Arctic Ocean Scientific Drilling: The Next Frontier [PDF]

open access: yesScientific Drilling, 2010
The modern Arctic Ocean appears to be changing faster than any other region on Earth. To understand the potential extent of high latitude climate change, it is necessary to sample the history stored in the sediments filling the basins and covering the ...

A Compact Hollow Fiber Electrode Assembly Architecture for Continuous Electrochemical Marine Carbon Dioxide Removal

open access: yesAdvanced Energy Materials, EarlyView.
A coaxial, membrane‐integrated hollow fiber electrode assembly (HFEA) is developed for continuous marine carbon mineralization. By utilizing a sub‐millimeter inter‐electrode gap, the HFEA minimizes Ohmic losses, achieving 50% energy reduction and over 85% DIC removal.

Assessing the preservation potential of successive hurricane overwash deposits in Florida, USA mangroves

open access: yesScientific Reports
Geologic records of tropical cyclones (TCs) in low-energy, back-barrier environments are established by identifying marine sediments via their allochthonous biogeochemical signal. These records have the potential to reconstruct TC intensity and frequency

Geological History of the Dry Valleys, Antarctica, Based on the Stable Isotope Studies

open access: yesAntarctic Record, 1977
In 1973, DVDP 4 drilling was performed to obtain unconsolidated sediments of Lake Vanda, McMurdo Oasis. The cored sediments were found to contain layered salt concretions composed of gypsum, thenardite and calcite.

BarnebyLives: An R package to create herbarium specimen labels and clean spreadsheets

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Accessioning herbarium specimens is labor intensive, yet remains vital for research in ecology, evolution, and conservation. As institutional support for herbaria declines, efficient tools are needed to streamline this process. The R package BarnebyLives was developed to assist collectors by supplementing collection notes, verifying ...

Methane Gas Hydrate Morphology and its Effect on the Stiffness and Damping of some Sediments [PDF]

open access: yes, 2009
Gas hydrates are ice–like compounds found in deep sea sediments and permafrosts. Concise detectionand quantification of natural methane gas hydrate deposits, will allow for a more robust assessmentof gas hydrate as a potential energy resource or natural ...
