NESP TWQ Project 5.3 - Benthic light as ecologically-validated GBR-wide indicator for water quality: Drivers, thresholds and cumulative risks, 2019-2020 (AIMS)

The project is developed a water quality indicator based on benthic PAR (light penetrating to the seafloor). The project experimentally estimated irradiance thresholds for ecosystem health for the Great Barrier Reef and developed a new remote sensing algorithm to estimate and map benthic irradiance throughout the GBR. This fed into Reef Plan report cards, RIMReP monitoring, and assessments of drivers of cumulative risks. The project extension focused on: work with stakeholders to embed the products into their workflows; improved the remote sensing algorithm with seasonal and regional cloud corrections; and evaluated an additional benthic light product based on the eReefs models to complement the remote sensing product.

AIMS Cross-Shelf Series Photo Transects - Pandora, Rib, John Brewer, Myrmidon Reefs Coral Communities from 1980 to 2005

Starting in the early 1980s, thirty-two permanent photographed sites were established by AIMS to learn about the dynamic behavior of coral communities in the full variety of reef-zones from sheltered nearshore reefs in turbid waters through to the slopes and surf zones of outer reefs, each of which has its own distinctive assemblage of corals.  With allied field studies, it was established that in the last two decades of the 20th Century, GBR coral communities exhibited substantial resilience (in terms of restoration of prior percent cover and composition) following disturbances such as floods, crown-of-thorns starfish and cyclone-generated waves. There is presently little basis for setting resilience targets for coral reefs, especially in relation to the great variety of environmental settings and reef-types within the Great Barrier Reef.  This project will help scientists provide a much stronger evidence base for the setting of targets and evaluating contemporaneous changes compared to more benign years of late last century.
A number of AIMS ecological studies in the 1980s focused on this series of reefs, distributed across the continental near AIMS headquarters, Townsville. 
There are three to six photo-transects per reef, and each photographed up to 19 years between 1980 and 2005.  Access to the sites was extremely weather and tide dependent, which accounts for differences among the sites in their frequency of visitation.
For illustrated examples of this series, see Introduction to the AIMS Cross Shelf Series, available from the links below.
Pandora Reef is a &amp;#39;turbid coastal reef&amp;#39; in waters that often gets stirred up and made muddy by south-east winds.

Rib and John Brewer are &amp;#39;mid-shelf&amp;#39; reefs where the water is rarely turbid.

Myrmidon Reef (an &amp;#39;outer-shelf reef&amp;#39;) sits way out in clear waters, pounded by massive waves from the Coral Sea.

In Done (1982), seventeen coral community types were distinguished and named after characteristic dominant species. The communities displayed patterns of distribution at two spatial scales - a between reef scale and a within reef scale (i.e. the zonation of communities into characteristic areas on individual reefs. The patterns were distinctive, despite the considerable overlaps in the species composition of the communities defined.   However, some subsets of the seventeen communities may represent stages in a succession which takes place over a time scale of decades to centuries. The photo-transects described here were established to investigate this proposition in this area with a history of severe and aperiodic natural disturbances (viz. cyclones, Acanthaster outbreaks, and coral bleaching).

Rapid Ecological Assessment (REA) of coral biodiversity and reef health in Manus and New Ireland Provinces, northern Bismarck Sea, Papua New Guinea

Fringing reefs at 19 locations in the Tigak Islands and 17 locations around Manus Island in the northern Bismarck Sea, Papua New Guinea were surveyed in August/September 2006. Locations were selected to provide the broadest range of reef habitat types. At each location, two sites were surveyed (deep: &gt;10m and shallow: An inventory of species, genera and families of sessile benthic taxa was compiled for each site. The inventory included hard corals, soft corals, zoanthids, sponges, macro-algae and other sessile macro-benthos. At the end of each survey, the inventory was reviewed and each taxon was categorized in terms of its relative abundance in the community. For each hard coral taxon present, a visual estimate of the total amount of injury (dead surface area) present on colonies at each site was made in increments of 0.1, where 0 = no injury and 1 = all colonies dead. In addition, for each taxon, the proportion of colonies in each of three size classes (up to 10cm, 10 to 50cm and greater than 50cm colony diameter) was recorded. When identification of hard coral species was not possible, notes and photographs were taken and, if necessary, small samples were collected for later examination. Most specimens were lodged with the local TNC Office for use as a reference collection. Some coral samples were taken to Australia to compare with reference collections in the Museum of Tropical Queensland and the Australian Institute of Marine Science.At the end of each survey, site attributes were recorded based on an assessment integrated over the length of the survey. Attributes included percentage cover of major benthic groups and substrate types, biogenic reef development, exposure to wave energy, depth range, angle of the reef slope, visibility (m) and the presence of any unique or outstanding biological features or evidence of impacts.
 1. To conduct a survey of species diversity by identifying hard and soft corals and other benthic marine organisms and by compiling a detailed list of species for each site and for the survey region in general2. To assess coral community types, their current status and health, and the extent of impacts on these reefs from disturbances such as coral bleaching, crown-of-thorns starfish outbreaks, destructive fishing practices, and terrestrial runoff
 The method used was similar to that employed during biodiversity assessments for TNC and other agencies in other parts of the Indo-West Pacific, Indonesia and Australia and provides the opportunity for future comparisons of species diversity, composition and community structure of these different areas in terms of their coral communities.

SAIMOS - Biological and Flow Cytometry data collected from CTD stations in South Australia, in February 2008

Flow cytometry data was collected in February 2008, 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 (FM) 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), B4 (35.168S, 135.418E) and 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.

National Environmental Research Program - Seafloor map of the Flinders Commonwealth MPA

A comprehensive and detailed multibeam sonar-based map of the shelf-break region of the Central Flinders Commonwealth Marine Reserve (CMR).  It illustrates the extent that several canyon-head incisions are present in this region, and that inset from the shelf-break is a relatively extensive area of cross-shelf reef. Some of the canyon-head incisions are characterised by exposed reef areas, and these are indicated by localised regions of rapid change in depth. The cross-shelf reef is generally very low profile, but characterised by distinct reef ledges where bedding planes in the sedimentary rock types have eroded. These ledges, often between 1-2 m in height, can run for several kilometres as distinct features. The method of data extraction is based on Lucieer (2013). Three are three classes of seafloor map- one from GEOBIA, one from digitisation and one from Probability of Hardness based on Angular Profile Correction.

Distribution and abundance of juvenile starfish in the central Great Barrier Reef

The densities of juvenile Acanthaster planci (Crown-of thorns starfish) were sampled at 16 inner mid-shelf reefs of the central Great Barrier Reef during trips in July, September and November 1986 and were resurveyed in November/December 1987. The reefs sampled were: Lodestone, Keeper, Little Broadhurst, Bowden, Mid, Stanley (3 independent surveys), Old, Charity, Hope, Showers, Bait, Ross, Square, Robertson, Credlin and Bushy-Redbill.A destructive sampling technique was chosen due to the small size and cryptic behaviour of the starfish during their first 10-12 months of benthic development. On each reef two replicate 10x1m transects were sampled at each of two arbitrarily chosen sites located within three depth zones (reef base, reef crest and reef flat) and two exposure categories (windward and leeward). Surface features of each transect were mapped with a resolution of 15cm. Loose and detachable pieces of substrate were removed, broken into small pieces and searched underwater for the presence of stafish. While the study was primarily focused on Acanthaster planci, all starfish species were recorded. The position of each starfish encountered was recorded on the substratum map and the specimen retained for subsequent identification and measurement. Sampling of a transect ceased either when it reached bed rock or a depth of 30cm.In order to determine the precision of the sampling method, the reef with the highest densities observed on the first cruise in 1986 (Stanley Reef) was resurveyed twice more during subsequent cruises that year.In both 1986 and 1987, transects at one leeward site on each of four reefs were sampled nocturnally. Twelve 12 transects were marked out and 6 were sampled in the usual way during the day and 6 were searched without destruction after 2100 hours.
 This research was undertaken to:1. define the juvenile habitat of Acanthaster planci and 2. investigate the spatial and temporal abundance of juveniles and their contribution to the population outbreaks observed in this species.

Australian Baseline Sea Level Monitoring Project: Cape Ferguson Station

The National Tidal Centre maintains a SEAFRAME (SEA-Level Fine Resolution Acoustic Measuring Equipment) station at Cape Ferguson as part of an array of fourteen standard stations, and two supplementary stations (Lorne and Stony Point), which are owned by port operators. The equipment provides accurate measurements of sea level as well as recording meteorological parameters (water temperature, air temperature, barometric pressure, wind direction, wind gust and wind speed). These data are available online.
 These stations were deployed for the Australian Baseline Sea Level Monitoring Project. The project is designed to monitor sea level around the coastline of Australia. The ultimate goal is to identify long period sea level changes, with particular emphasis on the enhanced greenhouse effect on sea level.

Satellite Remote Sensing - Satellite Contributed Ocean Colour - SeaWIFS Chlorophyll Concentration in the Southern Ocean: Weekly, Johnson et al 2013

The Aqua and Orbview satellites carry a MODIS and SeaWIFS sensors (respectively) that observes sunlight reflected from within the ocean surface layer at multiple wavelengths. These multi-spectral measurements are used to infer the concentration of chlorophyll-a (Chl-a), most typically due to phytoplankton, present in the water. 
There are multiple retrieval algorithms for estimating Chl-a and aggregating the data over time. This data set is a reprocessed copy of 9km monthly and 8-day versions produced globally by NASA, adjusted for the Southern Ocean south of latitude 30S. The full methodology is described in Johnson, R., Strutton, P.G., Wright, S.W., McMinn, A., Meiners, K.M., 2013. Three improved satellite chlorophyll algorithms for the Southern Ocean. Journal of Geophysical Research: Oceans. doi: 10.1002/jgrc.20270. It is expected that the data set will be periodically updated with contemporary data as it becomes available.
There are four sub-streams within this data set. A monthly and an 8-day series for MODIS/Aqua and similarly for SeaWIFS. Note that SeaWIFS ceased operation in late 2010 so there will be no further SeaWIFS data. 
The data represented by this record is weekly data for SeaWIFS.

NESP MB Project E1 - Guidelines for analysis of cumulative impacts and risks to the Great Barrier Reef

This record provides an overview of the scope of NESP Marine Biodiversity Hub Project E1 - "Guidelines for analysis of cumulative impacts and risks to the Great Barrier Reef". No raw data products are anticipated for this project.

The project will develop guidance for the analysis of cumulative impacts and risks to the environmental, social and economic values of the GBR. The project will use existing information to develop guidance for use by GBRMPA, DoEE, the Queensland Government and proponents of future development proposals. The project will build on the work undertaken in the GBR Strategic Assessment and support works undertaken under the Reef 2050 plan. The guidance will provide a practical science-based approach to assessment of cumulative risks to the Reef. Research will focus on providing a general and repeatable approach to be applied at the whole-of-reef scale (to meet planning, assessment and reporting requirements of the GBRMPA) and also at the development-site-scale (to meet the environmental assessment requirements of the GBRMPA and future proponents). The guidance will be developed in close collaboration with the GBRMPA and DoEE to ensure it is practical and compatible with relevant legislation and policy applicable to proposed actions within the GBR. The project will include a case study focused on attributing impacts of pressures and their cumulative impacts on shallow-water coral reefs of eastern Australia (including cumulative impacts for the whole-of-GBR). It will also examine how this could be applied to shallow temperate reefs follow recent risk assessments conducted in NSW. Research is primarily designed to meet the specific needs of GBRMPA and future proponents. NSW DPI, QLD Government and Parks Australia, may also benefit from the case study and insights to assessment of cumulative impacts. 
Planned Outputs
• Case Study Report on GBR &amp; Coral Sea reefs pressure analysis.
• Final report - guidance for analysis of cumulative impacts and risk

Phytoplankton dynamics in a seasonal estuary - Swan River Estuary, Western Australia

To examine how phytoplankton biomass and species' successions are influenced by multiple variables in the Swan River estuary, the four primary phytoplankton groups were modelled with a three-dimensional hydrodynamic model (Estuarine and Lake Computer Model; ELCOM) coupled with an ecological model (Computational Aquatic Ecosystem Dynamics Model; CAEDYM) to simulate physical and ecological processes in the Swan River estuary, Western Australia.  The model was run using inputs of bathymetry, meteorological, flow and water quality data.  The water quality data was collected weekly at nine sites along a 20 km domain of the Swan River estuary, from Blackwall Reach to Success Hill Reserve from October 1994 to July 1998 for this study.
