SGER: Carbon Isotopes of Salmon Scales: A Time History Reconstruction

SGER奖-Paul Quay/UW PI提出了一种新的方法来重建自1900年以来北太平洋亚极表层水域溶解无机碳(DIC)的14C和13C/12C记录的时间历史。重建是基于对存档的鲑鱼鳞片的碳同位素分析。这项工作的总体目标是将这一重建的记录与海洋环流模型(GCM)预测的变化进行比较，以便更好地限制GCM通量和海洋CO2吸收的预测速率。该建议符合高风险跨学科科学的类别，因此适用于SGER奖。对于PI来说，最重要的第一步是证明这项技术的可靠性，从而至少重建部分历史的碳同位素记录。有了这样的数据，PI将大大扩展我们对北太平洋环流和C输入的理解。此外，国际海洋研究所将能够展示将这一新方法应用于未来海洋科学研究的潜力。

Abstract SGER Award- Paul Quay / UW The PI proposes a novel method to reconstruct the time history of the 14C and 13C/12C record of the dissolved inorganic carbon (DIC) in the surface waters of the subpolar North Pacific since 1900. The reconstruction is based upon C isotopic analysis of archived salmon scales. The overall goal of this work is to compare this reconstructed record to changes predicted by ocean general circulation models (GCM's) in order to better constrain the GCM fluxes and predicted rates of oceanic CO2 uptake. The proposal fits the category of high-risk interdisciplinary science, and as such is appropriate for SGER award. The most important first step is for the PI to demonstrate the reliability of this technique and thus recreate at least a partial historical C isotopic record. With such data in hand the PI will extend considerably our understanding of circulation and C inputs to the N. Pacific. In addition, the PI will be in a position to demonstrate the potential for applying this novel approach to future studies in ocean sciences.
