Resolving Heterogeneity in CO₂ Uptake Potential in the Greenland Coastal Ocean.

ABSTRACT: The oceans play a pivotal role in mitigating climate change by sequestering approximately 25% of annually emitted carbon dioxide (CO₂). High-latitude oceans, especially the Arctic continental shelves, emerge as crucial CO₂ sinks due to their cold, low saline, and highly productive ecosystems. However, these heterogeneous regions remain inadequately understood, hindering accurate assessments of their carbon dynamics. This study investigates variation in pCO₂ levels during peak ice sheet melt, in the Greenland coastal ocean and estimates rates of air-sea exchange across 6° of latitude. The East and West coast of Greenland displayed distinct regions with unique controlling factors. Though, both coasts represent CO₂ sinks in summer. Geographic
