The aim is to discover if rising levels of oceanic carbon dioxide will offset negative effects of ocean warming on seaweeds, using targeted physiological experiments together with novel molecular diagnostics. Seaweeds create habitats and food for shellfish and fish, and play a crucial role in long term ‘blue carbon’ storage. They are predicted to benefit from future carbon dioxide enrichment, but to test this forecast requires a detailed understanding of the mechanisms used by seaweeds to acquire dissolved inorganic carbon. The expected outcome is robust predictions of how the primary productivity of coastal waters will respond to future high carbon dioxide conditions, enabling human adaptation to environmental change.

其目的是发现海洋二氧化碳水平的上升是否会抵消海洋变暖对海藻的负面影响，使用有针对性的生理实验和新的分子诊断。海藻为贝类和鱼类提供栖息地和食物，并在长期的“蓝碳”储存中发挥着至关重要的作用。据预测，它们将受益于未来的二氧化碳富集，但要测试这一预测需要详细了解海藻获取溶解无机碳的机制。预期的成果是对沿海沃茨的初级生产力将如何应对未来高二氧化碳条件作出强有力的预测，使人类能够适应环境变化。
