冰川和冰盖被认为是全球生物地球化学循环的重要组成部分。化学传感器在冰冻圈中具有巨大的监测潜力,可用于许多感兴趣的分析物,但由于融水寒冷,浑浊,经历冻融循环并且显示低离子强度和目标分析物浓度,因此它们通常不适合部署。在这里,我们回顾了目前可用于测量生物地球化学重要分析物的态势化学传感器,并评估了它们的部署适用性。这些包括溶解氧和pH值等标准参数,以及宏量营养素(硝酸盐/亚硝酸盐和磷酸盐)、微量营养素(铁和锰)和生物气体(甲烷)。在没有商业替代品可用的情况下,我们讨论了目前正在开发的传感器,以及它们在这些极端环境中的适用性。所提供的信息对未来的极地环境科学,以及从极端的、难以接近的冰下环境中获得实地数据的最终目标具有重要意义。
Glaciers and ice sheets are recognised as important components of global biogeochemical cycles. Chemical sensors have great potential forin situmonitoring in the cryosphere and are available for many analytes of interest, but they are frequently unsuitable for deployment since meltwaters are cold, turbid, experience freeze-thaw cycles and display low ionic strength and concentrations of target analytes. Here, we reviewin situchemical sensors currently available for measurement of biogeochemically important analytes and assess their suitability for deployment. These include standard parameters such as dissolved oxygen and pH, along with macronutrients (nitrate/nitrite and phosphate), micronutrients (iron and manganese) and biogenic gases (methane). Where no commercial alternatives are available, we discuss sensors currently in development, and their applicability to these extreme environments. The information presented has great relevance for future science in polar environments, and for the ultimate goal of obtainingin situdata from extreme, inaccessible subglacial environments.
