Questions and Answers
What is the main source of CO2 in estuaries and how does it enter the system?
The main source of CO2 in estuaries is microbial respiration of organic carbon (OC) from primary production. CO2 enters the estuary system through rivers, wetlands, and resuspension of sediment.
What are some of the factors that can change primary production mechanisms and nutrient delivery in estuaries?
Future changes in precipitation, freshwater input, and stratification can change primary production mechanisms and nutrient delivery in estuaries.
What are 'blue carbon sinks' and how do they compare to rainforests in terms of carbon storage?
'Blue carbon sinks' are coastal wetlands that store carbon in sediment and vegetation. They can store carbon for millennia, as opposed to decades in tropical rainforests. They also take in CO2 at a rate 55 times faster than tropical rainforests.
