1. Data Set Overview

1.1 Data Set Identification

BOREAS TGB-03 CH4 and CO2 Chamber Flux Data over NSA Upland Sites

1.2 Data Set Introduction

The Trace Gas Biogeochemistry (TGB)-03 team took chamber flux measurements at upland sites

in the BOReal Ecosystem Atmosphere Study (BOREAS) Northern Study Area (NSA) from late May to

early September 1994 and early June to late October 1996.

1.3 Objective/Purpose

The objectives of these measurements were:

• To examine the trace gas exchange between the atmosphere and the boreal upland soils.

• To identify environmental controls on CH4 and CO2 flux and the spatial and temporal

variability associated with those controls in order to improve the process models that describe

exchanges of trace gases between the boreal ecosystem and the atmosphere.

Page 1
1.4 Summary of Parameters

In the 1994 sampling season, CI-h and CO2 chamber flux measurements were taken from 11 sites.

These sites were designated as 1989 burn moss, 1989 burn spruce, palsa moss, palsa birch, Gillam

aspen, Gillam pine, Gillam spruce, Young Jack Pine (YJP) wet, YJP dry, Old Black Spruce (OBS)

aspen, OBS spruce.

In the 1996 sampling season, CI-h and CO2 chamber fluxes were measured at YJP wet, YJP dry,

OBS aspen, OBS spruce, Old Jack Pine (OJP) moss, OJP aspen, and OJP pine (note OJP sites

sampled by Patrick Crill in 1994).

1.5 Discussion

In 1994, CH4 and CO2 chamber flux measurements were taken at the 11 sites within the NSA to

determine the soil surface exchange rate of CH4 and CO2 at these locations. The locations represent

both a hydraulic and disturbance gradient. The sampling collars were installed in the spring of 1994 by

the McGill researchers (TGB-03), and measurements of CH4 and CO2 flux were made during and

between the 1994 and 1996 Intensive Field Campaigns (IFCs).

3. Theory of Measurements

Chamber fluxes measure the changes in mixing ratio of trace gases (CH4 and CO2) in a closed

headspace over a period of time. This headspace is isolated from the atmosphere; therefore, the

exchange of material between the covered soil and the headspace can be quantified.

4. Equipment

4.1 Sensor/Instrument Description

The CH4 and CO2 flux measurements were taken with PVC collars (26 cm in diameter) and

chambers made from polycarbonate bottles (26 cm in diameter; 40 cm tall; area of exposure 0.053 m2;

Moore and Roulet, 1991). Bottles were covered with aluminum foil to reduce heating. The neck of

each bottle was sealed with a rubber stopper that contained a glass tube with a rubber septum with a

1-m length of Tygon tubing attached to the top to minimize disturbance. Syringes were made of

polypropylene.

CH4 and CO2 were quantified with a Shimadzu 14A Gas Chromatograph (GC) equipped with a

flame ionization detector (FID) for CH4 and thermal conductivity Detector (TCD) for CO2. A

HayeSepQ column was used, the GC temperature was set at 40 °C, and ultra-pure (99.999%) N2 was

used as the carrier gas flowing at 30 mL/min. The detectors were operated at 125 °C. Analog signals

(0-1 V) from the detectors were digitized at 10 Hz with a Hewlett Packard (HI:') 35000D A/D board

and quantified and logged using HP ChemStation software.

Chamber fluxes were accomplished with aluminum chambers manufactured at the University of

New Hampshire (UNH) and designed by Patrick Crill.

4.1.1 Collection Environment

The chamber fluxes were collected under ambient environmental conditions.

4.1.2 Source/Platform

Ground.

4.1.3 Source/Platform Mission Objectives

4.1.4 Key Variables

4.1.5 Principles of Operation

The Shimadzu GC-14A is equipped with a FID and a TCD. The FID is used to detect CH4; the

TCD is used to detect CO2. The FID uses a hydrogen flame in an air atmosphere to burn components

as they exit the column. In the flame, carbon-carbon bonds are fragmented so that various organic ions

and free electrons exist. Application of a voltage across a collector electrode over the flame causes an

ion current to flow that is amplified and then measured as the output signal. The TCD detects CO2 by

passing a sample in a helium carrier gas past metallic filaments with current flowing through them. The

sample components with lower thermal conductivity than the helium carrier gas raise the filament

temperature when they pass through. The signal output from the TCD is a measurement of the change

in filament resistance caused by the temperature rise. The signal output from both the FID and TCD is

for a data processor, integrator, recorder, or computer (Instruction Manual: GC- 14A; Shimadzu

Corporation, Kyoto, Japan).

4.2 Calibration

4.2.1 Specifications

Analyses were conducted with a Shimadzu GC with a FID (FID-GC) using a Porapak Q column.

Nitrogen was used as the carrier gas, and CH4 standards of 2.349 ppmv were used to calibrate.

Precision of the analysis (standard deviation as percent of the mean of 10-15 daily repetitions of the

standard) was less than 1% of the standards. Fluxes between 0.1 and -0.1 mg/mZ/d were not

detectable.

Signal peaks from the detectors were quantified with working standards calibrated against

Canadian Atmospheric Environment Services (AES) certified primary standards acquired by the

BOREAS project and a C02/CH4 standard of Niwot Ridge air prepared by the National Oceanic and

Atmospheric Administration (NOAA) Climate Monitoring and Diagnostics Laboratory (CMDL).

Uncertainty in the standards' analyses on a given day ranged from 0.1 to 0.2%.

4.2.1.1 Tolerance

The sensitivity of the TCD is approximately 6,000 mV mL/mg. The FID's maximum sensitivity is

3 x 10-12 g/s for diphenyl.

4.2.2 Frequency of Calibration

The instrument is calibrated on a daily basis. Standards are run generally before and after samples

on a given day of analysis.

4.2.3 Other Calibration Information

None given.

5. Data Acquisition Methods

A total of 66 PVC collars were placed along the moisture and disturbance gradients in the NSA and

sampled in 1994. CH4 and CO2 were sampled at each of the collars once a week from early May

through mid-September 1994 using a static chamber technique (Crill et al., 1988). Water was added to

the groove in each collar before inserting the chamber in order to make an airtight seal. Air samples

were obtained from each chamber by inserting a polypropylene syringe into the Tygon tubing equipped

with a three-way stopcock and pumping the piston four or five times to mix air in the chamber before a

60-mL sample was drawn. A 10-mL sample was taken from the 60-mL syringe using the three-way

stopcock. Four 10-mL samples were taken at 5-minute intervals over a 20-minute period. Samples

were returned to a laboratory in Thompson and analyzed for CH4 and CO2 within 4-6 hours of

collection.

9.1 Formulae

9. Data Manipulations

9.1.1 Derivation Techniques and Algorithms

Rf = Cstd /Astd

Cs = Rf * A s

Rf = Response factor

Astd = Standard peak area

Cstd = Concentration of the standard

Cs = Concentration of the sample

As = Peak area of sample

CH4 concentrations were calculated from the average of 10 peak areas of known CH4 standards. The

response factor was calculated as the concentration of the known standard divided by the average of 10

standard peak areas. The peak area of the unknown sample was multiplied by the response factor.

The flux calculations were made by fitting a regression curve to the time series of CH4

concentrations. The flux rate of a gas is calculated using the following equation:

Flux(mg/m2/d) = ppmv/min * (P/R*g/mol of the gas) * (1/T)*Vc/Ac

• (1000mg/g* 1440min/d)

where: P = pressure in atmospheres

R = 8.2054 x 10 5 m3 atm/mol/K

gases: CH4 = 16 g/mol

T = degrees K of the chamber

Vc = chamber volume in m3

Ac = chamber area in m2

Vc=((E/100 x 0.047 x 1000) + Vt

Vc = volume of the chamber

Vt = volume of the top narrow part of chamber = 1.4

E = height of cylindrical part of chamber in cm

9.2 Data Processing Sequence

Page 9
9.2.1 Processing Steps

The peak areas were taken directly from the HP ChemStation reports from the GC. They were

entered into spreadsheets, and the concentrations were calculated using the formulas in Section 9.1.

The spreadsheets then automatically calculated the flux using the formulas in Section 9.1.

The flux equation included the slope of the regression line of the five samples the height and

volume of the chamber and air temperature (see above). Fluxes were calculated by linear regression of

the concentration change in the five samples. If one sample deviated from the line, the flux was

recalculated without the outlier. The correlation coefficient of the regression had to be significant to the

95% confidence limit for n=4 or 5 (r2 = 0.95 or 0.87); otherwise, the sample was rejected. Sites with

ebullition were kept in the data set even if a large increase was observed between two of the samples as

long as the correlation coefficient was still significant at p < 0.05.

9.3.2 Calculated Variables

Refer to Section 9.1.1.

9.4 Graphs and Plots

None given.

10. Errors

10.1 Sources of Error

Field sampling error could account for some error in the concentration of the syringe samples:

• Not flushing the sampling line from the chamber before sampling could cause dilution of the

sample with air from the last sampling time.

• Not completely closing the syringes or allowing them to come open during transport will

cause dilution from ambient air.

Errors such as these would have been written down in the lab/field books, and these data have been

edited out. The analytical precision of the GCs is 0.2% for CHIn.

10.2 Quality Assessment

10.2.1 Data Validation by Source
