The Momentum of ‘Developed’: Bodies of Water, Aging Bodies and Malta's Interventions at the UN

History, EarlyView.
Abstract Histories of major powers continue to shape how many scholars conceptualize internationalism. By focusing on Malta's interventions at the UN challenges, this article challenges such narrative. In particular, it examines Arvid Pardo's 1967 petition that the seabed be reconceived and protected as the ‘common heritage of mankind’ and Vincent ...

Enhancing seabed sediment classification with multibeam echo-sounding and self-training: a case study from the East Sea of South Korea

Frontiers in Earth Science
IntroductionAccurate classification of seabed sediments is essential for marine spatial planning, resource management, and scientific research. While direct sampling yields precise sediment information, it is costly and spatially limited.

A validated 3D point‐cloud analysis workflow for the creation of seagrass canopy height models

Methods in Ecology and Evolution, EarlyView.
Abstract Seagrasses support highly productive ecosystems in both temperate and tropical waters and provide essential ecosystem services. Despite their importance, the vertical structure of seagrasses (i.e. the canopy) remains poorly characterised at the microscale, even though it is a strong predictor of ecological processes that influence both ...

A method for estimating sound speed and the void fraction of bubbles from sub-bottom sonar images of gassy seabeds

, 2007
There is increasing interest in the effect of bubbles in gassy sediment. This is, first, because ofthe impact those bubbles have on the structural integrity and load-bearing capabilities of thesediment; second, because the presence of bubbles can be ...

Biogeochemical, sedimentological and dinoflagellate‐based reconstruction of the Holocene palaeoenvironment of the east Limfjord, Denmark

Boreas, EarlyView.
To assess how the eastern part of the Limfjord system has changed over the Holocene, relative to the wider Limfjord and western Baltic region, a sedimentary succession spanning c. 9600–150 cal. a BP was collected from Nibe Bredning, near Sebbersund, from a shallow coastal inlet along the eastern connection between the Limfjord and the Kattegat (north ...

Truncated drumlins and their implication for past sea level reconstructions

Boreas, EarlyView.
Coastal erosion of glacigenic sediments, particularly in the form of retreating drumlin bluffs, is a key process in paraglacial landscape evolution during periods of relative sea‐level (RSL) rise. As marine transgression reworks formerly subaerial glacial terrains, drumlins act as discrete sediment sources generating characteristic erosional and ...

Sediment Dispersion at the New Auckland Marine Disposal Ground, Northeast New Zealand [PDF]

, 2013
A controversial history of near shore dredged material disposal east of Auckland, New Zealand, starting in the mid-1980s, resulted in the use of a temporary deep water site that did not satisfy the requirements of the London Dumping Convention.

Evolution, Routing and Reservoir Characteristics of Submarine Channels in a Structurally Deforming Slope Setting: Deep‐Water Joint Development Zone of Nigeria and São Tomé and Príncipe

Journal of Petroleum Geology, EarlyView.
ABSTRACT Deep‐water slope channels and associated facies are a major part of clastic sediment dispersal system extending from the shelf‐edge to the abyssal plain. The toe‐thrust area of the deep‐water Niger Delta enables the analysis of these channels and their interaction with evolving fault‐controlled sea‐floor topography to be determined ...

Recent Sediment Analysis, Study Case: Sub Bottom Profiler Data Line 8 Geomarine Research Vessels

Journal of Wetlands Environmental Management, 2019
North Aru Island’s offshore had a long exploration history since 1973 until present. The characteristics of seabed can be studied through the shapes, acoustic reflection pattern, type of substrate or sediment, or by living organisms at the seafloor.

Geological and geotechnical constraints in the Irish Sea for offshore renewable energy

Journal of Maps, 2020
A 1:1,000,000 map of the Irish Sea, within the Irish Economic Exclusion Zone, is presented highlighting the spatial distribution of potential geological and geotechnical constraints to offshore wind energy development.
