Frontiers | The Recent Relationships Between Andean Ice-Core Dust Record and Madeira River Suspended Sediments on the Wet Season

Dust particle studies in ice cores from the tropical Andes provide important information about climate dynamics. We investigated dust concentrations from a 22.7 m ice-core recovered from the Quelccaya Ice Cap (QIC) in 2018, representing 14 years of snow accumulation. The dust seasonality signal was still preserved with homogenization of the record due to surface melting and percolation. Using a microparticle counter, we measured the dust concentration from 2–60 μm and divided the annual dust concentration into three distinct groups: fine particle percentage (FPP, 2−10 μm), coarse particle percentage (CPP, 10−20 μm), and giant particle percentage (GPP, 20−60 μm). Increased dust was associated with the warm stage of the Pacific Decadal Oscillation index (PDO) after 2013 with significant increases in FPP and a relative decrease in CPP and GPP. There was a positive correlation between PDO and FPP (r = 0.70, p-value < 0.005). CPP and GPP were dominant during the mainly PDO co ....

Frontiers | An Assessment of Glacier Inventories for the Third Pole Region

Glacier inventory is the basic data for hydrological, water resources and climate change research. Glacier inventories have been created for the Third Pole Region (TPR) or high Asia, yet they are different in coverage area and vary largely in quality. It is thus necessary to assess their quality in order to provide information for potential users to choose the right glacier inventories. Using the analytic hierarchy process, this study selects eight assessment factors and assesses the comprehensive quality of eight glacier inventories of the TPR by grading. The assessment results indicate that the comprehensive quality of the small-scale glacier inventories of WHGI, KPGI, PGI-2 and SETPGI is generally higher than that of the large-scale ones of RGI, GGI18, CGI-2 and HKHGI. Of the latter, the quality-ranking order from high to low is CGI-2, GGI18, RGI and HKHGI. However, the comprehensive quality of CGI-2 and GGI18 is comparable over the CGI-2 area. The comprehensive quality of CGI-2, GG ....

The Message from the Glaciers

It was not so long ago that the parts of the globe covered permanently with ice and snow, the Arctic, Antarctic, and Greater Himalayas (“the abode of the snows” in Sanskrit), were viewed as distant, frigid climes of little consequence. Only the most intrepid adventurers were drawn to such desolate regions as the Tibetan Plateau, which, when finally surveyed, proved to have the ....
