The NASA STI Program Office ... in Profile

Since its founding, NASA has been dedicated to

the advancement of aeronautics and space

science. The NASA Scientific and Technical

Information (STI) Program Office plays a key

part in helping NASA maintain this important

role.

The NASA STI Program Office is operated by

Langley Research Center, the lead center for

NASA's scientific and technical information. The

NASA STI Program Office provides access to

the NASA STI Database, the largest collection of

aeronautical and space science STI in the world.

The Program Office is also NASA's institutional

mechanism for disseminating the results of its

research and development activities. These

results are published by NASA in the NASA STI

Report Series, which includes the following

report types:

• TECHNICAL PUBLICATION. Reports of

completed research or a major significant

phase of research that present the results of

NASA programs and include extensive data or

theoretical analysis. Includes compilations of

significant scientific and technical data and

information deemed to be of continuing

reference value. NASA's counterpart of

peer-reviewed formal professional papers but

has less stringent limitations on manuscript

length and extent of graphic presentations.

• TECHNICAL MEMORANDUM. Scientific

and technical findings that are preliminary or

of specialized interest, e.g., quick release

reports, working papers, and bibliographies

that contain minimal annotation. Does not

contain extensive analysis.

• CONTRACTOR REPORT. Scientific and

technical findings by NASA-sponsored

contractors and grantees.

CONFERENCE PUBLICATION. Collected

papers from scientific and technical

conferences, symposia, seminars, or other

meetings sponsored or cosponsored by NASA.

SPECIAL PUBLICATION. Scientific, technical, or historical information from NASA

programs, projects, and mission, often concerned with subjects having substantial public

interest.

TECHNICAL TRANSLATION.

English-language translations of foreign scientific and technical material pertinent to NASA's

mission.

Specialized services that complement the STI

Program Office's diverse offerings include creating custom thesauri, building customized databases, organizing and publishing research results...

even providing videos.

BOREAS TGB-3 Plant Species Composition Data over the NSA-Fen

Jill L. Bubier

Summary

The BOREAS TGB-3 team collected several data sets that contributed to understanding the measured

trace gas fluxes over sites in the NSA. This data set contains information about the composition of

plant species that were within the collars used to measure NEE. The species composition was

identified to understand the differences in NEE among the various plant communities in the NSA fen.

The data were collected in July of 1994 and 1996. The data are contained in comma-delimited, ASCII

files.

1.1 Data Set Identification

BOREAS TGB-03 Plant Species Composition Data over the NSA Fen

1.2 Data Set Introduction

As part of the BOReal Ecosystem-Atmosphere Study (BOREAS), the Trace Gas Biogeochemistry

(TGB)-03 team measured plant species within the net ecosystem exchange (NEE) collars to understand

the differences in NEE among the various plant communities in the Northern Study Area (NSA) fen.

Measurements were made from the period of snow melt and thaw through the full growing season to

fall freeze up to examine the seasonal patterns of NEE, differences in phenology, and relative

importance of vascular plants and bryophytes to the carbon balance. The following is a description of

the acquisition of data and the final data sets.

1.4 Summary of Parameters

The plant communities for each chamber were characterized.

1.5 Discussion

Plant species compositions were measured at four subsites in the NSA fen, designated as collapse

bog (CB), collapse fen (CF), tower fen (TF), and Zoltai fen (ZF). A spur (1, 2, 3, or 4) designates

each collar location along the boardwalk at each subsite. The collars are further designated by the

microtopography or dominant ground cover of the collar location: pal=paisa, hk=hummock,

hw=hollow, lwn=lawn, moat=open water at the edge of the collapse scars, b_moss=brown moss,

sph=sphagnum, and lich=lichen. The plant species composition of each collar where NEE

measurements were taken was recorded as percent cover of the total collar area. The plant data for each

collar at all four subsites are located in one American Standard Code for Information Interchange

(ASCII) (DOS)-delimited text file: fen96_pla.txt.

3. Theory of Measurements

Plant species composition within the NEE collars was identified to understand the differences in net

CO2 exchange among the various plant communities in the fen.

4. Equipment

4.1 Sensor/Instrument Description

4.1.1 Collection Environment

Data were collected in mid-July of 1994 and 1996. Deciduous and annual plants would be expected

to be fully leafed out at this time.

4.1.2 Source/Platform

The TGB-03 team members identified the plant species within the collars. One of two chamber

sizes was used to measure NEE depending on the height of the vegetation. The larger chamber covered

3,660 cruZ of surface area and was 90.5 cm in height. The smaller chamber covered the same area as

the larger chamber to fit the same collars (3,660 cruZ), but was half the height (45 cm).

4.1.3 Source/Platform Mission Objectives

The objective was to determine the plant composition within the collars to help determine

differences in observed NEE measurements.

4.1.4 Key Variables

The key variable measured during the sampling period was plant species composition.

5. Data Acquisition Methods

Plant species composition was recorded in each collar during the height of the growing season in

mid-July 1996. Visual estimates of percent cover of each vascular plant and bryophyte species were

made using the light/canopy intercept method (Daubenmire, 1968). Each species was assigned a

percent cover value based on an estimate of spatial coverage (relative to the total area of the collar)

when the canopy of that species was visually projected to the ground below. Percent cover of all

species totals over 100 percent for each collar because of several layers of vegetation. Specimens for

each unknown species were collected in plant communities outside of the collars and identified in the

lab at the Heritage North Museum, Thompson, Manitoba, or at Dr. Barry Rock's laboratory at

Complex Systems Research Center, University of New Hampshire (UNH), Durham, NH.

7. Data Description

7.1 Spatial Characteristics

7.1.1 Spatial Coverage

The collars were placed so as to cover the environmental gradients in the TF complex, an area

approximately 6 km2. Global Positioning System (GPS) coordinates based on the North Amercian

Datum of 1983 (NAD83) for the major sampling locations are:

Site N Latitude Sdev W Longitude Sdev Elevation Sdev

CB 55°55'4.931 '' 2.75 98025'5.294 '' 1.18 217.20 3.86

ZF 55055'5.477 '' 2.07 98025'26.396 '' 1.29 217.10 3.11

CB collars were located in a small, circular collapse scar (75 m diameter) almost completely

surrounded by permafrost peat plateau, behind the generator shed. Three spurs were located

perpendicular to the boardwalk. Spur 1 was adjacent to the moat, or open water area; spur 2 was in a

hummock-hollow area; and spur 3 was in the center of the collapse scar. In addition to the collars in

the collapse scar, this subsite had two collars on the palsa (frozen peat plateau) adjacent to the collapse

scar. Collar designations were as follows:

CBlmoat = collapse bog, spur i, moat

CB2hk = collapse bog, spur 2, hummock

CB2hw = collapse bog, spur 2, hollow

CB3hk = collapse bog, spur 3, hummock

Cbpalmoss : collapse bog, palsa, moss

Cbpallich : collapse bog, palsa, lichen

spurs were located perpendicular to the main boardwalk. Spur 1 was just beyond the moat at the

beginning of the boardwalk in a treed area of tamarack (Larix laricina), spur 2 was in a tall shrub zone

(Betula glandulosa), spur 3 was in a low shrub zone just before the hut, and spur 4 was just beyond

the hut in a mixed low shrub/sedge zone. Collar designations were as follows:

TFlhk = tower fen, spur i, hummock

TF2hk = tower fen, spur 2, hummock

TF2hw = tower fen, spur 2, hollow

TF3hk = tower fen, spur 3, hummock

TF3hw = tower fen, spur 3, hollow

TF4hw = tower fen, spur 4, hollow

ZF collars were located in a sedge-dominated (Carex sp.) fen area of the peatland complex, north of

the fen tower, and accessed from Route 391. Three spurs were located perpendicular to the main

boardwalk. Spur 1 was on a treed ridge; spur 2 was in a shrub-dominated hummock-hollow area; and

spur 3 was in a wet, sedge-dominated area near the edge of a palsa. Collar designations were as

follows:

ZFlhk = zoltai fen, spur i, hummock

ZF2hk = zoltai fen, spur 2, hummock

ZF2hw = zoltai fen, spur 2, hollow

ZF3b moss = zoltai fen, spur 3, brown moss

13. ABSTRACT (Maximum 200 words)

The BOREAS TGB-3 team collected several data sets that contributed to understanding the measured

trace gas fluxes over sites in the NSA. This data set contains information about the composition of

plant species that were within the collars used to measure NEE. The species composition was identified to understand the differences in NEE among the various plant communities in the NSA fen. The

data were collected in July of 1994 and 1996. The data are contained in comma-delimited, ASCII files.

14. SUBJECT TERMS
