Surface temperature, surface oxygen, water clarity, water chemistry and phytoplankton chlorophyll a data from Windermere North Basin, UK, 2019-2020

This is part of an ongoing long-term monitoring dataset of surface temperature, surface oxygen, water clarity, water chemistry and phytoplankton chlorophyll a from fortnightly sampling at the North Basin of Windermere in Cumbria, England that began in 1945 for some variables. The data have been collected by the UK Centre for Ecology & Hydrology (UKCEH). The data available to download comprise surface temperature (TEMP) in degree Celsius, surface oxygen saturation (OXYG) in % air-saturation, Secchi depth (SECC) in metres, alkalinity (ALKA) in µg per litre as CaCO3 and pH. Ammonium (NH4N), nitrate (NO3N), soluble reactive phosphate (PO4P), total phosphorus (TOTP), dissolved reactive silicon expressed as SiO2 (SIO2) and phytoplankton chlorophyll a (TOCA) are all given in µg per litre. Water samples are based on a sample integrated from 0 to 7m. All data are from January 2019 until the end of 2020.

本数据集为英国英格兰坎布里亚郡温德米尔湖北盆地长期持续监测数据集的一部分，监测指标涵盖表层水温、表层溶解氧、水体透明度、水体化学性质及浮游植物叶绿素a，采用每两周一次的采样方案，其中部分指标的监测工作始于1945年。本数据集由英国生态与水文中心（UK Centre for Ecology & Hydrology, UKCEH）采集。可下载的数据集包含以下指标：表层水温（TEMP，单位：摄氏度）、表层溶解氧饱和度（OXYG，单位：空气饱和度百分比）、赛氏透明度（SECC，单位：米）、碱度（ALKA，以碳酸钙计，单位：微克/升）以及pH值。铵态氮（NH4N）、硝态氮（NO3N）、可溶性活性磷（PO4P）、总磷（TOTP）、以二氧化硅（SiO2）计的溶解性活性硅（SIO2）以及浮游植物叶绿素a（TOCA），所有指标的单位均为微克每升。水样均为0至7米深度的混合样品。本数据集涵盖的所有数据均采集于2019年1月至2020年12月期间。
