Introduction
This section contains three supplementary figures used to help describe CO2 flux
estimates in the Bering Sea, including: a monthly climatology of monthly second
moments of the wind speed from the North American Regional Reanalysis (NARR)
from 2008-2012; a monthly climatology of monthly second moments of the wind
speed from the Scatterometer Climatology of Ocean Winds (SCOW) from 2008 –
2012; and a monthly climatology of gridded passive microwave percent ice
concentration data from 2008-2012 from the French Research Institute for
Exploration of the Sea (IFREMER) CERSAT archive. The NARR and CERSAT
climatologies were used in our analysis to calculate sea-air CO2 fluxes. The SCOW
climatology is provided here to contrast with the NARR product, highlighting the
absence of data north of ~60 degrees latitude.
1.1 fs01.txt Climatological monthly second moments of the wind speed from the
North American Regional Reanalysis (NARR) from 2008-2012. Wind speeds during
ice-impacted months (Dec – May) were low in areas of ice cover (compare to
Supplemental Figure 3).
2.1. fs02.txt Climatological monthly wind speeds from the Scatterometer
Climatology of Ocean Winds (SCOW) from 2008-2012. Relative to the North
American Regional Reanalysis (NARR), areal coverage is limited in the northern
region. Note that the amplitude of these winds is higher than in NARR (compare to
supplemental Figure 1), but that the qualitative patterns in wind speed for the
coverage available is similar.
3.1. fs03.pdf Monthly climatological gridded passive microwave percent ice
concentration data from the French Research Institute for Exploration of the Sea
(IFREMER) CERSAT archive. Note that monthly second moments of the wind speed
presented in Figure 1 are lower in areas of ice cover.
