Field Microprofiling System in Yellowstone

Enabling Biogeochemistry Research

The Winning Formula

Ole Pedersen, co-founder of Unisense and expert microsensor user, has applied microsensors in seagrass beds in the Caribbean Sea, rice paddies in the Philippines, and peat swamps in Australia. In this article, Ole shares "The Winning Formula" for conducting microsensor experiments. Read more...

Sediment Profiling Analysis

Learn how to use SensorTrace Profiling to quantify the consumption rate of oxygen as well as the oxygen exchange rate across the water - sediment interface, from a high resolution oxygen profile, measured with a MicroProfiling System. Read more...

Effects of global warming in Arctic lake

A research group from University of Alberta used the Field Microprofiling System and microsensors for O₂, pH and Redox to quantify the effects of increased glacial runoff on sediment processes in Lake Hazen. Their results were in Nature Scientific Reports. Read more...

Photosynthetic biofilms

With sensor tip sizes down to 3 µm, Unisense microsensors make it possible to perform measurements at high spatial resolution. An example is this investigation of the dynamics within the layers of microbial mats. Read more...

Measuring in Rhizosphere

In this study, microsensors were used to demonstrate how sulfide oxidation influenced the sulfide concentration at the root of a macrophyte. Read more...

Oxygen profiles in salty crust

Dr. Don Canfield and Ketil Sørensen, University of Southern Denmark used needle sensors to examine the vertical distribution of phototrophic and non-phototrophic microorganisms in 2 saltern evaporation ponds with salinities of 156 and 206 g l^-1. Read more...
