Getting STOQ’d about HOTs Graphs

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.
