Abstract Under the influence of recent global warming, modulation frequencies and amplitude El Niño-Southern Oscillation (ENSO) its impacts on climate have become great concerns to community. Antarctic is sensitive these changes owing tropical Southern Hemispheric (SH) teleconnections. surface air temperature (SAT) reconstructed approximately for past five centuries (~1533 1993 CE) based multiple oxygen isotope (δ 18 O) records ice cores from East West Antarctica show dominant oscillations...
Abstract Antarctic sea ice is a critical component of the ocean‐climate system. Sea concentration (SIC) records various oceanic sectors Antarctica available since 1979 reveal dramatic changes in recent years; however, there no consensus yet on drivers variability, and their future projections. The lack long‐term SIC has impeded quantification trends forcing factors mechanisms. Here, we present record (1809−1993 CE) for Western Indian Ocean Sector (WIOS) derived from new core oxygen isotope...
El Niño Southern Oscillation (ENSO), Interdecadal Pacific Oscillations (IPO), and their phase relation with the Annular Mode (SAM) largely control Antarctic climate variability. The relative roles of these modes remain elusive, particularly in backdrop global warming. In this study, we present a seasonally resolved new ice core (IND33) record oxygen isotope (δ 18 O) for past two centuries (1809–2013 CE) from coastal Dronning Maud Land (DML) to investigate role temperature variability trend....
Purpose of the study: This research is focused on examining impact Covid-19 societal social cohesion. Furthermore, role Muslim communities in tackling challenges has also been investigated detail.
 Methodology: The discussed conducted by detailed analysis related literature. paper thus based upon secondary data gathered from different sources including newspapers, articles published journals, books, and reports diverse non-governmental, governmental organizations.
 Main Findings:...
Stable isotopes of Antarcticice cores are used extensively in reconstructing the past climate. Variations snow accumulation patterns and post-depositional processes such as changes isotope ratios due to diffusion may complicate these records. We analyzed spatio-temporal variations accumulation, stable isotopic composition, factors controlling their distribution along two transects Dronning Maud Land (DML) Princess Elizabeth (PEL) regions East Antarctica. The δ 18 O δD dominantly influenced...
Abstract. We have analysed the spatial variations in mean stable water isotopic values, snow accumulation patterns and moisture sources along coast to inland transects central Dronning Maud Land (cDML) Princess Elizabeth (PEL) regions of East Antarctica. The δD δ18O varied systematically from coastal cDML PEL response surface air temperature. While elevation effect was not clearly visible, isotope appeared be associated with region temperature region, which ultimately are elevation. Further,...
