|Here I am filtering the chlorophyll samples!|
The samples can take longer to filter if there are jellies present (as noted above).
After bringing the samples back to Valdosta with my mentor Dr. James Nienow, I worked with other researchers in the lab (Anastasia Nienow & Courtney Bryller) to acid wash the samples. The acid washing involved using nitric acid and potassium dichromate to clean our samples. The nitric acid and potassium dichromate oxidizes the solutions and washes away organic matter. This leaves the silica remains of the different diatoms for analyzing. Our next step will be to observe the different amounts, associations, and structures of the phytoplankton!
