Dasgupta/ClassThis award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-2).Fund are provided for conducting high-pressure experiments to investigate the fate of sediments as they are progressively subducted to greater depths. In particular, two major questions are addressed that are relevant to the chief goals of the Subduction Factory initiative of MARGINS: (1) What is the effect of CO2 (in the form of carbonates) on the melting behavior of subducting sediments, and (2) What is the role of carbonated sediment melting on mass transfer and mass balance of major, trace, and volatile elements across the subduction factory?Broader impacts include support of a new young investigator and a female soft-money researcher (LDEO). It would also support a graduate student at Rice. And also involve undergraduate students in aspects of the research.

Dasgupta/Class 该奖项根据 2009 年美国复苏和再投资法案（公法 111-2）提供资金。该基金用于进行高压实验，以调查沉积物逐渐潜入更深深度时的命运。 特别是，解决了与 MARGINS 俯冲工厂计划主要目标相关的两个主要问题：(1) 二氧化碳（以碳酸盐的形式）对俯冲沉积物的熔化行为有什么影响，以及（2 ) 碳化沉积物熔化对俯冲工厂中主要元素、微量元素和挥发性元素的质量传递和质量平衡有何作用？更广泛的影响包括新的年轻调查员和女性软货币研究员 (LDEO) 的支持。它还将支持莱斯大学的一名研究生。并且还让本科生参与研究的各个方面。
