Abstract:

Hydrothermal vents and their associated fauna were first discovered in 1977. An unusual, diverse fauna thrives around these vents. The dynamic and unpredictable nature of volcanism, fluid chemistry and temperature around vents mean these faunal habitats remain for a maximum of -20 years. This study examines fossilisation of vent fauna from five localities of varying tectonic setting and age: the Mothra Vent Field, Endeavour Segment, Juan de Fuca Ridge; 'Feather Duster' vent site, 11oN East Pacific Rise; 'MESO' zone, Central Indian Ridge; Roman Ruins vent site, PACMANUS, eastern Manus Basin; an

Abstract:

Hydrothermal ventfauna, particularly vestimentiferan and polychaete worm tubes, are occasionally preserved in the geological record. The early stages of mineralisation are particularly important in defining whether or not preservation will occur, and they are poorly understood. This dissertation describes 3 separate studies of ventfauna undergoing early mineralisation associated with active seafloor vent systems. Tube samples of the polychaete worm Alvinella pompejana collected from 13°N on the East Pacific Rise were studied to identify the processes occurring during early sulphide mineralisat

Abstract:

This thesis presents two families of novel algorithms for automated planning under uncertainty. It focuses on the domain of searching the ocean floor for hydrothermal vents, using autonomous underwater vehicles (AUVs). This is a hard problem because the AUV's sensors cannot directly measure the range or bearing to vents, but instead detecting the plume from a vent indicates the source vent lies somewhere up-current, within a relatively large swathe of the search area. An unknown number of vents may be located anywhere in the search area, giving rise to a problem that is naturally formulated as

Abstract:

Hydrothermal vents (HV) are deep-sea ecosystems where hypoxia/anoxia is one of the major constraints. Respiratory pigments play a key function in the adaptation to hypoxia. HV polynoids are abundant, diverse and widely distributed and are the only ones to possess hemoglobins (Hb), and these are unique among annelids. The goal of this work was to know their evolutionary history. There are 2 types of Hb in HV polynoids: 1- and 4-domains. While they are extracellular, they are more related to intracellular globins that to annelid extracellular ones, indicating a distinct origin. We studied the ev

Symbioses between prokaryotes and eukaryotes are ubiquitous in our biosphere, nevertheless, the effects of such associations on the partners' ecology and evolution are poorly understood. At hydrothermal vents, dominant invertebrate species typically host bacterial symbionts, which use chemical energy to fix carbon to nourish their hosts and themselves. In this dissertation, I present evidence that symbiont metabolism plays a substantive, if not major, role in habitat use by vent symbioses.

Hydrothermal vent ecosystems are defined by steep thermal and chemical gradients.

However, our understanding of how abiotic factors such as temperature, geochemistry, and mineral substrate influence the activity of these microbes is limited.

However, the distributional patterns of the microorganisms that colonize deep-sea hydrothermal vent deposits and their link to the geologic setting are still not deeply understood.

The Taupo Volcanic Zone (TVZ) is an area of extensive volcanism and geothermal activity in the North Island of New Zealand. The Calypso Hydrothermal Vent Field (CHVF) is located in an offshore extension of the TVZ on continental shelf, approximately 10 km southwest of the White Island subaerial volcano, at 180-200 m water depth in the Bay of Plenty, New Zealand. Active, moderate temperature (up to 201°C) hydrothermal venting is contained within the Whakatane Graben, a northeast trending depression that has been partially filled by tephra from regional, subaerial volcanic eruptions.

Abstract:

Les écosystèmes hydrothermaux profonds sont des oasis de vie denses où la production primaire est dépendante de la chimiosynthèse réalisée par des microorganismes, dont certains forment des symbioses avec les taxons hydrothermaux dominants.Dans cet habitat éphémère et fragmenté, ces organismes endémiques font face à un double défi : disperser à travers un environnement très différent du biotope hydrothermal, et maintenir l’association symbiotique essentielle à la colonisation de ce milieu.Les crevettes du genre Rimicaris dominent les communautés des sites hydrothermaux profonds de la ride médi
