在新英格兰南部西大西洋的深海站2（DOS 2），从一块被淹没在3,600米深处11年的木块中发现了大量与木材有关的深海双壳类Idas argenteus。内壳层的醋酸酯皮显示了一系列的年生长线，这些线被用来建立壳长与年龄之间的关系。使用醋酸盐剥离技术还检查了从木板中回收的个体，这些木板也在DOS 2中部署，但浸没时间要短得多，生长线的数量通常与在底部花费的时间长度一致
A large population of the wood-associated, deep-sea bivalve Idas argenteus was recovered from a wood block submerged for 11 years at 3,600 m depth at Deep Ocean Station 2 (DOS 2) in the western Atlantic south of New England. Acetate peels of the inner shell layer revealed a series of annual growth lines which were utilized to establish a relationship between shell length and age. Individuals recovered from wood panels also deployed at DOS 2 but submerged for much shorter periods were also examined using the acetate peel technique, and the number of growth lines generally coincided with the length of time spent on the bottom
