    Science objectives/activities planned:
The specific objectives of our program are to: (1) determine the post-eruptive distribution of hydrothermal activity and nascent biological assemblages; (2) examine the temporal and spatial changes in benthic communities through in situ observations, sampling, and manipulative experimentation; and (3) correlate of changes in faunal community structure with variations in microbial community composition, in situ fluid chemistry, pH, and temperature. To this end, in situ voltammetric sensor devices (both autonomous and mounted directly on DSV Alvin) will be used to measure a variety of chemical species, including H2S/HS-, FeS, Fe2+, Mn2+, O2, pH and temperature over time in a variety of nascent vent habitats as well as those associated with colonization substrates specifically designed for temporal co-located and integrated comparisons of microbial community structure, fluid chemistry, and macrofaunal colonization. We will deploy a large volume water pump for microbial collection, colonization substrates, in-situ electrochmical sensors, seafloor markers, and OBS arrays. We will recover colonization substrates and OBS arrays. We will sample fauna and rocks, and conduct detailed educational and outreach activities in conjunction with the R2K program.
