Here, I present a first-of-its-kind air-sea CO₂ flux parameterization for a macroalgal habitat (Helgoland, DE), and use it to show how much gas-transfer uncertainty matters for #oceanCDR carbon crediting.
Key finding: uncertainty in gas transfer physics alone can shift carbon removal accounting by as much as the operational emissions of the entire seaweed farm.
I also propose a simple framework to quantify the "risk of incomplete equilibration", which can help future #MRV systems account for this uncertainty.
