Microbial communities and mineral assemblages in sediments from various habitats at the Haima Cold Seep, South China Sea

Frontiers in Marine Science, 2023
Cold seeps create diverse habitats in the deep sea and play an important role in the global carbon cycling. Anaerobic oxidation of methane (AOM) and biogenic mineralization are essential carbon pathways of methane and carbon transformation in cold seeps,

Methane‐Driven Arsenic Biogeochemical Cycling in Deep‐Sea Cold Seeps: Implications for Oceanic Arsenic Geochemistry

Geophysical Research Letters
Arsenic accumulation in seafloor cold seeps is poorly understood. Here, we investigate the interplay between arsenic and methane biogeochemical cycles at the Haima cold seep, South China Sea.

Let's Make a Tubeworm! [PDF]

In this activity, centered on the ecology of a cold-seep community, students will investigate how deep-sea tube worms are adapted for a symbiotic relationship that allows them to survive.

Planktonic and sediment-associated aerobic methanotrophs in two seep systems along the North American margin [PDF]

, 2008
Methane vents are of significant geochemical and ecological importance. Notable progress has been made towards understanding anaerobic methane oxidation in marine sediments, however, the diversity and distribution of aerobic methanotrophs in the water ...

Germ Panic and Chalice Hygiene in the Church of England, c.1895–1930

Journal of Religious History, EarlyView.
The late‐Victorian medical revolution in bacteriology, and growing public awareness of hygienic standards and the danger of disease infection from germs, created alarm about the traditional Christian practice of drinking from a common cup at Holy Communion.

MICROORGANISMS OF MARINE COLD HYDROCARBON SEEPS

Microbiology&Biotechnology
Marine hydrocarbon seeps, due to their unique geophysical and geochemical characteristics, form unique conditions for the development of specific microbial communities. Diverse and interconnected metabolic activities of them underlie global ecological processes. In this review were considered the geophysical and chemical conditions for the formation of

Cold Seeps in a Warming Arctic: Insights for Benthic Ecology

Frontiers in Marine Science, 2020
Cold-seep benthic communities in the Arctic exist at the nexus of two extreme environments; one reflecting the harsh physical extremes of the Arctic environment and another reflecting the chemical extremes and strong environmental gradients associated ...

Studying Tech Diplomacy—Introduction to the Special Issue on Tech Diplomacy

Global Policy, EarlyView.
ABSTRACT This article serves as an introduction to the special issue on tech diplomacy, exploring its emergence and evolution as a distinct approach to global affairs in the era of the Fourth Industrial Revolution. Originating with Denmark's 2017 “TechPlomacy” initiative, tech diplomacy has gained global momentum, with over two dozen countries adopting

Sensing the sky's edge: Atmospheric insights into the Korean demilitarised zone

Area, EarlyView.
Short Abstract In this paper, I demonstrate that novel and creative ‘atmospheric methods’ not only provide us with a means of overcoming difficulties around access to border spaces, but also more importantly afford us new insights into how atmospherically attuned things and the materialities of weather become entangled with and produce border ...
