| Zusammenfassung |
| A new atmospheric measurement station has been established on the North Sea
oil and gas production platform F3, 200 km north off the Dutch coast
(5°51' N, 4°44' E). Atmospheric concentrations of O2 and
CO2 are continuously measured using fuel cell technology and compact
infrared absorption instruments, respectively. Furthermore, the station
includes an automated air flask sampler for laboratory analysis of the
atmospheric concentrations of CO2, CH4, CO and O2 and isotope
measurements of δ13C, δ18O and Δ14C
from CO2. This station is the first fixed sea based station with
on-site continuous O2 and CO2 measurements and therefore yields
valuable information about the CO2 uptake in coastal marine regions,
specifically the North Sea. This paper presents the measurement station and
the used methodologies in detail. In comparison to land-based stations, the
data show low day-to-day variability, as they are practically free of
nightly inversions as well as human influences, due to the station's
remoteness. Therefore, the data set collected at this measurement station
serves directly as background data for the coastal northwest European
region. Additionally, the first data are presented showing the seasonal
cycle as expected during August 2008 through June 2009. Furthermore, some
short-term O2 and CO2 signals are presented. The observations at
the platform include several large and fast changing negative atmospheric
O2 excursions without an accompanying change in the CO2 signal,
which most likely indicate marine O2 uptake. |
