Milne Fiord Oceanographic Mooring, 2011-2019

A series of temperature, conductivity-temperature and conductivity-temperature-depth loggers were placed on a rope suspended from the ~1-2 m thick perennial ice surface. The lower end of the rope was weighted down. Each logger was set to record continuously (at various intervals). Temperature loggers were Onset hobo temperature loggers, and RBR TR1050s, TR1060s and SoloTs. Note, Hobo temperature loggers were placed in the ice and on a vertical stake and measured air, snow or ice temperatures. CT/CTDs were Seabird SBE37, XT-420, XR-620. Instrument number and placement varied through time 15 to 27. Each year the mooring is retrieved. Each instrument program is then downloaded, batteries and desiccant are changed, time is synced and a new program is uploaded. At the top of the mooring, there is a cross of 2x4s that attaches to a 3 m PVC stake and 3 floats. That way, the mooring can be found and recovered if the ice breaks up (although this has not occurred yet). Visits to the mooring include: May 2011 (setup), May 2012, July 2012, May 2013, July 2013, July 2014, July 2015, July 2016 July 2017, July 2018 and July 2019.

一系列温度记录仪（temperature logger）、温盐记录仪（conductivity-temperature logger, CT）及温盐深记录仪（conductivity-temperature-depth logger, CTD）被部署于悬挂于约1-2米厚多年冰表面的绳索之上。绳索下端配有配重。每台记录仪均设置为连续记录模式，记录间隔各不相同。温度记录仪采用Onset Hobo系列温度记录仪，以及RBR TR1050、TR1060与SoloT型号记录仪。需说明的是，Hobo温度记录仪被部署于冰体内部及垂直标杆上，用于测量空气、积雪或冰体温度。温盐/温盐深记录仪采用Seabird SBE37、XT-420及XR-620型号。记录仪的布设数量与位置随时间调整，区间为15至27台。每年均会回收该锚系观测系统（mooring）。随后会导出每台记录仪的存储数据，更换电池与干燥剂，同步系统时间，并上传新的记录程序。该锚系观测系统顶部设有由2×4英寸方木构成的十字形结构，该结构连接至一根3米长的PVC标杆与3个浮体。如此一来，即便冰体破裂，也可找到并回收该锚系观测系统（尽管该情况尚未发生）。对该锚系观测系统的作业时段包括：2011年5月（系统布设）、2012年5月、2012年7月、2013年5月、2013年7月、2014年7月、2015年7月、2016年7月、2017年7月、2018年7月及2019年7月。
