Simulation of the 2004 tsunami of Les Saintes in Guadeloupe (Lesser Antilles)

This report supplements an earlier account on the hydroids of the Guadeloupe archipelago, and records 31 additional species of thecates. Among them, Halecium calderi sp. nov., Antennella armata sp. nov., and Antennella incerta sp. nov., are described. Laomedea tottoni Leloup, 1935 is redescribed and reassigned to the genus Clytia Lamouroux, 1812. Its synonymy is broadened upon inclusion of Clytia laxa Fraser, 1937. Hebella venusta (Allman, 1877) is considered valid based on comparison with related species, and its gonotheca is described for the first time. Two sympatric varieties of Sertularella diaphana (Allman, 1885), easily separable morphologically and by their cnidome composition, are discussed. Sertularella ornata Fraser, 1937 is recorded for the second time and is fully redescribed. Its name is actually a junior synonym of S. fusiformis (Hincks, 1861) f. ornata Broch, 1933, and it is here referred to as S. fraseri nom. nov. Sertularia thecocarpa Jarvis, 1922, Sertularella minuscula Billard, 1924, Sertularella parvula Mammen, 1965, and Sertularia stechowi Hirohito, 1995 are placed in the synonymy of Sertularella tongensis Stechow, 1919, the latter being transferred to the genus Sertularia Linnaeus, 1758. Sertularia ephemera nom. nov. is proposed as a replacement name for Sertularia tongensis Stechow, 1919. Aglaophenia postdentata Billard, 1913 is confidently recorded from the Atlantic for the first time. Dentitheca dendritica (Nutting, 1900) is redescribed, and additional notes on Macrorhynchia clarkei (Nutting, 1900) are provided. All the species discussed herein are new records for the study area. Illustrations are given for each species and data on the nematocyst complement and size of capsules are given when necessary. The number of hydroid species reported from the study area is raised to more than eighty. Hydroids of the Caribbean are moderately well known faunistically, though continuous discovery of new species is likely, the species composition being certainly richer than currently reported.

Abstract In this paper, we provide the first structural map of Les Saintes archipelago (Guadeloupe, Lesser Antilles). The finite strain pattern displays four families of fault systems characterized by their statistical structural orientations: N000-N020, N050-N070, N090-N110 and N130-N140 trending fault systems. Our onshore results thus underline a fault network much more complex than the one depicted by the previous offshore geophysical investigations around Les Saintes archipelago, which show only N120-N150 trending system. According to the available K-Ar dating of the volcanic rocks and the relative chronology of the faults defined in the field, we determine the deformation history in Les Saintes islands since the last 3 Ma. The four highlighted trending fault systems are already active since the Pliocene and are consistent with the present-day extensional tectonics in the Guadeloupe archipelago compatible with the reactivation of inherited structures at the active arc scale. We interpret the tectonic evolution of Les Saintes islands as the result of interplay between subduction of aseismic ridges (Tiburon and Barracuda ridges) and oblique convergence. Furthermore, we recognized an exhumed geothermal paleo-system in Terre-de-Haut island which is a good analogue of the present-day active Bouillante geothermal system. Its duration is estimated at 400 k.y. during the Pliocene.

Les Saintes

A recent collection of shallow-water hydroids from Guadeloupe and Les Saintes, in the eastern Caribbean Sea, was studied. This is the first comprehensive report on the hydroid fauna from the study area. A total of 48 species, belonging to 9 families of athecates and 12 families of thecates, are described or listed. All the species are illustrated and, when necessary, data on the cnidome composition are provided. Two new species, Zanclea migottoi sp. nov. and Halopteris vervoorti sp. nov., are described. Rhizogeton sterreri (Calder, 1988) is redescribed based on fertile material. Its taxonomic status is discussed and the genus Rhizodendrium Calder, 1988 is included in the synonymy of Rhizogeton L. Agassiz, 1862. Scandia michaelsarsi (Leloup, 1935) is believed to be a synonym of S. gigas (Pieper, 1884), and morphological arguments are provided to support this hypothesis. An undescribed type of peculiar gonothecae, arising from the hydrothecal apertures, was found in Dynamena disticha (Bosc, 1802). Sertularella peculiaris (Leloup, 1935) is redescribed and its synonymy discussed. The nematocyst types of Symmetroscyphus intermedius (Congdon, 1907) were identified. Some species in the present collection are provisionally identified or assigned to a genus, pending the discovery of fertile material or additional life cycle studies. Finally, the hydroid fauna from the study area proves to be preponderantly tropical in nature, with several species also occurring in temperate seas. A number of species are first records for the Caribbean basin: R. sterreri, Eudendrium capillare Alder, 1856, Coryne pusilla Gaertner, 1774, Halecium cf. lankesteri (Bourne, 1890), S. gigas, and Sertularia loculosa Busk, 1852.
