Collaborative Research: Production and Dissolution of Calcium Carbonate in the Global Ocean: A Synthesis and Modeling Project

五名首席研究人员利用他们在钙化作用、卫星算法、沉积物圈闭解释、水柱化学、沉积物地球化学和全球建模方面的专门知识，提出了一种多学科方法，旨在改善海洋中碳酸钙循环速率的不确定性。为实现这一目标，私人投资机构计划在区域和全球范围内实现以下四个目标：(1)改进对表层海洋颗粒无机碳的常量存量和钙化率的估计；(2)改进对表层CaCO3出口的估计；(3)改进对浅层(100-1000米)溶解速率的估计；以及(4)改进对深层(1000米)溶解速率的估计。这项研究的结果将是盆地规模和全球碳酸盐预算，以提高我们对碳酸盐生产、出口和海洋环境中浅水/深水溶解的了解。

ABSTRACTOCE-0136503OCE-0136541OCE-0136621OCE-0137144Combining their expertise in calcification, satellite algorithms, sediment trap interpretation, water column chemistry, sediment geochemistry and global modeling, five principal investigators propose a multidisciplinary approach aimed at improving the uncertainties in the rates of CaCO3 cycling in the ocean. To achieve this goal, the PIs plan to address the following four objectives on both a regional and a global scale: (1) improve estimates of the standing stock and calcification rates of surface ocean particulate inorganic carbon; (2) improve estimates of surface CaCO3 export; (3) improve estimates of shallow (100-1000m) dissolution rates; and (4) improve estimates of deep (1000m) dissolution rates. Results from this study will be basin-scale and global carbonate budgets to improve our understanding of carbonate production, export and shallow/deep water dissolution in the marine environment.
