Dynamics and mass balance of El Chichón crater lake, Mexico [PDF]

open access: yesGeofísica Internacional, 2004
The mass balance of El Chichón crater lake is controlled by precipitations, evaporation and seepage through the lake bottom. The main non-meteoric source of water and Cl for the lake is a boiling spring (Soap Pool) discharging saline and neutral water ...

Environmental Effects of Volcanic Volatile Fluxes From Subaerial Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 103-116., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Drone monitoring of volcanic lakes in Costa Rica: a new approach

open access: yesDrone Systems and Applications, 2023
For the first time ever, samples were collected from volcanic lake waters in Costa Rica using an unmanned aerial vehicle (drone), which represents a major achievement in human–machine interaction and innovation in the technology sector. A Matrice 600 Pro

Sequence of infilling events in Gale crater, Mars: Results from morphology, stratigraphy, and mineralogy [PDF]

open access: yes, 2013
Gale Crater is filled by sedimentary deposits including a mound of layered deposits, Aeolis Mons. Using orbital data, we mapped the crater infillings and measured their geometry to determine their origin.

Hydrochemical and Hydroacoustic Investigation of the Yugama Acid Crater Lake, Kusatsu-Shirane, Japan

open access: yesFrontiers in Earth Science, 2021
The gases dissolved in the waters of volcanic lakes can present a serious hazard if the physical-chemical conditions change due to variations in the supply of magmatic gases.

Rare Earth Elements Variations in a Hyperacid Crater Lake and Their Relations With Changes in Phreatic Activity, Physico-Chemical Parameters, and Chemical Composition: The Case of Poás Volcano (Costa Rica)

open access: yesFrontiers in Earth Science, 2022
Decades of geochemical monitoring at active crater lakes worldwide have confirmed that variations in major elements and physico-chemical parameters are useful to detect changes in volcanic activity.
