Funds are requested to purchase an autonomous system that will allow direct and accurate measurements of the carbon dioxide partial pressure in air (pCO2-air) and (sea)water (pCO2-water). Access to such a system is critical to the pursuit of a large component of my proposed research program as well as ongoing and planned student research projects. The system will be deployed for punctual or continuous measurements along cruise tracks in the St. Lawrence (river, estuary, gulf), its tributaries (e.g., Saguenay Fjord) and in Canadian Arctic waters. It will also be used to measure the accumulations of metabolic CO2 in the hypoxic bottom waters of the Lower St. Lawrence Estuary.

需要资金购买一个自主系统，该系统将能够直接准确地测量空气（pCO2-空气）和（海水）水（pCO2-水）中的二氧化碳分压。访问这样的系统对于实现我提出的研究计划的大部分内容以及正在进行和计划中的学生研究项目至关重要。该系统将部署在圣劳伦斯河（河流、河口、海湾）及其支流（例如萨格奈峡湾）和加拿大北极水域的巡航轨道上进行准时或连续测量。它还将用于测量圣劳伦斯河口下游缺氧底层水中代谢二氧化碳的积累。
