Density vs distance for the DUNE beam from two recent geology density maps [PDF]

open access: yesPhys. Rev. D 95, 113004 (2017), 2016
The densities passed through for neutrinos going from Fermilab to Sanford lab are obtained using two recent density tables, crustal [1] and Shen-Ritzwoller[2], as well as the values from an older table PEMC[3].

Interim report on the ground-water resources of Manatee County, Florida [PDF]

open access: yes, 1955
A large part of western Manatee County is devoted to the growing of winter vegetables and citrus fruits. As in most of peninsular Florida, rainfall in the county during the growing season is not sufficient for crop production and large quantites of ...

An example of aquifer heterogeneity simulation to modeling well-head protection areas [PDF]

open access: yes, 2017
Groundwater management requires the definition of Well-Head Protection Areas (WHPA) for water supply wells. Italian law uses geometrical, chronological and hydrogeological criteria for WHPA identification, providing a groundwater travel time of 60 days ...

Application of an improved global-scale groundwater model for water table estimation across New Zealand [PDF]

open access: yesHydrology and Earth System Sciences, 2018
Many studies underline the importance of groundwater assessment at the larger, i.e. global, scale. The groundwater models used for these assessments are dedicated to the global scale and therefore not often applied for studies in smaller areas, e.g ...

Asymmetric continental deformation during South Atlantic rifting along southern Brazil and Namibia [PDF]

open access: yes, 2017
Plate restoration of South America and Africa to their pre-breakup position faces the problem of gaps and overlaps between the continents, an issue commonly solved with implementing intra-plate deformation zones within South America.

Evaluation of Groundwater Recharge Estimates in a Partially Metamorphosed Sedimentary Basin in a Tropical Environment: Application of Natural Tracers

open access: yesThe Scientific World Journal, 2014
This study tests the representativeness of groundwater recharge estimates through the chloride mass balance (CMB) method in a tropical environment. The representativeness of recharge estimates using this methodology is tested using evaporation estimates ...

Preliminary experimental results by the prototype of Sanya Incoherent Scatter Radar

open access: yesEarth and Planetary Physics, 2020
In the past decades, the Incoherent Scatter Radar (ISR) has been demonstrated to be one of the most powerful instruments for ionosphere monitoring. The Institute of Geology and Geophysics at the Chinese Academy of Sciences was founded to build a state-of-

Well design as a factor contributing to loss of water from the Floridan Aquifer, eastern Clay County, Florida [PDF]

open access: yes, 1962
A number of wells penetrating the Floridan aquifer in eastern Clay County were found to be losing water to permeable zones above this aquifer. A differential in artesian pressure was observed in closely spaced wells of similar depth.
