Les formations carbonatées du Dortan (Ain) : premières observations
1986
Calcium carbonate, deposits have built four terraces, near Dortan, in the Southern part of Central Jura (46° lat. N). These deposits may just cover other terraces associated themselves with an ice-dammed lake. They include two types : 1) tufa deposits, porous and hard, with conspicuous tree remains ; 2) lake chalk, compact and brittle, snowing lenses and, sometimes, varves, with shells and pieces of charcoal. C 14 dating and analyses should allow to insert these deposits in the Jura Holocene chronology and to explain their situation at such a high latitude.
Urban Surface Energy Balance Models: Model Characteristics and Methodology for a Comparison Study
2009
Many urban surface energy balance models now exist. These vary in complexity from simple schemes that represent the city as a concrete slab, to those which incorporate detailed representations of momentum and energy fluxes distributed within the atmospheric boundary layer. While many of these schemes have been evaluated against observations, with some models even compared with the same data sets, such evaluations have not been undertaken in a controlled manner to enable direct comparison. For other types of climate model, for instance the Project for Intercomparison of Land-Surface Parameterization Schemes (PILPS) experiments (Henderson-Sellers et al., 1993), such controlled comparisons hav…

Methodology for the estimation of the increase in time loss due to future increase in tropical cyclone intensity in Japan
2009
Published version of an article from the journal: Climatic Change. The original publication is available at Spingerlink. http://dx.doi.org/10.1007/s10584-009-9725-9 The present paper develops a methodology for estimating the risks and consequences of possible future increases in tropical cyclone intensities that would allow policy makers to relatively quickly evaluate the cost of different mitigation strategies. The methodology simulates future tropical cyclones by modifying the intensity of historical tropical cyclones between the years 1978 and 2007. It then uses a Monte Carlo Simulation to obtain the expected number of hours that a certain area can expect to be affected by winds of a giv…
Harmonizing circumpolar monitoring of Arctic fox: benefits, opportunities, challenges and recommendations.
2017
Source at http://dx.doi.org/10.1080/17518369.2017.1319602 The biodiversity working group of the Arctic Council has developed pan-Arctic biodiversity monitoring plans to improve our ability to detect, understand and report on long-term change in Arctic biodiversity. The Arctic fox (Vulpes lagopus) was identified as a target of future monitoring because of its circumpolar distribution, ecological importance and reliance on Arctic ecosystems. We provide the first exhaustive survey of contemporary Arctic fox monitoring programmes, describing 34 projects located in eight countries. Monitored populations covered equally the four climate zones of the species’ distribution, and there were large dif…
Effects of simulated environmental changes on growth and growth form in a late snowbed population of pohlia wahlenbergii (Web. et Mohr) Andr
2003
In a factorial field experiment we increased the temperature (Open Top Chambers) and nutrients (nitrogen, phosphorus, and potassium [NPK]) to simulate predicted future climate changes and studied the growth response of the acrocarpous bryophyte Pohlia wahlenbergii (Bryaceae) in a wet snowbed environment. The species shows a positive growth-length response to added nutrients and increased temperature. The stronger response to nutrients indicates a strong limitation of nutrients in the snowbed environment. There was an immediate response to nutrient treatment, whereas the temperature response was delayed. The growth response shows a clear interaction between temperature and nutrients. The imm…
Forholdet mellom elevers motivasjon for kroppsøvingsfaget, motivasjonsklima og tilhørighet i kroppsøvingstimene, og deres intensjon om å være fysisk …
2021
Studiens hensikt var å undersøke forholdet mellom elevers tilhørighet i kroppsøvingstimene, deres opplevelse av motivasjonsklimaet i faget og deres intensjon om å være fysisk aktive etter endt obligatorisk skolegang, samt å undersøke i hvilken grad autonom og kontrollert motivasjon medierte det ovennevnte forholdet. Tverrsnittsdata fra 2610 avgangselever ved ungdoms- og videregående skoler fra fire forskjellige geografiske områder i Norge dannet grunnlaget for mediasjonsanalysen. Denne målte indirekte effekter ved hjelp av en bias-korrigert bootstrapping metode. Resultatene viste at opplevd tilhørighet og opplevd mestringsklima i faget var positivt assosiert med elevers intensjoner om å vær…
Automatic Relative Radiometric Normalization of Bi-Temporal Satellite Images Using a Coarse-to-Fine Pseudo-Invariant Features Selection and Fuzzy Int…
2022
Relative radiometric normalization (RRN) is important for pre-processing and analyzing multitemporal remote sensing (RS) images. Multitemporal RS images usually include different land use/land cover (LULC) types; therefore, considering an identical linear relationship during RRN modeling may result in potential errors in the RRN results. To resolve this issue, we proposed a new automatic RRN technique that efficiently selects the clustered pseudo-invariant features (PIFs) through a coarse-to-fine strategy and uses them in a fusion-based RRN modeling approach. In the coarse stage, an efficient difference index was first generated from the down-sampled reference and target images by combining…
