Magdalena Ridge Observatory Interferometer automated alignment system
Proceedings of SPIE, 2010Here is presented the current outline and progress of MROI's automated alignment system design. Depending on the location of each of MROI's unit telescopes (UT), light can travel distances ranging from 460 to 660 meters via several reflections that redirect the beam's path through the beam relay system (BRS), delay line system (DLS), beam ...

Magdalena Ridge Observatory Interferometer: the control system of the unit telescopes
Proceedings of SPIE, 2008This paper describes the telescope control system for the Magdalena Ridge Observatory Interferometer. To achieve the rapid development time required by the project we made use of two software packages, LabVIEW from National Instruments and TCSpk from Tpoint Software.

Estuarine, Coastal and Shelf Science, 2020
Abstracts Comparison of geo-referred bathymetric datasets from 2000 to 2017, at different timescales, allowed to analyze changes in the sedimentary balance and to determine patterns of morphological adjustment in the Magdalena River (South America). The Magdalena River has one of the highest sediment yields among the major rivers of the world.

Petroleum systems of the Upper Magdalena Valley, Colombia
Marine and Petroleum Geology, 2004Abstract In the Upper Magdalena Valley, Colombia, four petroleum systems were identified. Two petroleum systems are located in the Girardot sub-basin and the other two in the Neiva sub-basin. Limestones laterally changing to shales of the lower part of the Villeta Gp, deposited during Albian and Turonian marine flooding events, constitutes the main ...

Astronomical site monitoring system for the Magdalena Ridge Observatory
SPIE Proceedings, 2004The astronomical site parameters for the Magdalena Ridge Observatory (MRO) are being studied from numerous aspects including meteorological, environmental, seismic and sky quality (e.g. "seeing", cloud cover). Results to date indicate that MRO is an excellent site for astronomical observing. Seeing measurements of less that 1 arc second in the optical

Benefits of Coordinated Water Resource System Planning in the Cauca-Magdalena River Basin
Water Economics and Policy, 2018The Magdalena watershed in Colombia is the most densely populated and economically important region in the country. While Colombia is generally classified as a water-rich country, it is expected that water shortages will occur in the future without adequate planning and investments in water management infrastructures.

A New Species of Astyanacinus (Characiformes: Characidae) from the Río Magdalena System, Colombia
Copeia, 2012Astyanacinus yariguies, a new species, is described from Rio Cascajales, Rio Magdalena system, in the municipality of El Carmen, Santander, Colombia. This species is assigned to Astyanacinus because it exhibits all the diagnostic characters of the genus, including 25–36 branched anal-fin rays (28–30 in the new species), and a coloration pattern with ...

Journal of Morphology, 2016
ABSTRACTWe studied anatomical and functional aspects of the reproductive system of females of the Magdalena river stingray Potamotrygon magdalenae using microscopic and macroscopic analysis of each organ. Although the reproductive tract was fully functional on both side, the left organs possibly have a greater contribution to reproductive success ...
