https://www.pangaea.de/ information publisher tableDigital This dataset presents multiproxy palaeoecological measurements from a 1 m sediment core taken from the deepest point of Purghagoolah (Lake Elusive), a lake of approximately 40 ha and 21 m depth in Croajingolong National Park, Gippsland, southeastern Australia, on Gunaikurnai Country (37°44'50S, 149°27'9E). The core was collected on 9 February 2021 with a Universal Corer (Aquatic Instruments) and subsampled at 0.5 to 1 cm intervals. The record spans approximately the last 1000 years (ca. 844 to 2021 CE). Variables measured include: pollen, reported as raw counts, as percentages of the terrestrial pollen sum, and as pollen accumulation rates, identified by light microscopy; pollen counts for the modelled taxa prepared as input to the REVEALS regional vegetation model; macroscopic charcoal (>125 µm) counts and accumulation rates following hydrogen peroxide digestion; charcoal pyrolysis temperature estimated by Fourier-transform infrared (FTIR) spectroscopy on a Nicolet iN10 MX microscope, accompanied by a modern reference charcoal spectral library; and volume magnetic susceptibility measured on a Bartington ring sensor (75 mm aperture). The age-depth model is based on eleven lead-210 dates (Constant Rate of Supply model) and six accelerator mass spectrometry radiocarbon dates on bulk sediment, with a reservoir correction applied, calibrated with SHCal20 and modelled in rbacon. A regional archaeological radiocarbon compilation (216 ages from 30 sites, obtained from the OCTOPUS v.2.3 / SahulArch database) used to compute a summed probability distribution is also included. Archaeological site coordinates are withheld in accordance with Indigenous Cultural and Intellectual Property (ICIP) principles and Indigenous Data Sovereignty. Data are provided as TAB-delimited tables with full parameter names, units, and event metadata in decimal degrees (WGS84). completed eucalypt forest gippsland Lake Elusive Lake sediment Last millennium Palynology pollen pollen counts Purghagoolah southeastern Australia vegetation history theme <gco:CharacterString>PANGAEA Keyword List</gco:CharacterString> 1995-01-01 creation PANGAEA
