The Indo-Pacific Warm Pool (IPWP) is the largest source of atmospheric heating and moisture on Earth, energizing global energy budgets controlling ocean-atmosphere circulation. However, mechanisms driving orbital-scale changes in hydroclimate proxy records precipitation isotopic composition remain poorly known. Here, we use isotope-enabled Transient Climate Evolution (iTRACE) experiment to inve...

Abstract The history of sea level across the Quaternary is essential for assessing past and future climate. Global sea-level reconstructions are typically derived from oxygen isotope curves, but require calibration with geological constraints that scarce prior to last glacial cycle (>130 thousand years ago). Here we show coral reef terrace sequence at Huon Peninsula (Papua New Guinea) provid...

Stable isotopes (Deuterium and Oxygen-18) have a broad application in many of water related sciences. Precipitation is the most important input to the water cycle which shows considrable spatial and temporal variability in its isotope content. To study the precipitation isotope content, 51 samples from August 2015 to July 2016 have been collected mainly on a monthly basis with few events based ...

it is very important to determine the stable nitrogen isotope ratio for the nitrogenous substances in aerosols and the geochemistry behavior of stable nitrate ion isotopes in aerosols in order to elucidate the chemical and physical functions of clouds. hence, aerosol field sampling was conducted in the skies offshore from malibu beach and santa barbara, california, u.s.a. on 16 and 18 july 200...

the relationship between qt dispersion and myocardial ischemia is still controversial. therefore, we aimed to investigate the relationship between qtd and the severity and extent of myocardial ischemia. in this cross-sectional study, 141 patients having symptoms of cad who referred to our medical center during 2009-2010, and were examined with myocardial isotope scan and ecg, were enrolled. bas...

stable isotope analysis, being used in many research areas, has also been applied in archaeology during the last three decades to address questions regarding the paleoclimatology and ancient diet, mobility and migration. despite the growing number of the application of stable isotope analysis in archaeological studies, there is a very few research in this regard in archaeology of iran. this res...
