Ronan Autret, Serge Suanez, Bernard Fichaut, Samuel Etienne. (2016). Elaboration d’une typologie des dépôts de blocs supratidaux de sommets de falaise de la péninsule de Reykjanes (Islande); Development of a typology of cliff-top storm deposits of the Rekjanes Peninsula (Iceland) (Vol. 22). Bachelor's thesis, , .
Abstract: Cette étude porte sur la répartition et la morphologie des dépôts grossiers de tempêtes (25,6 cm ≤ l ≤ 820 cm) qui se trouvent en retrait du sommet des falaises de la péninsule de Reykjanes, au sud-ouest de l’Islande. Les 35 km de linéaire côtier sur lesquels porte ce travail sont constitués de falaises, hautes au maximum de 15 mètres, taillées dans un substrat basaltique postglaciaire d’âge compris entre 14 500 et 800 ans BP. L’origine de ces dépôts est marine et est attribuée à l’action des vagues engendrées par les dépressions atlantiques, vagues dont les hauteurs significatives pour une période de retour de 100 ans atteignent 17,4 mètres dans ce secteur. Entre les mois d’avril et juin 2014, un travail de terrain a permis d’étudier 35 accumulations supratidales de blocs à partir d’observations qualitatives et de relevés topomorphologiques. L’analyse de ces données montre que l’altitude du sommet des falaises n’est pas un facteur limitant à la formation de ces dépôts sur la péninsule de Reykjanes. Au contraire, le contexte lithostructural des coulées de lave et les spécificités hydrodynamiques locales qui influent sur la morphologie des falaises sont prédominantes dans la formation et la disposition des différents types d’accumulations. The present study focuses on the distribution and morphology of cliff-top storm deposits (CTSD) in the Reykjanes Peninsula in southwest Iceland. The study area stretches over a 35 kilometre coastline and consists mainly of cliffs not exceeding 15 m, cut into post-glacial lava beds aged 14 500 to 800 yr BP. The origin of these deposits cannot be related to tsunamis since none has been recorded in this area within this period. It is due to the action of North Atlantic waves whose significant height, measured between 1994 and 2004, can reach 17.4 m in this area. During a field survey from April to June, 2014, 35 CTSD sites were studied mainly through qualitative observations and topomorphological measurements. The analysis of the data shows that the organisation and distribution of CTSD in the Reykjanes peninsula do not depend on the cliff height. In contrast, the lithostructural characteristics of the lava beds and local variations in hydrodynamism, both of which determine the morphology of cliffs, appear to be decisive factors in explaining these aspects of CTSD in this area.

ZalianCyrus, ChadidMerieme, . (2013). Antarctica photometric survey using PDM13
(Vol. 9).
Abstract: PDM13 is a new graphic interface program dedicated to frequency domain analysis based on the Phase Dispersion Minimization technique (PDM, Stellingwerf 2012). In this paper, we will present the different algorithms running in PDM13, including the Auto-Segmentation, the Gauss-Newton and the PDM algorithms. More details on this triptych are available in our recent paper (Zalian et al., submitted). Their aim is to offer a simple and powerful way to extract frequency. Amongst the numerous improvements offered by the program, we will particularly focus on the reduction of aliases and the ability to look directly for multiple-period phenomena and the Blazhko effect. After that, we will show the first results from PDM13 using the Antarctica photometric survey.

Abstract: When females copulate with multiple males the potential exists for female sperm choice. Females may increase the probability of being fertilized by preferred males by selectively retaining their sperm while ejecting the sperm of unfavoured males. An alternative criterion to male quality for female sperm choice may be sperm age because old sperm degrade and can lead to zygote death or unhealthy offspring. Here, we report that in a genetically monogamous bird, the black-legged kittiwake Rissa tridactyla, females eject their mates' sperm according to when the copulations were performed. Following copulations that were performed approximately two weeks before egg laying, females ejected inseminations at high frequencies while retaining inseminations that occurred soon before laying. Females that suffered hatching failure had ejected sperm from early copulations less than half as frequently as females whose entire clutches hatched. Furthermore, chicks that hatched from eggs fertilized by old sperm were in poor condition relative to those fertilized by young sperm. These findings support the 'young sperm' hypothesis, which predicts that females choose fresh sperm to avoid reproductive failure and are the first to show intra-male sperm choice by females.

. Marine Geodesy, 35(sup1), 299–313.
Abstract: Through a validation exercise in the Kerguelen Island over 13 global, regional, and local tidal atlases, we have demonstrated the superiority of finite element high resolution model at the coast. The evaluation of different tidal geophysical corrections on the de-aliasing performance of the Jason-2 mission exhibited strong differences in the coastal domain (<10?20 km from the coast) with SLA variance reduction that can reach up to 30% from one model to another. The lack of resolution is pointed out as a possible responsible of these difference.

(2017). Gastrointestinal parasites of two populations of Arctic foxes (Vulpes lagopus) from north-east Greenland (Vol. 36). Bachelor's thesis, , .
Abstract: Parasitological examination of 275 faecal samples from Arctic foxes (Vulpes lagopus) collected at Zackenberg Valley and Karupelv Valley in north-east Greenland from 2006 to 2008 was conducted using sieving and microscopy. Overall, 125 (45.5%) samples contained parasite eggs of Taenia crassiceps, Taenia serialis, Toxascaris leonina, Eucoleus boehmi, Physalopteridae and Ancylostomatidae, and Strongyloides-like larvae. As long-term ecological studies are conducted at both sampling locations, the present findings constitute a baseline data set for further parasitological monitoring.
