Ancient and Modern Geochemical Signatures in the 13,500-Year Sedimentary Record of Lake Cadagno

open access: yesFrontiers in Earth Science, 2022
Although lake sediments are globally important organic carbon sinks and therefore important habitats for deep microbial life, the deep lacustrine biosphere has thus far been little studied compared to its marine counterpart.

Impacts on the deep-sea ecosystem by a severe coastal storm [PDF]

open access: yes, 2012
Major coastal storms, associated with strong winds, high waves and intensified currents, and occasionally with heavy rains and flash floods, are mostly known because of the serious damage they can cause along the shoreline and the threats they pose to ...

Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 247-262., 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.

Genomes of three bacteriophages from the deep subsurface aquifer

open access: yesData in Brief, 2019
Viral particles have been detected in the underground biosphere where they could be one of the main factors impacting microbial diversity, biogeochemistry and evolution.

Accessing the energy-limited and sparsely populated deep biosphere: achievements and ongoing challenges of available technologies

open access: yesProgress in Earth and Planetary Science, 2023
Microbes in marine sediments detected and counted by direct observation of membrane-filtered sediment samples stained with acridine orange. This technique can still be applied to high-biomass (> 105 cells/cm3) sedimentary habitats, such as organic-rich ...

Deglacial carbon cycle changes observed in a compilation of 127 benthic δ13C time series (20–6 ka) [PDF]

open access: yesClimate of the Past, 2018
We present a compilation of 127 time series δ13C records from Cibicides wuellerstorfi spanning the last deglaciation (20–6 ka) which is well-suited for reconstructing large-scale carbon cycle changes, especially for comparison with isotope ...

Cultural Values of Landscapes in the Practical Work of Biosphere Reserves

open access: yesLand, 2023
The purpose of this paper is to investigate the role of the landscape’s cultural values in the practical work of biosphere reserves and to identify what opportunities there are to increase awareness and knowledge about these values.

Contrasting responses to nutrient enrichment of prokaryotic communities collected from deep sea sites in the Southern Ocean [PDF]

open access: yes, 2013
Deep water samples (ca. 4,200 m) were taken from two hydrologically-similar sites around the Crozet islands with highly contrasting surface water productivities. Site M5 was characteristic of high productivity waters (high chlorophyll) whilst site M6 was

Rock surface attaching deep biosphere microbes and their functionality

open access: yes, 2023
Finnish deep bedrock and groundwaters create a niche that hosts diverse microbial life. Life in the deep is considered extreme as microbes face elevated pressure, absolute darkness, high salinity as well as low nutrient and carbon concentrations.

New perspectives in benthic deep-sea microbial ecology

open access: yesFrontiers in Marine Science, 2015
Deep-sea ecosystems represent the largest and most remote biome of the biosphere. They play a fundamental role in global biogeochemical cycles and their functions allow existence of life on our planet. In the last 20 years enormous progress has been made
