Mass spectrometric in the analysis of inorganic substances Mass spectrometric in the analysis of inorganic substances

Mass spectrometry is an analytical technique used to measure the composition of a substance by isolating specific analyte components according to their individual atomic or molecular mass‐to‐charge ratios. Inorganic mass spectrometry is specifically used to determine the elemental and isotopic composition of the material being analyzed. The techniques are capable of the measurement of a...

The impact of invasive plants on tidal-marsh vertebrate species: common reed (Phragmites australis) and smooth cordgrass (Spartina alterniflora) as case studies The impact of invasive plants on tidal-marsh vertebrate species: common reed (Phragmites australis) and smooth cordgrass (Spartina alterniflora) as case studies

Large areas of tidal marsh in the contiguous US and the Maritime Provinces of Canada are threatened by invasive plant species. Our understanding of the impact these invasions have on tidal-marsh vertebrates is sparse. In this paper, we focus on two successful invasive plant taxa that have spread outside their native range --common reed (Phragmites australis) and smooth cordgrass...

An overview of the global variability in radiated energy and apparent stress An overview of the global variability in radiated energy and apparent stress

a global study of radiated seismic energies ER and apparent stresses τ a reveals systematic patterns. earthquakes with the highest apparent stress occur in regions of intense deformation and rupture strong lithosphere. in oceanic settings, these are strike-slip earthquakes (τ a up to 27 Mpa) occurring intraplate or at evolving ends of transform faults. at subduction zones and...

Multimodeling: new approaches for linking ecological models Multimodeling: new approaches for linking ecological models

The Everglades region of South Florida presents one of the major natural system management challenges facing the United States. With its assortment of alligators, crocodiles, manatees, panthers, large mixed flocks of wading birds, highly diverse subtropical flora, and sea of sawgrass, the ecosystem is unique in this country (Davis and Ogden 1994). The region is also perhaps the largest...

Scouting craton’s edge in Paleo-Pacific Gondwana Scouting craton’s edge in Paleo-Pacific Gondwana

The geology of the ice-covered interior of the East Antarctic shield is completely unknown; inferences about its composition and history are based on extrapolating scant outcrops from the coast inland. Although the shield is clearly composite in nature, a large part of its interior has been represented by a single Precambrian block, termed the Mawson block, that includes the Archean

ADMAP: A Digital Magnetic Anomaly Map of the Antarctic ADMAP: A Digital Magnetic Anomaly Map of the Antarctic

For a number of years the multi-national ADMAP working group has been compiling near surface and satellite magnetic data in the region south of 60° S. By the end of 2000, a 5 km grid of magnetic anomalies was produced for the entire region. The map readily portrays the first-order magnetic differences between oceanic and continental regions. The magnetic anomaly pattern over the...

Integration of coral reef ecosystem process studies and remote sensing Integration of coral reef ecosystem process studies and remote sensing

Worldwide, local-scale anthropogenic stress combined with global climate change is driving shifts in the state of reef benthic communities from coral-rich to micro- or macroalgal-dominated (Knowlton, 1992; Done, 1999). Such phase shifts in reef benthic communities may be either abrupt or gradual, and case studies from diverse ocean basins demonstrate that recovery, while uncertain...
