Geophysical Research LettersHigh‐resolution records from past interglacial climates help constrain future responses to global warming, yet are rare. Here, we produce seasonally resolved climate records from subarctic‐Canada using micron‐scale measurements of oxygen isotopes (δ18O ...

Field trip guide to Oligocene Limestones and Caves in the Waitomo District [PDF]
, 2013 The field guide runs from Hamilton to Waitomo to Te Anga and return in limestone-dominated country developed in transgressive sedimentary deposits of the Oligocene Te Kuiti Group – a world class example of a temperate shelf carbonate depositional system.

Evaporite-karst processes, landforms, and environmental problems [PDF]
, 2008 Evaporite karst is widespread, but relatively unknown when compared with carbonate karst; this special issue addresses that lack of familiarity. Evaporite rocks have much higher solubilities and faster dissolution rates than carbonate rocks and they also

Speleothem and biofilm formation in a granite/dolerite cave, Northern Sweden
International Journal of Speleology, 2014 Tjuv-Antes grotta (Tjuv-Ante's Cave) located in northern Sweden is a round-abraded sea cave ('tunnel cave'), about 30 m in length, formed by rock-water abrasion in a dolerite dyke in granite gneiss. Abundant speleothems are restricted to the inner, mafic

Speleothems as proxy for the carbon isotope composition of atmospheric CO2 [PDF]
, 1993 We have measured the stable isotope ratios of carbon in a suite of recent cave deposits (\u3c200 \u3eyears) from the San Saba County, Texas, USA. The methodology for dating these deposits using excess 210Pb was recently established [Baskaran and Iliffe ...

Verification of the causes of glaciations and sea level changes using the records of calcite speleothems. [PDF]
International Journal of Speleology, 2000 The luminescence of calcite speleothems displays an exponential dependence on soil temperature unless there is a dense cover of forest over the cave to dampen it.

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Understanding the mechanisms linking low‐latitude monsoon variability and high‐latitude ice‐sheet discharge is critical for elucidating past atmospheric teleconnections, yet direct evidence for such linkages during the last glacial period remains limited. Here we present a high‐resolution terrigenous input record from the South China Sea (SCS)

Sulphate concentration in cave dripwater and speleothems:long-term trends and overview of its significance as proxy for environmental processes and climate changes [PDF]
, 2015 Sulphate concentrations in speleothems identify major volcanic eruptions, provide useful information on soil and aquifer dynamics and, in similar fashion to the 14C bomb peak, its Anthropocene peak can be used to date recent cave formations. However, the

Holocene Climate Changes: Unraveling Processes, Mechanisms, and Impacts Across Spatiotemporal Scales
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract As the most recent interglacial period and the timeframe for the development of human civilization, the Holocene provides a critical perspective for understanding future climate under continued global warming. This special collection focuses on Holocene climate changes and features 14 interdisciplinary studies.

Dating and Interpretation of Secondary Carbonate Deposits from the Last Interglacial [PDF]
, 2004 The age of secondary carbonate deposits has been determined via U/Th dating. According to the investigation of speleothems from the high Alpine Spannagel Cave (Zillertal Alps, Austria), a first warming occurred 135,000 years (135 kyr) ago.
