Data on hatching frequency and success from an experiment on CO2 sensitivity of Northern sand lance (Ammodytes dubius) embryos conducted in 2020

Source data of two years of experimentation on Northern sand lance (Ammodytes dubius) embryos at different temperature and pCO2 conditions. Founder adults were sampled at Stellwagen Bank National Marine Sanctuary (SBNMS) (42° 9' 58.26\" N, 70° 18' 44.1\" W). Two complementary experiments were conducted in late 2018 (E1) and 2020 (E2), each rearing newly fertilized sand lance embryos to hatch over the course of 32-65 days. This dataset includes information from the switch experiment (E2) in 2020.本数据集涵盖了两年间在不同温度与二氧化碳分压（pCO2）条件下开展的北极大沙钻鱼（Ammodytes dubius）胚胎相关实验的原始数据。实验所用的亲本成鱼采集自斯泰尔华根银行国家海洋保护区（Stellwagen Bank National Marine Sanctuary, SBNMS），采样坐标为北纬42°9'58.26"、西经70°18'44.1"。本研究于2018年末与2020年末分别开展了两项互补性实验（分别记为E1与E2），两项实验均将新受精的沙钻鱼胚胎培育至孵化，培育周期为32至65天。本数据集包含2020年开展的转换实验（E2）的相关数据。
