Stable isotope data of sediment trap P83-3@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.
本数据集包含两类核心数据:其一为沉积物捕集器(sediment trap)获取的稳定同位素(¹³C/¹²C与¹⁵N/¹⁴N)测量数据;其二为通过拖网采样(net tow)获取的混合层内浮游生物与悬浮颗粒物的稳定同位素数据。 沉积物捕集器数据来源于两个站位:一是帕帕站(Station Papa),坐标为50°N、145°W,其采样为每两周一次的时间序列测量,时段为1982年11月至今;二是L站(Station L),坐标为48°39′N、126°40′W,采样时段为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集器相关站点,但上述站点无可用数据。) 太平洋区域的拖网采样数据来自P线(Line P),采样范围为48°35′N、126°24′W至帕帕站,由约翰·塔利号科考船(RV JOHN TULLY)于1992年9-10月、1993年2月及1993年5月的航次获取。大西洋区域的新增拖网采样数据来自北大西洋断面,采样范围为44°N、54°W至32°N、11°W,由哈德逊号科考船(RV HUDSON)于1992年9月及1993年5-6月的航次获取。 本数据集的数据具有一定特殊性,其涵盖了悬浮颗粒物、浮游生物及沉积物捕集器子样品中氮与碳的同位素组成的专属高精度测量值。
