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 ...

Deciphering key processes controlling rainfall isotopic variability during extreme tropical cyclones

Sanchez-Murillo, Ricardo; Durán-Quesada, Ana María ; Esquivel-Hernández, Germain; Rojas-Cantillano, Daniela; Birkel, Christian; Welsh Unwala, Kristen; Sánchez-Llull, Minerva; Alonso Hernández, Carlos M.; Tetzlaff, Doerthe; Soulsby, Chris; Boll, Jan; Kurita, Naoyuki; Cobb, Kim (2019-09)

The Mesoamerican and Caribbean (MAC) region is characterized by tropical cyclones (TCs), strong El Niño-Southern Oscillation events, and climate variability that bring unique hazards to socio-ecological systems. Here we ...

Tracking the water fingerprints of Cocos Island: A stable isotope analysis of precipitation, surface water, and groundwater

Corrales, José L; Sánchez Murillo, Ricardo; Esquivel-Hernandez, Germain; Herrera Herrera, Esteban; Boll, Jan (Revista de Biología Tropical, 2016)

The use of stable isotopes of water, both δ2H and δ18O has provided novel insights in hydrological studies, ecological applications, understanding climate variability, and reconstructing paleoclimate. However, information ...

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 ...
