| Zusammenfassung |
| We present the first year-long subpolar trans-Atlantic set of surface
seawater CO2 fugacity (fCO2sw) data. The data were
obtained aboard the MV Nuka Arctica in 2005 and provide a quasi-continuous picture of the
fCO2sw variability between Denmark and Greenland.
Complementary real-time high-resolution data of surface chlorophyll-a (chl-a)
concentrations and mixed layer depth (MLD) estimates have been collocated
with the fCO2sw data.
Off-shelf fCO2sw data exhibit a pronounced seasonal
cycle. In winter, surface waters are saturated to slightly supersaturated
over a wide range of temperatures. Through spring and summer,
fCO2sw decreases by approximately 60 μatm,
due to biological carbon consumption, which is not fully counteracted by the
fCO2sw increase due to summer warming. The changes are
synchronous with changes in chl-a concentrations and MLD, both of which are
exponentially correlated with fCO2sw in off-shelf
regions. |
