海啸是对沿海地区底栖生物和海底环境造成严重破坏的巨大灾害。了解底栖生态系统如何应对这种破坏性力量以及个体物种如何受到影响具有重要的生态学意义。调查这些灾难对很少被活捉的动物的影响尤其困难。双壳类软体动物特别适合调查海啸如何影响沿海底栖生物物种，因为它们在壳中保存了环境记录，可以通过交叉比对多个个体的记录来延长时间。我们研究了长寿命蛤蚌的死壳，并利用核弹诱导的放射性碳（bomb-14C）和计算年生长增量精确地确定了死亡时间。首先，通过分析6个活体捕获的斯汀普森螺的壳，建立了一个准连续的区域炸弹- 14c记录。然后，从船古湾海底收集的27个死贝壳进行了14c测年和分析。结果表明，2011年3月11日袭击日本东北部的巨大海啸导致船本湾双壳贝大量死亡。27只蛤蜊中有9只在2011年3月的海啸中死亡，可能是在海啸沉积物掩埋后饿死的，也可能是在地震期间由于沉积物液化而暴露在海底。这项研究中使用的测年方法可以帮助我们了解低种群密度的长寿海洋生物是如何受到海啸等巨大自然灾害的影响的。
Tsunamis are huge disasters that can significantly damage benthic organisms and the sea-bottom environment in coastal areas. It is of great ecological importance to understand how benthic ecosystems respond to such destructive forces and how individual species are affected. Investigating the effect of such disasters on animals that are seldom caught alive is particularly difficult. Bivalve mollusks are especially suitable for investigating how a tsunami affects coastal benthic species because they preserve an environmental record in their shells that can be extended back in time by crossdating the records of multiple individuals. Here we studied dead shells of Mercenaria stimpsoni, a long-lived clam, and precisely determined the time of death by using nuclear bomb–induced radiocarbon (bomb-14C) and by counting annual growth increments. First, a quasi-continuous, regional bomb-14C record was created by analyzing the shells of 6 live-caught M. stimpsoni individuals. Then 27 dead shells collected from the seafloor of Funakoshi Bay were 14C-dated and analyzed. The results showed that the huge tsunami that struck northeastern Japan on 11 March 2011 caused mass mortality of this bivalve in Funakoshi Bay. Nine of the 27 clams died during the March 2011 tsunami, probably by starvation after burial by tsunami deposits or exposure above the seafloor as a result of sediment liquefaction during the earthquake. The dating method used in this study can help us understand how long-lived marine organisms with low population density are affected by huge natural disasters such as a tsunami.
