefs. 29 samples were used for the study, sourced from Myrmidon Reef, Rib Reef and Pandora Reef. Cross sections of Porites spp. were examined for bioerosion traces which were categorised by the appearance of the excavation patters by organisms (sponge, molluscs, worms and others). Occurrences of sponge bioerosion were further categorised according to architecture of the excavation pattern (porous, cavernous).  An analysis of the surface area of samples was conducted by an image analysis of each sample for live and dead surface. Subsequent collection of data for percentage of area removed and dead area on the corals, enabled a comparison between reefs and the sum of bioerosion with contributing factors.

Photographic documentation of some of the impacts of a 1-in-30 year storm on the ocean beach at Manly, NSW (8th June, 2007)

Friday 8th June 2007 saw a severe weather warning from the Bureau of Meterology. They warned of winds gusting to 90kph, flash flooding, waves exceeding 5m in the surf zone and significant beach erosion. It was dubbed a 30-year storm, and came as a costly reminder of the devasting power of the natural environment. These photographic images were taken on Wednesday 13th June and illustrate some of the impacts of the storm on Sydneys beaches, and the response of local councils in the clean-up effort. The photos illustrate aeolian sand in the backing reserves, the accumulation of sand around structures such as the sea-wall and beach access points, the physical removal of seaweed and wash-up onto shore, and the nourishment of North Steyne after the storm event.
