Davis Aerodrome Project (DAP) – Subsurface Soil Temperature Monitoring Data

The Davis Aerodrome Project (DAP) collected a range of environmental survey data over several field seasons to support a comprehensive environmental assessment of the proposed aerodrome. This data includes flora, fauna, soils, lake ecosystem, nearshore, marine, air quality and meteorological information which has been collected by a number of different methods, and extends across the current Davis Station, proposed aerodrome and supporting infrastructure footprint (Ridge Site), previous sites considered for the aerodrome (Heidemann Valley, Adams Flat), as well as locations across the Vestfold Hills away from any of the proposed developments.This dataset contains long-term subsurface soil temperature monitoring data collected for the DAP. Two monitoring stations (PDH02b and PDS03c) were established in the 2012/13 season during preliminary site investigations undertaken as part of the Capability Development Project. During this season field investigations were centred on the coastal site at Adams Flat and boreholes were located within soil-filled valleys between outcrops of bedrock in the vicinity of Dingle Road. The subsurface soil temperature monitoring boreholes were located in association with two water level monitoring sites. Automatic monitoring at the subsoil temperature monitoring sites has occurred since their establishment, up until November 2021, under the Year-Round Aviation Access (YRAA) scoping project and DAP. Boreholes were drilled to a depth of approximately 6 meters and cables, containing sensors (thermistors) positioned every meter to a depth of 5 meters, were installed. At PDH02b two separate cables, TS01 and TS03, were installed within the same borehole. At PDS03c only one cable, TS02, was installed. Sensors were programmed to record temperatures at 10-minute intervals.Data were downloaded from the dataloggers every 4-6 weeks. Once collected, the data were added to the existing dataset for each cable and the graphical analysis updated. Where outlying or spurious records were noted to significantly impact the graphed output these were removed from a copy of the data and graphs redrawn. Where data were removed, the spreadsheet contains a tab displaying the raw data as well as the processed data with outlying data points removed.

戴维斯机场项目（Davis Aerodrome Project, DAP）在多个野外调查季中收集了多类环境调查数据，以支撑对拟建机场的全面环境评估。本次采集的数据涵盖植物群、动物群、土壤、湖泊生态系统、近岸海域、海洋环境、空气质量及气象信息，采用多种不同的采集方法完成，覆盖范围包括现有戴维斯站、拟建机场及配套基础设施用地（里奇场址）、此前拟作为机场场址的区域（海德曼谷、亚当斯平原），以及韦斯特福尔丘陵（Vestfold Hills）内远离所有拟建开发项目的区域。
本数据集包含为DAP采集的长期地下土壤温度监测数据。2012/13季，作为能力开发项目的一部分开展初步场地调查期间，项目组设立了两个监测站点（PDH02b与PDS03c）。该季野外调查以亚当斯平原的沿海场址为核心，钻孔布设于丁格尔路附近基岩露头间的填土山谷内。
地下土壤温度监测钻孔与两个水位监测站点配套布设。自站点设立以来，地下土壤温度监测工作已实现自动运行，直至2021年11月，相关监测工作由全年航空准入（Year-Round Aviation Access, YRAA）范围界定项目及DAP共同推进。
钻孔钻进深度约6米，布设了搭载传感器（热敏电阻，thermistors）的电缆，传感器以每米1个的间距布置至5米深度。其中，PDH02b的同一钻孔内安装了TS01与TS03两条独立电缆；PDS03c的钻孔内仅安装了TS02一条电缆。传感器被预设为每10分钟记录一次温度数据。
数据每4至6周从数据记录仪（dataloggers）下载一次。数据采集完成后，将其添加至对应电缆的现有数据集，并更新图形分析结果。若发现异常或虚假记录对绘图输出造成显著影响，则会在数据副本中剔除此类记录并重新绘制图表。配套电子表格包含两个工作表：其一存储原始数据，其二存储剔除异常数据点后的处理后数据。
