| Zusammenfassung |
| We present results of the CO2/carbonate system from the BIOSOPE cruise
in the Eastern South Pacific Ocean, in an area not sampled previously. In
particular, we present estimates of the anthropogenic carbon
(C>TrOCAant) distribution in the upper 1000 m of this
region using the TrOCA method. The highest concentrations of
CTrOCAant found around 13° S, 132° W and
32° S, 91° W, are higher than 80 μmol.kg−1 and 70 μmol.kg−1,
respectively. The lowest concentrations are observed below
800 m depth (≤2 μmol.kg−1) and within the Oxygen Minimum
Zone (OMZ), mainly around 140° W (<11 μmol.kg−1). As a result
of the anthropogenic carbon penetration there has been decrease in pH by
over 0.1 on an average in the upper 200 m. This work further improves our
understanding on the penetration of anthropogenic carbon in the Eastern
Pacific Ocean. |
