Isotopes in the Tropics

Stable Isotopes Research Group & Water Resources Management Laboratory at the National University of Costa Rica #SomosUNACR

This month, we had the pleasure of hosting Edgardo Barrientos from Universidad Autónoma of Honduras. He's doing an interesting work on the isotopic characterisation of precipitation in Honduras as part of his MSc in Water Resources. Stay tuned for the results! #somosUNACR #UNAH

A pending task is now completed! We have set up our 13C #Picarro analyzer with a TOC Aurora analyzer. This new capability will help us to continue exploring the #isotopic composition of DOC and DIC sources in our study sites.

Desde @IsotopesTropics and @comunidadUNACR aportamos a la discusión sobre la gestión del recurso hídrico en Costa Rica. Necesitamos cambios urgentes para el bien de tod@s.

Excellent paper! Congrats @EsquiveG

Glad to see published this review on Páramo water resources research led by Giovanny Mosquera. I am happy to have contributed on this much-needed paper

I could not make to #EGU23 in person but I will virtually be presenting a work on Costa Rican and Andean Paramo ecohydrology modeling. Check it out next Wednesday 26 during PICO session HS7.9 (16:30-18:00 CET).

Great to be part of this first RM where we’ll be discussing about water stable isotopes and convective rain events @iaeaorg @comunidadUNACR

[Germain Esquivel-Hernández @EsquiveG]

On my way to El Salvador to provide an IAEA national training course on radon measurements in surface water and groundwater in the field and lab. Looking forward to continuing our collaboration with @iaeaorg and my colleagues at @marn_salvador on isotope hydrology.

10 years already..!

[Germain Esquivel-Hernández @EsquiveG]

On March 20 2013 we collected our first precip sample at @comunidadUNACR. We are officially celebrating 10 yrs of continuous sampling (1178 samples and counting). Take a look at our 'lab' at that time! We were ready to break on through to the isotope side!

To celebrate #WorldWaterDay2023 we'd like to share part of our work: (1/6)

And many others... A great effort from multiple researchers and organisations/sponsors.

[Germain Esquivel-Hernández @EsquiveG]

Last Saturday I spent a nice day in the field with @andres_abarca and @EmanuelMV2612. We successfully collected surface and deep water samples for analysis of WSI, 222Rn and ionic species at Laguna Hule (volcanic lake).

Great contribution by Germaín Esquivel, congrats!

[Germain Esquivel-Hernández @EsquiveG]

I took my first steps as scientist in the atmospheric chemistry community. Thus I am very happy to share our new paper on nitrate isotopes (δ15N, δ18O) in precipitation https://t.co/F4dUcdvCoi
