Effect of marine reserve status on coral seeding in the inshore Great Barrier Reef

In a 11-month field study, we deployed ex-situ reared Acropora millepora spat on  coral seeding devices across 6 sites (3 from &#39;take&#39; reserves open to fishing, 3 from &#39;no-take&#39; reserves closed to fishing) in the Keppel Islands Great Barrier Reef Marine Park (Woppabura sea Country, inshore, southern Great Barrier Reef, Australia). Two devices with fish-exclusion features (exclusion star and exclusion triangle) were tested against a control device (featureless control star). 
Mature gravid Acorpora millepora (Dana 1846) colonies were collected in November 2022 and transported back to the research vessel equiped with coral holding and spawning facilities. Gamete bundles were collected, separated, washed, fertilised, then  transferred to  larval rearing tanks where they remained until they reached settlement competency after 5-6 days.  Conditioned concrete tabs (14 &times; 14 mm2; developed under the Reef Restoration and Adaptation Program) were used as settlement substrates. The tabs contained a mixed community of crustose coralline algae and bacteria biofilms that are known to induce settlement of Acorpora corals; these were conditioned in aquaria (National Sea Simulator, AIMS, Townsville) for 2-months prior to spawning and settlement. 
Corals in devices were seeded to 6 sites, in one of the 13 experimental plots at ~4-6m depth (LAT). The hierarchical design included location (n=1), sites (n=6), experimental plots (n=13, 12 plots with 6 devices and 1 plot with 3), device type (n=3), contrete settlement tabs (n=3 for the exclusion star and control, n=6 for the exclusion triangle), and coral spat (n=~12 per tab) . Devices were semi-fixed in experimental plots (connected to reo bar via rope, with the reo hammered into the substrate) and hand placed by divers but had the potential to move within a given plot.  Material was removed after 11 months.
Data were collected at 4 timepoints and included quantitative and qualitative assessments to determine the influence of biological (fish abundance and feeding, benthic composition) and environmental (sedimentation, reserve status, site) drivers on coral survival and size.  Assessments were categorised and analysed by spatial scale: tab, plot, or site. Bayesian hierarchical logistic mixed-effects regression models, principal component and redundancy analyses were used to interogate the data. Please refer to the publication for more details on the statistical analyses.

Venom on Ice - data collected from the CEAMARC voyage of the Aurora Australis, voyage 3 2007-2008

Accompanying excel spreadsheet details the DNA samples taken and venom glands obtained and associated date/location/depth collection site data.
Each specimen will be DNA barcoded using the diagnostic 600bp region of the mitochondrial COI gene and sequences lodged on GenBank. DNA barcoding will aid in evaluating the extent of cephalopod biodiversity including revealing cryptic species and phylogeographic structure. Confirmation of species identities is also essential as glands from multiple individuals will be required for detailed proteomic analysis of the proteins produced by the octopus posterior salivary glands.  The chemical composition of the secretions will be determined through the application of multidisciplinary techniques, including cDNA library construction, mass spectrometry, molecular modelling and bioactivity testing.   The studies will commence in 2008 and run for several years, being the major element in a PhD project run through Dr. Fry's laboratory.

Coccolithophore species fluxes in the Australian and New Zealand sectors of the Subantarctic Zone

Coccolithophore fluxes were investigated over a one-year period at two sites of the Subantarctic Zone in the Australian and New Zealand Sectors of the Southern Ocean. The samples from the Australian SAZ were retrieved at the SOTS observatory, which lies in the SAZ (near 47°S, 142°E), approximately 500 km south west of Tasmania. SOTS was instrumented with three moored platforms: (i) a surface tower buoy that performs meteorological measurements (the Southern Ocean Flux Station - SOFS); (ii) a surface mixed layer mooring equipped with an automated water sampler) and nutrient, carbon and biological measurement sensors (the Pulse mooring); and (iii) a bottom-tethered deep sediment trap mooring that collects sinking particle fluxes for diverse biogeochemical studies (the SAZ mooring). The samples from New Zealand came from the deep-ocean SAM mooring deployed in Subantarctic waters south east of New Zealand (46°40’S, 178’ 30°E), and was equipped with sediment traps and a suite of sensors. Here, we report the coccolith sinking assemblages captured by sediment traps at ~1000, 2000 and 3800 m depth for a year from August 2011 until July 2012 at the SOTS observatory and a sediment trap at ~1500 m depth for a year from November 2009 until October 2010 at the SAM site. 
A description of the field experiment, sample treatment, determination of total CaCO3 content, and estimation of coccolith and coccosphere fluxes can be found in Rigual-Hernández et al. (2020a) and Rigual-Hernández et al. (2020b). 
Data available: two excel files (one for each station) containing sampling dates and depths, relative abundance of coccolith sinking assemblages, and coccolith, coccosphere and total CaCO3 fluxes. 
Detailed information of the column headings is provided below.
Cup – Cup (=sample) number

Population estimates of emperor penguins, Mawson coast, Antarctica

Metadata record for data from ASAC Project 484
See the link below for public details on this project.
---- Public Summary from Project ----
Emperor penguins are the only birds that breed in the Antarctic winter. They feed mainly on fish and squid but also ingest krill. Changes in food availability due to oceanographic or climatic factors, or to the extent of sea ice (through the processes of global warming) will have a direct impact on the breeding success and population size of the penguins. By counting the number of males that incubate at mid-winter each year, we can monitor trends in their population size. Counts of fledglings in spring (November) tell us how successful the penguins bred.
The download file contains an excel spreadsheet which presents a summary of known Emperor Penguin colonies in the area of the Australian Antarctic Territory (AAT), and a file which details counts of male emperor penguins at the Taylor Glacier colony.
A description of the column headings used in the spreadsheet is below.
Colony: Colony name
lat, long: latitude and longitude of colony
discovered: date colony was discovered
current est pop (BP): Current estimated population size in breeding pairs - current as at date the colony was last seen
last seen: date the colony was last seen
counting method: method used to count the breeding pairs in the colony
comments: any applicable comments
reference: references relating to the colony
Taken from the 2009-2010 Progress Report:
Public summary of the season progress:
Population size of colonies fluctuates which is why long term monitoring studies are necessary to detect trends. At the emperor penguin colony at Taylor Glacier, monitored continuously since 1988, a slight downward trend is apparent but is not (yet?) statistically significant. The colony was visited three times: once in winter to obtain an estimate of the number of adults in the colony (roughly equivalent to the number of breeding pairs), and twice during the late chick rearing season to estimate breeding success. The count of adults in 2009 was the lowest on record. Reasons for this are still unknown.

K-Axis mesopelagic fish DNA-based diet analysis

High-throughput DNA-sequencing data for mesopelagic fish stomach contents sampled during the Kerguelen Axis voyage (January-Februay 2016). 
Mesopelagic fish form an important link between zooplankton and higher trophic levels in Southern Ocean food webs, however their diets are poorly known. Most of the dietary information available comes from morphological analysis of stomach contents and to a lesser extent fatty acid and stable isotopes. DNA sequencing could substantially improve our knowledge of mesopelagic fish diets, but has not previously been applied. We used high-throughput DNA sequencing (HTS) of the 18S ribosomal DNA and mitochondrial cytochrome oxidase I (COI) to characterise stomach contents of four myctophid and one bathylagid species collected at the southern extension of the Kerguelen Plateau (southern Kerguelen Axis), one of the most productive regions in the Indian sector of the Southern Ocean. Diets of the four myctophid species were dominated by amphipods, euphausiids and copepods, whereas radiolarians and siphonophores contributed a much greater proportion of HTS reads for Bathylagus sp. Analysis of mitochondrial COI showed that all species preyed on Thysanoessa macrura, but Euphausia superba was only detected in the stomach contents of myctophids. Size-based shifts in diet were apparent, with larger individuals of both bathylagid and myctophid species more likely to consume euphausiids, but we found little evidence for regional differences in diet composition for each species over the survey area. The presence of DNA from coelenterates and other gelatinous prey in the stomach contents of all five species suggests the importance of these taxa in the diet of Southern Ocean mesopelagics has been underestimated to date. Our study demonstrates the use of DNA-based diet assessment to determine the role of mesopelagic fish and their trophic position in the Southern Ocean and inform the development of ecosystem models.

SRE4 Effects of hydrocarbons on Antarctic Marine Sediment Ecosystems - SRE4_Microbial

Sediment Recruitment Experiment 4 (SRE4) was a large, long term (5 year) field experiment run at Casey Station (from 2001 to 2006) testing the effects of 4 different hydrocarbons on marine sediment ecosystems. Four different types of hydrocarbons were individually mixed with defaunated marine sediments and deployed in trays on the seabed at O'Brien Bay-1. Trays were collected after deployment periods of 5 weeks, 56 weeks, 62 weeks, 2 years and 5 years. In addition there was a bioturbation treatment using the burrowing urchin Abatus (at 56 weeks only). Samples were collected from 4 replicate trays of each treatment at each sampling time. Analyses were done of sediment hydrocarbon chemistry, microbial communities, meiofaunal communities, macrofaunal communities and diatom communities. The hydrocarbon treatments were: a synthetic Mobil lubricating oil; the same Mobil lubricating oil after 125? hours use in a vehicle engine; a Fuchs synthetic lubricating oil marketed as highly biodegradable; and Special Antarctic Blend diesel fuel (SAB). A control uncontaminated sediment treatment was used for comparison.

Balance ice velocities for the Antarctic Ice sheet

Balance Ice Velocities for the Antarctic ice sheet.
These ice velocities (in m/yr) represent the (hypothetical) distribution of depth-averaged ice velocities that would keep the Antarctic ice sheet in its present shape (i.e. surface topography and thickness), under the influence of a prescribed accumulation distribution.
The present fluxes were computed using computer code BalanceV2 (by Warner) (outlined in Budd and Warner 1996, and detailed in Fricker, Warner and Allison 2000), using the surface accumulation dataset of Vaughan et al (1999), the ice sheet surface elevation dataset distributed by BEDMAP (attributed to Liu et al 1999), and the ice sheet thickness compilation distributed by the BEDMAP consortium (Lythe et al 2001).
