Another aspect of the science on Mt Erebus is the analysis of the gas plume. Jean Wardell, graduate student at New Mexico Tech, is working on her PhD in Geochemistry and is here to set up acid traps along the crater rim for analysis of trace minerals from the gas plume. Specifically she is looking for the metals such as magnesium, lead, arsenic, and selenium.
The system she is using is simple and easy to transport and the hope is her results will be similar to the pump system of Jessie Crain who has set up her project next to Jeanís. The pump system requires a gas generator, pumps and hoses, is heavy to haul and not reasonable to set up on volcanoes that are dangerous to get close to. Jeanís traps are set up and can be left out for several days, then collected and analyzed. If the data correlates with the pump system then Jeanís procedure can be used in the future for volcano study.
