BOREAS Follow-On DSP-09 Moss Cover Classification at Three Area Scales

G. RAPALEE, F.G. HALL, L.T. STEYAERT & E.R. LEVINE
BOREAS follow-on group DSP-9 mapped surface moss type at three scales (1 km, 30 m, and 10 m) based on observed associations between moss cover and land cover type. In the BOREAS Northern (NSA) and Southern (SSA) Study Areas, we utilized land cover derived from Landsat TM (30 m) and ground measurements/observations, soils maps, and field observations to establish associations between moss and land cover. At the BOREAS regional scale, the 1 km moss cover...

BOREAS Level-0 AOCI Imagery: Digital Counts in BIL Format

J.S. MYERS
The level-0 AOCI imagery, along with the other remotely sensed images, was collected to provide spatially extensive information about radiant energy over the primary BOREAS study areas. The AOCI was the only remote sensing instrument flown with wavelength bands specific to the investigation of various aquatic parameters such as chlorophyll content and turbidity. Only one flight of the AOCI instrument was made onboard the ER-2 aircraft on 21-Jul-1994 over the SSA. Companion files include (1)...

Amino acids from ODP Holes 117-722B and 177-724C, supplement to: Möbius, Jürgen; Gaye, Birgit; Lahajnar, Niko; Bahlmann, Enno; Emeis, Kay-Christian (2011): Influence of diagenesis on sedimentary d15N in the Arabian Sea over the last 130 kyr. Marine Geology, 284(1-4), 127-138

Jürgen Möbius, Birgit Gaye, Niko Lahajnar, Enno Bahlmann & Kay-Christian Emeis
Sedimentary d15N records are valuable archives of ocean history but they are often modified during early diagenesis. Here we quantify the effect of early diagenetic enrichment on sedimentary N-isotope composition in order to obtain the pristine signal of reactive N assimilated in the euphotic zone. This is possible by using paired data of d15N and amino acid composition of sediment samples, which can be applied to estimate the degree of organic matter degradation. We determined...

Organic carbon and nitrogen, sediment composition, and clay mineralogy of Deep Sea Drilling Project Site 603, western Atlantic Ocean, supplement to: Emeis, Kay-Christian; Mycke, Bernd; Richnow, H-H; Spitzy, Alejandro; Degens, Egon T (1987): Organic carbon and nitrogen, sediment composition, and clay mineralogy of Deep Sea Drilling Project Site 603, western Atlantic Ocean. In: van Hinte, JE; Wise, SW Jr; et al. (eds.), Initial Reports of the Deep Sea Drilling Project, Washington (U.S. Govt. Printing Office), 93, 1245-1256

Kay-Christian Emeis, Bernd Mycke, H-H Richnow, Alejandro Spitzy & Egon T Degens
Sediment and interstitial water samples recovered during DSDP Leg 93 at Site 603 (lower continental rise off Cape Hatteras) were analyzed for a series of geochemical facies indicators to elucidate the nature and origin of the sedimentary material. Special emphasis was given to middle Cretaceous organic-matter-rich turbidite sequences of Aptian to Turanian age. Organic carbon content ranges from nil in pelagic claystone samples to 4.2% (total rock) in middle Cretaceous carbonaceous mudstones of turbiditic origin....

Organic compounds at DSDP Hole 90-593, supplement to: Mycke, Bernd; Emeis, Kay-Christian; Degens, Egon T (1986): Diagenesis of organic compounds in Hole 593, Leg 90 (Tasman Sea). In: Kennett, JP; von der Borch, CC; et al. (eds.), Initial Reports of the Deep Sea Drilling Project, Washington (U.S. Govt. Printing Office), 90, 1265-1269

Bernd Mycke, Kay-Christian Emeis & Egon T Degens
Corg and Norg contents in the acid insoluble mineral fraction were studied in sediments of Site 593. Both decrease systematically from Recent to early Miocene over 425 m of carbonate facies. C/N ratios (7-11) are typically marine and indicate that residual organic matter, bound to clay minerals, was originally scavenged from the marine habitat rather than being of terrigenous origin. Variations of Corg and Norg are almost entirely controlled by rates of sedimentation, which gradually...

Water chemistry and fluffy layer geochemistry and mineral content at four sites in the western Baltic Sea, supplement to: Löffler, Annekatrin; Leipe, Thomas; Emeis, Kay-Christian (2000): The ''fluffy layer'' in the Pomeranian Bight (western Baltic Sea): geochemistry, mineralogy and environmental aspects. Meyniana, 52, 85-100

Annekatrin Löffler, Thomas Leipe & Kay-Christian Emeis
The fluffy layer was sampled repeatedly during nine expeditions between October 1996 and December 1998 at four stations situated along a S-N-transect from the Oder Estuary to the Arkona Basin. Geochemical and mineralogical analyses of the fluff show regional differences (trends) in composition, attributed to provenance and to hydrographical conditions along their transport pathways. Temporal variability is very high at the shallow water station of the estuary, and decreases towards the deeper stations in the...

Ba, Al and SO4 concentrations in sediments and pore fluid of ODP Leg 127/128 samples, supplement to: von Breymann, Marta T; Brumsack, Hans-Jürgen; Emeis, Kay-Christian (1992): Depositional and diagenetic behavior of barium in the Japan Sea. In: Pisciotto, KA; Ingle, JCJr.; von Breymann, MT; Barron, J; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 127/128(1), 651-665

Marta T von Breymann, Hans-Jürgen Brumsack & Kay-Christian Emeis
The barium distribution in sediments and pore fluids from five sites drilled in the Japan Sea have been used to illustrate the geochemical behavior of this element as it pertains paleoproductivity reconstructions, diagenetic remobilization, and barite precipitation in authigenic fronts.Sites where sulfate is depleted in the pore fluids also show high concentrations of dissolved barium, reflecting dissolution of biogenic barite. The high rate of sedimentation at Sites 798 and 799 results in a rapid sulfate...

Stratigraphy and components of annually laminated (varved) sediments

Dirk Enters & Bernd Zolitschka
Annually laminated (varved) sediment sequences are regarded as one of the most important paleoenvironmental archives because they offer:- accurate „internal" age information in calendar years combined with- exceptional high temporal resolution down to a subannual timescale.This online varve image library shows different varve types, their seasonal sublaminae and successions as well as their components. This site is intended to summarize and distribute existing image information about varves, allow a better start of students and scientists...

CENTURY: Modeling Ecosystem Responses to Climate Change, Version 4 (VEMAP 1995)

W.J. PARTON, D.S. OJIMA & D.S. SCHIMEL
The CENTURY model, Version 4, is a general model of plant-soil nutrient cycling that is being used to simulate carbon and nutrient dynamics for different types of ecosystems including grasslands, agricultural lands, forests and savannas. CENTURY is composed of a soil organic matter/ decomposition submodel, a water budget model, a grassland/crop submodel, a forest production submodel, and management and events scheduling functions. It computes the flow of carbon, nitrogen, phosphorus, and sulfur through the model's...

J. LLOYD, O. KOLLE, E.M. VEENENDAAL, A. ARNETH & P. WOLSKI
To investigate potential contributions of savanna ecosystems to the Earth s carbon balance, an eddy covariance system was used to measure the seasonal variation in carbon dioxide, water vapor, and energy flux at the Maun micrometerological tower site in a broadleaf semi-arid savanna in Southern Africa, approximately 20 km east of Maun in northeastern Botswana. The open woodland studied consists of an overstory dominated by Colophospermum mopane with a sparse understory of grasses and herbs....

Benthic foraminifera in Northwest Indian Ocean surface sediments

J Otto R Hermelin & Graham Shimmield
The relationship between the distribution of benthic foraminifera and sediment type and depositional environment in the Arabian Sea is discussed. The benthic foraminiferal fauna were sampled in nineteen Recent surface sediment samples, and geochemical variables of the sediment of the same samples were measured. The water depths for the box core samples varies from 440 to 4040 m. A total of 103 species and six species-complexes were identified.The geochemical properties were found to correspond well...
