Sheryl BoltonSheryl Bolton
Research Technician
University of Washington

Sheryl is a research technician studying the microbiology of hydrothermal vent fluids. She will be focusing on culturing high temperature anaerobic microorganisms from venting fluids, as well as taking filtered water samples for DNA extraction and microscopic analyses. The University of Washington lab uses a combination of methods to try to understand this complex ecosystem. Sheryl will use hydrothermal fluids and the associated microbes as a window into this mysterious world. By studying the metabolisms (like what they eat) and growth conditions (like temperature and pressure) of these organisms, we can learn about the natural environment in which they live. The lab maintains a large collection of organisms isolated primarily from mid-ocean ridge vents around the world, but few are from systems like the Mariana arc. Plume measurements from the 2003 expedition suggest a wide variety of chemical and environmental selective elements (pH, temperature, energy sources, etc.) that may result in widely different populations of microorganisms.

Bill ChadwickBill Chadwick
CIMRS Program, Oregon State University
NOAA Vents Program, Pacific Marine Environmental Laboratory

Bill Chadwick became very interested in volcanoes when Mount St. Helens erupted during his senior year as a geology major at Colorado College in 1980. St. Helens became the focus of his graduate work at the University of California at Santa Barbara where he earned his PhD. He has worked on active volcanoes ever since, both on land and underwater. His main interest during the 2004 Submarine Ring of Fire expedition is to compare the eruptive behavior of the submarine volcanoes of the Mariana arc to those on land.

Cornel E.J. de RondeCornel E.J. de Ronde
Institute of Geological & Nuclear Sciences (GNS)
Lower Hutt, New Zealand

Cornel de Ronde is a Principal Scientist at the Institute of Geological & Nuclear Sciences. He leads the “Offshore Minerals” part of the “Economic Growth for NZ through Mineral Wealth” program. The offshore minerals research has largely concentrated on seafloor hydrothermal vents associated with submarine arc volcanoes of the Kermadec arc, NE of New Zealand. This group was recently funded $4.9M over the next 6 years to continue their work which started in 1997. Since that time, de Ronde and colleagues at GNS, NOAA and elsewhere, have surveyed 840 km (2/3rds) of the Kermadec arc including 24 major volcanoes and 8 smaller volcanic edifices. They found that 16 of the volcanoes are hydrothermally active, some with several different vent sites. The NZAPLUME III cruise, set for Sept/Oct ’04, will map the remaining part of the arc. De Ronde and colleagues have also participated on research cruises to map the Tofua (Tonga), Tabar-Lihir-Tanga-Feni (Papua New Guinea) arcs and the Ghizo Ridge (Solomon Islands) for submarine hydrothermal venting.

John DowerJohn Dower
Fisheries Oceanographer
University of Victoria, Canada

Dr. Dower's research examines the ways in which biology and physics interact in marine ecosystems and, how these interactions affect the growth and survival of zooplankton and larval fish. For the past 10 years he has also studied the ecology of shallow seamounts, in an attempt to unravel the processes that make these ecosystems such biologically rich environments. During the Ring of Fire expedition Dr. Dower will collect samples of zooplankton and larval fish above each of the seamounts visited, and will participate in the collection of benthic samples and water column video using the ROPOS ROV.

Ben LarsonBen Larson
Graduate Student
University of Washington

Ben Larson is a graduate student in chemical oceanography at the University of Washington in Marvin Lilley's lab. He will be working on shipboard gas chromatographic analysis of volatile concentrations in the sampled fluid. He will determine the amount of dissolved H2, CH4, and N2O in the fluids. The chromatographic data collected at sea is not as detailed as the information that can be obtained from a more advanced land-based apparatus, which can measure the concentrations of a greater number of the dissolved volatile components. However, it is an important component of an exploratory cruise because it yields information about the fluids within a day of their collection. This information is critical in determining where to explore for new hydrothermal venting sites.

Kevin Roe is an Oceanographer at NOAA’s Pacific Marine Environmental Laboratory in Seattle. He is an experienced oceanographer, having first participated in seagoing research over 20 years ago. He has been on numerous cruises that utilize remotely operated vehicles and Alvin. During this cruise, Kevin will be analyzing in near real-time the unique fluids that are venting from the Mariana Arc hydrothermal vents. He will first analyze the vent fluids for dissolved chemicals that are best analyzed immediately, such as ammonia, hydrogen sulfide, and silica, and he will measure pH rapidly before oxidation, precipitation, bacterial utilization or simple degassing occur. Samples will also be preserved for analyzes back onshore. Chemicals that are of interest include dissolved metals such as iron, manganese, zinc, copper, cadmium, silver, and lead and major ions, which include sodium, chloride, magnesium, sulfate, calcium, strontium, potassium, borate, and trace elements. In addition, Kevin will help maintain the Hydrothermal Fluid Particulate Sampler (HTFP), nicknamed "the Beast", and help process the major titanium bottles.
