The ocean carbon sink under record-high sea surfacetemperatures in 2023/24 Open
In 2023, sea-surface temperatures (SST) reached record highs. Historically, the years with highest global mean SST anomalies were associated with a slight increase in oceanic CO₂ uptake, primarily due to reduced CO2 outgassing from t…

Compensatory Mechanisms Reduce ENSO-driven Nitrous Oxide Emission Variability in the Eastern Tropical Pacific Open
Nitrous oxide (N2O) is a potent greenhouse gas, with the Eastern Tropical Pacific (ETP) being a hotspot of N2O emissions due to high N2O production in the oxygen minimum zones (OMZs). However, N2O emissions in this region remain poorly con…

Unexpected decline of the ocean carbon sink under record-high sea surface temperatures in 2023 Open
In 2023, sea-surface temperatures (SST) reached record highs. Based on historical responses, this SST anomaly would suggest an increased oceanic CO2 uptake (-0.11±0.03 PgC yr-1). In contrast, our observation-based estimates reveal that the…
