Introduction: The martian highlands preserve a long and complex history of degradation by fluvial, eolian, and mass wasting processes [1-8]. The effects of these processes are best observed on impact craters that characterize the ancient highlands. Previous studies of highland terrains Margaritifer Sinus [9,10], Ismenius Lacus [11,12], Arabia Terra [13], and Promethei Terra [14,15] have shown t...

The reemerging field of Medical Geology is concerned with the impacts of geologic materials and geologic processes on animal and human health. Most medical geology research has been focused on health problems caused by excess or deficiency of trace elements, exposure to ambient dust, and on other geologically related health problems or health problems for which geoscience tools, techniques, or ...

Biogeosciences Discussions This discussion paper is/has been under review for the journal Biogeosciences (BG). Please refer to the corresponding final paper in BG if available. Abstract We present a new geologic-time and basin-spatial scale model of the continental margin methane cycle. The model, SpongeBOB, is used to simulate evolution of the carbon cycle in a passive sedimentary continental ...

The sediments of the North Atlantic north of 45°N do not seem to have attracted widespread attention prior to 1940, when Bramlette and Bradley published the results of their studies of cores obtained between Ireland and Newfoundland by the cable ship Lord Kelvin (Bramlette and Bradley, 1940). Since that time, however, a wealth of information concerning the sediments of this region has been gath...

As a participant of the ONR Shallow Water Acoustics experiment to be held on the outer New Jersey shelf during the summer of 2006 (SWA06), the long term goal of this project is to understand the interaction of acoustic energy, at both medium and low frequencies, with the seabed. OBJECTIVES The objectives of this work are to (1) incorporate existing geological, geophysical and geoacoustic data i...

Modern ground-water flow models, geotechnical studies, and science-based land-use planning require knowledge of the distribution of surficial earth materials from land surface to the top of bedrock (e.g., Masterson and others, 1997a,). To be useful, modern geologic maps must portray such information three dimensionally in a way that is consistent with the regional stratigraphic framework, geote...

The Paleozoic volcano-sedimentary rocks within the structural basement of horst-and-graben system Catalan Coastal Ranges (CCR) are composed black shale, volcaniclastic sediments, lava flows, sills and lithocrystalloclastic tuffs. sediments depleted in high-field strength elements (HFSE) such as Nb, Ta, Zr, Hf Ti, suggesting their accumulation Andean-type active continental margin environment. V...

A geologic map is a fundamental scientific tool that shows the distribution of geologic material. This study used data gathered at Seven Mile Creek Park to make a geologic map. This data examines the relationships between ravine cutting, terrace development, and base level in a tributary to the Minnesota River, known as Seven Mile Creek. Within the Park there is an extensive network of ravines ...

Marine sediment with an input of particulate organic matter was incubated to simulate the early aging process. On the sediment after various incubation periods, adsorption and desorption tests were conducted for three selected organic micropollutants: bisphenol A (BPA), 17α-ethinyl estradiol (EE2), and phenanthrene (Phe). The results showed significant sediment organic matter (SOM) decompositio...
