Project description:We sampled the microbial community at the sea ice edge in McMurdo Sound, Ross Sea at the same location (-77.62S, 165.41E) for four weeks (as described in Wu et al 2019, Nat. Comms.). We had four sampling dates corresponding to weeks 1 to 4: December 28 2014, January 6, 15, and 22 2015. Large volumes of water (150--250 L) were filtered from 1 m depth at the sea ice edge, and passed through three filters sequentially (3.0, 0.8, and 0.1 um, each 293 mm Supor filters). Filters with collected biomass were then placed in tubes with a sucrose-based preservative buffer (20 mM EDTA, 400 mM NaCl, 0.75 M sucrose, 50 mM Tris-HCl, pH 8.0) and stored at -80 C until sample processing. We extracted proteins after buffer exchange into a 3\% SDS solution as previously described Wu et al 2019, Nat. Comms.

Project description:Microbial community of 5 um filtered lake water
Project description:Analysis of bacterial fraction collected on GF/F filters post pre-filtration on 1um filter. 15L were filtered from Bering Strait (BSt) surface water and Chukchi Sea (station 2) bottom waters.
Project description:To clarify the effects of near-infrared radiation, we assessed DNA microarray after water-filtered near-infrared (1100-1800 nm together with a water-filter that excludes wavelengths 1400-1500 nm) irradiation.
Project description:Effluent from geoduck clam larval rearing tanks at two different pH (8.2 and 7.1) was collected at 4 time points (Days 1, 5, 8, and 12) over 12 days in a shellfish hatchery in Washington state, USA. The water was filtered to 0.2 microns to retain the bacterial fraction.
