Ballast Water Compliance Monitoring - Fluorometer Applications

The inadvertent introduction of invasive aquatic species to coastal waters when discharging ballast water has been known to cause both ecological and economic damage.  Accordingly, regulations are being established specifying low levels of live organisms and how to detect them when releasing ballast water. 

Treatment systems are being employed and the challenge of how to show compliance is under examination.  One of the methods for determining compliance that is receiving a lot of attention is active fluorescence which looks at the viability of the organisms in the ballast water.For many years Turner Designs has manufactured in situ Active Fluorometers used by oceanographers looking at phytoplankton photosynthetic efficiency.  Employing much of the same technology in their handheld package, Turner Designs now offers the Ballast-Check 2 Handheld PAM Fluorometer for quick indications of gross exceedance of the compliance standard.
