Annual Variation of Local Photon Emissions’ Spectral Power within the mHz Range Overlaps with Seismic-Atmospheric Acoustic Oscillations
Photon Emissions Earth Oscillations Spheroidal Modes
2013/3/7
Spheroidal modes of seismic and acoustic oscillations in the atmosphere occur within the 2 to 7 mHz range with peak-to-peak variations in the order of 10–12 to 10–11 m·s–2. Previous research indicated...
Multi-Satellite and Sensor Derived Trends and Variation of Snow Water Equivalent on the High-Latitudes of the Northern Hemisphere
Arctic Snow Water Equivalent Multi-Satellite Microwave Trends and Variations
2013/3/7
Utilizing more than 30 years of satellite-microwave sensor derived snow water equivalent data on the high-latitudes of the northern hemisphere we investigate regional trends and variations relative to...
Heavy precipitation episodes and cosmic rays variation
Heavy precipitation episodes cosmic rays variation
2010/1/27
In this paper an attempt is made to investigate the possible temporal correlation between heavy precipitation episodes and cosmic rays' activity, on various time scales. Cosmic rays measurements are s...
Needle age-related and seasonal photosynthetic capacity variation is negligible for modelling yearly gas exchange of a sparse temperate Scots pine forest
Needle age-related and seasonal photosynthetic capacity variation a sparse temperate Scots pine forest
2010/1/21
In this study, we quantified the predictive accuracy loss involved with omitting photosynthetic capacity variation for a Scots pine (Pinus sylvestris L.) stand in Flanders, Belgium. Over the course of...
Short scale (6 h) temporal variation of sinking fluxes of planktonic and terrigeneous lipids at 200 m in the NW Mediterranean Sea
Short scale (6 h) temporal variation planktonic and terrigeneous lipids the NW Mediterranean Sea
2010/1/21
Drifting sediment trap measurements were carried out at high temporal frequency in the northwestern Mediterranean Sea in the course of the DYNAPROC 2 campaign, during the transition between late summe...
Recent variation of the Las Vacas Glacier Mt. Aconcagua region, Central Andes, Argentina, based on ASTER stereoscopic images
Las Vacas Glacier Mt. Aconcagua region Central Andes ASTER stereoscopic images
2010/1/28
This work presents the results of the ASTER stereoscopic image processing to calculate the volume changes of Las Vacas Glacier. The processing of medium resolution satellite images (ASTER level 1A – p...
Relation between integral effect of sub-surface temperature variation (I) and seismic effects
integral effect sub-surface temperature variation seismic effects
2009/12/10
There will be a change in the Earth's local sub-surface thermal structure before and/or after an earthquake. In this work we have introduced a new parameter (I) which relates integral effect of temper...

Measuring and modelling seasonal variation of gross nitrification rates in response to long-term fertilisation
seasonal variation gross nitrification rates long-term fertilisation
2010/1/21
The formation of nitrate (nitrification) in soils is an important process that influences N availability for plant uptake and potential N losses as well. Gross nitrification is an effective measure by...
