Dissolved organic and inorganic carbon in a Southeast Alaskan watershed (2021)

Data from high frequency sampling of multiple carbon forms were collected in a predominately rain-fed watershed in Southeast Alaska during the main run-off season (May-October 2021). The dataset includes hourly measurements of stream temperature, specific conductivity, turbidity, and fluorescent dissolved organic matter, point samples of dissolved organic carbon (DOC), alkalinity/dissolved inorganic carbon (DIC), delta 13C DIC values, and modeled hourly DOC values. The objective of this study was to collect data on carbon export and flow to model watershed export of carbon forms.

2021年5月至10月的主径流期内，本研究团队在阿拉斯加东南部以雨水补给为主的流域中，针对多种碳形态开展高频采样并获取相关数据。本数据集包含溪流水温、比电导率、浊度及荧光溶解性有机物的逐小时监测数据，同时涵盖溶解性有机碳（dissolved organic carbon, DOC）、碱度/溶解性无机碳（dissolved inorganic carbon, DIC）、δ¹³C-DIC值的定点采样数据，以及模拟生成的逐小时DOC浓度值。本研究的核心目标为采集碳输出与径流相关数据，以构建流域碳形态输出模拟模型。
