Macquarie Harbour dissolved oxygen and temperature monitoring data from HOBO loggers (2017-2018)

Sustainable finfish aquaculture is dependent on a benthic environment that can assimilate and process farm particulate wastes. In Macquarie Harbour, bottom and mid water Dissolved Oxygen levels have reached very low levels, which is associated with an increase in the presence of bacterial mats and a significant decline in the abundance and diversity of benthic fauna. Dissolved Oxygen levels are a major determinant of the response of benthic communities in the harbour over timescales of months to years.This dataset consist of dissolved oxygen (DO) and temperature data collected using HOBO Dissolved Oxygen loggers (U26-001) deployed at two locations in Macquarie Harbour, Tasmania under FRDC project 2016-067.

可持续海水鱼类养殖依赖于能够同化并处理养殖颗粒物废弃物的底栖环境。在塔斯马尼亚州麦夸里港，底层与中层水体的溶解氧（Dissolved Oxygen）水平已降至极低，这与细菌垫的大量滋生以及底栖动物群的丰度和多样性显著下降密切相关。在数月至数年的时间尺度下，溶解氧水平是该港底栖群落响应变化的主要决定因素。本数据集包含溶解氧（DO）与温度数据，这些数据由部署在塔斯马尼亚州麦夸里港两个采样点位的HOBO溶解氧记录仪（U26-001）采集，相关工作隶属于FRDC项目2016-067。
