| Zusammenfassung |
| A buoy based instrument platform (the "O-buoy") was designed, constructed,
and field tested for year-round measurement of ozone, bromine monoxide,
carbon dioxide, and meteorological variables over Arctic sea ice. The O-buoy
operated in an autonomous manner with daily, bi-directional data
transmissions using Iridium satellite communication. The O-buoy was equipped
with three power sources: primary lithium-ion battery packs, rechargeable
lead acid packs, and solar panels that recharge the lead acid packs, and can
fully power the O-buoy during summer operation. This system was designed to
operate under the harsh conditions present in the Arctic, with minimal
direct human interaction, to aid in our understanding of the atmospheric
chemistry that occurs in this remote region of the world. The current design
requires approximately yearly maintenance limited by the lifetime of the
primary power supply. The O-buoy system was field tested in Elson Lagoon,
Barrow, Alaska from February to May 2009, and deployed in the Beaufort Sea
in October 2009. Here, we describe the design and present preliminary data. |
