LBA-ECO CD-06 Biogeochemistry of Ji-Parana River and Tributaries, Brazil: 1999-2003

This data set provides spatially extensive and temporally intensive surveys of the river biogeochemistry of the Ji-Parana River Basin in Western Amazonia, Rondonia, Brazil. The concentrations of major nutrient ions, dissolved organic and inorganic carbon, pH, temperature, dissolved oxygen, and conductivity were measured in Ji-Parana River and tributary samples at the defined seasonal or monthly intervals. Dominant landuse/landcover classes, slope, and soil cation exchange capacity are included for each of the extensive sampling locations derived from river basin and sub-basin characteristics.

Water samples were collected from 1999 to 2003 along the main stem of the Ji-Parana River as well as from the major tributaries including the Urupa. Shapefiles with the boundaries of the major sub-basins of the study area as well as the location of the sample collection points are included for the intensive and extensive sampling campaigns as well as the Urupa River campaign.

There are six comma-separated data files (.csv) and five compressed shapefiles (.zip) with this data set.

本数据集提供了亚马逊西部罗纳尼亚地区Ji-Parana河流域的河生物地球化学的广泛空间覆盖和密集时间序列调查。在定义的季节或月度间隔内，对Ji-Parana河及其支流（包括Urupa河）的水样进行了主要营养离子浓度、溶解有机和无机碳、pH值、温度、溶解氧和电导率的测量。对于每个广泛的采样地点，均包括主导土地利用/土地覆盖类型、坡度和土壤阳离子交换能力，这些数据源自河流域和子流域的特征。自1999年至2003年，在Ji-Parana河干流以及主要支流（包括Urupa河）沿线收集了水样。本数据集包含用于密集和广泛采样活动以及Urupa河活动的采样点位置的形状文件，以及研究区域主要子流域边界的形状文件。数据集包含六个以逗号分隔的数据文件（.csv）和五个压缩的形状文件（.zip）。
