  1. Getting STOQ’d about HOTs Graphs

  2. 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 Image: SEM of Prochlorococcus MIT9215, pseudocolored Taken by: Anne Thompson

  3. 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. Photo: Paul Lethaby

  4. 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. • http://www.youtube.com/watch?feature=player_embedded&v=0d3KHbGqSMA
