Improving seed‐based restoration in Eelgrass (Zostera marina) in combined aquarium and field experiments

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Seagrass restoration efforts are being implemented globally to accelerate the slow natural recolonization success. Among the various existing methods, seed‐based approaches offer the greatest scalability for species like Zostera marina, yet these methods remain undeveloped for a number of sub‐tidal systems like the Baltic Sea ...

Mantle Exhumation and Post‐Rift Magmatism at an Oblique Magma‐Poor Continental Margin

open access: yesGeophysical Research Letters
Continental breakup is a fundamental tectonic process, which leads to seafloor spreading and the generation of oceanic crust. However, the current understanding of continental margins, based largely on 2‐D seismic transects, is inadequate to capture the ...

Specialized Committees of International Organizations an Important Source of Organizational Autonomy

open access: yesRegulation &Governance, EarlyView.
ABSTRACT Assigning the preparation of decisions to specialized committees composed of member state representatives is a widespread response to the ‘governor's dilemma’, that is, the tension between competence and control, in international organizations (IOs). We theorize a causal mechanism referring to self‐selection and agenda‐setting effects and show

Is plate tectonis withstanding the test of time?

open access: yesAnnals of Geophysics, 1997
Since the theory of plate tectonics was first proposed thirty years ago, some problems have arisen in its practical application. These call into question its fundamental assumptions of horizontal plate motion, hotspot fixity, true polar wander ...

A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

open access: yesSedimentology, EarlyView.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

A Detailed Reconstruction of the Woodlark Basin

open access: yesGeochemistry, Geophysics, Geosystems
An animated 100,000‐year‐interval tectonic reconstruction of the Woodlark Basin in the southwest Pacific illustrates how, at intermediate initial spreading rates, orogenic continents break up (dyke model), spreading segments nucleate, transform faults ...

Formation process of the gravel‐dominated deposit from the 2011 Tohoku‐oki tsunami in Ofunato, northeastern Japan, inferred by integrating sedimentology and tsunami modelling

open access: yesSedimentology, EarlyView.
ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

Sedimentary biogeochemical provinces in the northern limit of the oxygen minimum zone from the northeastern Mexican Pacific

open access: yesSedimentology, EarlyView.
ABSTRACT Continental margins are reservoirs of materials of terrestrial and marine origin, and they play a crucial role in understanding the spatial and temporal variability of biogeochemical cycles. This, in turn, provides insights into the development and intensity of oxygen minimum zones (OMZs).

Climate conditions on the South‐Iberian Palaeomargin during the latest Pliensbachian to early Toarcian: A mineralogical and geochemical study from hemipelagic deposits

open access: yesSedimentology, EarlyView.
ABSTRACT The integrated analysis of lithofacies, mineralogy and geochemistry of the hemipelagic marine succession exposed in La Cerradura section (South‐Iberian Palaeomargin) provides new information to characterise the palaeoenvironmental conditions during the latest Pliensbachian to early Toarcian, including the Jenkyns Event.

The Seismic Expression of Core Complex‐Style Extensional Detachment Faults in Rifted Margins

open access: yesTerra Nova, EarlyView.
ABSTRACT The identification of core complex‐style extensional detachment faults (CCDFs) in rifted margins is crucial for accurately restoring their stratigraphic and thermal histories. Yet recognising CCDFs in seismic reflection images is challenging due to their faint topographic expression; the lack of associated abrupt offset in seismic reflections;
