Time-series oceanographic data from the Monterey Canyon, CA October 2015, March 2017, CCE15M1A08aqd

Time-series oceanographic data from the Monterey Canyon, CA October 2015 - March 2017 - CCE15M1A08aqd. Time-series data of water depth, velocity, turbidity, and temperature were acquired between 5 October 2015 and 21 March 2017 within the Monterey Canyon off of Monterey, CA, USA.

In order to better understand the triggering, progression and evolution of turbidity currents in Monterey Submarine Canyon, an experiment was designed to directly measure velocity, suspended sediment and physical water properties (temperature, salinity and density) along the canyon axis during an 18-month period.

Three moorings in the upper canyon (MS1, MS2, MS3) containing oceanographic instruments and Anderson- type sediment traps were deployed during three consecutive six-month periods (A: October 2015 - April 2016; B: April - October 2016; C: October 2016 - March 2017). In addition, a bottom platform to the South of the canyon head (MS0) housed instrumentation to measure currents and waves on the adjacent shelf. The mooring diagram image files are a generalized representation of the deployed instrumentation at each site, and are included as a visual aid for understanding the sampling environment. A text file of the specific sensors listing the parameters measured is also included.

加利福尼亚州蒙特雷峡谷2015年10月至2017年3月的时间序列海洋学数据 - CCE15M1A08aqd。该数据集记录了2015年10月5日至2017年3月21日间，位于美国加利福尼亚州蒙特雷市附近的蒙特雷峡谷内水深、流速、浊度和温度的时间序列数据。为了更好地理解蒙特雷海底峡谷中浊流触发、发展和演变的机制，设计了一项实验，在为期18个月的期间内，直接测量峡谷轴线上的流速、悬浮沉积物以及物理水特性（温度、盐度和密度）。在峡谷上部部署了三个浮标（MS1、MS2、MS3），每个浮标装有海洋学仪器和安德森型沉积物收集器，并在连续的三个六个月期间进行部署（A：2015年10月至2016年4月；B：2016年4月至10月；C：2016年10月至2017年3月）。此外，在峡谷头部以南的位置设置了一个底部平台（MS0），用于测量相邻浅滩上的流速和波浪。部署的仪器示意图文件是对每个站点部署的仪器的概括性表示，并作为理解采样环境的视觉辅助工具。还包括一个文本文件，其中列出了具体传感器及其测量的参数。
