Question 1

Name 3 examples of S gases that are released from the ocean and where their possible sources may be

Question 2 A

Why do POC flux decrease with depth, include processes that are biogeochemical as well (few lines please)

Question 2B Determine POC flux @ 100m & @ 500m, if 30% of POC flux is lost between 100 & 500m and is changed to DOC & leftover has changed to carbon dioxide, Determine the noticeable increase in DOC & CO2 fluxes at those depths

Question 2C

What happens to carbon dioxide at these particular depths

Question 2D

Say at 2500m this is the bottom depth and the sediments are in equilibrium state for C, & POC is only source to sediments, what is the C flux out of the sediments?
