Whelk sizes measured from 4 sites relative to tidal elevation from coastal Oregon, 2014-2015

<p>Data are from surveys in July 2014 and 2015 of whelk size distributions. Whelks were measured from apex to bottom of siphonal canal at 4 sites in haphazard quadrats until ~200 individuals of each species were measured. This sheet is the lengths of each individual whelk measured (i.e., each row is one whelk).&nbsp;</p>

本数据集源自2014年7月与2015年7月开展的峨螺（whelk）体长分布调查。研究人员在4个调查站点布设随机样方（quadrats）进行采样，直至每个物种的约200个个体均完成测量，测量指标为从壳顶（apex）至水管沟（siphonal canal）末端的体长。本工作表记录了所有被测峨螺个体的体长数据，即工作表中每一行对应1只被测峨螺。
