The data file summarizes field observations of ice properties and constituents. All field observations of ice properties, snow, ice algae and under ice water in this study were conducted on landfast, first-year sea ice located within 10 km of Point Barrow, Alaska (71.38°, 156.48°) on the near-shore Beaufort and Chukchi Sea shelf (< 3 km from shore). Samples were collected May - early June 2011-2012 at a water depth of approximately 6-8 m. The stations selected were free of rubble and pressure ridges, decreasing the chance of contaminating debris from the shore and/or re-suspended sediment. During 2011, field work was conducted from May 3 to May 26. Stations were selected and sampled from a range of overlying snow depths (0 - 42 cm). The snow depth at each station was measured with a meter stick and snow depth was consistent (± 2 cm) within a radius of approximately 2 m. In 2012, four stations were sampled from May 15 to June 4 every 3 – 7 days. Stations were selected according to the initial snow depths. Station 1 started with 5 cm, Station 2 with 1.5 cm, Station 3 with 21 cm, and Station 4 with 30 cm.
