Holocene glacier fluctuations

Quaternary Science Reviews, 2015
A global overview of glacier advances and retreats (grouped by regions and by millennia) for the Holocene is compiled from previous studies. The reconstructions of glacier fluctuations are based on 1) mapping and dating moraines defined by ¹⁴C, TCN, OSL, lichenometry and tree rings (discontinuous records/time series), and 2) sediments from proglacial ...

HOLOCENE ENVIRONMENTAL CHANGE IN SOUTH-EAST ALTAI EVIDENCED BY SOIL RECORD

Geography, Environment, Sustainability, 2019
The soils of Russian Altai highlands were used as a paleoenvironmental archive, as a source of dating material, and as a chronostratigraphic marker to describe Holocene environmental change in the studied area. Based on calibration intervals of 14C dates

SEA LEVEL AND PALAEOCLIMATIC CHANGES IN THE SOUTH AND MIDDLE CASPIAN SEA REGION SINCE THE LATEGLACIAL FROM PALYNOLOGICAL ANALYSES OF MARINE SEDIMENT CORES

Geography, Environment, Sustainability, 2010
A review of pollen, spores, non-pollen palynomorphs and dinocyst analyses made in the last two decades is proposed here. Building on spare palynological analyses before 1990, a series of new projects have allowed taking cores in the deeper parts of the ...

Paleo sea-level indicators and proxies from Greenland in the GAPSLIP database and comparison with modelled sea level from the PaleoMIST ice-sheet reconstruction

GEUS Bulletin, 2023
One of the most common ways to assess ice-sheet reconstructions of the past is to evaluate how they impact changes in sea level through glacial isostatic adjustment. PaleoMIST 1.0, a preliminary reconstruction of topography and ice sheets during the past

Late Holocene tectonic land-level changes and tsunamis at Mitla lagoon, Guerrero, Mexico [PDF]

Geofísica Internacional, 2009
Sedimentological, stratigraphic and geochemical data record abrupt land elevation change, coastal subsidence, and changes in the salinity of Mitla lagoon that may be associated with a tsunami around 3400-3500 yr BP.

THE EVOLUTION OF CLIMATE AND LANDSCAPES OF THE LOWER VOLGA REGION DURING THE HOLOCENE

Geography, Environment, Sustainability, 2010
The results of the palynological analysis and 14C dating of the most complete sequences of the Holocene sediments were used for a detailed reconstruction of multi-cyclic alternations of climate phases and zonal and intrazonal plant formations that were ...

Holocene Relative Sea-Level Changes Along the Southern Coast of Bodrum Peninsula, SW Anatolia

Coğrafi Bilimler Dergisi, 2023
Bodrum Peninsula, which developed under the influence of the extensional tectonic regime in the west of the Anatolian plate, is one of the areas where indicators reflecting relative sea-level changes are seen above the present sea level. These indicators

A Quality Improvement Initiative to Standardize Pneumocystis jirovecii Pneumonia Prophylaxis in Pediatric Patients With Solid Tumors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric patients with extracranial solid tumors (ST) receiving chemotherapy are at an increased risk for Pneumocystis jirovecii pneumonia (PJP). However, evidence guiding prophylaxis practices in this population is limited. A PJP‐related fatality at our institution highlighted inconsistent prescribing approaches and concerns about

Reconstruction of mean January air temperature of Holocene in the lower Kolyma River region

Лëд и снег, 2022
The object of study is ice wedges at 10 sites in the lower Kolyma River. The Holocene age of ice wedges is determined on the basis of radiocarbon dating of the enclosing sediments and location of ice wedges in alases, floodplains and lacustrine-paludal ...

Sickle Cell Disease Is an Inherent Risk for Asthma in a Sibling Comparison Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Sickle cell disease (SCD) and asthma share a complex relationship. Although estimates vary, asthma prevalence in children with SCD is believed to be comparable to or higher than the general population. Determining whether SCD confers an increased risk for asthma remains challenging due to overlapping symptoms and the ...
