“…Marine cores from the continental shelf of northeastern Queensland suggest mangroves flourished during the marine transgression 14,000 years ago (Grindrod et al, 1999;Grindrod et al, 2002;Moss and Kershaw, 2000). Mangrove distribution peaked around 9,000 years ago, indicating the relatively flat continental shelf was inundated and protected by the redevelopment of the outer Great Barrier Reef (Grindrod et al, 1999;Grindrod et al, 2002). A recent study from King River in the Kimberley region found Rhizophora forests were established prior to 9,000 cal.…”

“…A mid-Holocene highstand between 1-2m higher than present mean sea level (pmsl) inundated low lying coastal regions and mangrove communities expanded. As sea-level stabilised mangroves flourished during a 'Big Swamp' phase, with the rapid vertical accretion of mangrove muds evident in sedimentary archives throughout northern Australia and the Torres Strait (Crowley, 1996;Grindrod et al, 1999;Grindrod and Rhodes, 1984;Rowe, 2007aRowe, , 2007bWoodroffe et al, 1989;Woodroffe et al, 1985). Falling sea levels in the late Holocene caused prograding coastlines associated with the contraction of mangrove communities and succession to freshwater swamps (Crowley et al, 1990;Crowley and Gagan, 1995;Luly et al, 2006;Proske et al, 2014b;Rowe, 2007aRowe, , 2007b.…”

A wealth of palaeoecological studies from the Australasian region identify periods of significant environmental change during the Holocene. However, relatively few studies have focused on the coastal lowlands of tropical northern Australia, limiting our ability to accurately reconstruct this vast bioregion's history. This study addresses the gap in spatially distributed paleoenvironmental research in northern Australia by producing the first reconstructions from the South Wellesley This research examined seven sediment profiles using micro X-ray fluorescence geochemical data and particle size analysis.

“…However, a closer match of the GBR record of coral δ 13 C values with simulations is possible by some adjustments in the chosen parameter values, for example, by assuming that land carbon density was with 60 kgC/m 2 on the shelf platform twice as high as on the slope (best-guess scenarios shown in Figure 3b). This is in line with the substantially warmer conditions (Brenner et al, 2020;Felis et al, 2014a;Figure S5 in Supporting Information S1) and developing mangrove forests (Grindrod et al, 1999) after 13.0 ka in the GBR, and with estimates of combined tree, dead wood and soil carbon density of mangrove forests today (Donato et al, 2011;Sanderman et al, 2018). Furthermore, some fine-scale adjustments in the simulated coral δ 13 C are obtained, when the variability of atmospheric δ 13 CO 2 is also taken into account (scenario "111-best-prescribed" in Figure 3b).…”

The δ 13 C values of atmospheric carbon dioxide (CO 2 ) reconstructed from ice cores show that during the last deglaciation CO 2 with lower amounts of 13 C was released to the atmosphere in two rapid episodes (Bauska et al., 2016;Schmitt et al., 2012). In parallel to the onset of the deglacial CO 2 rise (Figure 1b) a prominent drop in the atmospheric δ 13 CO 2 values (Figure 1c) leading to a minimum centered at ∼16.0 ka is most commonly attributed to upwelling of old 13 C-depleted waters in the Southern Ocean (Köhler et al., 2005a;Menviel et al., 2018;Schmitt et al., 2012). However, the cause of a second prominent minimum in atmospheric δ 13 CO 2 centered at ∼12.4 ka during the Northern Hemisphere's Younger Dryas cold period (Figures 1a and 1c) that is synchronous to another period of CO 2 rise is not well understood (Bauska et al., 2016;Schmitt et al., 2012). Multi-proxy evidence invoke another pulse of Southern Ocean upwelling to explain these late deglacial carbon cycle changes (Anderson

Redating the earliest evidence of the mid-Holocene relative sea-level highstand in Australia and implications for global sea-level rise

Reconstructing past sea levels can help constrain uncertainties surrounding the rate of change, magnitude, and impacts of the projected increase through the 21 st century. Of significance is the mid-Holocene relative sea-level highstand in tectonically stable and remote ( far-field) locations from major ice sheets. The east coast of Australia provides an excellent arena in which to investigate changes in relative sea level during the Holocene. Considerable debate surrounds both the peak level and timing of the east coast highstand. The southeast Australian site of Bulli Beach provides the earliest evidence for the establishment of a highstand in the Southern Hemisphere, although questions have been raised about the pretreatment and type of material that was radiocarbon dated for the development of the regional sea-level curve. Here we undertake a detailed morpho- and chronostratigraphic study at Bulli Beach to better constrain the timing of the Holocene highstand in eastern Australia. In contrast to wood and charcoal samples that may provide anomalously old ages, probably due to inbuilt age, we find that short-lived terrestrial plant macrofossils provide a robust chronological framework. Bayesian modelling of the ages provide improved dating of the earliest evidence for a highstand at 6,880±50 cal BP, approximately a millennium later than previously reported. Our results from Bulli now closely align with other sea-level reconstructions along the east coast of Australia, and provide evidence for a synchronous relative sea-level highstand that extends from the Gulf of Carpentaria to Tasmania. Our refined age appears to be coincident with major ice mass loss from Northern Hemisphere and Antarctic ice sheets, supporting previous studies that suggest these may have played a role in the relative sea-level highstand. Further work is now needed to investigate the environmental impacts of regional sea levels, and refine the timing of the subsequent sea-level fall in the Holocene and its influence on coastal evolution.
