The program will develop and deploy a sophisticated, unmanned observatory in the Labrador Sea and autonomous sensor systems on commercial vessels to investigate high frequency variations of CO2, O2, nutrients and biological properties over an annual cycle. The data will reveal how, and how fast oxygen is supplied from the atmosphere to the deep ocean, and how the Northwest Atlantic Ocean sequesters vast quantities of human-derived CO2. Complementary measurements and experiments in a fjord adjacent to Halifax, Nova Scotia will unravel complex controls on microbial and chemical processes which transform nitrogen-containing compounds and naturally-produced ozone-destroying gases within the ocean.

该项目将在拉布拉多海开发和部署一个复杂的无人观测站，并在商业船只上部署自主传感器系统，以调查二氧化碳、氧气、营养物质和生物特性在一年周期内的高频变化。这些数据将揭示大气向深海提供氧气的方式和速度，以及西北大西洋如何吸收大量人为产生的二氧化碳。在新斯科舍省哈利法克斯附近的峡湾进行的补充测量和实验将揭示对微生物和化学过程的复杂控制，这些过程转化了海洋中含氮化合物和自然产生的破坏臭氧的气体。
