Restoration of coastal wetlands has the potential to deliver both climate change mitigation, called blue carbon, and adaptation benefits communities, as well supporting biodiversity providing additional ecosystem services. Valuing carbon sequestration may incentivize restoration projects; however, it requires development rigorous methods for quantifying sequestered during wetland restoration. We describe a accounting model (BlueCAM) used within Tidal Blue Carbon Ecosystems Methodology...
Aquaculture is a critical food source for the world's growing population, producing 52% of aquatic animal products consumed. Marine aquaculture (mariculture) generates 37.5% this production and 97% seaweed harvest. Mariculture may offer climate-friendly, high-protein source, because they often have lower greenhouse gas (GHG) emission footprints than do equivalent farmed on land. However, sustainable intensification low-emissions mariculture key to maintaining low GHG footprint as scales up...
Mangroves provide many ecosystem services including a considerable capacity to sequester and store large amounts of carbon, both in the sediment above-ground biomass. Assessment mangrove carbon stock relies on accurate measurement tree biomass, which traditionally involves collecting direct measurements from trees relating these biomass using allometric relationships. We investigated potential predict derived unmanned aerial vehicle (UAV), or drone, imagery. This approach has dramatically...
Tidal marshes store large amounts of organic carbon in their soils. Field data quantifying soil (SOC) stocks provide an important resource for researchers, natural managers, and policy-makers working towards the protection, restoration, valuation these ecosystems. We collated a global dataset tidal marsh (MarSOC) from 99 studies that includes location, depth, site name, dry bulk density, SOC, and/or matter (SOM). The MarSOC 17,454 points 2,329 unique locations, 29 countries. generated...
Using combined miniature archival light and salt-water immersion loggers, we characterise the year-round individual at-sea movements of Europe's only critically endangered seabird, Balearic shearwater Puffinus mauretanicus, for first time. Focusing on non-breeding period, show that all 26 breeding birds tracked from their site Mallorca in Mediterranean Sea successfully made a 2-4 month migration into Atlantic Ocean, where they utilised well-defined core areas off Portuguese French coasts. As...
Abstract The soil in terrestrial and coastal blue carbon ecosystems is an important sink. National inventories require accurate assessments of these to aid conservation, preservation, nature-based climate change mitigation strategies. Here we harmonise measurements from Australia’s apply multi-scale machine learning derive spatially explicit estimates stocks the environmental drivers variation. We find that vegetation are primary variation at continental scale, while ecosystem type, terrain,...

Spatial patterns in the number of species, individual animals and community composition benthos Hawkesbury Estuary, N.S.W., are described related to physicochemical factors. Replicate grabs were taken from deep shallow sites located on transects across estuary for each five times at intervals 3 months. The species individuals always differed significantly along but pattern difference varied with both depth time. Although a monotonic decline never occurred, two most- seaward usually supported...
The coastal Runnelstone Reef, off southwest Cornwall (UK), is characterised by complex topography and strong tidal flows a known high-density site for harbour porpoise (Phocoena phocoena); European protected species. Using multidisciplinary dataset including: sightings from multi-year land-based survey, Acoustic Doppler Current Profiling (ADCP), vertical profiling of water properties high-resolution bathymetry; we investigate how interactions between flow drive the fine-scale spatio-temporal...
Marine ecosystem restoration is fast becoming the primary tool for repairing socio-ecological functions and economic benefits of coastal ecosystems. Healthy seascapes are characterized by many interacting species intermingled habitats (e.g., seagrass, kelp, shellfish, sedimentary) that co-create ecological substantial socio-economic value. These co-created not only build stability resilience at seascape scales, but synergistically combine to enhance productivity greater than sum individual...
Understanding the spatial distribution of human impacts on marine environments is necessary for maintaining healthy ecosystems and supporting 'blue economies'. Realistic assessments impact must consider cumulative multiple, coincident threats differing vulnerabilities to these threats. Expert knowledge often used assess in because empirical data are lacking; however, this introduces uncertainty into results. As part a assessment Spencer Gulf, South Australia, we asked experts estimate score...
Unprecedented changes to the marine environment and growth of bio-logging science make detailed study movement ecology threatened species timely. Here, we spatial temporal patterns space use by a critically endangered seabird: Balearic shearwater Puffinus mauretanicus. Using suite systems, 67 foraging trips were recorded during incubation periods between 2011 2014 from one species' largest colonies (Sa Cella, Mallorca). Most birds followed narrow flight corridors restricted neritic grounds...
A combination of scientific, economic, technological and policy drivers is behind a recent upsurge in the use marine autonomous systems (and accompanying miniaturized sensors) for environmental mapping monitoring. Increased spatial–temporal resolution coverage data, at reduced cost, particularly vital effective spatial management highly dynamic heterogeneous shelf environments. This proof-of-concept study involves integration novel sensors onto buoyancy-driven submarine gliders, order to...
Despite their great socio-economic importance, sandy beaches have attracted little ecological research. This is unfortunate since, contrary to popular belief, they support diverse assemblages whose species are mostly small and buried which deserve protection as part of ecologically sustainable development (ESD). Moreover, the management linked adjacent ecosystems becoming increasingly important because vulnerability burgeoning human pressures including climate change. Although there large...

Abstract Blue carbon ecosystems sequester and store a larger mass of organic per unit area than many other vegetated ecosystems, with most being stored in the soil. Understanding fine-scale drivers variability blue soil stocks is important for supporting accurate accounting effective management saltmarsh mangrove habitats abatement. Here, we investigate influence local- regional-scale environmental factors on using case study from South Australia. We sampled 74 cores mangrove, intertidal...
Assessing the impacts of multiple, often synergistic, stressors on population dynamics long-lived species is becoming increasingly important due to recent and future global change. Tiliqua rugosa (sleepy lizard) a skink (>30 years) that adapted survive in semi-arid environments with varying levels parasite exposure highly seasonal food availability. We used an exhaustive database 30 years capture-mark-recapture records quantify both environmental conditions lizard's survival rates long-term...
Seagrass, saltmarsh and mangrove habitats are declining around the world as anthropogenic activity climate change intensify. To be able to effectively restore maintain healthy coastal-vegetation communities, we must understand how why they have changed in past. Identifying shifts vegetation environmental or human drivers of these, can inform successful management restoration strategies. Unfortunately, long-term data (i.e. decades hundreds years) on coastal vegetated ecosystems that discern...
