Introduction and Background: One of the most fundamental questions in the geological and thermal evolution of the Moon is the nature and history of mantle melting and its relationship to the formation and evolution of lunar multi-ringed basins. Mare volcanic deposits provide evidence for the nature, magnitude and composition of mantle melting as a function of space and time [1]. Many argue that...

We present an integrated method for mapping the basement structures of sedimentary basins by combining surface gravity data, seismic imaging, and borehole logging information. The core is a nonlinear inversion algorithm constructing shape depth from data. By using primal-logarithmic barrier method, we impose constraints was imaged interpretation incorporated into as reference model. As result, ...

The Mediterranean Sea is a marine biodiversity hot spot. Here we combined an extensive literature analysis with expert opinions to update publicly available estimates of major taxa in this marine ecosystem and to revise and update several species lists. We also assessed overall spatial and temporal patterns of species diversity and identified major changes and threats. Our results listed approx...

The campaign of opposition to MX missile deployment in the Great Basin of Nevada and Utah stands as a unique case of grassroots mobilization, because it took place in a region whose inhabitants both supported a strong U.S. military defense posture and considered the decision-making processes of foreign policy and national security remote to their overall concerns. This study holds that the two ...

Accelerated degradation of the wetlands and fragmentation of surrounding vegetation in the Andean-Orinoco Piedmont are the main threats to diversity and ecological integrity of these ecosystems; however, information on this topic is of limited availability. In this region, we evaluated the value of 37 lentic wetlands as reservoirs of woody and aquatic plants and analyzed diversity and changes i...

The Mar Piccolo basin is an internal sea basin located along the Ionian coast (Southern Italy), and it is surrounded primarily by fractured carbonate karstic environment. Because of the karstic features, the main continental water inflow is from groundwater discharge. The Mar Piccolo basin represents a peculiar and sensitive environment and a social emergency because of sea water and sediment p...

Based on easily available morphological data within the Seine river watershed (76750 km(2)), two approaches were used for wetland delineation and characterisation. Their common assumption is that geomorphology largely governs the spatial distribution of wetlands, because it determines topography and the nature of deposits, thus water pathways and residence times. The first approach relies on th...

The Laurentian Great Lakes Basin provides an ecological system to evaluate the potential effect of climate change on dynamics of fish populations and the management of their fisheries. This review describes the physical and biological mechanisms by which fish populations will be affected by changes in timing and duration of ice cover, precipitation events and temperature regimes associated with...

This thesis is composed of three Chapters. Chapter 1 is a preface that outlines the degree program and components of my thesis. Chapter 2 is the main body of the thesis; it is an investigation into pore pressures in the Auger basin and how they are related to fluid venting at the seafloor. I map the distribution of subsurface pressures in thick interconnected sand bodies that are present across...
