Coastal Marine Communities Intro

Question 1

Primary Production Measurement Metrics (2)

Answer 1

Gross Primary Production: Rate at which solar energy is captured in sugar molecules (Theoretical mostly)

Net Primary Production: the difference between the energy fixed and their respiration

Question 2

Non-direct measurement metrics (3)

Answer 2

The concentration of chlorophyll in the water is a proxy (mg Chl an m^-3)

Oxygen evolution in the water is a proxy (dissolved oxygen - O2 milligrams per litre (mg/L))

Photosynthetic bubbles make a sound, which can be recorded

Question 3

Primary Production: Nutrients

Answer 3

Primary production is largely controlled by abiotic factors

Nutrients such as Nitrogen, Phosphorus, Iron and Silicon

Question 4

Community Composition

Answer 4

The ecological community is the group of actually or potentially interacting species living in the same location
