Abstract: A ballast water monitoring device and a method for detecting live phytoplankton are disclosed. The device comprises a chamber for receiving a sample, at least one light source to emit light towards the sample, a light detector to receive light from the sample and generate a light signal, and a controller. The controller is configured to control the at least one light source to emit a single pulse of light, calculate the variable fluorescence [Fv] of the sample in response to the pulse of light, at time intervals less than the duration of the pulse of light, compare the calculated variable fluorescence to a predetermined reference limit, and perform an action if the calculated variable fluorescence is greater than the predetermined reference limit.

Abstract: A monitoring device 2 for detecting live phytoplankton in ballast water 1 calculates the variable fluorescence of the phytoplankton. This is achieved by use of a controller, configured to illuminate the chamber containing the sample with a single pulse of light, from at least one light source 50, and detecting the response of the sample at time intervals less than the duration of the pulse of light with a light detector 40. This calculated variable fluorescence is then compared to a predetermined limit and, if the variable fluorescence is greater, an action is performed. This performed action optionally comprises eliminating the algae. Optionally, it is possible to use different colours of light to detect different species of phytoplankton and as detection of the phytoplankton can occur in the dark, it is not necessary to pulse the light source.
