Stable isotope data of sediment trap P87-12@en
收藏资源简介:
The data are stable isotope measurements (13C/12C and 15N/14N) obtained from sediment traps and stable isotope data on plankton and suspended particulate matter in the mixed layer obtained from net tows. Sediment trap data are from Station Papa (50 N, 145 W) time-series (bi-weekly) measurements in samples for the period November 1982 to the present, and from Station L (48'39'N,126'40'W) for the period October 1989 to November 1990. (Data manager's note: The author mentions sediment traps on moorings in the North Atlantic, but there is no data for these sites). Net tow data for the Pacific are from Line P (48 35 N 126 24 W to Station Papa) from cruises by the RV JOHN TULLY in Sept-Oct 1992, Feb 1993 and May 1993. New tow data for the Atlantic are from the North Atlantic transect (44 N 54 W to 32 N 11 W) from cruises by the RV HUDSON in September 1992 and May-June 1993. The data are somewhat unusual, in that they represent very specialized numbers on the isotopic composition of nitrogen and carbon in suspended particulate matter, plankton and sediment trap subsamples.
本数据集包含两类稳定同位素(stable isotope)测量数据:一类为沉积物捕获器(sediment trap)实测所得的碳同位素比值(13C/12C)与氮同位素比值(15N/14N),另一类则是通过拖网(net tow)获取的海洋混合层(mixed layer)内浮游生物与悬浮颗粒物的稳定同位素数据。 沉积物捕获器数据源自两个观测站点:帕帕站(Station Papa,北纬50°,西经145°)的序列观测为1982年11月至今的双周采样实测数据;L站(Station L,北纬48°39′,西经126°40′)的观测时段为1989年10月至1990年11月。 (数据管理员备注:原文作者提及北大西洋锚泊式沉积物捕获器相关站点,但此类站点暂无对应数据) 太平洋海域的拖网数据源自P航线(Line P,北纬48°35′、西经126°24′至帕帕站),由科考研究船RV JOHN TULLY于1992年9-10月、1993年2月及1993年5月的航次采集获取。 大西洋海域的新增拖网数据源自北大西洋断面航次(北纬44°、西经54°至北纬32°、西经11°),由科考研究船RV HUDSON于1992年9月及1993年5-6月的航次采集获取。 本数据集具有一定特殊性,其所收录的为悬浮颗粒物、浮游生物及沉积物捕获器分样品中氮与碳同位素组成的专属高精度实测数值。
