“…7). Similar to aerial remnant volcanic activity in La Palma that generates high CO2 atmospheric concentration (Padrón et al, 2015), submarine remnant volcanic activity causes the acidification process found here. This activity is comparable with other CO2 vent systems worldwide (references within González-Delgado and .…”

“…These islands are located to the west of the archipelago and it is where the last historical eruptions have taken place. The last two were the Teneguía volcano in La Palma in 1971, and the Tagoro volcano in El Hierro in 2011 (Padrón et al, 2015;Santana-Casiano et al, 2016).…”

“…Currently, in the historic volcanic area in the south of La Palma (Cumbre Vieja volcano complex), there is a continuous degassing of CO2 (Carracedo et al, 2001;Padrón et al, 2015). Correspondingly, on the nearby shore, CO2 emissions have 55 been detected recently in two different locations: Las Cabras site (Hernandez et al, 2016) and Punta de Fuencaliente which has already been used for OA ecological studies (Pérez, 2017;Viotti et al, 2019).…”

Abstract. We present a new natural carbon dioxide (CO2) system located off the southern coast of La Palma Island (Canary Islands, Spain). Like others CO2 seeps, these seeps can be used as an analogue to study the effects of ocean acidification (OA) on the marine realm. With this aim, we present an accurate chemical characterization of the seeps system carbon emissions, describing the carbon system dynamics, by measuring pH, AT and CT, as well as, Ω aragonite and calcite. Our explorations on the area have found several emission points with similar chemical features. Here, the CO2 emission flux varies between 2.8 kg CO2 d−1 to 28 kg CO2 d−1, becoming a significant source of carbon. CO2 seeps are of volcanic origin and the alteration of local ocean chemistry is due to acid brackish water discharges. Although this kind of acidified system is not a perfect image of future oceans, this area of La Palma island is an exceptional spot to perform studies aimed to understand the effect of different levels of OA on the functioning of marine ecosystems. These studies can then be used to comprehend how life has persisted through past Eras, with higher atmospheric CO2, or to predict the consequences of present fossil fuel usage on the marine ecosystem of the future oceans.

“…Results from the statistical-graphical analysis of soil CO 2 efflux data showed two overlapping log-normal geochemical populations (background (B) and peak (P)) for São Vicente, Brava, and Fogo islands (Figure 3). The estimated mean values of the background population were 0.5, 2.2, and 1.0 g m −2 d −1 for São Vicente, Brava, and Fogo, respectively, similar to the background values reported for others oceanic volcanic islands with similar soil, vegetation, and climate conditions, e.g., as the Canaries (Cumbre Vieja volcano: 1.8 g m −2 d −1 , Padrón et al 2015; El Hierro Island: 1.4 g m −2 d −1 , Melián et al 2014;and Timanfaya volcano: 0.4 Hernández et al 2012a). On the other hand, mean values estimated for the peak populations were 7.6, 709, and 1,704 g m −2 d −1 for São Vicente, Brava, and Fogo, respectively.…”

Diffuse CO 2 emission surveys were carried out at São Vicente, Brava, and Fogo islands, Cape Verde, archipelago to investigate the relationship between diffuse CO 2 degassing and volcanic activity. Total amounts of diffuse CO 2 discharged through the surface environment of the islands of São Vicente, Brava, and Fogo were estimated in 226, 50, and 828 t d −1 , respectively. The highest CO 2 efflux values of the three volcanic islands systems were observed at the summit crater of Pico do Fogo (up to 15.7 kg m −2 d −1). Statistical graphical analysis of the data suggests two geochemical populations for the diffuse CO 2 emission surveys. The geometric mean of the peak population, expressed as a multiple of the geometric mean of the background population, seems to be the best diffuse CO 2 emission geochemical parameter to correlate with the volcanic activity (age of the volcanism) for these three island volcanic systems at Cape Verde. This observation is also supported by helium isotopic signature observed in the Cape Verde's fluids, fumaroles, and ground waters. This study provides useful information about the relationship between diffuse CO 2 degassing and volcanic activity at Cape Verde enhancing the use of diffuse CO 2 emission as a good geochemical tool, for volcanic monitoring at Cape Verde as well as other similar volcanic systems.

“…After that procedure, spatial distribution maps were constructed with sequential Gaussian simulation (sGs, Deutsch and Journel 1998;Cardellini et al 2003). This method was applied by interpolating over parts of the study area where the measurement sites were not set and to assess the uncertainty of total soil CO 2 emissions (Padrón et al 2008;Padrón et al 2015). First, the data were converted to normal scores using an open program (the code by Ashton Shortridge is freely available at https://www.msu.edu/~ashton/research/code/nscore.…”

Diffuse carbon dioxide emissions from hidden subsurface structures at Asama volcano, Japan

We measured diffuse carbon dioxide (CO 2 ) flux and soil temperature around the summit of Asama volcano, Japan to assess the diffuse degassing structure around the summit area. Soil CO 2 flux was measured using an accumulation chamber method, and the spatial distributions of CO 2 flux and soil temperature were derived from the mean of 100 sequential Gaussian simulations. Results show that soil CO 2 flux was high on the eastern flank of Kamayama cone and the eastern rim of Maekake crater, the outer cone. These areas mostly correspond to high-temperature anomalies. The average emission rate of diffuse CO 2 was calculated to be 12.6 t day −1 (12.2-14.6 t day −1 ). Such diffuse emissions account for 12 % of the total (diffuse and plume) CO 2 emissions from the summit area. The diffuse CO 2 anomalies probably reflect permeable zones controlled by local topography and hidden fractures bordering Maekake crater. The permeable zones are connected to the low-electrical-resistivity zone inferred to indicate both a hydrothermal fluid layer and an upper sealed layer made of clay minerals. Magmatic gas from the main conduit ascends to the volcano surface through this fluid layer and the permeable zones. These insights emphasize that the pathways and the connection between the pathways and the source of diffuse CO 2 combine to create the pattern of heterogeneous diffuse CO 2 emission seen at the surface. Only by using a combination of gas measurements and geophysical tools can we begin to understand the dynamics of this system as a whole.
