Seabed digital elevation models and some possibilities of their morphometric analysis [PDF]

Vestnik MGTU, 2015
Seabed bathymetry is an important component of marine geology and geomorphology activity, so as cartography and paleogeography, geoecology and hydroacoustics and other applied areas of research also.

A two-part Seabed Geomorphology classification scheme (v.2); Part 1: Morphology Features Glossary

, 2020
This report updates the ‘Two-part Seabed Geomorphology classification scheme’ of Dove et al. (2016) and presents a new glossary (Part 1) of Seabed Morphology features. This Morphology glossary is intended to provide marine scientists with a robust and consistent way to characterise the seabed.

The seabed geomorphology and geological structure of the Firth of Lorn, western Scotland, UK, as revealed by multibeam echo-sounder survey [PDF]

Earth and Environmental Science Transactions of the Royal Society of Edinburgh, 2014
ABSTRACTThis paper presents recently collected swath bathymetry from the Firth of Lorn. 553 km2 of data were collected during 2012–2013 as part of the INIS Hydro (Ireland, Northern Ireland and Scotland Hydrographic Survey) programme.The area proves to consist of bedrock-dominated seabed, divided into narrow, stratigraphically-constrained and glacially ...

Submerged Carbonate Banks Aggregate Pelagic Megafauna in Offshore Tropical Australia

Frontiers in Marine Science, 2020
The conservation of marine biodiversity is firmly embedded in national and international policy frameworks. However, the difficulties associated with conducting broad-scale surveys of oceanic environments restrict the evidence base available for applied ...

Delivering seabed geodiversity information through multidisciplinary mapping initiatives: experiences from Norway

GEUS Bulletin, 2022
Geology is a core component of two major multidisciplinary seabed-mapping initiatives in Norway (MAREANO, Marine Base Maps for the Coastal Zone). Helped by Norway’s Nature Diversity Act, which acknowledges geological and landscape diversity alongside ...

300 Years of Degradation in Wales Estuaries and Coasts

Natural Resources Forum, EarlyView.
ABSTRACT The world's oceans are in a severe state of degradation, yet our understanding of that degradation is often based on changes observed only in the past 20–50 years. This narrow view leads to marine conservation efforts that aim to preserve already degraded ecosystems, shaped by shifted ecological baselines.

Storm tide amplification and habitat changes due to urbanization of a lagoonal estuary [PDF]

Natural Hazards and Earth System Sciences, 2020
In recent centuries, human activities have greatly modified the geomorphology of coastal regions. However, studies of historical and possible future changes in coastal flood extremes typically ignore the influence of geomorphic change.

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 ...
