Alba daily is in charge of taking surface samples and on the depth which locates the maximum of chlorophyll. This peak indicates that is where there is greater abundance of microscopic organisms able to do chlorophyll function. A few drops of lugol (containing iodine and acetic acid) until the sample acquires the color of whiskey. From these samples, the microscopic species would be identified and counted. This work will be done in the INTECMAR.

The law of the funnel: Part of the work of counting is done with this device called Flow Cam has a lens such as the microscopes. The 20 ml sample that Alba gets into the funnel, flows through a plaque which is centered on the lens. In this way, pictures are taken on the species and simultaneously count per sizes the particles that pass through the lens.

Screenshot: Counting of a sample as shown on the screen after passing the 20 milliliters of sample through the lens. All this information is saved on the computer.
