Limnology and Oceanography: Methods, EarlyView.Abstract Metabolism is a key property of lake ecosystem functioning, but logistical challenges make it difficult to estimate across remote regions. The steady‐state dissolved oxygen (DO) stable isotope method (18O method) estimates metabolism from discrete water samples and thus enables large‐scale surveys.

Evidence of Titan's Climate History from Evaporite Distribution
, 2014 Water-ice-poor, 5-$\mu$m-bright material on Saturn's moon Titan has previously been geomorphologically identified as evaporitic. Here we present a global distribution of the occurrences of the 5-$\mu$m-bright spectral unit, identified with Cassini's ...

Limnology and Oceanography: Methods, EarlyView.Abstract Understanding a population's distribution depends on observing the presence and movement of individuals throughout their range. For highly mobile marine species, these observations typically rely on high effort monitoring programs. Tracking enough individuals to understand trends in movement behavior is not always logistically feasible, and ...

Spatial–Temporal Characterization of Microplastics in the Surface Water of an Urban Ephemeral River
MicroplasticsRivers are recognized as major unilateral pathways of microplastic transport between terrestrial and marine ecosystems, yet our understanding of their dispersal patterns over space and through time as they migrate from source to sink is limited.

Lipid correction of hydrogen stable isotope ratios in fish
Limnology and Oceanography: Methods, EarlyView.Abstract Lipids are known to affect stable isotope ratio of organisms, especially δ13C values, and simple arithmetic lipid‐correction procedures have been developed based on the carbon to nitrogen ratio (C : N) that is a proxy for lipid content. Equivalent issues will likely arise with the increasing use of hydrogen isotopes in ecology, but as yet no ...

Limnology and Oceanography: Methods, EarlyView.Abstract Accurate direct measurements of coccolithophore particulate inorganic and organic carbon ratios (PIC/POC) are crucial for understanding the physiology and role these microbes play in global ocean carbon flux. Direct measurements of POC are commonly obtained by acid fuming or applying acid directly to filters to dissolve PIC (CaCO3) prior to CN

Possible origin of some channels on Alba Patera, Mars [PDF]
Several alternative models were proposed for the origin and mode of formation of channels and valley networks on Martian volcanoes, notably Hecates Tholus, Ceraunius Tholus, and Alba Patera.

New evidence on palaeoenvironmental conditions in SW Cameroon since the Late Pleistocene derived from alluvial sediments of the Ntem River [PDF]
, 2010 An interior delta in the lower course of the Ntem River near the sub-prefecture Ma’an was identified after interpretation of satellite images, topographical maps of SW Cameroon and geological as well as hydrological references and a reconnaissance ...

Limnology and Oceanography: Methods, EarlyView.Abstract Particles sinking from the surface to the deep ocean play a key role in the biological carbon pump, whose efficiency depends partly on sinking velocities. Over the last decade, in situ imaging has enabled critical advances in our understanding of particle dynamics in the ocean.
