Dissolved neodymium and hafnium isotopes and rare earth element data of near-bottom water samples from RV Meteor cruise M147@en

The dataset comprises isotope compositions of dissolved neodymium (Nd) and hafnium (Hf), together with particulate Nd and Hf isotope data from surface estuarine sediments. It further includes concentrations of rare earth elements and yttrium (REY) as well as dissolved hafnium ([Hf]) in near-bottom waters and surface sediments collected across the Amazon shelf and slope. All samples were obtained during RV Meteor cruise M147 (April–May 2018), conducted as the official process study GAPR11 within the framework of the international GEOTRACES program.本数据集涵盖溶解态钕（neodymium, Nd）与铪（hafnium, Hf）的同位素组成数据，同时包含河口表层沉积物中的颗粒态钕、铪同位素数据。此外，数据集还收录了采集自亚马孙陆架与陆坡区域的近底层海水及表层沉积物中的稀土元素与钇（rare earth elements and yttrium, REY）浓度，以及溶解态铪（[Hf]）含量。所有样品均采集于"流星号"（RV Meteor）科考航次M147（2018年4—5月），该航次作为国际GEOTRACES计划框架下的官方过程研究项目GAPR11组织实施。
