On the estimate of earthquake magnitude at a local seismic network
southeastern Sicily digital seismic network magnitude
2015/9/28
We investigated possible uncertainties and biases of magnitude estimate arising from instrument characteristics, site conditions and routine data processing at a local seismic network running in South...
In order to verify the duration magnitude MD we calculated local magnitude ML values of 288 earthquakes occurring
from October 2002 to April 2003 at Mt. Etna. The analysis was computed at three digit...
The collocation approach to Moho estimate
Moho Gravity collocation Gravimetric inverse problem
2015/8/17
In this paper, the collocation approach to Moho estimate is presented. This method is applied to the inversion of gravity data that can be complemented by Moho depth information coming from e.g. seism...
Use of the breeding technique to estimate the structure of the analysis errors of the day
breeding technique structure of the analysis errors of the day
2009/11/12
A 3D-variational data assimilation scheme for a quasi-geostrophic channel model (Morss, 1998) is used to study the structure of the background error and its relationship to the corresponding bred vect...
A mechanistic modelling and data assimilation approach to estimate the carbon/chlorophyll and carbon/nitrogen ratios in a coupled hydrodynamical-biological model
mechanistic modelling data assimilation approach carbon/chlorophyll and carbon/nitrogen ratios
2009/11/11
The principal objective of hydrodynamical-biological models is to provide estimates of the main carbon fluxes such as total and export oceanic production. These models are nitrogen based, that is to s...
Isostatic Compensation in Western Anatolia with Estimate of the Effective Elastic Thickness
effective elastic thickness isostatic response functions gravity Western Anatolia admittance analysis
2009/7/7
Isostasy is concerned with how the crust and mantle adjusts to shifting loads of limited spatial and temporal dimensions. By analysing the frequency content of gravity and topography data, it has been...
An Improved Estimate for the Long-Term Mean Sea Level on the Finnish Coast
sea level Baltic Sea water balance NAO index theoretical mean sea level
2009/6/9
The main factors affecting the long-term mean sea level on the Finnish coast are the land uplift,the rise of the global mean sea level and the water balance of the Baltic Sea. The sea level variabilit...
