Nutrients and other data from bottle, CTD, XBT, and buoy casts from 01 January 1999 to 31 December 1999 (NODC Accession 0000398)

Nutrients, temperature profile, zooplankton biomass, and other data were collected from the CHOFU MARU, SHUMPU MARU, SEIFU MARU, and KEIFU MARU from January 1, 1999 to December 31, 1999. Data were submitted by the Japan Meteorological Agency using bottle, CTD, XBT, and buoy casts in the North Pacific Ocean. Nutrients parameters include nitrate, oxygen, phosphate, and silicate.1999年1月1日至1999年12月31日，长富丸（CHOFU MARU）、春富丸（SHUMPU MARU）、清富丸（SEIFU MARU）及庆富丸（KEIFU MARU）四艘科考船在北太平洋海域开展观测作业，通过采水器、温盐深剖面仪（CTD）、投弃式温深仪（XBT）与浮标观测手段，采集得到营养盐、温度剖面、浮游动物生物量及其他相关数据。本次观测数据由日本气象厅（Japan Meteorological Agency）整理提交，其中涉及的营养盐参数涵盖硝酸盐、溶解氧、磷酸盐及硅酸盐。
