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

ABSTRACTOCE-0136503OCE-0136541OCE-0136621OCE-0137144五名主要研究人员结合他们在钙化、卫星算法、沉积物陷阱解释、水柱化学、沉积物地球化学和全球建模方面的专业知识，提出了一种多学科方法，旨在改善海洋中 CaCO3 循环速率的不确定性。 为了实现这一目标，PI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存量和钙化率的估计； (2) 改进地表 CaCO3 出口的估算； (3) 改进浅层（100-1000m）溶解速率的估计； (4) 改进对深部（1000m）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，以提高我们对海洋环境中碳酸盐生产、出口和浅/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.
