Soil N pools and process rates for catenas at Caribou-Poker Research Watersheds and the Kuparuk River

Data describe soil NH4+ and NO3- pools, potential rates of denitrification and nitrification, and net N mineralization and nitrification. Soil pH, moisture, and organic matter are also included. Soils were sampled along a hillslope catena at hillslope, toeslope, and valley bottom locations and resolved to 5 cm depth increments. One hillslope at Carbiou-Poker Creeks Research Watersheds and one hillslope within the upper Kuparuk River basin were sampled. Samples were collected August 2009.

本数据集涵盖土壤铵态氮（NH4+）、硝态氮（NO3-）库容量，反硝化作用与硝化作用的潜在速率，以及净氮矿化与净硝化速率相关数据，同时收录土壤pH值、含水率与有机质含量指标。采样沿坡地土链（hillslope catena）设置，涵盖坡肩、坡趾与谷底三类点位，土壤样品按5cm深度间隔分层采集。本次采样分别于卡比乌-波克里溪研究流域的一处坡地，以及上库帕鲁克河流域内的一处坡地开展，样品采集时间为2009年8月。
