Water Sampler
The Water Sampler solves the problems surrounding manual water sampling by taking automated water samples at predetermined times using a highly flexible timetable via a programming interface. A selectable purge function eliminates contamination by flushing the system between samples. Samples, pumped into separate bags piped into the connectors at the top of the sampler, can be retrieved post-deployment for analysis.
The Water Sampler was originally designed for use with a continuous plankton recorder (CPR), where aquatic biologists are interested in species of organisms. With respect to phytoplankton, chlorophyll fluorescence may give an indication of total phytoplankton abundance but gives no indication of species present. This may be important where some species are toxic.
The water sampler can be programmed to take samples that are coincident with fluorescence measurement by separate instruments to ground truth these measurements. As such, a key feature is the compact design of the water sampler allowing it to be fitted to a CPR.
Having been successfully deployed and further enhanced, it offers capability for remote control sampling through an Iridium satellite interface,
allowing the user to activate sampling form their desk via PC software anywhere around the world. This provides a feature that could be appealing to any user
needing to sample a remote environment without the need for regular on-site attendance. In this configuration the water sampler can be used to capture
water contaminants.
