High precision temperature and salinity profiles are some of the most commonly collected and important data in many ocean science investigations. This work will develop a capability to solve a long standing problem in collecting such data at sea. The response times of temperature sensors and conductivity sensors are significantly different, so data mismatches commonly occur when these sensors are simultaneously mounted on a CTD profiler. A new calibration capability will investigate the dynamic response of commonly used thermometers and conductivity sensors. Results will be used to improve present techniques for removing salinity errors arising from the mismatch in sensor time constants. The facility will be useful in testing probes prior to deployment and for developing new sensor systems.

高精度的温度和盐度剖面是许多海洋科学研究中最常用和最重要的数据。这项工作将发展一种能力，以解决在海上收集此类数据的长期问题。温度传感器和电导率传感器的响应时间存在显著差异，因此当这些传感器同时安装在CTD分析器上时，通常会出现数据不匹配。新的校准能力将研究常用的温度计和电导率传感器的动态响应。结果将用于改进目前的技术，以消除由传感器时间常数不匹配引起的盐度误差。该设施将在部署前测试探针和开发新的传感器系统方面发挥作用。
