Prionace Glauca) Across Their Life History
Movements of Blue Sharks (Prionace glauca) across Their Life History Frederic Vandeperre1,2*, Alexandre Aires-da-Silva3, Jorge Fontes1,2, Marco Santos1,2, Ricardo Serra˜o Santos1,2, Pedro Afonso1,2 1 Centre of IMAR of the University of the Azores; Department of Oceanography and Fisheries, Horta, Portugal, 2 LARSyS Associated Laboratory, Lisboa, Portugal, 3 Inter- American Tropical Tuna Commission, La Jolla, California, United States of America Abstract Spatial structuring and segregation by sex and size is considered to be an intrinsic attribute of shark populations. These spatial patterns remain poorly understood, particularly for oceanic species such as blue shark (Prionace glauca), despite its importance for the management and conservation of this highly migratory species. This study presents the results of a long- term electronic tagging experiment to investigate the migratory patterns of blue shark, to elucidate how these patterns change across its life history and to assess the existence of a nursery area in the central North Atlantic. Blue sharks belonging to different life stages (n = 34) were tracked for periods up to 952 days during which they moved extensively (up to an estimated 28.139 km), occupying large parts of the oceanic basin. Notwithstanding a large individual variability, there were pronounced differences in movements and space use across the species’ life history. The study provides strong evidence for the existence of a discrete central North Atlantic nursery, where juveniles can reside for up to at least 2 years. In contrast with previously described nurseries of coastal and semi-pelagic sharks, this oceanic nursery is comparatively vast and open suggesting that shelter from predators is not its main function. -

Research in Maritime Archaeology in Portugal 451
450Research in maritimeSHIPWRECKS AROUND archaeology THE WORLD: REVELATIONS in OF THE PAST Portugal: A view of the Past and Present 20 Tiago Miguel Fraga, Cristóvão Fonseca, Inês Pinto Coelho, Jorge Freire, Patrícia Carvalho and André Teixeira, Centro de História de Além-Mar, Universidade Nova de Lisboa and Universidade dos Açores, Lisboa, Portugal Portugal is a country with a secular strategy in overseas expansion, a cultural identity linked to the sea and of a cultural heritage spawning four continents. Thus maritime archaeology has become an essential field to understand the country. Presented here is an overview of the current state of maritime archaeology in Portugal in regard to several projects presently underway in Portugal and their contribution towards Portuguese history and maritime history in general. These occur in diverse fields as coastal knowledge, maritime cultural landscape, coastal archaeology, port studies associated with river and estuary research, ship’s studies and history of shipbuilding. Portugal’s ties to the sea have a secular origin. The geographic shoreline configuration (800 km of shoreline in a border of 1800 km) and abundant waterways and ports, led to an intense riverside settlement, to the development of maritime related economic activities, to a secular navigation knowledge and, of course, the cognitive construction of an entire magico-religious maritime tradition in the territory of present day Portugal. A country with very early defined borders in the late 13th century, Portugal secularly adopted overseas expansion as a main strategy. Its interventions in Africa, America and Asia tried to balance a lack of European expression, enabling a fragile political, economic and even cultural independence. -

Annex 2: Additional Copy of Section B “Geological Heritage” of the Application Section B “Geological Heritage” GEOLOGICAL SUMMARY The Azores Archipelago is located in the North Atlantic, on the triple junction between the North American, Eurasian and African-Nubian plates. Volcanic and tectonic activities are well displayed in the geomorphology of the islands; the former includes 26 eruptions since the settlement, in early 15th century. The Azores Islands are formed by 16 major polygenetic volcanoes, most of them silicic and with summit subsidence calderas: nine of them are still active. Moreover, there are about 1750 monogenetic volcanoes in the archipelago, either dispersed along the flanks and inside the summit depression of the polygenetic volcanoes, either belonging to the 11 basaltic fissural volcanic systems located in different islands. These monogenetic centres include domes and coulées, tuff rings, tuff cones, maars, scoria and spatter cones, and eruptive fissures that together with other volcanic, tectonic, sedimentary, littoral and deep sea features may be considered as geosites and can embrace outstanding landscapes. B – Geological Heritage B1. Location of the proposed Geopark The Azores archipelago is located in the Atlantic Ocean, between the latitudes 36º56’ e 39º44’ North and the longitudes 24º47’ and 31º16’ West (Figure 5), and at the distance of 1815 km from the Mainland Portugal. ´ Figure 6 – General geodynamic framework of the Azores archipelago. From a geological point of view, all the Azores islands are of volcanic origin and are oceanic islands that emerged from the surrounding seafloor due to the progressively piled up of submarine volcanic products, a process that should have started about 36 million years (M.y.). -

MARINE FISHES OF THE AZORES: AN ANNOTATED CHECKLIST AND BIBLIOGRAPHY. RICARDO SERRÃO SANTOS, FILIPE MORA PORTEIRO & JOÃO PEDRO BARREIROS SANTOS, RICARDO SERRÃO, FILIPE MORA PORTEIRO & JOÃO PEDRO BARREIROS 1997. Marine fishes of the Azores: An annotated checklist and bibliography. Arquipélago. Life and Marine Sciences Supplement 1: xxiii + 242pp. Ponta Delgada. ISSN 0873-4704. ISBN 972-9340-92-7. A list of the marine fishes of the Azores is presented. The list is based on a review of the literature combined with an examination of selected specimens available from collections of Azorean fishes deposited in museums, including the collection of fish at the Department of Oceanography and Fisheries of the University of the Azores (Horta). Personal information collected over several years is also incorporated. The geographic area considered is the Economic Exclusive Zone of the Azores. The list is organised in Classes, Orders and Families according to Nelson (1994). The scientific names are, for the most part, those used in Fishes of the North-eastern Atlantic and the Mediterranean (FNAM) (Whitehead et al. 1989), and they are organised in alphabetical order within the families. Clofnam numbers (see Hureau & Monod 1979) are included for reference. Information is given if the species is not cited for the Azores in FNAM. Whenever available, vernacular names are presented, both in Portuguese (Azorean names) and in English. Synonyms, misspellings and misidentifications found in the literature in reference to the occurrence of species in the Azores are also quoted. The 460 species listed, belong to 142 families; 12 species are cited for the first time for the Azores. -

Azores and Iceland
13th World Conference on Earthquake Engineering Vancouver, B.C., Canada August 1-6, 2004 Paper No. 2369 A COMPARATIVE STUDY ON STRONG GROUND MOTION IN TWO VOLCANIC ENVIRONMENTS: AZORES AND ICELAND Carlos S. OLIVEIRA1, Ragnar SIGBJÖRNSSON2, Simon ÓLAFSSON3 SUMMARY The objective of this paper is to present the main results of a comparative study of strong ground motion on the Azores and Iceland. These islands are a super-structural part of the Mid Atlantic Ridge, which marks the boundary between the North-American Plate and the Eurasian Plate and creates a north-south oriented belt of seismic and volcanic activity. The tectonic environments are described and compared emphasising the similarities in the geological structure, including surface geology and its effects on strong ground motion. Furthermore, the seismicity of the Azores and Iceland is compared based on earthquake catalogues using statistical analysis. The strong-motion networks on the islands are described along with the strong-motion data used in the subsequent analysis. The strong-motion data are compared using statistical analysis. The main emphasis is put on attenuation of strong-motion data, characterised by root mean square acceleration and peak ground acceleration. The attenuation is also compared to some of the common attenuation relationships, used by the engineering community in Europe and America. The main findings are that there are significant similarities between the tectonic environments of the Azores and Iceland. Furthermore, the similarities found in seismicity are statistically significant. The attenuation is characterised by rapid decay with increasing distance and high acceleration in the near source area. It is found that the same ground motion estimation models can be applied on the Azores and in Iceland. -
Peopling, Demographic History and Genetic Structure of the Azores Islands: Integrating Data from Mtdna and Y-Chromosome
International Congress Series 1288 (2006) 85–87 www.ics-elsevier.com Peopling, demographic history and genetic structure of the Azores Islands: Integrating data from mtDNA and Y-chromosome Cristina Santos a,*, Rafael Montiel a, Conceic¸a˜o Bettencourt a, M. Joa˜o Prata b, Augusto Abade c, M. Pilar Aluja d, Manuela Lima a a CIRN and Department of Biology, University of the Azores, Portugal b Institute of Molecular Pathology and Immunology of the University of Porto, Portugal c Department of Anthropology, University of Coimbra, Portugal d Department of BAVE, University Autono´ma of Barcelona, Spain Abstract. We have conducted studies to assess the variability of mtDNA and Y-chromosome markers in the Azores Islands (Portugal) and found that, for both genetic systems, the Azores, as a whole, fit well into the pattern of variation described for other Western European populations. Phylogeographic analysis of mitochondrial DNA (mtDNA) showed a major contribution from Mainland Portugal, as well as evidences of influxes from Northern Europeans, Africans and Jewish groups. Characterization of markers on the non-recombining region of the Y-chromosome (NRY) has shown a main component of European lineages as well as the presence of North African chromosomes, in frequencies similar to those described for Mainland Portugal. On the other hand, both mtDNA and NRY analyses have evidenced differential demographic histories for the three groups of islands forming the archipelago. D 2005 Elsevier B.V. All rights reserved.
