Stable isotope data of net tows during HUDSON cruise HUD92/37@en

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实测数据：其一为沉积物捕集器（sediment trap）获取的碳同位素（¹³C/¹²C）与氮同位素（¹⁵N/¹⁴N）观测值；其二为网采（net tow）获取的混合层（mixed layer）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监测站位：帕帕站位（Station Papa，50°N，145°W）的时序采样始于1982年11月，采样频率为每两周一次，观测持续至今；L站位（Station L，48°39′N，126°40′W）的采样时段为1989年10月至1990年11月。 【数据管理备注】数据集作者提及了北大西洋锚泊式沉积物捕集器站位，但该类站点暂未提供对应数据。 太平洋海域的网采数据来源于JOHN TULLY号科考船（RV JOHN TULLY）于1992年9—10月、1993年2月及1993年5月执行的P断面（Line P，48°35′N，126°24′W至帕帕站位）科考航次。 大西洋海域的新增网采数据来源于HUDSON号科考船（RV HUDSON）于1992年9月及1993年5—6月执行的北大西洋断面科考航次，断面范围为44°N，54°W至32°N，11°W。 本数据集具有一定特殊性，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、碳同位素组成的专属实测数据。
