Oyster shell heights in 2015-2016 among previously documented oiled and non-oiled reefs in Louisiana, Alabama, and the Florida panhandle

Shell heights of up to 20 live oysters per size class (spat, seed, market) found in oyster reefs sampled in the early fall (September/October) and spring (April/May) in 2015-2016. Four embayments were sampled from Louisiana to the Florida panhandle, with sites that were previously oiled or non-oiled after the Deep Water Horizon Oil Spill. Within oiled and non-oiled sites, oyster quadrat samples were taken from intertidal, nearshore (along the marsh edge) and subtidal areas, and also from mesohaline and high salinity sites. The top 10 cm of material was collected from the quadrats and returned to the lab for measurement of shell height by calipers.

本数据集包含2015-2016年早秋（9月/10月）与春季（4月/5月）采集的牡蛎壳高数据：样本取自各地牡蛎礁，每个规格等级的活体牡蛎（稚贝（spat）、幼贝（seed）、商品贝（market））最多选取20只用于测量。采样区域覆盖从路易斯安那州至佛罗里达狭长地带的4处海湾，所有采样点均为深水地平线漏油事件（Deep Water Horizon Oil Spill）后曾受油污污染或未受油污污染的区域。在受油污污染与未受污染的采样点中，研究人员分别从潮间带、近岸（潮滩沿线）、潮下带区域，以及中盐度（mesohaline）和高盐度生境采集牡蛎样方（quadrat）样本。从样方中采集表层10厘米的样品带回实验室，使用游标卡尺（calipers）测量牡蛎壳高。
