The Carbon Cycle01:14

The Carbon Cycle

39.5K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

What are Biogeochemical Cycles?00:54

What are Biogeochemical Cycles?

34.1K
The most common elements in organic molecules, carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus, are only available in the ecosystem in limited amounts. Therefore, these nutrients must be recycled through both biotic and abiotic components of the ecosystem, in processes generally called biogeochemical cycles.

The Sulfur Cycle01:22

The Sulfur Cycle

46.1K
Sulfur, an important element in the chemical makeup of proteins, is recycled through the atmosphere and aquatic and terrestrial environments. Found in the atmosphere as sulfur dioxide (SO2), sulfur is released by decaying organisms, weathered rocks, geothermal vents, volcanos, and burning fossil fuels. It is deposited into the ecosystem, cycled through the biotic community, and either released back into the atmosphere as gas or deposited in marine sediment for long-term storage and eventual...

The Water Cycle01:00

The Water Cycle

24.8K
The Earth’s hydrosphere includes all of the areas where the storage and movement of water occurs. Since water is the basis of all living processes, the cycling of water is extremely important to ecosystem dynamics.

The Nitrogen Cycle01:49

The Nitrogen Cycle

54.0K
Nitrogen atoms, present in all proteins and DNA, are recycled between abiotic and biotic components of the ecosystem. However, the primary form of nitrogen on Earth is nitrogen gas, which cannot be used by most animals and plants. Thus, nitrogen gas must first be converted into a usable form by nitrogen-fixing bacteria before it can be cycled through other living organisms. The use of nitrogen-containing fertilizers and animal waste products in human agriculture has greatly influenced the...

Carbon-dioxide Fixation01:28

Carbon-dioxide Fixation

77
Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

Summary

Estimating carbon (C) dynamics is challenging due to disagreements in C-cycle process data. Combining satellite, atmospheric, and terrestrial/aquatic data can reconcile spatial mismatches and improve C-cycle science.

Area of Science:

  • Ecology
  • Earth Science
  • Environmental Science

Background:

  • Global carbon (C) dynamics understanding is a significant scientific challenge.
  • Expansion of carbon dioxide (CO2) observatories enables C-cycle process estimation but reveals data discrepancies.
  • Ecosystem-specific C retention varies widely, with grasslands retaining 2% and needleleaf forests 30% of fixed C.

Purpose of the Study:

  • To reconcile spatial mismatches in C-cycle process estimates across scales.
  • To identify potential carbon loss pathways using novel data integration.
  • To advance C-cycle science across the land-water interface.

Main Methods:

  • Utilizing newly available satellite and atmospheric data.
  • Combining independent datasets from terrestrial and aquatic environments.
  • Comparing ecosystem measurements with continental-scale estimates.

Main Results:

  • Continental US scale net ecosystem exchange (NEE) accounts for only 5% of photosynthetically fixed C.
  • Significant spatial mismatches exist, with the Southeast showing high gross primary productivity and the Midwest high NEE.
  • Ecosystem measurements reveal substantial variations in C retention across different biomes.

Conclusions:

  • Innovative integration of diverse datasets is crucial for accurate C-cycle assessments.
  • Addressing spatial mismatches is key to improving global carbon budget estimations.
  • Integrating land and water C-cycle science provides a more holistic understanding of global C dynamics.
