Oceanographic profile water temperature and salinity data collected from the Rogue River Mooring off the coast of Oregon from 2000-05-18 to 2000-09-16 (NCEI Accession 0136938)

A single mooring measuring temperature, salinity, and velocity was deployed on the 73 m isobath off the Oregon coast. The mooring was located at 42° 26.49' N, 124° 34.47' W, 11 km off Gold Beach, OR and was in the water from May 2000 to October 2004. The currents were sampled using an upward-looking RD Instruments 300 kHz broadband ADCP instrument burst-sampling 40 1-s pings every 15 minutes in 4-m depth bins. The taut-wire mooring had Seabird SBE-37IM MicroCAT temperature, conductivity, and pressure instruments at 20, 36, and 66 m sampling every 5 minutes and Seabird SBE-39 temperature only sensors at 26, 42, 50, and 58 m also sampling every 5 minutes. The MicroCATs represent the mid-depth and as close to the surface and bottom as possible given the mooring design. The 1.8 m (45) steel top sphere was moored at 17 m to avoid mooring motion induced by the extremely large (>12 m) surface waves which sometimes occur during winter storms off the Oregon coast. At tidal frequencies, typical blow-down at the top MicroCAT was less than 2 m with pitch and roll at the ADCP of less than 6 degrees. The worst-case mooring performance was during the severe winter storms of November and December 2002, when the blow-down was about 7 m and the pitch briefly hit 25 degrees. The mooring was recovered and redeployed every six months for four years. The early data revealed the need to sample closer to the surface than the original mooring design allowed. To facilitate this, a light-weight pennant consisting of a 30 cm plastic float on a thin spectra line was flown off the top of the 1.8 m sphere. A Star-Oddi Starmon mini temperature pod was taped to the line to sample temperature every 5 minutes at 6 m depth. This simple system worked surprisingly well starting with the fall 2001 deployment. Funding was provided by the NOAA Coastal Ocean Program.

本数据集依托一套部署于俄勒冈海岸外73米等深线处的单锚系观测系统，用于采集温度、盐度与流速数据。该锚系位于北纬42°26.49'、西经124°34.47'，距离俄勒冈州戈德比奇海岸11公里，于2000年5月至2004年10月间持续布放于海中。流速数据由一台朝上安装的RD仪器公司（RD Instruments）300kHz宽带声学多普勒流速剖面仪（Acoustic Doppler Current Profiler, ADCP）采集，该设备采用突发采样模式：每15分钟对4米深度层内采集40次时长为1秒的声脉冲数据。该紧绳锚系搭载了海鸟（Seabird）SBE-37IM MicroCAT温盐压传感器，分别布放于20米、36米与66米水深，每5分钟完成一次数据采集；同时在26米、42米、50米及58米水深布放了海鸟SBE-39型单温度传感器，同样以5分钟为采样间隔。从锚系设计布局来看，MicroCAT传感器被设置在中层水深以及尽可能贴近表层与底层的位置。锚系顶部搭载了一个1.8米（标注45）的钢制浮球，布放于17米水深处，用于规避俄勒冈海岸冬季风暴期间偶尔出现的超大型（浪高>12米）表层海浪引发的锚系运动。在潮汐频段内，顶部MicroCAT传感器的典型沉降量小于2米，声学多普勒流速剖面仪的俯仰与横摇角度均小于6度。锚系表现最差的时段为2002年11月至12月的强冬季风暴期间，此时沉降量约为7米，俯仰角短暂达到25度。四年间，该锚系每半年就会被回收并重新部署一次。早期观测数据显示，原有锚系设计无法满足贴近表层采样的需求。为解决这一问题，研发人员在1.8米钢制浮球顶部加装了一套轻型浮标系统：由一个30厘米塑料浮球与一根细Spectra缆绳（spectra line）组成。将Star-Oddi Starmon迷你型温度采集舱绑定于该缆绳上，可在6米水深处以5分钟为间隔采集温度数据。自2001年秋季部署以来，这套简易装置的运行效果远超预期。本项目由美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）海岸海洋项目资助。
