Prochlorococcus• This is a photosynthesizing marine microbe –
it uses light and CO2 to produce glucose and oxygen.
• 50% of the oxygen in the atmosphere is produced by these organisms!
• It is typically found in the photic zone of the water column where light can penetrate – This happens from surface – appx. 200m deep

How We Observe: Technologies
• CTD – The CTD is lowered into the water. It takes
measurements continuously as it moves vertically through the water column.
• Rosette – This device also moves vertically through the
column. At different points in the water column, containers are programmed to collect water at specific depths for further analysis.

How We Observe: Technologies
• Autonomous Underwater Vehicle (AUV)– These vehicles are programmed to take
continuous data as they move up and down in the water column.
– They are also programmed to collect water at different points in the water column.

• Discussion points – Researching Ocean properties• Temperature, Salinity, Pressure, Light
– Way science is actually presented • Combination of variables
