BOREAS TE-05 Leaf Gas Exchange Data

J.R. BROOKS, L. FLANAGAN & A. LETHBRIDGE
The BOREAS group TE-05 collected measurements in the NSA and SSA on gas exchange, gas composition and tree growth. The leaf photosynthetic gas exchange data were collected in the BOREAS NSA and the SSA using a Li-Cor 6200 portable photosynthesis system. The data were collected to compare the photosynthetic capacity, stomatal conductance and leaf intercellular CO2 concentrations among the major tree species at the BOREAS sites. The data are average values from diurnal measurements on...

BOREAS TGB-05 Fire History of Manitoba 1980 to 1991 in Raster Format

B.J. STOCKS, R.G. ZEPP & D.E. KNAPP
This raster format data set covers the province of Manitoba. The data were gridded into the AEAC projection from the original vector data. The original vector data were produced by Forestry Canada from hand-drawn boundaries of fires on photocopies of 1:250,000-scale maps. The locational accuracy of the data is considered fair to poor. When the locations of some fire boundaries were compared to Landsat TM images, they were found to be off by as much...

ISLSCP II HYDRO1k Elevation-derived Products

K.L. VERDIN
This data set contains coarse scale elevation and elevation-based parameters at 1.0 and 0.5-degree spatial resolutions that were developed to support a wide variety of global modeling activities through the International Satellite Land Surface Climatology Project (ISLSCP) Initiative II data collection. These coarse scale data have sufficient statistical information (up to fourth moment) to allow a good statistical description of the sub-cell distribution of any particular elevation parameter (i.e. elevation, slope and aspect). The database...

Mineral composition of mid-ocean-ridge basalts from ODP Leg 187 sites, supplement to: Sato, Hiroshi (2004): Mineral compositions of MORB from the Australian Antarctic Discordance (AAD): implications for mantle source characteristics. In: Pedersen, RB; Christie, DM; Miller, DJ (eds.) Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 187, 1-26

Hiroshi Sato
The chemical compositions of olivine, plagioclase, pyroxene, and spinel in lavas collected during Ocean Drilling Program Leg 187 in the Australian Antarctic Discordance, Southeast Indian Ridge (41°-46°S, 126°-135°E) were analyzed, and modeling of the theoretical equilibrium petrogenetic conditions between olivine and melt was conducted. The cores of larger olivine phenocrysts, particularly in the isotopic Indian-type mid-ocean-ridge basalt (MORB), are not equilibrated with melt compositions and are considered to be xenocrystic. Larger plagioclase phenocrysts with compositionally...

Nature, 488(7409), 73-77

Jörg Pross, Lineth Contreras, Peter K Bijl, David R Greenwood, Steven M Bohaty, Stefan Schouten, James A Bendle, Ursula Röhl, Lisa Tauxe, J Ian Raine, Claire E Huck, Tina van de Flierdt, Stewart S R Jamieson, Catherine E Stickley, Bas van de Schootbrugge, Carlota Escutia Dotti, Henk Brinkhuis & IODP Expedition 318 Scientists
The warmest global climates of the past 65 million years occurred during the early Eocene epoch (about 55 to 48 million years ago), when the Equator-to-pole temperature gradients were much smaller than today (doi:10.1130/0091-7613(1995)023<1044:ECCALT>2.3.CO;2, doi:10.1038/nature08399) and atmospheric carbon dioxide levels were in excess of one thousand parts per million by volume (doi:10.1016/j.gca.2003.09.002, doi:10.1038/ngeo1186). Recently the early Eocene has received considerable interest because it may provide insight into the response of Earth's climate and biosphere to...

Root Biomass Data (FIFE)

T.R. SEASTEDT & C.L. TURNER
The FIFE Root Biomass data were collected from 16 locations within the FIFE study area during the 1987 growing season. They provide a measure of the below-ground biomass for the study area. Biomass reported as grams per square m assumes that the depth of the core samples is sufficient to include all root biomass under the surface to an infinite depth. Prairie vegetation does possess roots deeper than the 20 cm coring, however, the fraction...

NPP Multi-Biome: TEM Calibration Data, 1992, R1

D.W. KICKLIGHTER
This data set contains one ASCII data file (.csv format) that is known as the "TEM data set." The data provide pool sizes and fluxes of carbon (C) and nitrogen (N) for 16 globally distributed field sites that represent a wide range of terrestrial biomes, tundra to tropical forest, but exclude wetlands. The NPP data were extracted from the literature. They were not previously widely available to the ecosystem modeling community in electronic form until...

Soil Impedance Data (FIFE)

S.G. UNGAR
The purpose of this research was to characterize the soil moisture distribution in the FIFE study area. Daily measurements of the soil dielectric properties were obtained at five locations throughout the FIFE study area during the 1987 Intensive Field Campaigns (IFC). Calculated soil volumetric water contents were compared with gravimetric soil moisture measurements collected at the same locations by the FIFE staff science team. Examination of the data revealed that the impedance probe is a...

TransCom 3: Annual Mean CO2 Flux Estimates from Atmospheric Inversions (Level 1)

K.R. GURNEY & A.S. DENNING
The Atmospheric Tracer Transport Model Intercomparison Project (TransCom) was created to quantify and diagnose the uncertainty in inversion calculations of the global carbon budget that results from errors in simulated atmospheric transport, the choice of measured atmospheric carbon dioxide data used, and the inversion methodology employed. Under the third phase of TransCom (TransCom 3), surface-atmosphere CO2 fluxes were estimated from an intercomparison of 16 different atmospheric tracer transport models and model variants in order to...

T. KIRA
This data set contains one net primary productivity (NPP) data file and three climate data files (.txt format) for a fully closed tropical rainforest in the Khao Chong Reserve (7.58 N 99.8 E) in southern Thailand. The Reserve comprises 500 ha of well-preserved rainforest considered typical of the region, although maximum tree height (36 m) and biodiversity were less than in Malaysian forests. Net primary productivity (NPP) was estimated as the sum of annual net...

BOREAS TGB-05 CO2, CH4, and CO Chamber Flux Data over the NSA

R.G. ZEPP

This data set contains carbon dioxide (CO2), methane (CH4), and carbon monoxide (CO) chamber flux measurements conducted in 1994 at upland forest sites that experienced stand- replacement fires. These measurements were acquired to understand the impact of fires on soil biogeochemistry and related changes in trace gas exchange in boreal forest soils. Relevant ancillary data, including data...
