Current Technology Evaluation
ACT has initiated a Performance Verification of in situ salinity sensors and all results will be made available to the public in summary reports in January 2009. As part of our service to the coastal community, ACT Partner Institutions andStakeholder Council have chosen the performance verification of commercially available, in situconductivity/temperature sensors that provide a derived measurement of salinity. There are a number ofchallenges in assessing salinity in coastal aquatic systems that point to the value of sustained insitu observations. High spatial horizontal variability is typical of many coastal, estuarine andfresh water systems, as are strong depth gradients. High temporal variability in naturalbackground concentrations are typical of many locations, often in response to short-term forcing(e.g., vertical mixing) or input events (e.g., runoff, river discharge).
This ACT Technology Evaluation is examming individual sensor performance both inthe laboratory and across different field conditions in moored and vertically profiledapplications. We will focus specifically on commonly used inductive, conductive, and electrodebased conductivity sensors with measuring ranges from 0 - 100 mS/cm. |
