Lab incubations of mussels (Mytilus californianus) examining the influence of simulated abrasion of periostracum on external shell dissolution at Marshall Gulch Beach, CA from August 2021 to March 2022

These data build off of experimental incubations described in Dataset 1. Given that the periostracum can be eroded over time, we were interested in whether the abrasion of the periostracum by sand of differing coarseness might separately influence dissolution rates under corrosive seawater conditions. Therefore, we conducted incubations of abraded California mussel valves, Mytilus californianus, (in addition to unsanded control valves) and measured dissolution rates as a function of sand paper grit coarseness (pH = 7.4). This dataset represents shell dissolution data of California Mussels from lab experiments conducted at the Bodega Marine Laboratory, University of California, Davis in August 2022. For the current study, adult mussels (42 - 64 mm in length) were collected from Marshall Gulch, California (38.369738 °N, -123.073921 °W) between August 2021 and March 2022 and transported immediately to the University of California Davis’ Bodega Marine Laboratory (< 30 min distance), in Bodega Bay, California. Mussels were held in filtered, flow-through seawater and fed ad libitum until used in experiments.

本数据集基于数据集1中记载的实验培养研究构建。鉴于壳皮层（periostracum）会随时间发生侵蚀，我们旨在探究不同粒度砂粒对壳皮层的磨蚀作用，是否会在腐蚀性海水环境下单独影响贝壳溶解速率。因此，我们对经过磨蚀处理的加州贻贝（Mytilus californianus）壳瓣开展了培养实验，并设置未经过砂磨处理的对照组壳瓣，同时以砂纸粒度为变量测定溶解速率，实验pH值设定为7.4。本数据集收录了2022年8月于加州大学戴维斯分校博德加海洋实验室开展的室内实验中，加州贻贝的贝壳溶解速率数据。

本研究所用的成年贻贝（壳长42~64 mm）于2021年8月至2022年3月间采自加利福尼亚州马歇尔古尔奇（坐标38.369738°N，-123.073921°W），并在采集后立即转运至位于加州博德加湾的加州大学戴维斯分校博德加海洋实验室（转运时长不足30分钟）。实验前，贻贝被饲养于经过过滤的流通式海水中，并自由摄食直至实验开展。

数据集1：2021年8月至2022年3月间，于加州马歇尔古尔奇海滩开展的室内培养实验，研究壳皮层（periostracum）覆盖度与pH值对加州贻贝（Mytilus californianus）贝壳外部溶解过程的影响（相关数据集详见BCO-DMO）。
