Unexpected Diversity Found Within Benthic Microbial Mats at Hydrothermal Springs in Crater Lake, Oregon [PDF]
Frontiers 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.

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

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

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

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

Geochemical monitoring of volcanic lakes. A generalized box model for active crater lakes
Annals of Geophysics, 2011 <p>In the past, variations in the chemical contents (SO42−, Cl−, cations) of crater lake water have not systematically demonstrated any relationships with eruptive activity.
