Stable isotope data of sediment trap P85-7@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测定数据:一类为沉积物陷阱(sediment trap)获取的碳同位素比值(¹³C/¹²C)与氮同位素比值(¹⁵N/¹⁴N)测定值;另一类为网采(net tow)获取的混合层(mixed layer)内浮游生物与悬浮颗粒物(suspended particulate matter)的稳定同位素数据。 沉积物陷阱数据来源于两个站位的时序观测:其一为帕帕站(Station Papa,50°N,145°W),其采样频率为每两周一次,时间跨度为1982年11月至今;其二为L站(Station L,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】作者提及了北大西洋锚泊沉积物陷阱的相关站位,但暂未公开对应数据。 太平洋区域的网采数据来源于P航线(Line P,从48°35′N 126°24′W至帕帕站)的三次科考航次,由“约翰·塔利号”研究船(RV JOHN TULLY)于1992年9-10月、1993年2月及1993年5月执行。 大西洋区域的新增网采数据来源于北大西洋断面(North Atlantic transect,从44°N 54°W至32°N 11°W)的两次科考航次,由“哈德逊号”研究船(RV HUDSON)于1992年9月及1993年5-6月执行。 本数据集具有一定特殊性,其涵盖的均为悬浮颗粒物、浮游生物及沉积物陷阱子样品中氮、碳同位素组成的专属高精度测定数据。
