Groundwater levels and temperature, Delta Junction, Interior Alaska, 2014-2016

Lowland groundwater levels and groundwater temperatures were measured continuously near the town of Delta Junction, Interior Alaska, starting in mid-December 2014. Groundwater levels were measured ~800 m east of the Delta River and ~1.6 km downstream of the Jarvis Creek-Delta River confluence (64.04N, -145.74W, 354 m.a.s.l.). Groundwater levels and temperature were measured inside an unused ~40 m deep household well with a ~15 cm diameter steel pipe and casing. Groundwater data was logged every hour on a non-vented pressure transducer, which was hung on a wire. The purpose of the dataset was to quantify the seasonal variation in lowland groundwater levels and groundwater temperatures in Interior Alaska.

本数据集于2014年12月中旬起，在阿拉斯加内陆德尔塔章克申镇附近持续开展低地地下水位与地下水温度监测。地下水位监测点位设置于德尔塔河以东约800米、贾维斯溪-德尔塔河汇流处下游约1.6公里处（北纬64.04°，西经145.74°，海拔354米）。监测工作在一口废弃家用井内进行，该井井深约40米，采用直径约15厘米的钢管作为井管与井套。地下水数据通过悬挂于钢丝上的无通气型压力换能器每小时记录一次。本数据集旨在量化阿拉斯加内陆低地地下水位与地下水温度的季节变化特征。
