The Aquatic Autosampler is designed to collect discrete water samples
of a known volume autonomously, concentrate particles contained within
those samples onto filter disks, and automate application of
preservatives, DNA (or other molecular probes) to enable identification
and quantification of particular species of micro organisms so captured.
Preliminary tests of the prototype built in 1998 have shown that cells
(cultured and from natural samples) can be collected and be distributed
uniformly on different types of filters, whole cells can be preserved and
stored for later analysis, species-specific DNA probes can be applied to
label target species (whole cells), and cells can be homogenized as well
(this is the input material for real-time detection). These preliminary
tests validate the most fundamental concepts on which the Aquatic Autosampler
A major milestone for this project in 2000 is to deploy an Aquatic Autosampler
mooring by the summer.
