Download the Case Study Now! Learn how the King County Dept. of Natural Resources and Parks in Seattle, Washington conducts long-term marine monitoring to assess baseline conditions and trends in Central Puget Sound, especially nitrate. In this case study, Sea-Bird SUNA measurements from Puget Sound, corrected for bromide, match the accuracy of measurements made with traditional wet chemistry techniques to within ±0.0025 mgN/L. About Sea-Bird SUNA V2 The SUNA V2 is the ultimate solution for real-time nutrient monitoring. This sensor measures nitrate with industry leading accuracy and stability over a wide range of environmental conditions (including extremely turbid and high CDOM conditions), from blue-ocean nitraclines to storm runoff in rivers and streams. The SUNA V2 incorporates the proven MBARI-ISUS nitrate measurement technology, which is based on the absorption characteristics of nitrate in…

OTT Hydromet sensors play a critical role during Hurricane Harvey

OTT Hydromet sensors play a critical role during Hurricane Harvey

Case Study, Company News, Sensors, Water Level
  OTT Hydromet sensors for measuring water level in creeks and bayous, played a critical role during Hurricane Harvey. Hurricane Harvey, and the subsequent flooding, was an unprecedented and devastating event in eastern Texas. Harvey produced an average of 33.7 inches of rainfall over the 1,777 square miles of Harris County throughout a 4-day period which equates to 1 trillion gallons of water and is also 68% of the yearly annual rainfall. Of the 22 watersheds across Harris County, 13 established new record water levels during Harvey surpassing previous records by Tropical Storm Allison (2001), Tropical Claudette (1979) and the 2016 Tax Day flooding. The Harris County Flood Control District was first established in 1937 following two major floods within six years and started installing their Flood Warning System in…

Tech Note: Algae Measurements Using In Vivo Fluorescence

Sensors, Surface Water, Tech Note, Water Quality
Download the Free Technical Note: Algae Measurements Using In Vivo Fluorescence! Phytoplankton are microscopic, free-floating photosynthetic plants and bacteria that are commonly found in surface waters throughout the world. Aquatic scientists and water resource managers measure phytoplankton to gain a more in depth understanding on ecological dynamics, ecological health, nutrient status, and harmful algal bloom potential in aquatic systems. Submersible fluorescence sensors help to make this measurement easy, efficient, and economical by enabling real-time field estimates of phytoplankton biomass that can be directly correlated to quantitative laboratory measurements using standard methods.

Harris County Flood Warning System Case Study

Harris County Flood Warning System Case Study

Case Study, Sensors, Water Level
OTT RLS & CBS Water Level Sensors Making a Difference in Harris County. Download the Case Study! The Harris County Flood Control District in Texas was created in 1937 in response to the devastating floods that struck Downtown Houston and Harris County between 1929 and 1935. Currently, the District's boundaries include 3.7 million people in 34 jurisdictions one of which is the City of Houston. In just one year Harris County endured two massive rainfall events with totals of 8-16 inches in 3 to 12 hours. A total of 9800 homes were flooded and 9 persons died. The District is using its "Flood Warning System" (FWS) to measure rainfall and water level amounts in real-time, to provide up-to-date flood information.
