Tools - Plankton Planet

We are developing a new generation of low-cost, user-friendly, and engaging instruments that are, above all, scientific and standardized. These tools enable sea citizens to both explore and measure ocean life, transforming them into “planktonauts.”

Planktonauts can be recreational sailors, offshore racing professionals, fishermen, or cargo ship crews. The affordable price of the instruments developed by Plankton Planet allows for equipping hundreds, if not thousands, of boats. The main challenge lies in retaining planktonauts and ensuring a long-term, consistent global measurement of the ocean.

In 2015-2016, we validated the concept by recruiting 20 crews of planktonauts who collected plankton samples from over 250 sites across the world’s oceans. Subsequent genetic analyses confirmed the reliability of the protocol.

Discover the Plankton Planet Project Pilot

Today, we are developing the “Plankto-Kit,” a kind of mini onboard laboratory that includes all the interconnected elements needed for a comprehensive eco/morpho/genetic measurement of plankton. In particular, we have created the PlanktoScope, an automated microscope that not only allows for observing plankton but also captures real-time images to quantify the biodiversity present at a given site. This measurement, conducted on fresh plankton, is unique and complementary to genetic analyses performed on the same preserved samples aboard.

Our tools

The Lamprey

This product is a self-contained mobile filtration unit that uses a PPSU MF 3pro magnetic filter holder (47 mm filter diameter), manufactured by Rocker® (ref: MF3Pro).

It facilitates liquid environment filtration both in the field and in the laboratory. The various components provide scientists with an ergonomic workspace for sample processing, ensuring compatibility with genetic samples.

The unit is powered by a rechargeable and removable lithium-ion battery and features a peristaltic pump.

The PlanktoScope

The PlanktoScope V.2.6 is a continuous-flow microscope designed by FairScope for high-precision imaging of suspended particles. It excels at capturing detailed images of plankton up to 300 µm, enabling in-depth plankton studies.

This cost-effective device, equipped with high-resolution imaging capabilities, is an ideal asset for research laboratories focused on aquatic ecosystems, striking a balance between budget constraints and the need for advanced microscopy.

The Curiosity microscope

The Curiosity microscope is a modular device developed as part of Plankton Planet, designed for microbiome exploration.

With its original design and robust build, it captures details of the invisible world and allows for full manual exploration of a wide variety of samples (plants, animals, soils, etc.).

Featuring high-resolution (4K) imaging and an ultra-portable format, it is a rare and ideal tool for field observation, classroom use, or laboratory bench work. It strikes a balance between affordability and the need for high-quality, user-friendly microscopy.

The Nets

Plankton nets are ancient inventions. Materials such as silk and later nylon have been used to create more resistant and durable “socks.” More precise weaving techniques have enabled nets to selectively collect organisms based on their size.

This selective capability has allowed scientists to study the vertical and horizontal distribution of plankton and its interactions with other marine organisms.

Today, plankton nets are standard tools used in oceanographic research and environmental monitoring. They are employed in a wide range of marine environments, from coastal waters to the deep ocean. The data collected with these nets are essential for understanding marine ecology, biogeochemical cycles, and the impact of climate change on ocean ecosystems.

Configuration for the deployment of the Bougainville mission.

First, the PAR sensor (1) measures sunlight, and the CTD sensor (2) measures the conductivity, temperature, and depth of the ocean. Next, plankton is collected from the ocean using two nets (3) (4) or using the HSN net (5), which allows collection without reducing the boat’s speed (between 4 and 8 knots). Finally, measurements and data recording are carried out on board the boat (6).
