Abstract It is widely recognised that the acquisition of high‐resolution palaeoclimate records from southern mid‐latitude sites essential for establishing a coherent picture inter‐hemispheric climate change and better understanding role Antarctic dynamics in global system. New Zealand considered to be sensitive monitor because it one few sizeable landmasses Southern Hemisphere westerly circulation zone, critical transition zone between subtropical influences. has mountainous axial ranges...
Evaluating conflicting theories about the influence of mountains on carbon dioxide cycling and climate requires understanding weathering fluxes from tectonically uplifting landscapes. The lack soil production rate measurements in Earth's most rapidly has made it difficult to determine whether rates increase or decline response rapid erosion. Beryllium-10 concentrations soils western Southern Alps, New Zealand, demonstrate that is produced bedrock more than previously recognized, at up 2.5...
Most of the world’s mountain glaciers have been retreating for more than a century in response to climate change. Glacier retreat is evident on all continents, and rate has accelerated during recent decades. Accurate, spatially explicit information position glacier margins over time useful analyzing patterns measuring reductions surface area. This also essential evaluating how ecosystems are evolving due warming attendant retreat. Here, we present non-comprehensive dataset showing multiple...
Abstract The glacial chronostratigraphy for South Westland established by Almond in 1996 was based on the soil stratigraphy of loess coverbeds landforms and around Saltwater Forest. Loess sheets morphologically identified features were correlated with global climatic events marine oxygen isotope record. Pollen analysis few radiocarbon ages supported chronostratigraphy. In this study, we have used total element, mineral phytolith analysis, luminescence dating to test current correlation...

On hillslopes the balance between soil transport and production determines local thickness age distribution of particles that comprise (where refers to time elapsed since detachment from bedrock). The mean this is defined as residence time, in a landscape with time‐invariant topography (i.e., morphologic steady state), spatial uniformity ensures soils spatially invariant. Thus, given constant soil‐forming factors, variation properties reflects differences driven by nonuniform production....
The northeast-striking, dextral-reverse Alpine fault transitions into the Marlborough Fault System near Inchbonnie in central South Island, New Zealand. slip-rate estimates for are presented following a reassessment of geomorphology and age displaced late Holocene alluvial surfaces Taramakau River at Inchbonnie. Progressive avulsion abandonment floodplain, aided by movements during Holocene, have preserved left-stepping scarp that grows height to northeast. Surveyed dextral (22.5 ± 2 m)...
Liquefaction features and the geologic environment in which they formed were carefully studied at two sites near Lincoln southwest Christchurch.We undertook geomorphic mapping, excavated trenches, obtained hand cores areas with surficial evidence for liquefaction where no was present (Hardwick Marchand).The identified include (1) sand blows (singular aligned along linear fissures), (2) blisters or injections of subhorizontal dikes into topsoil, (3) related to blisters, (4) a collapse...
Abstract Previous attempts to radiocarbon date sediments >10 kyr from the high rainfall region of Westland, New Zealand, a critical location for investigation interhemispheric patterns climate change, have been problematic. This study, building on recent work by Vandergoes and Prior ( 2003 ), shows that AMS 14 C dating pollen concentrates has potential provide more reliable ages than other sediment constituents, including plant macrofossils. The method was applied three sites containing...

Summary The development of terrestrial ecosystems depends greatly on plant mutualists such as mycorrhizal fungi. global retreat glaciers exposes nutrient‐poor substrates in extreme environments and provides a unique opportunity to study early successions fungi by assessing their dynamics drivers. We combined environmental DNA metabarcoding measurements local conditions assess the succession communities during soil 46 glacier forelands around globe, testing whether drivers differ between...
