Team Carbon Sinks will develop an
effective, economically feasible, and
environmentally friendly method for
sequestration of carbon in dead trees.

Background

Carbon Cycle
5
Intergovernmental Panel on
Climate Change
• Created by the United Nations
• Published Fourth Assessment Report in
Spring 2007
6
Statistics from 4th Assessment
• Increase in atmospheric CO2
concentrations over the past 50 years is
the result of human activity
• By 2100, temperatures will rise between
2-11.5 degrees F and sea levels will rise
88 cm without changes in human
activity
7
Kyoto Protocol
• Part of the United Nations Framework
Convention on Climate Change
(UNFCCC)
• Goal is to reduce greenhouse gas
emissions
8
Reducing Greenhouse Gases
• Alternative fuels
• Carbon Sequestration
• Carbon Sinks
9
Introduction to Project
• Lack of research about sequestering
carbon naturally stored in wood
• Used Dr. Zeng’s research to explore how
to maximize forests’ carbon capacity
10
Aim of Project
• Develop a process
that effectively slows
the natural
decomposition of
wood by depriving it of
oxygen
• Applicable throughout
North Atlantic Forests
11
Basic Assumptions
• Sequestered carbon will have monetary
value in the future
• Companies or private land owners
should be easily able to reproduce the
process
12
Hypothesis
• By placing biomass in an anaerobic
environment, it is possible to slow the
decay and effectively create a carbon
sink
13
Methodology
• 76 Loblolly pine disks, 10
cm thick:
– 15 for submergence in water
– Bury the rest in 15 columns,
one disc at:
– 10, 40, and 80 cm
– Control on surface
• Measurements every 4
months
• Remove 3 columns, 3 discs
from water.
14
Water submersion
• Oyster cage will hold
discs
• Will keep discs close
to, but not in contact,
with the bottom of the
pond
• Regular analysis of
water composition
more necessary than
soil analysis.
15
Measurement
• Soil, water composition
• Measures of decay
• Mass
• Density
• Carbon content
• These factors will be re-examined upon
removal – discs will not be returned.

Eastern Shore
• Eastern Shore representative of
Northeast Coast
– Previously farmed land
– Most prevalent in Atlantic Coast area
• Facilitates future use of our method
18
Current Status
• What we have already done:
– Found site
– Obtained wood to be buried/submerged
– Contact information for soil lab
– Developed experimental methodology
19
Future Plans
• Begin actual experiment within the
month
– Bury and submerge wood
– Collect initial soil samples
• Contact soil labs, compare services
