Ocean ambient noise on the Chukchi Plateau and its environmental correlates

Marine Environmental Research, 2023
Conducting research on ocean ambient noise under different sea ice conditions is highly important for the comprehension of the rapidly changing Arctic. We present the first results of ambient noise and its relationship to environmental forcing during the open-water, ice transition and ice-covered periods on the Chukchi Plateau. The ambient noise level (

Oceanic repeaters boost the global climatic impact of the Tibetan Plateau

Science Bulletin, 2023
The topography of the Tibetan Plateau (TP) has shaped the paleoclimatic evolution of the Asian monsoon. However, the influence of the TP on the global climate, beyond the domain of the Asian monsoon, remains unclear. Here we show that the Pacific and Atlantic Oceans act as efficient repeaters that boost the global climatic impact of the TP.

Magnetic anomaly map of Ori Massif and its implications for oceanic plateau formation

Earth and Planetary Science Letters, 2018
Many oceanic plateaus have been emplaced at or adjacent to mid-ocean ridges. To explain plateau volume and thickened crust compared to normal oceanic crust, hotspot–ridge interaction is commonly assumed, but the manner of interaction remains unclear. The

Anomalous crustal structures in ocean basins: Continental fragments and oceanic plateaus

Earth and Planetary Science Letters, 1980
Plateau-like features in ocean basins exhibit crustal structures which differ markedly from the relatively simple, three-layer model which applies to most of the oceanic crust. While some plateaus are known or thought to be fragments of continental crust (e.g. Rockall Bank, Lord Howe Rise), others appear to be of oceanic origin (e.g.

Biogenic aerosol in central East Antarctic Plateau as a proxy for the ocean-atmosphere interaction in the Southern Ocean

Science of The Total Environment, 2022
Ten years of data of biogenic aerosol (methane sulfonic acid, MSA, and non-sea salt sulfate, nssSO42-) collected at Concordia Station in the East Antarctic plateau (75° 06' S, 123° 20' E) are interpreted as a function of the Southern Annular Mode (SAM), Chlorophyll-a concentration (Chl-a; a proxy for phytoplankton biomass), sea ice extent and area.

The role of oceanic plateau subduction in the Laramide orogeny

Nature Geoscience, 2010
The cause of the Laramide phase of mountain building remains uncertain. Conceptual models implicate the subduction of either ocean ridges or conjugates of the buoyant Hess or Shatsky oceanic plateaux. Independent verification of these models has remained elusive, because the putative ridges or plateaux are no longer at the Earth’s surface.

Influence of geometry and eclogitization on oceanic plateau subduction

Earth and Planetary Science Letters, 2013
Abstract Subduction is driven by the negative buoyancy of the slab, which depends on both the temperature and composition of the lithospheric plate. In the case of subduction of an oceanic plateau, larger thickness of the lower-density crust and harzburgite layers can locally decrease the negative buoyancy available to drive subduction.

Oceanic plateaus as meteorite impact signatures

Nature, 1982
The oceanic plateaus are an enigmatic set of deep ocean structures1–5. Could these be signatures of ancient meteorite impacts? While numerous confirmed and suspected impact sites, ranging in age from Precambrian to Recent, have been identified on the continents6, none has thus far been identified in the oceans.

Oceanic plateaus, the fragmentation of continents, and mountain building

Journal of Geophysical Research: Solid Earth, 1982
Many anomalous rises in today's oceans may be submerged continental fragments detached from previous continents, ancient island arcs, or basaltic piles formed by hot spots and spreading centers. These rises are embedded in their respective moving oceanic plates and are fated to be consumed at active margins.

Is the Ordos Basin floored by a trapped oceanic plateau?

Earth and Planetary Science Letters, 2015
Abstract The Ordos Basin in China has about 10 km of Neoarchean to Quaternary sediments covering an enigmatic basement of uncertain origin. The basement is tectonically stable, has a thick mantle root, low heat flow, few earthquakes, and has been slowly subsiding for billions of years.
