Macrofaunal assemblages from mud volcanoes in the Gulf of Cadiz

Desde a descoberta em 1999 do primeiro vulcão de lama no Golfo de Cádis, cerca de 40 locais, de profundidade variável entre os 200 e os 3900 m, com diferentes graus de emissão de hidrocarbonetos foram localizados e amostrados dentro do programa IOC-UNESCO “Training Through Research (TTR) “ e mais recentemente dentro do projecto europeu HERMES. Neste estudo investigamos as comunidades da macrofauna dos vulcões de lama do Golfo de Cádis utilizando uma diversidade de equipamento de amostragem quantitativo e não quantitativo. Mais de 14550 espécimes foram examinados e incluídos nos diferentes grupos taxonómicos, sendo fornecida uma lista taxonómica detalhada com o menor nível taxonómico possível. A biodiversidade, distribuição dos principais taxa, as espécies quimiossintéticas e a biodiversidade regional e substituição de espécies são apresentados e discutidos. Dentro da macrofauna, os bivalves (nomeadamente super-familia Thyasiroidea, espécies quimisimbióticos e comunidade de bivalves) e os ofiurideos são estudados em pormenor. Os Thyasiroidea colhidos nos vulcões de lama do Golfo de Cádis são revistos. Das sete espécies identificadas, apenas uma Thyasira vulcolutre. sp. nov se encontra associada a um ambiente quimiossintético. Esta espécie é restrita a locais activos, mas não se verificam padrões de distribuição para as outras espécies. Os bivalves quimiosimbióticos amostrados são revistos. Das 10 espécies fortemente associadas a ambientes quimiossintéticos duas Solemyidae, Petrasma elarraichensis sp. nov. e Acharax gadirae sp. nov., uma Lucinidae, Lucinoma asapheus sp. nov., e uma Vesicomyidae, Isorropodon megadesmus sp. nov. são descritas e comparadas com similares das respectivas famílias. As comunidades de bivalves foram analisadas em detalhe e do estudo de 759 espécimes (49 espécies em 21 familias) descreve-se a diversidade e padrões de distribuição. Os Ophiuroidea amostrados nos vulcões de lama e ambientes batiais adjacentes são revistos. Treze espécies são incluídas em 4 famílias, Ophiacanthidae, Ophiactidae, Amphiuridae e Ophiuridae e são identificadas, tendo sido descrita uma nova espécie Ophiopristis cadiza sp. nov. Rácios isotópicos (δ13C, δ15N, δ34S) foram determinados em várias espécies no intuito de investigar a ecologia trófica das comunidades bênticas dos vulcões do Golfo de Cádis. Os valores de δ13C para os bivalves Solemyidae, Lucinidae e Thyasiridae estão de acordo com os valores para outros bivalves conhecidos por possuírem simbiontes tiotróficos. Por outro lado os valores de δ13C e δ34S para Bathymodiolus mauritanicus sugerem a ocorrência de metanotrofia. A análise da fauna heterotrófica indica igualmente que as espécies habitantes da cratera dos vulcões de lama derivam a sua nutrição de fontes quimiossintéticas. A indicação pela análise isotópica que as bactérias autotróficas contribuem substancialmente para a nutrição dos bivalves hospedeiros, levou-nos a investigar os endossimbiontes e as suas relações filogenéticas relativamente a outros bivalves através da análise comparativa de análises de sequências de 16S ribossomal RNS. Análises moleculares PCR-DGGE (Denaturing Gradient Gel Electrophoresis) e clonagem de genes de bacterias 16S rRNA confirmaram a presença de simbiontes oxidantes de enxofre e colocam a possibilidade de uma simbiose dupla para o B. mauritanicus. A diversidade microbiana dentro dos Frenulata foi igualmente estudada recorrendo a métodos moleculares e revelou a não existência de padrão entre espécies, vulcões, profundidade e idade do animal sugerindo assim a não procura de simbiontes específicos.

The Church of the Abandoned Christ: David Peace's 'Red Riding Quartet' and the Wreck of the White Ship

David Peace’s novel Nineteen Seventy-seven concludes with the hack journalist Jack Whitehead being granted a terrifying apocalyptic vision, seconds before he is trepanned with a Phillips screwdriver by the sinister Reverend Martin Laws. Included in this vision is a curious reference to the wreck of the White Ship, a maritime disaster in 1120 that drowned William Atheling, heir to the English throne, and ultimately doomed England to years of civil war. This article explores Peace’s strange use of the shipwreck in his “Red Riding Quartet,” particularly the way he links it—in the quartet’s final volume, Nineteen Eighty Three—to a revisionist account of the aftermath of the crucifixion that leads a wounded Christ to a tragic death in the cold waters of the English Channel.

Genetic algorithm for shipping route estimation with long-range tracking data : automatic reconstruction of shipping routes based on the historical ship positions for maritime safety applications

Ship tracking systems allow Maritime Organizations that are concerned with the Safety at Sea to obtain information on the current location and route of merchant vessels. Thanks to Space technology in recent years the geographical coverage of the ship tracking platforms has increased significantly, from radar based near-shore traffic monitoring towards a worldwide picture of the maritime traffic situation. The long-range tracking systems currently in operations allow the storage of ship position data over many years: a valuable source of knowledge about the shipping routes between different ocean regions. The outcome of this Master project is a software prototype for the estimation of the most operated shipping route between any two geographical locations. The analysis is based on the historical ship positions acquired with long-range tracking systems. The proposed approach makes use of a Genetic Algorithm applied on a training set of relevant ship positions extracted from the long-term storage tracking database of the European Maritime Safety Agency (EMSA). The analysis of some representative shipping routes is presented and the quality of the results and their operational applications are assessed by a Maritime Safety expert.

Ship canal. Ottawa versus the Trent. [letter], 1863.

One published letter addressed to the Hon. Sidney Smith, M.L.C., Quebec from W.S. Conger, dated April 6, 1863, Peterborough. The headline reads: Ship Canal. Ottawa versus the Trent. This letter contains reprinted portions of a letter that W.S. Conger wrote in March 1858 to the Hon. Charles Alleyn, then Commissioner of Public Works.

John O. McKellar (ship) certificates, 1952-1983.

The John O. McKellar was a ship that belonged to the Scott Misener fleet. The first ship named after McKellar was launched on Januaray 25, 1929, from Wallsend, England, and was bound for Sault St. Marie, Ontario. This ship became part of the Colonial Steamship Company in 1950, and in 1952 was renamed the J.G. Irwin when construction of a new John O. McKellar was completed. John Oscar McKellar was born on June 28, 1878 in Lobo Township, Middlesex County, west of London, Ont. He worked as a marine engineer, and became acquainted with Robert Scott Misener when the two were shipmates serving with the Algoma central fleet. In 1919, the two men joined forces to run a shipping company. Together, they purchased the wooden steamer "Simon Langell", and worked together on the ship for the next three years. Throughout his career with Misener's company, John McKellar served as Chief Engineer, then Marine Superintendent, and finally Secretary-Treasurer. He died on September 19, 1951.
