The quality is evaluated using porosity-depth data from IODP Site U1459 and the industry well Houtman-1 in the northern Perth Basin, offshore southwestern Australia. The compaction trend is estimated with improved accuracy using linear and exponential trending equations. Compaction trend estimation and decompaction process are crucial for analyzing numerical basin evolution (e.g., subsidence) and evaluating hydrocarbon reservoirs and geological storages. This study introduces BasinVis 2.0 and demonstrates its functions through extensive case studies comprising of well data from the Perth Basin (Australia) and the Vienna Basin (Austria).

These improved functions are implemented in BasinVis, upgrading the software to Version 2.0. Based on these studies and user feedbacks, we have improved the workflow, revised user interfaces and developed novel techniques for the compaction trend estimation of infilling sediments and its applications (decompaction process) to sedimentary basin reconstruction and visualization. High long-term CO 2 caused warm climates and high sea levels, with sea-level variability dominated by periodic Milankovitch cycles.īasinVis 1.0, a MATLAB-based modular open-source program released in 2016, has been used for multiple application studies of sedimentary basin analysis and modelling in both academic and industry fields. The largest GMSL fall (27 to 20 ka ~130 m) was followed by a >40 mm/yr rise (19 to 10 ka), a slowing (10 to 2 ka), and a stillstand until ~1900 CE, when rates began to rise. Continental-scale ice sheets (“Icehouse”) began ~34 Ma (>50 m changes), permanent East Antarctic ice sheets at 12.8 Ma, and bipolar glaciation at 2.5 Ma. Peak warmth, elevated GMSL, high CO 2, and ice-free “Hothouse” conditions (56 to 48 Ma) were followed by “Cool Greenhouse” (48 to 34 Ma) ice sheets (10 to 30 m changes).

These GMSL estimates are statistically similar to “backstripped” estimates from continental margins accounting for compaction, loading, and thermal subsidence. Using Pacific benthic foraminiferal δ ¹⁸ O and Mg/Ca records, we derive a Cenozoic (66 Ma) global mean sea level (GMSL) estimate that records evolution from an ice-free Early Eocene to Quaternary bipolar ice sheets. We conclude that AIS sensitivity to climate and ocean forcing has been substantially amplified by long-term landscape evolution.

Glacial erosion is primarily responsible for enhanced ice sheet retreat via the development of increasingly low-lying and reverse sloping beds over time, particularly within near-coastal subglacial basins. We use a numerical ice sheet model to subject the AIS to schematic climate and ocean warming experiments and find that bed topographic evolution causes a doubling in ice volume loss and equivalent global sea level rise.

Here we investigate the evolving sensitivity of the AIS using a series of data-constrained reconstructions of Antarctic paleotopography since glacial inception at the Eocene-Oligocene transition. However, the effect of the progressive temporal evolution of Antarctica's subglacial landscape on the sensitivity of the Antarctic Ice Sheet (AIS) to climatic and oceanic change has yet to be fully quantified. Ice sheet behavior is strongly influenced by the bed topography.
