Temperate Highland Peat Swamps on Sandstone (THPSS) are a form of topogenous mire found the plateau areas eastern Australia. They well recognised for their ecological value, but our understanding geomorphic structure, function and evolution remains limited. Across 19 sites, valley fills THPSS comprise sequences mineral-rich sand loam deposits. Basal gravel sediments have low organic content carbon to nitrogen (C:N) ratios (a measure peat formation) dated between 15.3 9 kyr cal. BP, with...
A unique index-record of Last Interglacial (Marine Isotope Stage 5e MIS5e) relative sea level (RSL) and wave climate history in South-east Australia is presented from Robbins Island, western Bass Strait. This applied to interpret the wider MIS5e coastal evidence around At combination low wind energy, a tide-modified regime sand supply resulted shoreline progradation throughout MIS5e. preserved time-series paleo-sea across 7 km wide strandplain (Remarkable Banks). After highstand, RSL...
Abstract Palaeochannels of lowland rivers provide a means investigating the sensitivity river response to climate-driven hydrologic change. About 80 palaeochannels lower Macquarie River southeastern Australia record evolution this distributive fluvial system. Six were dated by single-grain optically stimulated luminescence. The largest (Quombothoo, median age 54 ka) was on average 284 m wide, 12 times wider than modern (24 m) and with 21 greater meander wavelength. Palaeo-discharge then...
Abstract Rivers with discontinuous watercourses are part of the spectrum river diversity. Chain‐of‐ponds types contain irregularly spaced, steep‐sided ponds that separated by preferential flow paths on swampy valley fill. They often endangered ecological communities and receiving greater attention for conservation restoration. Very little is known about how these form, they have evolved function. Here we present Late‐Quaternary evolution one last remaining large‐scale chain‐of‐ponds systems...
