* = a stainless steel coupler was used to join two packages and join packages to the sinker bar. † = temperature probes were purchased from Onset (O) and Antares (A). Probes are located 53 cm from the top of the OsmoSampler packages. ‡ = Spectra lengths are given in measured units and expected lengths based on stretch within the hole (in parentheses); some downhole depths for Spectra are not given because additional line was used to ensure that the plugs could seat at the correct depths. Lifting loops were weaved at 10.5, 23, and 35.5 m for the 43.4 m long rope; 14.3, 26.8, 39.3, 51.8, and 64.3 m for the 66.2 m long rope; and 2, 14.5, and 27.5 for the 39.5 m long rope. FLOCS = Flow-through Osmo Colonization System. MBIO = microbiology, OS = OsmoSampler, BOSS = BioOsmoSampling System.
