Temperature, pH, DO, and salinity data from Mumford Cove, Connecticut, USA from 2015-2022

Despite their importance for research and environmental protection, there's still a shortage of high quality and high-resolution temperature, pH, and oxygen data particularly in shallow coastal habitats. We monitor five important environmental parameters (i.e., depth, temperature, salinity, pH, and dissolved oxygen) at 30 minute intervals in Mumford Cove, CT (41 degrees 19'25"N, 72 degrees 01'07"W), a small (2 km N-S × 0.5 km E-W), shallow (1-5 meters), cone-shaped embayment opening to northeastern Long Island Sound, with protected marsh habitat along its western side, marsh and beach habitat along its eastern side, and an extensive seagrass (Zostera marina) cover. Continuous monitoring is achieved by swapping identical and recalibrated probes (Eureka Manta Sub2) every 3-5 weeks.

尽管此类数据对科研与环境保护均具有重要价值，但当前仍缺乏高质量、高分辨率的温度、pH值与溶解氧监测数据，在浅海沿岸生境中这一缺口尤为显著。本数据集在康涅狄格州马姆福德湾（Mumford Cove，北纬41°19′25″，西经72°01′07″）开展了每30分钟一次的连续监测，共记录5项关键环境参数，分别为水深、水温、盐度、pH值及溶解氧。该海湾为南北长2千米、东西宽0.5千米的小型浅海锥形湾，水深1至5米，开口连通东北端的长岛湾；其西侧分布有受保护的沼泽生境，东侧则兼有沼泽与海滩生境，全域覆盖有大面积的鳗草（Zostera marina）海草床。为保障监测的连续性，研究人员每3至5周便会更换经过重新校准的同款探头（Eureka Manta Sub2）。
