Large quantities of the chemical oil dispersant Corexit were applied in the Gulf of Mexico (Gulf) in response to the Deepwater Horizon oil spill. Large data gaps regarding the potential transport, persistence and impact of Corexit in the Gulf existed at the time of the emergency response. Analytical methods for...
A three-part study was conducted into the impact of physiological and ecological variables on the net isotopic fractionation of hydrogen, α[subscript K₃₇], expressed in C₃₇ alkenones. First, alkenone-producer production, abundance, and export were characterized in the summertime Gulf of California and Eastern Tropical North Pacific using compound-specific, labeled in situ...
Acoustic scattering layers of biological origin have been observed for nearly 70 years across the world’s oceans. The organisms that comprise these layers are known to be important features in most oceanic ecosystems, providing a vital trophic link between small phytoplankton grazers and larger species. There are many aspects of...
The mesoscale circulation in the Gulf of California is investigated using a numerical model (Princeton Ocean Model). Forced by satellite-derived winds, the circulation in the gulf shows a complex pattern dominated in the southern gulf by multiple eddies. Near the coast and in most of the north gulf, the circulation...
Using gravity, magnetic, bathymetric and seismic
refraction data, I have constructed a geophysical cross-section
of the central part of the northern Gulf of California. The
section exhibits a crustal thickness of 18 km and features an
anomalous block of high density lower basement (3.15 g/cm³)
which probably resulted from rifting...
Geophysical surveys in the Gulf of California provided
the data to construct contour maps of bathymetry, free-air
anomalies and total field magnetic anomalies for the area
north of 27° N. Major faults such as the Ballenas-
Salsipuedes, Tiburón, Guaymas, and the South Cerro Prieto
are clearly observable on these maps....
