Abstract

Sea ice cores were collected at 71.2944˚N, 156.7153˚W and 71.3729˚N, 156.5073˚W in May 2017 and at 71.4730˚N, 156.7294˚W in May 2018. Sea ice cores were drilled with a MARK II ice auger (Kovacs Enterprise). The cores were sectioned immediately after collection with a clean rust-proof, custom alloy bow saw in the field in 5 cm sections and each was collected in sterile Whirlpak® bags. Core sections were melted at room temperature before volumes were allocated for nutrient, water isotope, and bulk...
