Historical winter sea-ice concentration data estimates utilising a diatom proxy for marine sediment core SO136-111

The purpose of this study was to re-evaluate the paleo sea-ice record for marine sediment core SO136-111. We applied a generalized additive model, and compared the estimates from GAM with those estimates derived from weighted averaging partial least squares, the Imbrie and Kipp Transfer function and the Modern Analogue Technique.
We provide the first record of paleo winter sea-ice concentration data for core SO136-111, based on a diatom proxy. Core SO136-111 provides a record for winter sea-ice concentrations over the last 220 kyr BP.
Gravity core SO136-111 (56°40'S, 160°14'E, water depth 3912 m) was retrieved from the Emerald Basin, in the East Indian sector of the Southern Ocean south of the modern Antarctic Polar Front. The core was retrieved in 1998 during the TASQWA cruise on board the FS SONNE.

Biodeposition from four bivalves species using natural estuary water in Australia

The threatened status of shellfish reefs has been well established globally (e.g Beck et al 2011) however the ecological consequences of these losses is still largely unknown. In Australia, shellfish reefs are one of the most imperilled marine habitat types (Gillies et al 2018), due to historical overharvest and widespread eutrophication of coastal waters through the use of fertilizers, livestock and human waste. 
Marine bivalves are important ecosystem engineers providing habitat, shelter and a food source  for other species in benthic soft-sediment environments. In addition, filter-feeding bivalves link benthic and pelagic components of ecosystems through filtration and excretion. Through their filter feeding, they produce large amounts of faeces (digested seston) and pseudofaeces (rejected particles bound up in mucus) which are deposited on the benthos. This process brings energy and nutrients from the pelagic system to the benthic system (bentho-pelagic coupling). 
The removal of large quantities of seston can serve an important ecosystem function by improving water quality and clarity. The filtration of water performed by bivalves has been demonstrated to reduce water turbidity, improving light penetration and thereby enhancing growing conditions for seagrasses (Wall et al 2008). In systems where healthy populations of bivalves remain, they can filter a volume equivalent or larger than the entire estuary volume within the residence time of the water (zu Ermgassen et al 2013). While such densities of oysters are rare today, this highlights the critical ecosystem services that are lost when oyster reefs decline. Furthermore, it demonstrates the potential functions that can be regained through oyster reef restoration. 
Given the increasing awareness of the decline of these ecosystems, interest in restoration efforts to restore critical ecosystem functions has been growing. However, conservation and restoration decision making is underpinned by reliable quantification of relevant ecosystem services (zu Ermgassen et al 2016). For example, there are plans to restore some of the natural oyster reefs of Sydney Rock Oyster (Saccostrea glomerata) in Port Stephens, New South Wales. One of the main drivers motivating this restoration project is restoring lost ecosystem services. 
The filtration rates of Australian oysters has been demonstrated in aquarium studies using filtered water augmented with algae, yet little is known about filtration and biodeposition rates of oysters using raw seawater. In this study, we provide the first evaluation of the filtration and biodeposition rate of four species of bivalves using raw seawater, providing a proxy for natural biodeposition rates. As such, this study provides a first indication of the filtration/nutrient cycling function that may be restored following oyster restoration efforts.

Resource Assessment Frameworks

As part of the process of implementing the good governance aspects of ESD within the Department it is essential to ensure that the resource assessments completed by the Department are being done in an appropriate and consistent manner. This process can be assisted by the development and use of a suitable resource assessment framework for each unit/team to follow. Such a framework should outline what needs to be examined, why it needs to be examined and, most importantly, how it has been examined in the past and how it will be examined in the future.
At least four separate (but related) assessment frameworks will be needed to cover the types of issues the Department will need to report against in the coming years. These four frameworks will cover:
* Individual species assessments
* Broader ecosystem impacts of individual fisheries (bycatch and habitat impacts)
* Regional Impacts
* Social and economic impacts

Competition between subspecies of the mangrove Ceriops tagal along a salinity gradient in north Queensland

The distribution of seedlings of the two subspecies of Ceriops tagal (Ceriops tagal var. tagal and Ceriops tagal var. australis) was measured in relation to soil pore water salinity in the "Wet Desert" in Missionary Bay on Hinchinbrook Island and at Chunda Bay. At each location, three 60 m transects, spaced 10 m apart, running from the interface between the terrestrial and mangrove forests into the mangroves were established. Three replicate soil cores were taken at 10 m intervals along each transect and the salinity of pore water draining into each hole was measured using a conductivity meter. If water did not percolate into the hole, soil samples were taken to the laboratory and squeezed under low pressure to obtain a pore water sample. The density of seedlings of both subspecies was also measured in 3 replicate 10 m² quadrats at each 10m interval along each transect.Freshly picked, mature hypocotyls were weighed and planted out in trays in a shadehouse in different combinations of salinity and proportion of each subspecies. The salinities used were 0, 15, 30, 45 and 60 ppt, while the proportions of subspecies were 100% of a given subspecies, 67% tagal-33% australis and 33% tagal-67% australis. Stem height, percent mortality and percent leaf emergence were measured every week for six weeks and every 2 weeks for a further 4 months.
 This research was undertaken to determine if competition between the two subspecies of Ceriops tagal contributed to the difference in the distribution of the two subspecies along a salinity gradient.

SAIMOS - Biological and Flow Cytometry data collected from CTD stations in South Australia, in November 2019

Flow cytometry data was collected in November 2019, in waters off South Australia. 
The general purpose of the study is to be able to establish background knowledge on the ecosystem on the continental shelf of South Australia and the impact of upwelling/saline outflow events on microbial communities to ultimately develop a biogeochemical model of the region. Sampling was carried out during cruises conducted on board the RV Ngerin as part of the Southern Australian Integrated Marine System (SAIMOS). During each cruise, the physical, chemical and biological properties of the chlorophyll fluorescence maximum (DCM) layer were investigated. Flow cytometry data has been collected for picophytoplankton, bacteria and viruses.
Six main stations have been sampled over the course of the study, five are located on the 100 m isobath, i.e. RS (35.508S, 136.278E), B2 (35.418S, 136.148E), B3 (35.258S, 136.048E), SAM2CP/B4 (35.168S, 135.418E) and SAM5CB/B5 (35.008S, 135.198E), and one from an offshore station (B1; 36.188S, 136.178E) located southwest of Kangaroo Island. Note that combining the distances between stations (14–25 nautical miles), the average component of the current velocity at middepth along the shelf (0.01 m s21) and the average speed of the vessel (i.e. 9 knots) indicate that different water masses were sampled at each station. Additional samples have on occasion been collected from the National Reference Station (NRS) at Kangaroo Island (35.832S, 136.447E) and the SA Spencer Gulf Mouth Mooring (SAM8SG, 35.25S, 136.690E), where the saline outflow occurs. Since July 2019, sampling has also been conducted at "Gulf" sites: Upper Spencer Gulf (USG) and Gulf St Vincent (GSV), with the original sites identified as "Shelf" sites.

Corals and coral communities of Lord Howe Island, Australia

Ecological and taxonomic surveys of hermatypic scleractinian corals were carried out at approximately 100 sites around Lord Howe Island. Sixty-six of these sites were located on reefs in the lagoon, which extends for two-thirds of the length of the island on the western side. Each survey site consisted of a section of reef surface, which appeared to be topographically and faunistically homogeneous. The dimensions of the sites surveyed were generally of the order of 20m by 20m. Where possible, sites were arranged contiguously along a band up the reef slope and across the flat. The cover of each species was graded on a five-point scale of percentage relative cover. Other site attributes recorded were depth (minimum and maximum corrected to datum), slope (estimated), substrate type, total estimated cover of soft coral and algae (macroscopic and encrusting coralline). Coral data from the lagoon and its reef (66 sites) were used to define a small number of site groups which characterize most of this area.Throughout the survey, corals of taxonomic interest or difficulty were collected, and an extensive photographic record was made to augment survey data. A collection of the full range of form of all coral species was made during the survey and an identified reference series was deposited in the Australian Museum.In addition, less detailed descriptive data pertaining to coral communities and topography were recorded on 12 reconnaissance transects, the authors recording changes seen while being towed behind a boat.
 The purpose of this study was to describe the corals of Lord Howe Island (the southernmost Indo-Pacific reef) at species and community level using methods that would allow differentiation of community types and allow comparisons with coral communities in other geographic locations.

Age vs. Depth of core BAR 9403 (located off the coast of Sumatra). Age has been calculated through modelling based on oxygen isotope records

The age with depth of core BAR9403 is calculated through 18O values, which are then correlated with the SPECMAP age-model. Based upon these measurements the age at the deepest part of the core (275cm) was calculated to be ~33,200yrs BP. The age vs. depth profile indicates a reasonably constant sedimentation rate, with an average deposition rate of ~8cm/1000yrs.

IMOS - National Mooring Network - Acidification Moorings (AM) Sub-Facility

The Acidification Moorings sub-facility is responsible for building an ocean carbon and acidification monitoring network for Australian waters.  These moorings provide key observations to help us understand and address the problem of increasing ocean acidification.  
Each mooring is equipped with surface CO2 systems, using proven and robust technology.  Three sensors will determine surface CO2, temperature and salinity.  The hydrochemistry sampling at the National Reference Stations will also provide total alkalinity data, as will future pH sensors on the moorings, allowing for a complete determination of the carbonate system and pH. 
Acidification moorings are co-located at three National Reference Stations:
* the Yongala NRS in Queensland (replaced in September 2013 after Tropical Cyclone Yasi) (instrumentation: Battelle Seaology pCO2 monitor, Aanderaa Oxygen Optode and a WETLabs WQM)
* the Maria Island NRS in Tasmania (instrumentation: Battelle Seaology pCO2 monitor, Aanderaa Oxygen Optode and Sea-bird Electronics, model SBE16plus V2 SEACAT), and
* the Kangaroo Island NRS in South Australia (removed in June 2013, and redeployed in May 2014) (instrumentation: Battelle Seaology pCO2 monitor, Aanderaa Oxygen Optode and Sea-bird Electronics, model SBE16plus V2 SEACAT).  
A fourth acidification mooring is located adjacent to the Heron Island reef slope in the Wistari channel on the Great Barrier Reef (instrumentation: Battelle Seaology pCO2 monitor, Aanderaa Oxygen Optode and Sea-bird Electronics, model SBE16plus V2 SEACAT).  
The Yongala, Wistari and Maria Island acidification moorings are located to characterise changes down the east coast of Australia and the influence of the East Australian Current on CO2 uptake and acidification from the Great Barrier Reef to the Southern Ocean.  The Kangaroo Island mooring monitors the deeper waters upwelled on the South Australian shelf which are expected to have higher CO2 and thus could accelerate the exposure of ecosystems to acidification earlier than in other regions.
