Full description

Cryoconite holes were sampled in the Bunger Hills as part of the Biodiversity of East Antarctica: Underwater and Terrestrial (BEAUT) field program in 2024/2025. Cryoconite holes were located on the Edisto/Apfel glacier, proximal to Edgeworth David field camp. For each cryoconite hole, a series of samples were collected including water (for chemistry, n = 16) and sediment (for physical parameters, invertebrate eDNA and extraction, n = 20).
    
Approximately 10 to 100 g of sediment was collected into a 50 mL sterile falcon tube, depending on the amount of sediment layer available. All equipment including the ice axe and red glove were sterilized using 10% bleach and ethanol between each hole. Basic measurements of each hole were also recorded including water depth, hole height, and width. Samples were frozen at -20 for transport and then moved into -80 storage at the AAD. Additionally, several “background” soil samples were taken from the nearby moraine island approx. 500 m away from cryoconite sampling locations to understand any influence or similarities between nearby soil communities.

This data set is water chemistry results and physical measurements of a range of cryoconite holes on the Edisto/Apfel Glaciers, Bunger Hills, East Antarctica. Water samples were sent to ALS for analysis of the following parameters: electrical conductivity, bicarbonate, carbonate, total alkalinity, sulfate, chloride, calcium, magnesium, potassium, sodium, ammonia, nitrite, nitrate, total N, TP, reactive phosphorus, ionic balance, total anions, total cations, TOC.

Cryoconite is a powdery, windblown dust composed of rock particles, soot, and microbes that accumulates on glaciers and ice caps. Due to its dark colour, it absorbs solar heat and melts into the ice, forming cylindrical, water-filled "cryoconite holes" that harbor vibrant micro-ecosystems.
