We use the term vertical migration to describe the mechanism of mass transport that moves trace petroleum hydrocarbons from subsurface accumulations to the surface. Vertical migration is the heart of geochemical exploration for petroleum. Although ou

Since introduction into the Chesapeake Bay watershed in the 1970s, blue catfish (Ictalurus furcatus) populations have increased, impacting native species. One strategy suggested to limit their growing numbers is to expand the existing commercial fish

We show that goldfish (Carassius auratus) voluntarily ingest liquid canola oil at the surface of the water and can swallow significant quantities of oil. The ability of fish to separate floating oil from water has not been tested previously, and the

Manganese (Mn) is a hypoxic reactive metal commonly found in marine sediments. Under hypoxic conditions the metal becomes fully reduced to Mn2+ and is biologically available to the benthic community for uptake. Mn is also a potent neurotoxin and it m

Difficult-to-find petroleum resources and expensive drilling drive the need for improved exploration methods. Although improvement can be made by technically advancing individual methods, greater improvement comes from integrating existing independen

The characterization of a miniaturized helium discharge ionization detector (μHDID) for micro gas chromatography through a number of parameterized experimental measurements is presented. The response of the detector is directly related to the He dis

A new approach is described for utilizing atomic layer-deposited alumina as a gas–solid stationary phase medium for microfabricated gas chromatography columns. After atomic layer deposition (ALD) of aluminum oxide, a chloroalkylsilane is utilized t

We report on a small (20 × 10 mm) micromachined device for the detection of gases in micro-gas chromatography (GC). It incorporates a micro-discharge across a 20-μm gap, and a remote electrode in the micro cavity that generates an electrical signal

Semi-packed columns containing an array of micropillars embedded within an open rectangular column structure are a new class of micro gas chromatography (μGC) columns introduced to provide higher separation efficiency and higher sample capacity. Thr
