Ferð til Galapagos eyja
… fjallar um skipulagningu á ferð frá Íslandi til Galapagos eyja fyrir lítinn hóp ferðamanna. Viðskiptaáætlunin sjálf hefur að geyma viðskiptahugmyndina, greiningu á markaðnum og markhópnum ásamt kosntaðar- og áhættugreiningu ferðarinnar. Skýrslan greinir Galapagos eyjar sem áfangastað. Fjallað er …

Geothermal processes at the Galapagos Spreading Center
The measurements of the heat flow field of the Galapagos Spreading Center in an area of about 570 km2 reveal the planform of the conductive flux and permit the first truly areal estimate of the near-axis heat flux for comparison with theoretical plate cooling models. The intrusion process and …

Seasonal variation in population location of the Galapagos tortoise, geochelone elephantopus vandenburghi, on Volcan Alcedo, Isabela Island, Galapagos archipelago
<p>Twenty tortoises, 10 adult males and 10 adult females, were tagged with radio transmitters. Numbers were painted on each carapace to aid in visual sighting. The tortoises were released, and their movement was monitored over a one year period.</p> <p>The percent recovery of tagged tortoises along …

Marine Invasive Species in the Galapagos Marine Reserve
… non-native species are the number one threat to Galapagos ecosystems and although many preventive and corrective measures have been applied to terrestrial problems, the impacts of invasive non-native species in the marine environment has received relatively little attention to date. The marine …

Analysis of biomarker candidates from plant lipid inputs into Galapagos lacustrine sediments
… Junco lake catchmernt on Sari Cristobal in the Galapagos Islands were solvent extracted, identified and quantified using gas chromatography arid mass spectrometry. The analysis revealed evidence for significant aquatic and terrestrial vascular plant inputs to lake sediments. High concentrations …

Neuro-Fuzzy Classification of Submarine Lava Flow Morphology On the Galapagos Spreading Center, 92W
<p>Submarine volcanism at mid-ocean ridges (MORs) comprises the majority of global magmatism and produces the quantum units of the upper oceanic crust, which covers over 70% of Earth's surface. Despite being one of our planet's most prolific and ubiquitous processes, only two deep seafloor …

The impact of the Galapagos Islands on the dynamics of the equatorial East Pacific
… the equator of a medium-sized island group - the Galapagos Archipelago. The project is carried through using a combination of: in situ oceanographic data from ships and moorings; satellite SST and colour images; and diagnostics from both a sophisticated ocean general circulation model and a …

The Evolution of the Galapagos Mantle Plume: From Large Igneous Province to Ocean Island Basalt
Mantle plumes are anomalously hot, narrow upwellings of mantle material that originate at the core-mantle boundary. As plumes rise they may form volumetrically large "heads" (~1000 km in diameter) with narrower (~100 km) "tails." Plume head melting is thought to form Large Igneous Provinces (LIPs), …

Precipitation amount, altitude, and moisture trajectory effects on the stable isotopic composition of precipitation in the Galapagos Islands
Understanding how climate processes facilitate stable water isotope variability in precipitation over time and space is critical to interpreting stable isotope-based paleoclimate proxies, particularly in the eastern equatorial Pacific where stable water isotope observations from precipitation …

Mantle plume-midocean ridge interaction : geophysical observations and mantle dynamics
… dimensions, and fluxes of the Icelandic and Galapagos plumes. In Chapter 1 we analyze bathymetric and gravity anomalies along the hotspot-influenced Galapagos Spreading Center. We find that the Galapagos plume generates along-axis bathymetric and mantle-Bouguer gravity anomalies (MBA) that …

Evolution in Neotropical Herpetofauna: Species Boundaries in High Andean Frogs and Evolutionary Genetics in the Lava Lizard Genus Microlophus (Squamata: tropiduridae): A History of Colonization and Dispersal
… of my dissertation work. The genus includes both Galapagos insular species, and continental taxa distributed in a linear gradient along > 4000 km of the western coast of South America. In studying Microlophus I first tackled the unresolved phylogenetic relationships within the genus (Chapter 3) …

Something Like Human
… war humanity have relocated to colonies on the Galapagos Islands. The novel follows the young daughter of a metalworker, Kyra Krikorian, as she befriends a squid boy, who she names OctoBoy. Concurrently, the novel explores her adulthood and the ramifications of this friendship, including her …

Evaluating mantle and crustal processes using isotope geochemistry
… composition and He, Sr, Nd and Pb isotopes of Galapagos lavas indicates that magma mixing between plume and asthenospheric melts has been the main process responsible for the geochemical variation observed in the archipelago. Correlations between He isotopes and TilTi*, K/Rb and Nb/La ratios …

Mapping the Core-Mantle Boundary Using Sdiff Postcursors
… of major hotspots (Hawaii, Iceland, Samoa, and Galapagos), and have been suggested to act as a plume root and geochemical reservoir. In this thesis, we use the S core-diffracted phase (Sdiff) to detect ULVZs. Sdiff wavefronts propagating across the core-mantle boundary refract through low …

Wrangell Island: From political conflict to Russian sovereignty
… other World Heritage Site islands such as the Galapagos, Aldabra and Heard Island. This would facilitate conclusion of a Treaty with the United States Government which would thence annul any basis for contention over sovereignty, thus confirming the <i>de jure</i> rights of Russia.

Oblique Seafloor Spreading, the Malpelo Plate Hypothesis, and Cocos-Nazca-Pacific Plate Motion Circuit
… defined Cocos-Nazca plate boundary east of the Galapagos transform fault, the non-closure velocity is reduced to 4.2 mm a–1 ±3.8 mm a–1 (95% confidence limits), which is insignificant. This result indicates that the plate boundary east of the Galapagos Transform Fault does not record motion …

Horizontal gene transfer as a cohesive force in microbial populations
