“…The increase in CO 2 concentration in the accumulation chamber at a known volume adhering to the soil is directly proportional to the CO 2 flux [45][46][47]. This method, modified and applied by [48,49], is commonly utilized in the scientific community for geochemical monitoring in volcanic areas [7,9,12,18,19,22,24,25,[50][51][52][53][54][55][56][57][58][59][60].…”

The last increased volcanic activity of the Stromboli volcano, from 2016 to 2018, was characterized by increases in the number and frequency of crater explosions and by episodes of lava overflow. The volcanic activity was monitored utilizing CO2 soil fluxes acquired from the Stromboli summit area (STR02 station). To better understand the behavior of the shallow plumbing system of the Stromboli volcano in the period of 2016–2018, we utilized a large data set spanning from 2000 to 2018. The data in this last period confirm a long growing trend of CO2 summit degassing, already observed in the years since 2005 (reaching 23,000 g·m−2·d−1). Moreover, within this increasing trend, episodes of sudden and sharp increases in the degassing rate, up to 24.2 g·m−2·d−2 were recorded, which are correlated with the observed paroxysmal activity (increased summit explosions and overflow).

“…Here, we present a Bayesian mixing isotope model (R package Simmr; Parnell and Inger, 2016) to determine the influence of andesitic water (i.e., waters associated with more silicic andesitic magmatism typical of mature volcanic arc systems; Taran et al, 1989; in hydrothermal manifestations across Costa Rica. Hydrothermal samples (N 409) correspond to stable isotope archives and recent sampling efforts in Costa Rica (see Ramírez-Leiva et al, 2017 for sampling details).…”

“…Recharge is analyzed from isotopic lapse rates and main percolation elevations, as well as from precipitation to groundwater isotopic ratios (hereafter P/GW; Jasechko and Taylor, 2015). Third, the influence of magmatic-derived fluids in volcanic mountainous aquifers is reviewed from an andesitic water contribution perspective (i.e., waters associated with more silicic andesitic magmatism typical of mature volcanic arc systems; Taran et al, 1989; based on a Bayesian mixing model approach. Fourth, advances in tracer-aided spatiallydistributed models are discussed from a flow path, runoff generation, and water age standpoint (Birkel and Soulsby, 2015;Alo-Alo et al, 2017).…”

Tracing Water Sources and Fluxes in a Dynamic Tropical Environment: From Observations to Modeling

et al. 2020

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 often exacerbated by El Niño Southern Oscillation (ENSO) and other climate teleconnections. In the tropics, ecohydrological conditions are typically under the influence of complex land-oceanatmosphere interactions that produce a dynamic cycling of mass and energy reflected in a clear partition of water fluxes. Here, we present a review of 7 years of a concerted and continuous water stable isotope monitoring across Costa Rica, including key insights learned, main methodological advances and limitations (both in experimental designs and data analysis), potential data gaps, and future research opportunities with a humid tropical perspective. The uniqueness of the geographic location of Costa Rica within the mountainous Central America Isthmus, receiving moisture inputs from the Caribbean Sea (windward) and the Pacific Ocean (complex leeward topography), and experiencing strong ENSO events, poses a clear advantage for the use of isotopic variations to underpin key drivers in ecohydrological responses. In a sequential approach, isotopic variations are analyzed from moisture transport, rainfall generation, and groundwater/surface connectivity to Bayesian and rainfall-runoff modeling. The overarching goal of this review is to provide a robust humid tropical example with a progressive escalation from common water isotope observations to more complex modeling outputs and applications to enhance water resource management in the tropics.
