Lacustrine sedimentation by powerful storm waves in Gale crater and its implications for a warming episode on Mars

open access: yesScientific Reports, 2023
This investigation documents that the Rugged Terrain Unit, the Stimson formation, and the Greenheugh sandstone were deposited in a 1200 m-deep lake that formed after the emergence of Mt. Sharp in Gale crater, Mars, nearly 4 billion years ago.

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.

Salt shell fallout during the ash eruption at the Nakadake crater, Aso volcano, Japan: evidence of an underground hydrothermal system surrounding the erupting vent

open access: yesEarth, Planets and Space, 2018
A hot and acid crater lake is located in the Nakadake crater, Aso volcano, Japan. The volume of water in the lake decreases with increasing activity, drying out prior to the magmatic eruptions. Salt-rich materials of various shapes were observed, falling

Geochemical monitoring of volcanic lakes. A generalized box model for active crater lakes

open access: yesAnnals of Geophysics, 2011
<p>In the past, variations in the chemical contents (SO42&minus;, Cl&minus;, cations) of crater lake water have not systematically demonstrated any relationships with eruptive activity.

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

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.

CRATER LAKE COLONIZATION BY NEOTROPICAL CICHLID FISHES [PDF]

open access: yesEvolution, 2012
Volcanic crater lakes are isolated habitats that are particularly well suited to investigating ecological and evolutionary divergence and modes of speciation. However, the mode, frequency, and timing of colonization of crater lakes have been difficult to determine.
