Science Summary:
The main goal of this work is to provide the first reliable record of pre-industrial carbon monoxide (CO) concentration and stable isotope composition in the Arctic atmosphere, which will also be representative of a large part of the Northern Hemisphere. Carbon monoxide concentrations are a crucial component of any complete modern or past atmospheric data set because CO plays a key role in global atmospheric chemistry by being the largest single sink of hydroxyl radicals in the lower atmosphere. Carbon monoxide concentration in combination with stable isotopes is also a powerful tracer for large-scale biomass burning variations. Pre-industrial carbon monoxide concentration in the northern hemisphere (where anthropogenic impacts have been by far the strongest) is poorly characterized, with prior measurements made using an older technique in the 1990s on only a few samples from one ice core. No published carbon monoxide isotope measurements from northern hemisphere ice cores are currently available. Researchers on this project will collect a new large diameter ice core near Summit, Greenland using the Blue Ice Drill (BID), providing ice from 80 to 170 meters depth (air age from about 1960 to about 1600 AD). Continuous measurements of carbon monoxide concentration will provide a high-resolution record over the entire ice core and identify ice layers where carbon monoxide is well preserved. High-precision discrete analyses of carbon monoxide concentration and isotopic composition will then target ice from these layers. Continuous analyses of trace chemistry and discrete analyses of trace organics will also be conducted to establish the ice core chronology and improve understanding of mechanisms of in situ carbon monoxide production in ice. Atmospheric histories for carbon monoxide concentration and isotopic composition will be derived using a combination of firn-ice gas transport and inverse models, and the implications for pre-industrial carbon monoxide budget will be investigated with the use of a climate-chemistry model. This approach maximizes the chance of obtaining a reliable history of carbon monoxide concentration and isotopic composition through careful site selection and the application of novel ice drilling and analytical techniques. Results from the study will be made available to the scientific community and the general public through the NSIDC and NOAA Paleoclimatology data centers. The work will contribute to the training of two graduate and 2 undergraduate students, support an early career investigator, and establish several new collaborations among the investigators.

Logistics Summary:
Researchers on this collaborative project between Petrenko (1406236, Rochester, LEAD), McConnell (1406219, DRI), Mak (1405817, Stonybrook), and Tsigaridis (1404158, Columbia) will continue work begun under the lead PI's existing 14C project (1203779). The main goal of the project is to provide a first reliable atmospheric reconstruction of carbon monoxide (CO) and its isotopes from Greenland ice back to 1600 AD. During a single summer of field work, 2015, researchers will obtain up to 100 m of large diameter ice core. They will work near the historical Euro core site, at a site they are calling PLACE camp, using the Blue Ice Drill (BID) between 80 and 170 m depth. The cores will be transported via ANG to Kangerlussuaq, and then back the US on a cold deck flight for eventual storage and processing at the National Ice Cores Laboratory (NICL).

For the combined Petrenko led projects (1203779 and 1406236), CPS will provide ANG airlift for the field team and cargo; en route user days at Kangerlussuaq and Summit Station; field camp and safety equipment from the CPS inventory; construction support for camp setup / takedown and various support requirements (i.e. core storage trench, melter platform, and sample trays); provision of generator support and fuel; provision of food; CPS Camp Coordinator support; and shipment for up to 100 ice core boxes of frozen samples Summit > Kangerlussuaq > NY > NICL. IDDO will provide the drill and related drilling support while in the field. All other logistics will be organized by the researchers and paid through the grant
