FlowCam Part of GlobalHAB Symposium Intercomparison Study

GlobalHAB is an international scientific program on harmful algal blooms (HABs) that fosters collaborative research efforts aimed at understanding and predicting HAB events in aquatic ecosystems while also providing scientific data to help manage and mitigate their impacts. As part of their efforts to provide a structure for planning and coordinating international activities related to HAB research, the program recently facilitated the GlobalHAB Symposium on Automated Observations of Plankton. FlowCam team members, Savannah Judge and Nicole Gill, traveled to the Kristineberg Marine Research Station in Fiskebäckskil, Sweden to participate. The center’s boat basin is pictured below.

Using FlowCam Macro to Evaluate Spatial Distribution of the Copepod Calanus finmarchicus in the Fram Strait

Carbon sequestration refers to the capture, removal, and storage of carbon dioxide (CO2) from the atmosphere. It is a key process in stabilizing carbon in solid and dissolved forms that doesn't contribute to atmospheric warming and climate change. There are biological and geological mechanisms of carbon sequestration with oceans absorbing approximately 25% of anthropogenically produced CO2 annually.

Optimizing Distance to Nearest Neighbor to Improve Particle Capture

Utilizing proper capture settings during image acquisition is crucial to obtaining accurate concentration and sizing data with FlowCam. Distance to nearest neighbor (DNN) is an important capture setting that specifies the distance (in µm) required between two particles for them to be imaged separately. Properly optimizing DNN ensures that only one complete particle is captured per image.

Purdue University Uses FlowCam Nano to Study Atmospheric Aerosols' Effect on Climate Change

The Alexander Laskin Research Group at Purdue University is a "multi-disciplinary experimental group with research interests in the areas of Analytical and Physical Chemistry of airborne and aquatic environmental particles, driven by the overarching goals of understanding their impact on the environmental chemistry, the air pollution, and the Earth’s climate."

The environmental particles studied by the Alex Laskin group can have natural and anthropogenic sources including oceans, deserts, volcanoes, transportation emissions, aviation, fire retardants, explosion disasters, and even household cooking. These particles often have multiphase chemistry, meaning they can change shape, size, and chemical composition. Particles below 2.5 µm are considered respirable and are able to enter the lungs, bloodstream, and brain.

Obtaining Accurate Concentration Data with FlowCam

FlowCam 8000 series instruments provide count and concentration data for a wide variety of fluid samples. Relative counts can be compared reliably among different samples, while concentrations provide particles/mL values based on the actual fluid volume imaged by the instrument. By understanding and considering the various factors that can affect reported concentrations, FlowCam users can ensure they are obtaining accurate concentration data.
