这项研究首次提出了由地中海冷水珊瑚遗址的碳酸盐累积速率补充的加积速率，考虑了三种不同的区域和地貌环境：（i）冷水珊瑚脊（阿尔沃兰海梅利拉珊瑚省东部），（ii）海底悬崖底部的冷水珊瑚碎石堆积物存款（Urania Bank，Strait of西西里）和（iii）冷水珊瑚存款植根于预定义的地形高冷水珊瑚（圣玛利亚迪莱乌卡珊瑚省，爱奥尼亚海）。各冷水珊瑚沉积物的平均沉积速率在10和530 cm kyr−1之间变化，平均碳酸盐累积速率在8和396 g cm−2 kyr−1之间变化，在东部梅利拉珊瑚区达到最大值503 g cm−2 kyr −1。与其他深水沉积环境相比，地中海冷水珊瑚遗址显示出显着更高的碳酸盐积累率，甚至在生产力最高的浅水地中海碳酸盐工厂（例如Cladocora caespitosa珊瑚礁）的范围内。专门关注冷水珊瑚的出现，地中海冷水珊瑚网站的碳酸盐积累率是在较低的范围内获得的多产的挪威珊瑚出现，但表现出比冷水珊瑚土丘关闭爱尔兰高得多的速度。这项研究清楚地表明，冷水珊瑚有可能成为地中海内重要的碳酸盐工厂和区域碳酸盐汇。此外，这些数据突出了冷水珊瑚以热带浅水珊瑚礁的速率储存碳酸盐的潜力。为了评估冷水珊瑚碳酸盐工厂对区域或全球碳酸盐/碳循环的贡献，需要更好地了解加积和碳酸盐累积速率的时空变化以及相应区域的面积估计。
This study presents aggradation rates supplemented for the first time by carbonate accumulation rates from Mediterranean cold‐water coral sites considering three different regional and geomorphological settings: (i) a cold‐water coral ridge (eastern Melilla coral province, Alboran Sea), (ii) a cold‐water coral rubble talus deposit at the base of a submarine cliff (Urania Bank, Strait of Sicily) and (iii) a cold‐water coral deposit rooted on a predefined topographic high overgrown by cold‐water corals (Santa Maria di Leuca coral province, Ionian Sea). The mean aggradation rates of the respective cold‐water coral deposits vary between 10 and 530 cm kyr−1 and the mean carbonate accumulation rates range between 8 and 396 g cm−2 kyr−1 with a maximum of 503 g cm−2 kyr−1 reached in the eastern Melilla coral province. Compared to other deep‐water depositional environments the Mediterranean cold‐water coral sites reveal significantly higher carbonate accumulation rates that were even in the range of the highest productive shallow‐water Mediterranean carbonate factories (e.g. Cladocora caespitosa coral reefs). Focusing exclusively on cold‐water coral occurrences, the carbonate accumulation rates of the Mediterranean cold‐water coral sites are in the lower range of those obtained for the prolific Norwegian coral occurrences, but exhibit much higher rates than the cold‐water coral mounds off Ireland. This study clearly indicates that cold‐water corals have the potential to act as important carbonate factories and regional carbonate sinks within the Mediterranean Sea. Moreover, the data highlight the potential of cold‐water corals to store carbonate with rates in the range of tropical shallow‐water reefs. In order to evaluate the contribution of the cold‐water coral carbonate factory to the regional or global carbonate/carbon cycle, an improved understanding of the temporal and spatial variability in aggradation and carbonate accumulation rates and areal estimates of the respective regions is needed.
