RV Investigator Voyage IN2016_V01 Seabird Observations

Seabird and incidental cetacean and seal sightings were recorded during daylight hours during the entire voyage. During the voyage, there was 2,581 transect counts of seabirds of 61 species. Coverage was good over the area around Heard and McDonald islands, with some coverage also of Gunnari Ridge. Also covered some deeper parts of the Central Kerguelen Plateau. There were 31 sightings of sea mammals away from the immediate vicinity of Heard and McDonald islands (fur seals were sufficiently common in waters around Heard and McDonald Island to be treated using the same method as for seabirds). Sightings included five species of whales and three species of dolphins. The most intriguing series of sightings comprised seven sightings (approximately eight animals) of blue whales over Gunnari Ridge on 9/10 February (another sighting on 21 January may have been in the same area, as it was approximately 1° north and 1° west of the February sightings)

The data has been published to the Ocean Biodiversity Information System (OBIS https://obis.org).

GBR - Large-scale manta tow surveys of densities of crown of thorns starfish and benthic cover by the AIMS LTMP - Spatial interpolation - 1986 - 2005 (MTSRF 1.1.5, AIMS)

The purpose of this study is to quantify spatial and temporal changes in the density of crown-of-thorns starfish and benthic cover in the Great Barrier Reef. Broad-scale manta tow surveys have been conducted by the Long-Term Monitoring Program (LTMP) of the Australian Institiute of Marine Science since 1986, counting crown-of-thorns-starfish (COTS, Acanthaster planci).

COTS densities fluctuates over years forming southward bound ‘waves’ (the incidence of reefs with new active outbreaks moving south over time, due to the southward transport of larvae by the East Australian Current). Outbreaks in the Swains sector appear to occur independently of the main southward moving wave of COTS outbreaks. The highest overall mean number of COTS per tow was 1.17 in 1988. Active or incipient outbreaks were recorded on 16% and 11% of the reefs surveyed reefs in 2004 and 2005, respectively. The highest percentage of reefs with active outbreaks was 17%, recorded in 1987, 1999 and 2000.

Benthic cover of hard corals, soft corals and dead corals was also estimated on each tow, providing comprehensive estimates of cover around the whole perimeter of reefs.

As part of the Reef Atlas project (now the eAtlas) the manta tow observations were interpolated over the whole GBR by Glenn De'ath using Generalized Additive Models with a Quasibinomial fit. This produced a gridded version of the dataset and is available as a KML and ASCII grid file in WGS84 projection.

2021 State of the Environment Report Marine Chapter – Case Study – Australia's changing reefs

The Marine chapter of the 2021 State of the Environment (SoE) report incorporates multiple expert templates developed from streams of marine data. This metadata record describes the Case Study "Australia's Changing Reefs". 
<strong><em>A PDF of the full Case Study, including figures and tables (where provided) is downloadable in the "On-line Resources" section of this record as "CASE STUDY 2021 – Australia's Changing Reefs"</em></strong>



DESCRIPTION OF THE FOCUS OF THE CASE STUDY
Shallow temperate and tropical reefs around Australia, including their macroalgal and coral habitats, fishes and mobile invertebrates. A nationally standardised dataset is used to provide a quantitative metric-based analysis of state and trends in these components across the continent, rather than presenting a review of location-specific knowledge.

PRESSURES/ISSUES OF IMPORTANCE
Changes in the ocean climate have been widespread on shallow reefs since the last SoE report (2016), including three major tropical heatwaves responsible for widespread coral bleaching (2016, 2017 and 2020), and increasing annual maximum sea temperatures along much of the Australian coastline [1].

DATA STREAM(S) USED IN CASE STUDY
All trends are calculated from compatible underwater visual census data from the Reef Life Survey (RLS; https://reeflifesurvey.com/), Australian Temperate Reef Collaboration (ATRC; https://atrc.org.au/) and the Australian Institute of Marine Science (AIMS; https://www.aims.gov.au/docs/research/monitoring/reef/reef-monitoring.html) Long Term Monitoring program. All RLS and ATRC data used are available through the National Reef Monitoring Network database through IMOS. Only data collected between the years 2008-2020 (inclusive) were used, with spatial coverage as shown in plots. Indicator calculation is provided in reference 5, and at https://reeflifesurvey.com/indicators/. 
A number of other monitoring programs exist around Australia, albeit not all with directly compatible and/or open access data with which to calculate the indicators used for this case study. As such, trends reported are those from analysis of this national standardised dataset and the knowledge of the authors, and should not be taken to reflect a synopsis of all published research and results of other monitoring programs.

NERP TE Project 8.2 - Do no-take marine reserves contribute to biodiversity and fishery sustainability? Assessing the effects of management zoning on inshore reefs of the Great Barrier Reef Marine Park , 2011-2014 (JCU)

This project is providing a direct assessment of the ecological effects of multiple-use zoning on inshore reefs of the GBRMP. Underwater visual census (UVC) monitoring of fish and benthic communities is being carried out at 50 no-take marine reserve (green zone) sites and at 50 sites that have remained open to fishing within the Palm, Magnetic, Whitsunday and Keppel Island groups. Long-term monitoring surveys are providing information on:
<ol>
<li>

The effects of no-take marine reserves on populations of both species that are fished and other non-fished species. 
</li>
<li>

Variations in structure of fish communities due to the reserves and natural disturbances.
</li>
<li>

Structure and dynamics of marine species on the sea bed.
</li>
<li>

Coral health, bleaching, incidence and severity of coral disease and coral predators.
</li>
<li>

Temporal monitoring of the relative number of fishing lines recorded at each site will be used to assess the distribution of fishing effort and provide information on the levels of non-compliance with zoning regulations.

NESP MaC Project 3.6 - Improving data on the distribution and ecological value of temperate subtidal seagrass in tayaritja (Furneaux Group of Islands), Tasmania

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2023 project "Improving data on the distribution and ecological value of temperate subtidal seagrass in tayaritja (Furneaux Group of Islands), Tasmania". For specific data outputs from this project, please see child records associated with this metadata.

Seagrass meadows are a dominant marine ecosystem of tayaritja  (Furneaux group of Islands) in the north-eastern waters off Tasmania, with historical coarse mapping indicating extensive beds of Posidonia, Amphibolis, Hetreozostera and Zostera seagrass. The beds of Posidonia and Amphibiolis are potentially some of the largest and deepest extents found in temperate waters of Australia. Lack of data on the distribution and ecological value of these seagrass habitats represents a significant knowledge gap in understanding Australian wetland natural assets that provide a range of ecological, social, cultural and economic values. This project aims to map the extent and ecological composition, population structure and blue carbon value of the seagrass beds around tayaritja in partnership with the Tasmanian Aboriginal Centre. This project will help managers and the Aboriginal communities to understand the significance of these seagrass meadows and understand how they may be monitored.

Outputs
• Seagrass extent and composition map for Furneaux group [dataset]
• Video and imagery of seagrass [dataset]
• Final project report [written]

Water quality guidelines for the Great Barrier Reef, 1990 - 2005 (MTSRF, AIMS)

The purpose of this study was threefold: (1) to identify water quality guideline values based on existing ecological data; (2) to identify areas where guidelines are met or exceeded, and (3) to quantify the likely ecological changes associated with improving water quality to meet the guidelines.

Water quality guideline values were derived based on two separate approaches. Firstly, long-term average water quality conditions were characterized for the six NRM regions within the GBR. Cape York, a region with little land use, was used as a Reference Condition Site, after controlling for latitudinal gradients along the shelf. Cape York has the lowest concentrations in the coastal zone but similar water quality to the other regions in the offshore zone. Second, the GBR water quality data were related to the spatial distribution of macroalgae, and the richness of hard corals and octocorals. Substantial increases of macroalgal cover and declines in the biodiversity of hard corals and octocorals were found with increasing turbidity and chlorophyll.

These two approaches were used to identify the following trigger values: mean annual values below 10 m Secchi disc depth, and mean annual concentrations exceeding 0.45 microgram / litre chlorophyll, 2.0 mg / litre suspended solids, &gt;1.5 micromol / litre particulate nitrogen, and 0.09 micromol / litre particulate phosphorus.

The models display the regions within the GBR where the guideline values are exceeded. The models also show that up to 60% reductions in macroalgal cover and similar increases in coral biodiversity on inshore reefs are likely if the proposed trigger values were met (all other factors being equal).The study confirms that chlorophyll and water clarity, macroalgal cover and hard coral and octocoral diversity are useful as water quality indicators for monitoring inshore reef status.

Data Units:
- Water quality: Secchi disk depth: m; water column chlorophyll concentration: microgram / litre;
- Macroalgal cover: percent; coral richness: species per reef; octocoral richness: taxa per reef.
