How do tiny ocean critters affect the global carbon cycle?

Front

What is the significance of the bacterial community in the ocean?

Back

It determines the types of dissolved organic carbon present.

Front

Where is refractory dissolved organic carbon found?

Back

Deep ocean.

Front

What is a release of carbon dioxide from the land to the atmosphere?

Back

Carbon emissions.

Front

What factors should be investigated to understand how climate change affects oceanic bacteria processing dissolved organic carbon?

Back

Temperature effects, salinity changes, acidity levels, and currents.

Front

What is labile dissolved organic carbon?

Back

Carbon at the surface of the ocean that cycles back to the atmosphere in seconds, minutes, or days.

Front

What role do tiny ocean critters play in the carbon cycle?

Back

They contribute to the breakdown and transformation of organic matter, influencing carbon storage and release.

Front

Define dissolved organic carbon (DOC).

Back

Organic molecules dissolved in water, which can be utilized by marine organisms.

Front

What is the difference between labile and refractory dissolved organic carbon?

Back

Labile DOC is quickly utilized by organisms, while refractory DOC is more resistant to degradation.

Front

How does ocean temperature affect bacterial activity?

Back

Higher temperatures can increase metabolic rates of bacteria, affecting carbon processing.

Front

What is the impact of ocean acidity on carbon cycling?

Back

Increased acidity can affect the growth and function of marine organisms, altering carbon dynamics.
