“…For SIM (figure 4c), highest percentages are visible in the surface layers associated with the recent seasonal decrease in sea-ice extent (approx. stations [67][68][69][70][71][72][73][74][75][76][77][78][79][80][81][82][83][84][85]. This reaches a maximum of 1.8% at station 84, equivalent to 0.8 m of sea-ice derived freshwater in an 85 m thick Surface Water (neutral density γ n < 27.55) layer.…”

“…For MET, the salinity endmember was set to 0, whilst for sea-ice a salinity of 5 [68] and a δ 18 O of +1.8 (taken as representative of surface waters in this region adjusted for the fractionation that occurs during freezing [69]) were used. Estimates of 'PO' were formulated from mean phosphate and oxygen measurements taken from Antarctic snow (for the meteoric endmember [70][71][72][73][74] and sea-ice [74][75][76][77][78]). The δ 18 O endmember for MET carries the greatest uncertainty, as it must represent a combination of both local (seasonally varying) precipitation and glacial melt, which can encompass a large variability in δ 18 O signal depending on the exact latitude and elevation at which the precipitation accumulated.…”

“…Brine samples from sea ice were obtained using the sack hole method (e.g., Gleitz et al, 1995). A 0.5 m depth hole was drilled below the ice surface using an ice corer, and then covered with a 5 cm-thick urethane lid to reduce heat and gas transfer across the brine/atmosphere interface.…”

“…Brines were sampled using the sack-hole sampling technique at 20 and 40 cm below the ice surface (Gleitz et al, 1995). Each sack hole was covered with a plastic lid to prevent snow and ice shavings from falling into the pit (Thomas et al, 2010).…”
