Subducted Carbon From Mantle Plume in Mid‐Ocean Ridge Basalts
Geophysical Research LettersDeciphering the Earth's deep carbon cycle, from mantle plumes to mid‐ocean ridges, remains incompletely understood. In this study, we analyze the magnesium isotope composition of basalts collected from the South Mid‐Atlantic Ridge (SMAR), which have been

DQN‐Guided Subset‐Induced OCSVM Kernel Approximation for Imbalanced Anomaly Detection
IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.Anomaly detection under limited normal data remains a fundamental challenge due to severe class imbalance and scarcity of anomalies. We propose a novel framework that reformulates support vector selection in One‐Class SVM as a sequential decision‐making problem.

On the Potential for Bioenergy and Biofuels from Hydrothermal Vent Microbes [PDF]
Oceanography, 2012 The discovery of deep-sea hydrothermal vents caused scientists to reconsider their notions about life in the deep sea. In these seemingly inhospitable environments, free-living microbes, as well as microbial-animal symbioses, thrive in the warm waters ...

The singing phenology of Bachman's sparrow: implications for monitoring programs
Wildlife Society Bulletin, EarlyView.We used automated recording units, weather data, and multiple logistic regression with generalized estimating equations to determine the annual singing period and influences on singing behavior of Bachman's sparrow in Texas, USA, surveying daily for 2 years.

Pulsated Global Hydrogen and Methane Flux at Mid‐Ocean Ridges Driven by Pangea Breakup
Geochemistry, Geophysics, Geosystems, 2020 Molecular hydrogen production occurs through the serpentinization of mantle peridotite exhumed at mid‐ocean ridges. Hydrogen is considered essential to sustain microbial life in the subsurface; however, estimates of hydrogen flux through geological time ...

Deep blueprint: A literature review and guide to automated image classification for ecologists
Journal of Animal Ecology, EarlyView.A practical, literature‐grounded review that gives ecologists a clear, modular workflow for deep learning image classification. With code, GUIs and a novel deep sea case study (automated deep sea biotope classification) it lowers technical barriers and provides a usable blueprint for accelerating, standardising, and scaling ecological image analysis ...

Partial Melting of Lower Oceanic Crust Gabbro: Constraints From Poikilitic Clinopyroxene Primocrysts
Frontiers in Earth Science, 2018 Successive magma batches underplate, ascend, stall and erupt along spreading ridges, building the oceanic crust. It is therefore important to understand the processes and conditions under which magma differentiates at mid ocean ridges.
