What is in the air we breathe? 

In the air we breathe, there are gases present such as oxygen, nitrogen, carbon dioxide, water vapor as well as many other gases in much smaller quantities – nitrogen oxides, sulfur oxides and formaldehyde just to name a few. Besides these gases, there is something else in the air we breathe, tiny microscopic particles called aerosols. Not just the aerosol that comes from spray cans that you may be familiar with but I am talking about any liquid or solid particle floating in the air, which is the definition of an aerosol – a solid or liquid particle suspended in air. Atmospheric aerosols come from many sources.  In my seminar, I will talk about aerosols and the air we all breath.  From mineral dust to sea spray to soot, these particles impact atmospheric chemistry, the Earth’s climate and human health in ways we are just starting to understand.

Observing and understanding variability in phytoplankton morphology

Phytoplankton in the ocean exhibit tremendous variation in cell size, form, and coloniality. This morphological variation may help sustain species diversity by providing multiple avenues for species to achieve equivalent fitness, and may also impact ecosystem function by influencing the trophic transfer and transport of carbon from oceanic primary production. However, we still know relatively little about the costs and benefits of phytoplankton colony formation, and what controls temporal variations in the occurrence of different phytoplankton sizes and shapes. Here, using underwater microscope image data from the Scripps Plankton Camera System
