On the potential of very high-resolution repeat DEMs in glacial and periglacial environments
very high-resolution repeat DEMs glacial and periglacial environments
2010/2/3
The potential of high-resolution repeat DEMs was investigated for glaciological applications including periglacial features (e.g. rock glaciers). It was shown that glacier boundaries can be delineated...
Spring molybdenum enrichment in scallop shells: a potential tracer of diatom productivity in temperate coastal environments (Brittany, NW France)
Spring molybdenum enrichment scallop shells diatom productivity temperate coastal environments
2010/1/21
Skeletal molybdenum/calcium ([Mo]/[Ca])shell ratios were examined in shells of the Great Scallop Pecten maximus collected in temperate coastal environments of Western Europe (42 to 49° N). These ratio...
LiDAR for monitoring mass movements in permafrost environments at the cirque Hinteres Langtal, Austria, between 2000 and 2008
LiDAR mass movements permafrost environments cirque Hinteres Langtal
2009/12/8
Permafrost areas receive more and more attention in terms of natural hazards in recent years due to ongoing global warming. Active rockglaciers are mixtures of debris and ice (of different origin) in ...
Late Quaternary,cryoplanation of rock surfaces in lacustrine environments in the Bergen area,Norway
Late Quaternary cryoplanation rock surfaces lacustrine environments
2009/12/3
Relatively horizontal and smooth rock surfaces bordering lakes 65-150 m a.s.l. in the relatively mountainous Bergen area are described. The surfaces,1- 4 km2 in size and up to 1.5 km wide are develope...
Interpretation of benthic foraminiferal stable isotopes in subtidal estuarine environments
Interpretation benthic foraminiferal stable isotopes subtidal estuarine environments
2010/1/21
Here we present a novel approach for the interpretation of stable isotope signatures recorded in benthic foraminifera from subtidal estuarine environments. The stable isotopic composition (δ18O and δ1...
Distribution of lipid biomarkers and carbon isotope fractionation in contrasting trophic environments of the South East Pacific
lipid biomarkers carbon isotope fractionation trophic environments Pacific
2010/1/15
The distribution of lipid biomarkers and their stable carbon isotope composition was investigated on suspended particles from different contrasting trophic environments at six sites in the South East ...
A global comparison of four potential evapotranspiration equations and their relevance to stream flow modelling in semi-arid environments
global comparison potential evapotranspiration equations stream flow modelling
2010/1/28
This study compares four different potential evapotranspiration equations according to Priestley Taylor, Kimberly Penman, Penman Monteith (FAO-56) and Hargreaves on a global basis to demonstrate their...
High-resolution ice nucleation spectra of sea-ice bacteria:implications for cloud formation and life in frozen environments
High-resolution ice nucleation spectra sea-ice bacteria cloud formation
2010/1/15
Even though studies of Arctic ice forming particles suggest that a bacterial or viral source derived from open leads could be important for ice formation in Arctic clouds (Bigg and Leck, 2001), the ic...
Analysis of the environments of seven Mediterranean tropical-like storms using an axisymmetric,nonhydrostatic,cloud resolving model
environments seven Mediterranean tropical-like storms cloud resolving model
2009/12/30
Tropical-like storms on the Mediterranean Sea are occasionally observed on satellite images, often with a clear eye surrounded by an axysimmetric cloud structure. These storms sometimes attain hurrica...
Water use strategies and ecosystem-atmosphere exchange of CO2 in two highly seasonal environments
Water use strategies ecosystem-atmosphere exchange CO2 seasonal environments
2010/1/13
We compare assimilation and respiration rates, and water use strategies in four divergent ecosystems located in cold-continental central Siberia and in semi-arid southern Africa. These seemingly unrel...
