Stable isotope data of Line P: LARPARA

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.本数据集包含两类测定数据：一是从沉积物陷阱（sediment traps）获取的稳定同位素（stable isotope）比值，具体为13C/12C与15N/14N；二是通过网采（net tows）获得的混合层（mixed layer）内浮游生物（plankton）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监测站位：Papa站（50°N, 145°W）的时间序列（time-series）采样，该采样采用双周（bi-weekly）监测频率，时段为1982年11月至今；以及L站（48°39′N, 126°40′W）的采样，时段为1989年10月至1990年11月。（数据管理者备注：作者提及了北大西洋锚泊沉积物陷阱，但上述站位暂无对应数据。）太平洋海域的网采数据来自P航线（Line P，站位范围为48°35′N, 126°24′W至Papa站），由约翰·塔利号（RV JOHN TULLY）调查船于1992年9-10月、1993年2月及1993年5月的航次采集获得。大西洋海域的新增网采数据来自北大西洋断面（站位范围为44°N, 54°W至32°N, 11°W），由哈德逊号（RV HUDSON）调查船于1992年9月及1993年5-6月的航次采集获得。本数据集具有一定特殊性，其收录了悬浮颗粒物、浮游生物及沉积物陷阱次级样品中氮、碳同位素组成的专属测定数据。
