Experimental Pond Mesocosms (Pond or Limnocorral scale)

You may have heard about or seen our 5 year limnocorral study. We have done some great science in these mesocosms and are hoping to scale up to whole pond studies at the University of Mississippi Field Station in the future.

Experimental Stream Mesocosms (USDA-ARS and UMFS)

Another great set of mesocosms built by USDA-ARS and located at the UM Field Station. These experimental stream systems can either be flow-thru with source water from a spring or switched to recirculating. With approval from USDA these may be avaiable for student research projects. There are also many opportunities for students to design and build new mesocosm setups at different locations at the UMFS.

Sediment Core Incubations

We don't mean to brag...but we are pretty good at designing and building "trouble-free🫡😐🤣" continuous-flow sediment core incubation systems. These systems are useful for doing experiments to understand factors associated with dissolved gas and nutrient fluxes at the sediment water interface in aquatic ecosystems.

Membrane Inlet Mass Spectrometer (MIMS)

We currently have 2 MIMS on long-term loan from USDA-ARS. This instrument measures dissolved N2 , O2 and Ar with high precision and is a really useful tool for quantifying a variety of nitrogen cycling pathways.

Continuous-Flow Nutrient Autoanalyzer

I have primarily used a Lachat’s Quikchem 8500 Series 2 Flow Injection Analysis System for dissolved and total nutrient analysis. However this instrument is no longer supported by HACH. We are currently assessing alternative instruments (FIA-LAB, SEAL, etc) and will invest in a newer system in Fall of 2025. Send me a note if you have advice/opinions on different discrete and continuous-flow autoanalyzer instruments.

Total Organic Carbon

We also plan to invest in a Total Organic Carbon analyzer in Fall of 2025.
