Assessing the Effect of Large Igneous Provinces on Global Oceanic Redox Conditions Using Non‐traditional Metal Isotopes (Molybdenum, Uranium, Thallium)

open access: yesGeophysical Monograph Series, Page 305-323., 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.

New species of Laetmonice (Aphroditidae, Annelida) from bathyal and abyssal depths around Australia

open access: yesRecords of the Australian Museum
Research voyages on board RV ‘Investigator’ between 2015 and 2022 sampled benthic communities of Australia’s Eastern and Southern continental margins from the slope down to abyssal depths (463–5000 m) as well as the seamounts off the Indian Ocean ...

Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Abyssal deposit feeders are secondary consumers of detritus and rely on nutrition derived from microbial communities in their guts

open access: yesScientific Reports, 2021
Trophic ecology of detrital-based food webs is still poorly understood. Abyssal plains depend entirely on detritus and are among the most understudied ecosystems, with deposit feeders dominating megafaunal communities.

Composition and Ecological Roles of the Core Microbiome along the Abyssal-Hadal Transition Zone Sediments of the Mariana Trench

open access: yesMicrobiology Spectrum, 2022
The unique geological features of hadal trenches are known to influence both the structure and ecological function of microbial communities. It is also well known that heterotrophs and chemoautotrophs dominate the hadal and abyssal pelagic zones ...

Biogeochemical, Isotopic and Bacterial Distributions Trace Oceanic Abyssal Circulation. [PDF]

open access: yesPLoS ONE, 2016
We explore the possibility of tracing routes of dense waters toward and within the ocean abyss by the use of an extended set of observed physical and biochemical parameters. To this purpose, we employ mercury, isotopic oxygen, biopolymeric carbon and its

All the bedrooms a stage: Reconceptualizing sex as “performance” to sex as “rehearsal”

open access: yesFeminist Anthropology, EarlyView.
Abstract In the United States, sex is often spoken about in terms of performance, and naturally invokes language of theatricality. Sexual performance has been used as an umbrella term to refer to sexual satisfaction, behavior, embodiment, and also pathology in terms of conditions such as erectile dysfunction.

Bottom mixed layer derivation and spatial variability over the central and eastern abyssal Pacific Ocean [PDF]

open access: yesOcean Science
The bottom mixed layer (BML) of the abyssal ocean regulates heat exchange between the deep interior and seafloor, driving water–mass transformation and influencing global circulation.

High mercury accumulation in deep-ocean hadal sediments

open access: yesScientific Reports, 2021
Ocean sediments are the largest sink for mercury (Hg) sequestration and hence an important part of the global Hg cycle1. Yet accepted global average Hg flux data for deep-ocean sediments (> 200 m depth) are not based on measurements on sediments but are ...

Recent advances in multifunctional soft robots: A materials–structures–systems co‐design perspective for synergistic integration

open access: yesFlexMat, EarlyView.
Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...
