Autonomous Plankton Sampler - provides Marine Biologists with a fully automated tool to collect plankton in the oceans, enabling analysis of plankton species distribution and abundance
Chelsea Technologies Group’s Autonomous Plankton Sampler provides Marine Biologists with a fully automated tool to collect plankton in the oceans, enabling analysis of plankton species distribution and abundance. Plankton sampling provides invaluable insights into numerous aspects of plankton dynamics and ecology including: climate change, biodiversity and biogeography, eutrophication, harmful algal blooms, fisheries investigations, plankton ecology, taxonomy, regime shifts and non-indigenous species.
The Plankton Samplier is ideally suited for use in undulating bodies such as the NuShuttle, to enable discrimination of zooplankton variability with depth. It is designed to operate autonomously, collecting zooplankton samples within a user programmable index advanced filter mesh, for post mission laboratory analysis. It can also be fitted to onboard flow-through systems such as FerryBox type systems.

How does it work
CTG’s Autonomous Plankton Sampler is loaded with two rolls of gauze on two separate spools. When the mechanism is activated, both gauze lengths are advanced 70mm via an electric motor. The frequency of each advance is programmed by the user via PC on either a time or flow-rate basis. One of the gauze lengths rests against a 100mm x 50mm aperture open to the flow of water, and it is here where the plankton is collected. On advance, the sampled plankton is sandwiched by the other gauze, and both gauze lengths and the sample are collected in the preserving tank.
CTG Autonomous Plankton Sampler is available either with internal battery or externally powered. Both silk and nylon gauzes are available. A suitable flow meter is available as well as a flow-through housing.
