From 3D inverse modeling and available geologic data, three aeromagnetic data sets observed at Panga de Abajo, NE Baja California, México, suggest geomagnetic events of normal and reverse polarity in volcanic intrusive bodies of mafic composition intruding the sedimentary column…

Six gastropod species including two new ones, belonging to the family Architectonicidae, of the genera Architectonica, Granosolarium and Pseudomalaxis, are described for the Late Paleocene Sepultura Formation in Baja California, northwestern Mexico. The new species Architectonica bieleri and Architectonica bajaensis…

The relationship between the Southern Oscillation (SO) and the Pacific Decadal Oscillation (PDO) is studied by means of forced and secondary forecast models of the PDO. These models are constructed with the same indices frequently associated to different aspects of…

Nodosaurid ankylosaur remains from the Upper Cretaceous of Mexico are summarized. The specimens are from the El Gallo Formation of Baja California, the Pen and Aguja Formations of northwestern Coahuila, and the Cerro del Pueblo Formation of southeast Coahuila, Mexico.…

Irrigated agriculture is the largest water user in many regions, and agricultural water use efficiency and consumption has been studied by several authors. This paper provides a framework and application of economic valuation of water for agriculture in three regions…

The barnacle, Chelonibia testudinaria, is an obligate commensal of sea turtles that may show population variability according to the physical characteristics of the environment and properties of turtle hosts; therefore, we characterized the distributional patterns and the potential effects on…

Magnetotelluric (MT) observations collected at 17 sites along a 45-km profile were used to investigate the electrical conductivity structure in the Ojos Negros seismic zone, in northern Baja California, Mexico. In this region, seismic activity registered by a local network…

We describe a possible seismomagnetic precursor to the Mw 7.2 earthquake of April 4, 2010, with epicenter nearby the sierras El Mayor and Cucapah in NE Baja California, México, (El Mayor-Cucapah earthquake). We used total-field magnetic intensity data recorded on…
