1.00,"acoustic samples","acoustic measurements to characterize underwater noise, in-air noise, and ice vibrations"
2.00,"chemistry samples","chemistry mearurements were performed on surface sediment, suspended sediment, sea water, ice core, bivalve mollusc, and benthic amphipod samples collected from the study area.  Depending on matrix type, one or more of the following chemical analyses were performed on these samples:  grain size, total organic carbon (TOC), trace metals, carbon-13, total suspended solids, saturated hydrocarbons (SHC), polynuclear aromatic hydrocarbons (PAH), and geochemical biomarkers (steranes/triterpanes [S/T])"
3.00,"water chemistry samples","water chemistry measurements were performed at various depths within the water column for temperature, salinity, conductivity, turbidity, current velocity, and current direction"
