Book Review: Echoes of Life: What Fossil Molecules Reveal about Earth History.

The year 1936 marks the beginning of organic geochemistry. It started with Alfred Treibs’ discovery of porphyrins in petroleum; compounds that closely resemble chlorophylls in plant matter. Another 25 years would pass before scientists recognized that these compounds, known as biomarkers, could reveal insights into the evolution of plants and animals spanning a time frame […]

The International Network of Environmental Forensics 2014 Conference

The International Network of Environmental Forensics (INEF) 2014 Conference will be held at St John’s College in Cambridge, UK from August 4-6.  Environmental forensics involves the use of a broad array of scientific techniques to not only identify a pollutant in the environment, but also apportion its introduction source and timing, often in support of finding a […]

This isn’t your average CSI, the International Network of Environmental Forensics (INEF)

Next week (June 10-12) at the Pennsylvania State University (PSU) the International Network of Environmental Forensics conference is being held.  This isn’t your typical crime scene investigation but, as defined by the INEF, “environmental forensics is the use of scientific techniques to identify the source, age, and timing of a contaminant into the environment.”  We […]

Petroleum Biomarkers and Tarballs at the 36th International Symposium on Capillary Chromatography and the 9th GCxGC Symposium

I’d like to invite my colleagues to a preliminary view of an upcoming presentation in Riva del Garda, Italy for the 36th International Symposium on Capillary Chromatography and the 9th GCxGC Symposium.  We’ve been working on characterizing tarballs that could have originated from the Deepwater Horizon oil spill in the Gulf of Mexico in 2010.  […]

Characterization of Gulf Region Tarballs

IXTOC I & Deepwater Horizon both are estimated to have dumped nearly 5 million barrels of oil into the gulf region. In 2011, a year after the Deepwater Horizon spill heavy oil and tar balls were washing up on the beaches of the gulf coast.  Tar near where the IXTOC I oil rig sank can […]

20th Norwegian symposium on Chromatography stays Unique in its kind

January 8-10  the 20th edition of the Norwegian Symposium on chromatography was organized in Sandefjord, Norway.  This symposium takes place every 2nd year and has developed into a successful event where around 240 chromatographers get together to present and learn developments on chromatography. The symposium offers a nice combination of scientific and commercial developments with […]

Gulf Oil Spill: Understanding SSRB, SBO, SOM and tarballs.

More Tarballs, GCxGC, and Hopane and Sterane Biomarkers

I was hoping someone would challenge me on my last post about fingerprinting oil spills through tarballs that might originate from the BP Deepwater Horizon event.  I showed a couple of tarball GCxGC-FID chromatograms on Rxi-5ms x Rxi-17Sil MS, which looked quite dissimilar.  But could they originate from the same oil spill?  It is possible, […]

Tarballs! GCxGC and Environmental Forensics…

I haven’t seen my colleague Chris English this excited in quite a while, since we got tarballs from the Florida panhandle to analyze by a variety of methods, including GCxGC-FID.  In fact, I thought he’d post a blog by now on this subject, but since he hasn’t, I’m stepping in! I analyzed multiple tarballs “extracted” […]

Is the BP Gulf Oil Well Still Spilling?

On August 18th while collecting ocean water surface samples near Long Beach Mississippi several large oil slicks were discovered. Some of the oil appeared to be partially dispersed and had a distinctive red-frothy texture.1 Other information from the Florida coast reported an increase in oil washing up on shore.2 On August 23rd the Press-Register 3 […]
