Summary: This study identified three organic compounds as suitable quantitative markers for TRWPs through non-target screening and liquid-chromatography high-resolution mass spectrometry identification. These compounds showed a linear response in standard addition experiments and were correlated with TRWP contents in environmental samples, suggesting their potential as markers for TRWP quantification. The use of organic markers would allow for easy quantification of TRWPs with traditional tandem MS equipment in organic trace analytical laboratories, facilitating data generation on TRWP occurrence in various environmental matrices.

Summary: The decline of sea ice in the North Atlantic and Nordic Seas during the last glacial period, known as Dansgaard-Oeschger (D-O) events, contributed to repeated abrupt atmospheric warmings recorded in Greenland ice cores. By analyzing records from the NEEM ice core and sediment cores, researchers discovered that the replacement of stable multiyear sea ice with seasonal sea ice amplified the abrupt climate warming during D-O events, highlighting the importance of feedbacks associated with seasonal sea ice expansion in driving the North Atlantic ocean-climate system.

Summary: Impurities in polar ice, especially cloudy bands with high impurity concentrations, play a critical role in ice flow, deformation, and the integrity of the ice core record. In this study, we used a combination of advanced techniques to analyze cloudy bands in glacial ice from the East Greenland Ice-core Project (EGRIP) ice core. We classified the cloudy bands into seven different types and determined the mineralogy and localization of micro-inclusions. Our results showed that the majority of minerals found are related to terrestrial dust, with quartz, feldspar, mica, and hematite being the most common. We also found carbonaceous particles, dolomite, gypsum, and rare minerals such as rutile, anatase, epidote, titanite, and grossular. The 2D impurity imaging revealed the spatial distribution of impurities in the cloudy bands, with grain boundaries containing Na, Mg, and Sr, and the grain interior containing dust-related analytes like Al, Fe, and Ti.

Summary: Based on a 210-year bromine record, this study finds that the bromine signal in ice at Dome C in East Antarctica is preserved and not influenced by variations in ultraviolet radiation. However, due to limited satellite measurements and low sea-ice variability in the past 30 years, the effectiveness of bromine enrichment as a proxy for past sea-ice reconstructions at Dome C is still uncertain.
