Chirripó Hydrological Research Site: advancing stable isotope hydrology in the Central American Páramo
(2020-01-25)
The Chirripó Hydrological Research Site (CHRS) is located within the Chirripó National Park, Costa Rica (between 3,100-3,820 m asl) whereby ~100 km2 are covered by Páramo, a high‐elevation tropical grassland ecosystem. A ...
Stable isotopic characterizacion of nitrate wet deposition in the tropical urban atmosphere of Costa Rica
(Springer, 2021-07-13)
Increasing energy consumption and food production worldwide results in anthropogenic emissions of reactive nitrogen into the atmosphere. To date, however, little information is available on tropical urban environments where ...
Environmental isotope applications in Latin America and the Caribbean region
(Taylor & Francis, 2020-11)
This Special Issue illustrates the use of environmental isotopes in studying and assessing hydrogeological and ecohydrological issues in the Latin America and the Caribbean (LAC) region. The issue includes twenty selected ...
Tracing water sources and fluxes in a dynamic tropical environment from observations to modeling
(Frontiers in Earth Science, 2020-11-06)
Tropical regions cover approximately 36% of the Earth’s landmass. These regions are home to 40% of the world’s population, which is projected to increase to over 50% by 2030 under a remarkable climate variability scenario ...
Bayesian estimates of the mean recharge elevations of water sources in the Central America region using stable water
(Elsevier, 2020)
Study region: Central America. Study focus: Knowledge of the mean recharge elevation (MRE) of water resources is important where water resources are vulnerable. The purpose of this study was to develop and apply a Bayesian ...
Rainfall, groundwater, and surface water isotope data from extreme tropical cyclones (2016-2019) within the Caribbean Sea and Atlantic Ocean basins
(Elsevier, 2020-06)
Under a changing climate, projections estimate that over the next thirty years, extreme Tropical Cyclones (TCs) will increase in frequency, with two to three times more Category 4 and 5 hurricanes in the Atlantic basin ...
Headwaters drive streamflow and lowland tracer export in a large-scale humid tropical catchment
(John Wiley and Sons Ltd, 2020)
Headwaters are generally assumed to contribute the majority of water to downstream users, but
how much water, of what quality and where it is generated are rarely known in the humid tropics.
Here, using monthly monitoring ...
Key hydrological processes in the Del Azul Creek basin, sub-humid Pampean Plain
(Elsevier B.V., 2021-02)
Groundwater plays an important role in the economic development of the Chaco-Pampean Plain (Argentina), where industry, agriculture and cattle farming are the main economic activities. The 66% of the country's population ...
A preliminary isotope-based evapotranspiration partitioningapproach for tropical Costa Rica
(John Wiley and Sons Ltd, 2021-07)
Spatially and seasonally distributed information on transpiration (T) fluxes is limited in the tropics. Here, we applied a coupled isotope mass balance model to separate water fluxes of T and evapotranspiration (ET) from ...
Stable isotopes reveal groundwater to river connectivity in a mesoscale subtropical watershed
(Taylor and Francis Ltd., 2021)
The Corumbataí River basin (São Paulo, Brazil) has a critical situation regarding water availability due to the intensive use to support agriculture and urbanization, requiring scientific information to face water demand. ...
