Rumination: US Supreme Court Decides Red River Water Rights Case

The Supreme Court’s recently issued Tarrant v. Hermann decision presents an interesting case study of river withdrawal rights, a body of law that will probably be getting more attention both domestically and internationally as hydrology patterns and population demands fluctuate in the future. I will not discuss the facts of the case as these are [...]

Shipping contributes to ocean acidification

The potential effect on surface water pH of emissions of SOX and NOX from global ship routes is assessed. The results indicate that regional pH reductions of the same order of magnitude as the CO2-driven acidification can occur in heavily trafficked waters. These findings have important consequences for ocean chemistry, since the sulfuric and nitric [...]

A coupled physical and economic model of the response of coastal real estate to climate risk

Barring an unprecedented large-scale effort to raise island elevation, barrier-island communities common along the US East Coast are likely to eventually face inundation of the existing built environment1 on a timescale that depends on uncertain climatic forcing. Between the present and when a combination of sea-level rise and erosion renders these areas uninhabitable, communities must [...]

Millennial-scale isotope records from a wide-ranging predator show evidence of recent human impact to oceanic food webs

Human exploitation of marine ecosystems is more recent in oceanic than near shore regions, yet our understanding of human impacts on oceanic food webs is comparatively poor. Few records of species that live beyond the continental shelves date back more than 60 y, and the sheer size of oceanic regions makes their food webs difficult [...]

Mobile demersal megafauna at artificial structures in the German Bight – Likely effects of offshore wind farm development

Within the next few decades, large underwater structures of thousands of wind turbines in the northern European shelf seas will substantially increase the amount of habitat available for mobile demersal megafauna. As a first indication of the possible effects of this large scale habitat creation on faunal stocks settling on hard substrata, we compared selected [...]

Uptake of human pharmaceuticals in bull sharks (Carcharhinus leucas) inhabiting a wastewater-impacted river

The presence of human pharmaceuticals in sewage-impacted ecosystems is a growing concern that poses health risks to aquatic wildlife. Despite this, few studies have investigated the uptake of active pharmaceutical ingredients (APIs) in aquatic organisms. In this study, the uptake of 9 APIs from human drugs was examined and compared in neonate bull sharks (Carcharhinus [...]

Biopolymer-reinforced synthetic granular nanocomposites for affordable point-of-use water purification

Creation of affordable materials for constant release of silver ions in water is one of the most promising ways to provide microbially safe drinking water for all. Combining the capacity of diverse nanocomposites to scavenge toxic species such as arsenic, lead, and other contaminants along with the above capability can result in affordable, all-inclusive drinking [...]

Effect of musical stimuli and white noise on rainbow trout (Oncorhynchus mykiss) growth and physiology in recirculating water conditions

Two musical stimuli transmissions (Mozart and Romanza) as compared with white noise treatment or control, both resulted in significantly higher growth performance in juvenile (6.7 ± 0.12 g) rainbow trout (Oncorhynchus mykiss) reared for 14 weeks. Carcass chemical composition and fatty acid composition (% of total fatty acids and mg/g carcass wet weight) did not [...]

Whole-lake nitrate addition for control of methylmercury in mercury-contaminated Onondaga Lake, NY

Methylmercury (MeHg) strongly bioaccumulates in aquatic food webs resulting in exposure to humans and wildlife through consumption of fish. Production of MeHg is promoted by anaerobic conditions and the supply of inorganic Hg (Hg2+), sulfate (SO42−), and labile organic carbon. The anaerobic sediments of stratified lakes are particularly active zones for methylation of Hg2+ and [...]

Algae: Times and Needs Have Changed For DOE Financing

We believe that there should be someone at the DoE who is willing to be honest – to tell our elected officials that times have changed, and so have the needs. They are not willing to tell you, but I am. If the US does not do something quickly we will soon be buying our [...]
