Evaluating land–sea linkages using land cover change and coral reef monitoring data: A case study from northeastern Puerto Rico

Remote Sensing in Ecology and Conservation, EarlyView.
Land cover change that leads to increased nutrient and sediment runoff is an important driver of change in coral reef ecosystems. In this study, we combined satellite remote sensing and field monitoring to assess concomitant changes in watershed land cover and coral cover in northeastern Puerto Rico in 2000–2015.

Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review

SmartBot, EarlyView.
Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

Micronuclei and Other Nuclear Abnormalities in Patella Limpet as Biomarkers of Cytogenotoxicity in Recreational Port Waters

Environmental Toxicology, EarlyView.
ABSTRACT Over the past decades, the growth in human population and economic activities has led to an increase in maritime traffic. This rise puts additional pressure on marine environments, vessel fuel spills being considered to have a major impact on the ecosystem.

PM2.5 Chemical Composition and Geographic Origin of Air Masses in Mabopane, South Africa

X-Ray Spectrometry, EarlyView.
ABSTRACT Air pollution is a major global threat to health. The study aimed to analyze the chemical composition of PM2.5 in Mabopane, South Africa, and to identify the contribution of transported particulate pollution sources using backward air transport cluster analysis.

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Ophiolites found in oceanic crust?

Geophysical Research Letters, 1978
We have demonstrated that a seismic solution to a set of ocean crustal P and S wave data from the Guadalupe Island area is consistent with measured P and S velocity samples from the Bay of Islands Ophiolite Suite and the observed stratigraphy. The seismic model (SOD‐1), derived separately for the P and S wave propagation, contains no major interfaces ...

M. E. Grant Duff, Philosophic Liberalism and the Global Liberal Cause

History, EarlyView.
Abstract Historians disagree about how best to conceptualize nineteenth‐century British Liberalism in relation to its international contexts. This article argues that we can better understand the patterns involved by interrogating individuals who bridged the worlds of partisan politics and elaborated thought.

Increased metamorphic conditions in the lower crust during oceanic transform fault evolution [PDF]

Solid Earth
Oceanic transform faults connect the segments of active spreading ridges that slide past each other. In a classical view, transform faults are considered conservative, where no material is added or destroyed.

Oceanic crust deep seismic survey

Eos, Transactions American Geophysical Union, 1992
In September 1991, the British Institutions Reflection Profiling Syndicate (BIRPS) collected 578 km of deep seismic reflection profiles over the oceanic crust beneath the Cape Verde abssyal plain in approximately 4900 m of water (Fig. 1). The survey, under the direction of J. H. McBride, was undertaken in response to a proposal made by R. S.

Palaeoenvironmental evolution of the Baltic Sea basin during the Last Interglacial (Eemian, Mikulino stages): a review

Boreas, EarlyView.
This review presents an investigation of the evolution of the Baltic Sea basin and its connections through the Eemian Stage, based upon sequences of marine and associated deposits from the White Sea to the Southwest Baltic, via the Karelian channel. Pollen analyses, foraminiferal and ostracod analyses provide the evolution of relative sea‐level change,
