Isotopic composition of particulates from sediment trap, northern Gulf of Mexico, August 25, 2010 - March 18, 2016

This data sets contains sediment trap particulates isotopic composition from three stations. The DWH sediment trap site (Deep Water Horizon, also referred to as R/V Oceanus Site 26, or OC-26; 28°40'N, 88°21.6'W; 1660 m deep). The Seep site sediment was located near a large natural hydrocarbon seep, GC-600, (27°22.5’N, 90°30.6’W; 1380 m deep). The reference site was located is located in the Atwater Valley lease block and approximates a reference or background site (Reference site, (AT357, 27°31.5 N, 89°42.6 W; 1160 m deep). The data are organized by site, date (Month/day/year = M/D/Y) of the start of the collection period which lasted about 18 days, and by isotope. Three isotopes are reported, D14C, d13C and d34S.本数据集包含三个站位的沉积物捕获器（sediment trap）颗粒物同位素组成数据。DWH沉积物捕获器站位即深水地平线（Deep Water Horizon），亦称为R/V 俄刻阿诺斯号26号站位（OC-26），坐标为北纬28°40′，西经88°21.6′，水深1660米。渗漏区站位的沉积物采集自一处大型天然烃类渗漏区GC-600附近，坐标为北纬27°22.5′，西经90°30.6′，水深1380米。参照站位位于阿特沃特谷租赁区块，作为背景参照站位，编号为AT357，坐标为北纬27°31.5′，西经89°42.6′，水深1160米。本数据集按站位、采集周期起始日期（格式为月/日/年，即M/D/Y）编排，单次采集周期时长约18天，并按同位素类型分类。本次报道的同位素共3种：Δ¹⁴C、δ¹³C及δ³⁴S。
