Population structure and reproductive biology of Alviniconcha hessleri

size structure of populations (shell height in mm) and oocyte size (in µm) distribution of alviniconcha hessleri from hydrothermal vents along the mariana back-arc. individuals were collected at five vent sites in the northern and central regions of the mariana back-arc (~18.2 to 15.4° n) during the fk161129 schmidt ocean institute cruise in 2016. these data were collected through histological analyses on several individuals from each site.

本数据集记录了来自马里亚纳海沟后弧热液喷口附近的海兔孔壳（Alviniconcha hessleri）种群的大小结构（以毫米计的壳高）以及卵母细胞大小（以微米计）的分布情况。数据收集于2016年fk161129施密特海洋研究所巡航期间，在马里亚纳海沟北部和中部地区的五个喷口位置（约18.2至15.4°N纬度）。通过对各地点若干个体的组织学分析，获得了这些数据。
