Hindcast of the alkalinity addition field trial in Halifax Harbour, Canada (Fall 2023) – Sensitivity tests: Seabed loss

The dataset provides a sensitivity test (20% seabed loss of particulate feedstock) to the simulation of the alkalinity addition experiment that was carried out in the harbour in the Fall 2023. The model couples circulation with inorganic carbon chemistry and includes tracers to simulate the fate of the alkalinity addition (particulate and dissolved phases) and its effects on inorganic carbon parameters and air-sea CO2 fluxes in the Halifax Harbour and the inner Scotian Shelf. Results of the 6-month simulations (October 1, 2023 to April 1, 2024) were used to determine the sensitivity of the hindcast to the loss of feedstock in the sediment.

该数据集提供了对2023年秋季在港口进行的碱性物质添加实验模拟的敏感性测试（海底物质原料损失20%）。模型将环流与无机碳化学相结合，并包含示踪剂以模拟碱性物质添加（颗粒和溶解相）的归宿及其对无机碳参数及哈利法克斯港和内斯科特浅滩的海气CO2通量的影响。6个月的模拟结果（2023年10月1日至2024年4月1日）被用于确定逆推预测对沉积物中原料损失敏感性的影响。
