Kevin Roe

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 Lost City Hydrothermal chimneys. 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.
