Deep Arctic Ocean Canada Basin Mooring Data - 2

Moored temperature, salinity and pressure data from one location in the deep (is greater than 2000 m) Canada Basin. Data were collected as an extension of the Beaufort Gyre Observing System (BGOS, http://www.whoi.edu/beaufortgyre/) on mooring D. These and shallower measurements on the same mooring are available also at the BGOS website. The array of instruments at fixed depths on the mooring consisted of: 12 temperature sensors (TR-1050 RBR Ltd, Matlab file variables t1x [2489 m], t2x [2499 m], t3x [2509 m], t4x [2519 m], t5x [2529 m], t6x [2539 m], t7x [2559 m], t8x [2569 m], t9x [2579 m], t10x [2589 m], t11x [2599 m], t12x [2639 m]), two temperature, conductivity and pressure recorders (XR-420CTD RBR Ltd, Matlab file variables txr1, pxr1, sxr1 [temperature, pressure, salinity at 2549 m], txr2, pxr2, sxr2 [temperature, pressure, salinity at 2664 m]), one temperature, conductivity recorder (XR-420CT RBR Ltd, Matlab file variables txr, sxr [temperature, salinity at 2789 m]) and a temperature, conductivity recorder (Sea-Bird SBE37, Matlab file variables tsbe, ssbe [temperature and salinity at 2439 m]). Other variables in the Matlab file are vectors containing Matlab serial date numbers corresponding to the temperature, pressure, salinity time series. tvec for the TR-1050 instruments, tvecxr for all XR-420 instruments, tvecsbe for the SBE37 time series. No post-cruise calibration was possible since all instruments were re-deployed in August 2008. Calibrations were made using values from a calibrated conductivity, temperature, and depth (CTD) profile taken upon deployment at the known depths of the moored instruments.

加拿大海盆（水深大于2000米）单点锚系观测的温度、盐度与压力数据。本数据集为波弗特环流观测系统（Beaufort Gyre Observing System, BGOS，网址：http://www.whoi.edu/beaufortgyre/）在D号锚系上的延伸观测项目所采集的数据。该锚系上的此类数据及浅水深测量数据同样可于BGOS官网获取。
该锚系固定深度布设的仪器阵列包括：12台TR-1050型温度传感器（RBR有限公司生产，Matlab文件变量为t1x[水深2489米]、t2x[2499米]、t3x[2509米]、t4x[2519米]、t5x[2529米]、t6x[2539米]、t7x[2559米]、t8x[2569米]、t9x[2579米]、t10x[2589米]、t11x[2599米]、t12x[2639米]）；2台XR-420CTD型温盐压记录仪（RBR有限公司生产，Matlab文件变量txr1、pxr1、sxr1对应2549米水深处的温度、压力、盐度，txr2、pxr2、sxr2对应2664米水深处的温度、压力、盐度）；1台XR-420CT型温电导率记录仪（RBR有限公司生产，Matlab文件变量txr、sxr对应2789米水深处的温度、盐度）；以及1台Sea-Bird SBE37型温电导率记录仪，Matlab文件变量tsbe、ssbe对应2439米水深处的温度与盐度。
Matlab文件中的其余变量为对应温度、压力、盐度时间序列的Matlab序列日期数字向量：tvec对应TR-1050型传感器的时间序列，tvecxr对应所有XR-420型仪器的时间序列，tvecsbe对应SBE37型仪器的时间序列。
由于所有仪器均于2008年8月被重新部署，故无法进行航后校准。本次校准采用部署阶段于锚系仪器已知水深处获取的经校准的电导率-温度-深度（CTD, Conductivity, Temperature, Depth）剖面数据完成。
