Unexpected diversity found within benthic microbial mats at hydrothermal springs in Crater Lake, Oregon [PDF]

open access: yesFrontiers in Microbiology, 2022
Crater Lake, Oregon is an oligotrophic freshwater caldera lake fed by thermally and chemically enriched hydrothermal springs. These vents distinguish Crater Lake from other freshwater systems and provide a unique ecosystem for study.

Crater Lake Apoyo revisited--population genetics of an emerging species flock. [PDF]

open access: yesPLoS ONE, 2013
The polytypic Nicaraguan Midas cichlids (Amphilophus cf. citrinellus) have been established as a model system for studying the mechanisms of speciation and patterns of diversification in allopatry and sympatry. The species assemblage in Crater Lake Apoyo

Water quality of Wenchi Crater Lake in Ethiopia [PDF]

open access: greenMaejo International Journal of Science and Technology, 2008
Determination of physico-chemical properties of water samples from Wenchi Crater Lake in Ethiopia was carried out. Selected heavy metals in water, sediment, and plant samples from the lake were also comparatively determined.

A new lake in the Korbut Crater of Ebeko Volcano (Paramushir Island, Kuriles Islands)

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2022
The paper reports the appearance of a new crater lake on the Ebeko volcano. There has been no thermal lake within the Northern Crater since mid-2006. The last eruption began on October 19, 2016 and ended on November 19, 2021.

Insights into the recurrent energetic eruptions that drive Awu, among the deadliest volcanoes on Earth [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2020
The little-known Awu volcano (Sangihe Islands, Indonesia) is among the deadliest, with a cumulative death toll of 11 048. In less than 4 centuries, 18 eruptions were recorded, including two VEI 4 and three VEI 3 eruptions with worldwide impacts ...

Selected Crater and Small Caldera Lakes in Alaska: Characteristics and Hazards

open access: yesFrontiers in Earth Science, 2022
This study addresses the characteristics, potential hazards, and both eruptive and non-eruptive role of water at selected volcanic crater lakes in Alaska. Crater lakes are an important feature of some stratovolcanoes in Alaska.

Patterns in benthic biodiversity link lake trophic status to structure and potential function of three large, deep lakes. [PDF]

open access: yesPLoS ONE, 2015
Relative to their scarcity, large, deep lakes support a large proportion of the world's freshwater species. This biodiversity is threatened by human development and is in need of conservation.

Fluid-mineral dynamics at the Rincón de la Vieja volcano—hydrothermal system (Costa Rica) inferred by the study of major, minor and rare earth elements in the hyperacid crater lake

open access: yesFrontiers in Earth Science, 2023
Volcanic lakes are complex natural systems and their chemical composition is related to a myriad of processes. The chemical composition of major, minor, Rare Earth Elements (REE) and physico-chemical parameters at the hyperacid crater lake of Rincón de ...
