Life in Extreme Environments Research #2

The goal of this project was to collect suspended particles and microbes for spectral analysis from deep water around hydrothermal vent study sites on the Juan de Fuca Ridge. To accomplish this, the McLane WTS 6-24-47 Sampler (McLane Research Laboratories, Falmouth, MA) was used. The WTS sampler is a programmable unit which is able to collect individual samples across twenty-four 47mm diameter filters at predetermined intervals and duration. Although only one successful deployment was needed, a maximum of three 3 deployments were possible (deployment opportunities were limited by the number of battery packs available). The initial behavior of the WTS and the ship's schedule both indicated that three deployments would be possible. However, it was revealed upon recovery after the first deployment that the WTS failed as it was preparing to collect its first sample.
