TL;DR: It is shown that DOSS was sequestered in deepwater hydrocarbon plumes at 1000-1200 m water depth and did not intermingle with surface dispersant applications, and underwent negligible, or slow, rates of biodegradation in the affected waters.

TL;DR: This work proposes an automated compound identification algorithm (CIA) for the analysis of ultra-high-resolution mass spectra of natural organic matter acquired by electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry and finds that CIA works well for data sets with high mass accuracy and can accurately determine the elemental formulas for >95% of all compounds.

TL;DR: To demonstrate the feasibility and utility of this method, uniformly 13C-labeled ribonucleotides were used to synthesize a 31 nucleotide HIV TAR RNA that was analyzed by 3D-NMR.

TL;DR: Bacterial transformation of this diatom-derived sulfonate represents a previously unidentified and likely sizeable link in both the marine carbon and sulfur cycles.

TL;DR: Detailed airborne, surface, and subsurface chemical measurements, primarily obtained in May and June 2010, are used to quantify initial hydrocarbon compositions along different transport pathways during the Deepwater Horizon oil spill, suggesting relatively little variation in leaking hydrocarbon composition over time.
