Metadata for targeted genotyping of green crabs collected in the northeast Pacific from Aug 2016 to Oct 2022

This project explores genetic changes in the invasive European green crab (Carcinus maenas) in the northeast Pacific, using targeted genotyping of SNPs identified in prior high-resolution population genomics in the region. It tracks the early stages of green crab invasion into a new environment, particularly through repeated sampling of multiple size-classes of crabs from the same sites over multiple years. Samples span time and space across the species range in the northeast Pacific, with a focus on the coast of Washington and Oregon. This dataset includes individual collection and accession metadata for 1,662 crabs, for which raw demultiplexed reads are archived at GenBank's SRA under BioProject PRJNA1177418.本研究针对东北太平洋区域的入侵性欧洲绿蟹（*Carcinus maenas*）的遗传变异展开探究，采用该区域此前高分辨率群体基因组学研究中鉴定得到的单核苷酸多态性（Single Nucleotide Polymorphism，SNP）进行靶向基因分型。本研究追踪绿蟹入侵全新环境的早期进程，尤其通过多年间对同一采样点位内不同体型等级的蟹类开展重复采样完成。采样覆盖东北太平洋该物种分布范围的时空维度，研究重点聚焦于华盛顿州与俄勒冈州沿岸区域。本数据集包含1662只绿蟹的个体采集信息与入库元数据，其已去多路复用的原始测序读段已存档于GenBank的序列读取存档（Sequence Read Archive，SRA），所属生物项目编号为PRJNA1177418。
