Short summary
Glaciers preserve records of past climate, but melting is rapidly damaging this information. We examined a new ice core from the Quelccaya Ice Cap in Peru by comparing a variety of chemical markers and using statistical tools. We found that melting has altered the archive mainly where water accumulated and near a fracture, rather than throughout the core. Much of the ice still preserves valuable climate information. Our approach can help assess other threatened glacier records around the world.

Ice cores preserve changes in landscape fires and human-caused combustion. In this study, we compared ice core data from every continent, except Oceania, to computer model simulations of fire. We found a large disagreement in the 1850 CE to 1980 CE black carbon ratio. After exploring changes in emissions, transport, and aerosol microphysical processes as potential reasons for this disagreement, our results suggested that fire emission input datasets for climate models are the primary cause.

This study analyzes how Arctic atmospheric layering affects aerosol distribution by comparing data from the Gruvebadet (61 m) and Zeppelin (472 m) observatories in Svalbard. Results show consistent levels of human-made pollutants like sulfate at both heights, confirming long-range transport from Eurasia. Conversely, natural biogenic tracers were more concentrated at lower altitudes. By integrating chemical and meteorological data, the research highlights the need for multi-level monitoring.

Svalbard is ideal for studying how warming affects snow’s seasonal chemistry. By comparing the snow chemical composition of the 2019–2020 season with 2018–2019 and 2020–2021, we provide an overview of the seasonal and interannual variability of several chemical species on the Svalbard snowpack, furnishing insights into the interplay between short-term meteorological variability and the long-term climatic impacts of climate changes.

A year-long set of submicron aerosol samples (PM1) from Ny-Ålesund, Svalbard, was analyzed by proton nuclear magnetic resonance spectroscopy (H-NMR) and high-resolution time-of-flight aerosol mass spectrometry (HR-TOF-AMS) to characterize the organic fraction. Positive matrix factorization identified five organic aerosol sources. Winter–spring was dominated by Eurasian pollution and summer by marine biogenic aerosols, with occasional wildfire events.

This study represents the primary marine organic aerosol (PMOA) emissions, focusing on their sea–atmosphere transfer. Using the FESOM2.1–REcoM3 model, concentrations of key organic biomolecules were estimated and integrated into the ECHAM6.3–HAM2.3 aerosol–climate model. Results highlight the influence of marine biological activity and surface winds on PMOA emissions, with reasonably good agreement with observations improving aerosol representation in the southern oceans.

We evaluate the impact of the increased snowmelt on the preservation of the oxygen isotope (δ18O) signal in firn records recovered from the top of the Holtedahlfonna ice field located in the Svalbard archipelago. Thanks to a multidisciplinary approach we demonstrate a progressive deterioration of the isotope signal in the firn core. We link the degradation of the δ18O signal to the increased occurrence and intensity of melt events associated with the rapid warming occurring in the archipelago.

We present new data from a 10 m ice core drilled in 2019 and a 8.4 m parallel ice core drilled in 2021 at the summit of Weißseespitze glacier. In a new combination of proxies, we discuss profiles of stable water isotopes, major ion chemistry as well as a full profile of microcharcoal and levoglucosan. We find that the chemical and isotopic signals are preserved, despite the ongoing surface mass loss. This is not be to expected considering what has been found at other glaciers at similar locations.

Measurements of phytoplanktonic dimethylsulfide and its oxidation products in the Antarctic atmosphere allow us to understand the role of the oceanic (sea ice melting, Chl α and dimethylsulfoniopropionate) and atmospheric (wind direction and speed, humidity, solar radiation and transport processes) factors in the biogenic aerosol formation, concentration and characteristic ratio between components in an Antarctic coastal site facing the polynya of the Ross Sea.

In September 2021, the Italian Arctic Research Programme funded a multidisciplinary study along 75° N in the Greenland Sea as part of the CASSANDRA project and the Synoptic Arctic Survey (SAS) programme. This study emphasises the spatial variability of water properties, nutrient distribution, and biological communities determined by oceanographic dynamics in a region influenced by sea ice melting, Atlantic Water inflow, and climatic teleconnections during a record low summer sea ice extent.

The paper presents the first ice-core record of bromine (Br) in the Antarctic plateau. By the observation of the ice core and the application of atmospheric chemical models, we investigate the behaviour of bromine after its deposition into the snowpack, with interest in the effect of UV radiation change connected to the formation of the ozone hole, the role of volcanic deposition, and the possible use of Br to reconstruct past sea ice changes from ice core collect in the inner Antarctic plateau.

Short summary
The study analyzed a year of atmospheric aerosol composition at Col Margherita in the Italian Alps. Over 100 chemical markers were identified, including major ions, organic compounds, and trace elements. It revealed sources of aerosol, highlighted impacts of Saharan dust events, and showed anthropogenic pollution's influence despite the site's remoteness. Enrichment factors emphasized non-natural sources of trace elements. Source apportionment identified four key factors affecting the area.
