This dataset contains shipboard Underway conductivity, temperature, and depth (UCDT) measurements taken during the Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) field campaign.

2014年4月1日 · The Oceanscience underway CTD (UCTD) is a recently developed system for obtaining deep vertical profile CTD data from a moving ship (Rudnick and Klinke 2007). We recently used the UCTD on two hydrographic survey cruises as a means to increase the spatial resolution of the survey without having to perform additional time-consuming CTD casts.

2014年3月31日 · The UCTD is a rapidly profiling sensor package lacking a pump that relies on instrument motion to produce flow through the conductivity cell. With variable instrument descent rate, the flow...

2007年11月1日 · The purpose of this paper is to present the design, construction, operation, and example data of the UCTD. A functional description of the UCTD is presented in section 2. Practical use of the UCTD is described in section 3. A recent successful deployment of UCTD to do science (as opposed to engineering tests) is presented in section 4.

An underway-CTD (uCTD) is a towed profiling CTD instrument providing salinity and temperature observations from the surface to 500m while underway at up to 12 kts.

An UCTD is a towed CTD instrument providing conductivity, salinity and temperature depth profile observations while underway at up to 20kts. 771 UCTD casts occurred during the Knorr and …

Abstract: The Underway Conductivity-Temperature-Depth (UCTDtrade) instrument allows the collection of high-quality temperature and conductivity profiles from moving vessels in a cost-effective and environmentally safe manner. From these profiles it is possible to derive other data, such as salinity and sound speed.

The Oceanscience underway CTD (UCTD) is a re-cently developed system for obtaining deep vertical profile CTD data from a moving ship (Rudnick and Klinke 2007). We recently used the UCTD on two hy-drographic survey cruises as a means to increase the spatial resolution of the survey without having to perform additional time-consuming CTD casts.

近年来国内外发展的UCTD作为新型船载海洋调查设备，整机占用空间小，其探头可在船舶航行时通过专用甲板设备投放后收回，在不耗费航时的情况下能获取连续小尺度和高精度的温盐深剖面数据，与传统的调查手段相比可显著地提高调查的效率 [1]。

本文研究了走航式温盐深剖面测量仪 (UCTD)下降速度模型,根据基本参数计算了UCTD的下降速度.理论计算和海上试验表明,UCTD下降速度远大于传统剖面测量CTD,在下放过程中,UCTD下降速度呈现波动减小的现象,给数据处理工作带来新的挑战.本文在借鉴传统CTD数据处理 ...
