    Isotope hydrology and baseflow geochemistry in natural and human-altered watersheds in the Inland Pacific Northwest, USA 

    Sanchez-Murillo, Ricardo; Brooks, Erin S.; Elliot, William; Boll, Jan (2015-02-18)
    This study presents a stable isotope hydrology and geochemical analysis in the inland Pacific Northwest (PNW) of the USA. Isotope ratios were used to estimate mean transit times (MTTs) in natural and human-altered watersheds ...

    Spatial and Temporal Variation of Stable Isotopes in Precipitation across Costa Rica: An Analysis of Historic GNIP Records 

    Sánchez Murillo, Ricardo; Esquivel Hernández, Germain; Welsh, Kristen; S. Brooks, Erin; Boll, Jan; Alfaro Solís, Rosa; Valdés González, Juan (2013-11-27)
    The location of Costa Rica on the Central American Isthmus creates unique microclimate systems that receive moisture inputs directly from the Caribbean Sea and the Pacific Ocean. In Costa Rica, stable isotope monitoring ...

    Groundwater recharge mechanisms inferred from isoscapes in a complex tropical mountainous region 

    Sanchez-Murillo, Ricardo; Birkel, Christian (AGU Publications, 2016-05-23)
    Stable isotope variations and groundwater recharge mechanisms remain poorly understood across the tropics, particularly in Central America. Here stable isotopes (δ18O and δ2H) in groundwater, surface water, and rainfall ...

    Key drivers controlling stable isotope variations in daily precipitation of Costa Rica: Caribbean Sea versus Eastern Pacific Ocean moisture 

    Sanchez-Murillo, Ricardo; Birkel, Christian; Welsh, K.; Esquivel-Hernández, Germain; Corrales Salazar, José Leonardo; Boll, J.; Brooks, E.; Roupsard, O.; Saénz - Rosales, O.; Katchan, I,; Arce - Mesén, R.; Soulsby, C.; Araguás Araguás, L. (Elsevier, 2016)
    Costa Rica is located on the Central American Isthmus, which receives moisture inputs directly from the Caribbean Sea and the Eastern Pacific Ocean. This location includes unique mountainous and lowland microclimates, but ...

    Tracer hydrology in a hydrometric data-limited and complex tropical mountainous region: the case of the Central American Isthmus 

    Sanchez-Murillo, Ricardo; Esquivel-Hernández, Germain; Castro Chacón, Laura; Durán-Quesada, Ana María ; Guerrero Henández, Manuel; Delgado, Valeria; Barberena, Javier; Montenegro Rayo, Kata; Alvarado, Yaneth; Benegas, Laura; Hernández - Antonio, Arturo; Matamoros Ortega, Marcela; Ortega, Lucía; Terzer-Wassmuth, Stefan (European Geosciences Union, 2019)
    Numerous socio-economic activities are dependent on the seasonal rainfall and groundwater recharge cycle across the Central American Isthmus. Demographic growth and unregulated land use changes resulted in extensive surface ...

    Groundwater and surface water connectivity within the recharge area of Guarani aquifer system during El Niño 2014–2016 

    Batista, Ludmila; Gastmans, Didier; Sanchez-Murillo, Ricardo; Saeta Farinha, Bárbara; Rodrigues dos Santos, Sarah María; Hung Kiang, Chang (Wiley & Sons, 2018)
    Recharge areas of the Guarani Aquifer System (GAS) are particularly sensitive and vulnerable to climate variability; therefore, the understanding of infiltration mechanisms for aquifer recharge and surface run‐off generation ...

    Insight into the stable isotopic composition of glacial lakes in a tropical alpine ecosystem: Chirripó, Costa Rica 

    Esquivel-Hernández, Germain; Sanchez-Murillo, Ricardo; Quesada-Román, Adolfo; Mosquera, Giovanny; Birkel, Christian; Ball, Jan (Wiley & Sons, 2018)
    Tropical high‐elevation lakes are considered sentinels of global climate change. This work characterizes the hydrological conditions of tropical alpine glacial lakes located in the highlands of Chirripó, Costa Rica, using ...

    Preface to Stable isotopes in hydrological studies in the tropics: ecohydrological perspectives in a changing climate 

    Sanchez-Murillo, Ricardo; Durán-Quesada, Ana María (Wiley & Sons, 2019)
    Tropical regions (comprised between the Tropics of Cancer and Capricorn, 23.5°N to 23.5°S) cover approximately 36% of the Earth's landmass. They are home to 40% of the world's population, which is projected to increase ...

    Moisture transport and seasonal variations in the stable isotopic composition of rainfall in Central American and Andean Páramo during El Niño conditions (2015–2016) 

    Esquivel-Hernández, Germain; Mosquera, Giovanny; Sanchez-Murillo, Ricardo; Quesada Román, Adolfo; Birkel, Christian; Crespo, Patricio; Célleri, Rolando; Windhorst, David; Breuer, Lutz; Boll, Jan (John Wiley and Sons Ltd, 2019)
    High‐elevation tropical grassland systems, called Páramo, provide essential ecosystem services such as water storage and supply for surrounding and lowland areas. Páramo systems are threatened by climate and land use ...
