Estuarine water quality from "processed" environmental sensor data, 2019–2022.

Climate change is accelerating glacial melt in Gulf of Alaska watersheds and concomitant changes in runoff will affect coastal and estuarine habitat dynamics. This dataset consists of water quality measurements in Southeast and Southcentral Alaskan estuaries. Southeast Alaska sites were located in Gastineau Channel and Lynn Canal, near Juneau, and Southcentral Alaska sites were in Kachemak Bay, near Homer. Watersheds adjacent to estuary sites varied in their degree of glacierization (i.e., contemporary ice cover), ranging from 0% to 60% glacier cover. Estuary sites were sampled between April and October in 2019–2022. These data include sensor measurements of temperature, conductivity, salinity, dissolved oxygen, irradiance, and pressure (depth) recorded at 15-minute intervals by in situ sensor arrays. They also include point data taken on sampling days of temperature, salinity, conductivity, and turbidity. These data were collected as part of the Alaska EPSCoR Phase 5 “Fire and Ice” Program by the EPSCoR Coastal Margins team. --- This metadata record was created by Anne Beaudreau, Associate Professor, University of Alaska Fairbanks, in Oct–Nov 2020. Following Beaudreau's departure from UAF in December 2020, it has been further developed and maintained by Brenda Konar, Scott Gabara, and Brian Ulaski from the EPSCoR Coastal Margins team. Beaudreau may be contacted with questions regarding the metadata record or Juneau 2019–2020 data at [e-mail]. --- This folder contains all "processed" environmental sensor data from intertidal and fish sampling sites in both regions from 2019–2022. The Sensor Data folders have all the sensor data (temperature, salinity, dissolved oxygen, PAR, and TDR-time depth recorders for sensors that were truly intertidal and would go dry). These data were collected using various data loggers from the first sampling month of the year (usually May) to the last (usually September). These data can be found in their "raw" state, "processed" state, and "final" state. Please use the final state for analysis.

气候变化正加速阿拉斯加湾流域的冰川消融，随之而来的径流变化将影响海岸与河口栖息地的动态演变。本数据集涵盖阿拉斯加东南部与中南部河口的水质监测数据。阿拉斯加东南部的监测点位位于朱诺附近的加斯蒂诺海峡（Gastineau Channel）与林恩运河（Lynn Canal），中南部阿拉斯加的监测点位则位于荷马附近的卡彻马克湾（Kachemak Bay）。河口监测点位毗邻的流域，其冰川化程度（即当前冰盖覆盖率）差异显著，冰川覆盖率介于0%至60%之间。河口监测点位的采样时段为2019年至2022年的4月至10月。本数据集包含原位传感器阵列（in situ sensor arrays）以15分钟为间隔记录的多项传感器监测数据，包括温度、电导率、盐度、溶解氧、辐照度与压强（水深）。同时还包含采样当日获取的温度、盐度、电导率与浊度点位数据。此类数据由EPSCoR海岸边缘团队作为阿拉斯加EPSCoR第五阶段"火与冰"（Fire and Ice）计划的一部分采集所得。
——本元数据记录由阿拉斯加大学费尔班克斯分校副教授安妮·博德罗（Anne Beaudreau）于2020年10月至11月编制。2020年12月博德罗离开阿拉斯加大学费尔班克斯分校（UAF）后，本元数据记录由EPSCoR海岸边缘团队的布伦达·科纳尔（Brenda Konar）、斯科特·加巴拉（Scott Gabara）与布莱恩·乌拉斯基（Brian Ulaski）进一步开发并维护。若您对元数据记录或朱诺地区2019年至2020年的数据有疑问，可通过邮箱[e-mail]联系博德罗。
——本文件夹包含2019年至2022年两个区域潮间带与鱼类采样点位的所有"已处理"环境传感器数据。传感器数据文件夹包含全部传感器监测数据，包括温度、盐度、溶解氧、光合有效辐射（PAR），以及针对真正处于潮间带且会暴露于空气中的传感器所使用的时间深度记录仪（TDR）相关数据。此类数据通过各类数据记录仪采集，采集时段为每年首个采样月（通常为5月）至末次采样月（通常为9月）。此类数据分为"原始""已处理"与"最终"三种版本，请使用最终版本开展分析工作。
