The 1963–1967 shallow-to-emergent eruption in Iceland’s Vestmannaeyjar earned a place the history of volcanology by creating island Surtsey while under close observation volcanologist Sigurdur Thorarinsson (Sigurður Þórarinsson Icelandic). This is an example what now called Surtseyan volcanism, and it included explosive effusive phases from multiple vents that formed itself, as well one fully s...

Key to this dis cov ery was the rec og ni tion of a group of Palaeozoic, sub ma rine vol ca nic rocks, named the Mount Attree volcanics, which had pre vi ously been mapped as part of the Lower Ju ras sic Telkwa For ma tion (Woodsworth et al., 1985). The Lower Telkwa vol ca nic rocks are not con sid ered pro spec tive for VHMS de pos its be cause they formed in a subaerial, compressional en vi r...

The 1285 m thick MIS core offers an invaluable opportunity to obtain a detailed record of volcanism in McMurdo Sound. Volcanic stratigraphy and preliminary petrologic data on volcanic rocks in the AND-1B core are reported here. Remarkable volcanic deposits include: a) a phonolitic pumice layer found at ≈85 mbsf which is not correlated to any known vent onshore; b) a black well sorted volcanic s...

An inventory of the weevil fauna of Mona Island, Puerto Rico, is provided. Sixteen new records and 5-9 new species are reported, yielding a total of 28 species of Curculionoidea for the island. The distribution and natural history of each species are briefly reviewed. As many as nine species are endemics, whereas 15 species are shared with Puerto Rico which was the primary source region for Pli...

The Watanabea clade of the Trebouxiophyceae included mostly unicellular coccoid microalgae that thrived in various terrestrial microhabitats. The diversity of these morphologically uniform microalgae was little known, and several new genus-level lineages had recently been described on the basis of molecular data. In this study, we provided a taxonomic description of a new trebouxiophycean genus...

The algal flora of subaerial habitats in the tropics remains largely unexplored, despite the fact that it potentially encompasses a wealth of new evolutionary diversity. Here we present a detailed morphological and molecular characterization of an autosporic coccoid green alga isolated from decaying wood in a natural forest in Singapore. Depending on culture conditions, this alga formed globula...

This paper presents a new numerical model simulating tsunamis generation by landslides. Water, air, and the slide (considered either as a viscous fluid or as a rigid bloc using the penalization method) are described by Navier-Stokes equations, expressed in a unified single fluid approach. The PLIC-VOF method is used to describe the motion of fluid interfaces. We present results for two test cas...
