Constraining rates of marine carbonate burial through geologic time is critical for interpreting reconstructed changes in ocean chemistry and understanding feedbacks and interactions between Earth's carbon cycle and climate. The Quaternary Period (the past 2.6 million years) is of particular interest due to dramatic variations in sea level that periodically exposed and flooded areas of carbonate accumulation on the continental shelf, likely impacting the global carbonate budget and atmospheric carbon dioxide. These important effects remain poorly quantified. Here, we summarize the importance of carbonate burial in the ocean–climate system, review methods for quantifying carbonate burial across depositional environments, discuss advances in reconstructing Quaternary carbonate burial over the past three decades, and identify gaps and challenges in reconciling the existing records. Emerging paleoceanographic proxies such as the stable strontium and calcium isotope systems, as well as innovative modeling approaches, are highlighted as new opportunities to produce continuous records of global carbonate burial.

全球第四纪碳酸盐埋藏：基于代理和模型的重建和持续的不确定性

通过地质时间限制海洋碳酸盐埋藏率对于解释海洋化学的重建变化以及理解地球碳循环与气候之间的反馈和相互作用至关重要。第四纪时期（过去 260 万年）特别令人感兴趣，因为海平面的剧烈变化会周期性地暴露和淹没大陆架上碳酸盐堆积的区域，可能会影响全球碳酸盐预算和大气二氧化碳。这些重要影响仍然难以量化。在这里，我们总结了碳酸盐埋藏在海洋-气候系统中的重要性，回顾了量化沉积环境中碳酸盐埋藏的方法，讨论了过去三十年重建第四纪碳酸盐埋藏的进展，并确定了协调现有记录的差距和挑战。新兴的古海洋学代理（例如稳定的锶和钙同位素系统）以及创新的建模方法被强调为产生全球碳酸盐埋藏连续记录的新机会。
