Samples were collected at 2 cm resolution from a 2 m snow pit in January 2024 during the TNB-2324 campaign. They were analysed for water isotopes ratios using high resolution laser absorption (Liquid Water Isotope Analyser, Los Gatos Research, DLT-100) and anion and cation concentrations using ion chromatography (Dionex, Integrion HPIC System). Here we report water isotopes of oxygen (δ18O) and hydrogen (δD), and concentrations of fluoride, methanesulfonic acid, chloride, bromide, nitrate, sulfate, acetate, formate, oxalate, sodium, ammonium, potassium, magnesium and calcium. The snow pit covers the period 2014-2024 and was dated using annual layer counting. Summers were identified where δD peaks aligned with peaks or shoulders of methanesulfonic acid and non sea salt sulfate. Winters were determined where a δD trough aligned with a peak in chloride and sodium concentrations. The snow pit data will help understand aerosol transport and deposition processes to the Upper Priestly Glacier site and interpret longer climate proxy records from ice cores at the site. 161.574297 161.574297 -74.0202 -74.0202 161.574297 -74.0202 2024-01-09T00:00:00 2024-01-09T00:00:00 2100.0 2100.0 vertical profile Royal Society Te Apārangi https://doi.org/10.13039/501100001509 MFP-VUW2107 How Did Changing Sea Ice Conditions Impact Primary Production In The Ross Sea Over The Past 200 Years?
