“…However, the average contributions of sea‐salt were calculated to be unexpectedly high at 20%, 39%, and 26% for the Central Yakutia, Zyryanka, and Batagay ice‐wedges, respectively, even though the study area closest to the coast, Batagay, is more than 300 km away. In addition to the distances, Vasil'chuk et al [69] reported that Ca 2+ and HCO 3 − predominate over other ions in the Batagay ice‐wedges, demonstrating the high continentality of this region with little marine influence. Since their Cl − /Na + ratios are also significantly different from that of sea‐salt [69], chloride was not derived exclusively from sea‐salt, as assumed, but instead originated from a range of non‐marine sources, including brine groundwater or continental salts [69–71].…”

Sulfur, with its highly varying stable isotope ratio and involvement in numerous biogeochemical processes, is one of the most widely used elements as an isotopic paleoenvironmental proxy, yet the sulfur isotope ratios of ice‐wedges and their insoluble fraction remain unexplored. This study first presents the sulfur isotopic compositions of soluble sulfate, particulate organic matter (POM), and lithic particles recovered from East Siberian ice‐wedges. Soluble sulfate, primarily representing atmospheric sulfate deposition, shows comparable sulfur isotope ranges in Zyryanka and Batagay, while in Central Yakutia, ice‐wedge sulfate is more enriched in 34S, consistent with the orogenic and cratonic terranes in East Siberia. Given the wedge growth during the inland winter, it is likely that sulfate aerosols were derived mainly from erosion and weathering of regional basement rocks rather than from sea salt spray or biogenic emissions. Within individual ice‐wedges, however, the sulfur isotopic composition of soluble sulfate varies by as much as 7‰, possibly reflecting changes in the relative contributions of sulfur‐isotopically distinct source regions. Beyond the origin of sulfate, greater sulfur isotope fractionations between POM and sulfate during the last glaciation suggest that sulfate may have been anaerobically reduced to sulfide and vice versa in the adjacent root zone.

“…However, multiple considerations are required in the paleoclimate interpretations of individual ice‐wedge geochemical records, and few other studies have reported on the ion content in ice wedges (e.g., 7,23–26 ). Ice wedges are subject to large terrestrial contributions from the ground surface and active layer during the infilling process, with snowmelt potentially washing‐in annually accumulated sea salt from the tundra surface as well as soil‐derived minerals 27 . Further, the origin of impurities in the snowpack must be considered due to regional differences in aerosol formation, transport, and deposition, lithogenic dust inputs, and postdepositional alteration of marine aerosols due to the physical (e.g., sublimation) and chemical (e.g., volatized compounds) evolution of the late‐season snowpack.…”

Ice wedges are a characteristic ground ice feature in permafrost regions that form primarily from the meltwater of the seasonal snowpack. Ice‐wedge oxygen and hydrogen stable isotopes have been used in winter paleotemperature reconstructions; however, until recently, the ion geochemistry of ice wedges has rarely been analyzed as a potential paleoclimate proxy. This potential is greatest for ice wedges located in coastal regions, where marine aerosols are the dominant contributor to snowpack impurities. Here, we evaluate the source and integrity of ionic concentrations of a coastal ice wedge in the northwestern Canadian Arctic (Beaufort Sea coast) to evaluate the use of ice wedges as a marine aerosol archive. Comparison to a regionally comparable snowpack reveals remarkably similar ionic concentrations for Cl−, Na+, Br−, SO42−, Ca2+, and Mg2+, with a Cl−/Na+ ratio similar to bulk seawater (1.80 vs. 1.79 in seawater), suggesting that marine aerosols, probably from sea salt aerosol production during blowing snow events over sea ice as indicated by depleted SO42− values relative to Na+, are probably the dominant contributor to ion concentrations. A previously established linear age model for the ice wedge is used to develop a continuous ion record spanning ~4,600 to ~700 yr b2k. Cl− and Na+ concentrations reveal a strong and continuous increase in concentrations over the late Holocene, thought to be driven by reduced distance‐to‐coast of up to 1 km as a result of coastal erosion. This study presents a novel interpretation of ice‐wedge geochemical data and represents the first Holocene ice‐wedge ion record.
