Enzyme activities and glyphosate biodegradation in a riparian soil affected by simulated saltwater incursion [PDF]
, 2011 Soil salinization due to saltwater incursion, is a major threat to biochemical activities and thus strongly alters biogeochemical processes in a freshwater riparian of coastal estuary region.

Evidence of O2 consumption in underway seawater lines: Implications for air-sea O2 and CO2 fluxes [PDF]
, 2010 We observed O2 deficits of 0.5 to 2.0% (1 to 4 mol/kg) in the underway seawater lines of three different ships. Deficits in O2/Ar and isotopic enrichments in dissolved O2 observed in underway seawater lines indicate a respiratory removal process.

High-precision measurements of seawater Pb isotope compositions by double spike thermal ionization mass spectrometry [PDF]
, 2014 A new method for the determination of seawater Pb isotope compositions and concentrations was developed, which combines and optimizes previously published protocols for the separation and isotopic analysis of this element.

Fatigue crack growth rates for offshore wind monopile weldments in air and seawater: SLIC inter-laboratory test results [PDF]
, 2016 The majority of fatigue crack growth (FCG) data sets available on steels in air and seawater environments are several decades old and may not be appropriate for structural integrity assessment of offshore wind turbine foundations, which are fabricated ...

Fluorescence spectroscopy applied to the optimisation of a desalting step by electrodialysis for the characterisation of marine organic matter [PDF]
, 2008 The isolation and characterisation of marine dissolved organic matter (DOM) are still not readily achieved today. The study of this chemically complex material is particularly difficult, especially as it is hindered by the high salinity of seawater.

American Anthropologist, 2011 ABSTRACT Seawater has occupied an ambiguous place in anthropological categories of “nature” and “culture.” Seawater as nature appears as potentiality of form and uncontainable flux; it moves faster than culture—with culture frequently figured through land‐based metaphors—even as culture seeks to channel water's (nature's) flow.

Glyphosate persistence in seawater
Marine Pollution Bulletin, 2014 Glyphosate is one of the most widely applied herbicides globally but its persistence in seawater has not been reported. Here we quantify the biodegradation of glyphosate using standard "simulation" flask tests with native bacterial populations and coastal seawater from the Great Barrier Reef.

Marine aerobic biofilm as biocathode catalyst [PDF]
, 2010 Stainless steel electrodes were immersed in open seawater and polarized for some days at − 200 mV vs. Ag/AgCl. The current increase indicated the formation of biofilms that catalysed the electrochemical reduction of oxygen.

Temperature influence on the carbon isotopic composition of Orbulina universa and Globigerina bulloides (planktonic foraminifera) [PDF]
, 2000 Laboratory experiments with the planktonic foraminifera Orbulina universa (symbiotic) and Globigerina bulloides (nonsymbiotic) were used to examine the effects of temperature, irradiance (symbiont photosynthesis), [CO32-], [HPO42-], and ontogeny on shell

Turning on the heat: ecological response to simulated warming in the sea [PDF]
, 2010 Significant warming has been observed in every ocean, yet our ability to predict the consequences of oceanic warming on marine biodiversity remains poor.
