Geothermal Convection and Double Diffusion Based on Profiling Floats in the Black Sea
(
- Geophysical Research Letters
, 2021-01-25)
Here, we revisit the existing concepts of the vertical structure of deep layers in the Black Sea using data from sensors deployed on profiling floats. The deep transition layer (DTL) between 700 and 1,700 m acts as an ...
Deposition History and Paleo-Current Activity on the Southeastern Lomonosov Ridge and its Eurasian Flank Based on Seismic Data
(
- Geochemistry, Geophysics, Geosystems
, 2020)
A regional seismic survey on the southeastern Lomonosov Ridge (LR) and adjacent basins provides constraints on the coupled evolution of ocean circulations, depositional regime, and tectonic processes. First, Mesozoic strata ...
A Relationship Between ITCZ Organization and Subtropical Humidity
(
- Geophysical Research Letters
, 2020)
Motivated by the results of idealized studies on the self-aggregation of convection, we investigate a potential relationship between the degree of organization of the Intertropical Convergence Zone (ITCZ) and humidity based ...
The Fingerprints of Flexure in Slab Seismicity
(
- Tectonics
, 2020)
Earthquake moment tensors in eastern Pacific (ePac) slabs typically show downdip tensional (DT) axes, whereas in the western Pacific (wPac), they typically show downdip compressional (DC) axes or have mixed orientations ...
The Boulder Population of Asteroid 4 Vesta: Size‐Frequency Distribution and Survival Time
(
- Earth and Space Science
, 2021-01-26)
Dawn's framing camera observed boulders on the surface of Vesta when the spacecraftwas in its lowest orbit (Low Altitude Mapping Orbit, LAMO). We identified, measured, and mapped boulders in LAMO images, which have a scale ...
The practice of responsible research and innovation in “climate engineering”
(
- Wiley Interdisciplinary Reviews: Climate Change
, 2020)
Sunlight reflection and carbon removal proposals for “climate engineering” (CE) confront governance challenges that many emerging technologies face: their futures are uncertain, and by the time one can discern their shape ...
Coupling of the Subpolar Gyre and the Overturning Circulation During Abrupt Glacial Climate Transitions
(
- Geophysical Research Letters
, 2020-11-05)
We present a mechanism for self‐sustained ocean circulation changes that cause abrupt temperature changes over Greenland in a multimillennial climate model simulation with glacial CO2 concentrations representative of Marine ...
Compaction-Driven Fluid Localization as an Explanation for Lower Crustal Electrical Conductors in an Intracontinental Setting
(
- Geophysical Research Letters
, 2020)
We present electrical resistivity models, derived from magnetotelluric data, of the crust beneath the Bulnay region, Mongolia. They reveal that the lower crust contains a pattern of discrete zones (width of ~25 km) of low ...
Tectono‐Magmatic, Sedimentary, and Hydrothermal History of Arsinoes and Pyrrhae Chaos, Mars
(
- Journal of Geophysical Research: Planets
, 2020-12-23)
Arsinoes and Pyrrhae Chaos are two adjacent chaotic terrains located east of Valles Marineris and west of Arabia Terra, on Mars. In this work, we produced a morpho‐stratigraphic map of the area, characterized by a volcanic ...
Increasing Resolution and Resolving Convection Improve the Simulation of Cloud-Radiative Effects Over the North Atlantic
(
- Journal of Geophysical Research: Atmospheres
, 2020)
Clouds interact with atmospheric radiation and substantially modify the Earth's energy budget. Cloud formation processes occur over a vast range of spatial and temporal scales, which make their thorough numerical representation ...
