2016-2017 USAP Field Season
Quantifying atmospheric iron properties over the Western Antarctic Peninsula
Dr. Yuan Gao
Supporting Stations: Palmer Station
The primary goal of this project is to quantify atmospheric iron properties in the marine atmospheric boundary layer over the Western Antarctic Peninsula (WAP). The specific objectives are to: (1) Identify the sources of atmospheric iron; (2) Determine iron solubility and aerosol composition; (3) Measure the temporal variability of atmospheric iron/dust deposition; and (4) Examine the iron-sulfur relationships. To accomplish these objectives, researchers will collect atmospheric samples, namely aerosol particles and atmospheric deposition, at Palmer Station, using two sampling plans. The first plan is intensive austral summer field atmospheric sampling to be made in two successive field seasons. This will be accomplished using seven air samplers controlled by a wind sector to measure chemical and physical properties of the atmospheric samples. The second plan is for inter-annual measurements of aerosols and atmospheric deposition. This plan will collect total atmospheric deposition monthly and atmospheric aerosols weekly.
Field Season Overview
This will be the second field season for this event, and the general sampling framework used in the first field season will apply. One team member will live and work at Palmer Station from early November to early February. This person will reinstall air samplers plus associated electronic devices such as pumps on the platform behind station, where they will then take air samples.
This event will require support from Palmer Station during the instrument install and uninstall after field work is finished. Support from the electrician and research associate (RA) in regards to the power supply and weather station connection is also needed during the operation of air sampling. There is also a need for assistance with on-site meteorological data for better interpretation of chemistry data.
