Improved Arctic Ocean Bathymetry Derived From DTU17 Gravity Model
Earth and Space Science, 2019 The existing bathymetry map of the Arctic is a compilation of ship soundings and digitized contours. Due to the presence of all‐year sea ice, costly operations and political restrictions, dense and full coverage of the Arctic is not possible, leaving ...

Structure and Propagation of Mesoscale Cyclonic Eddies in the Brazil–Malvinas Confluence
International Journal of Climatology, EarlyView.Between 1993 and 2022, 1386 cyclonic eddies were identified in the Brazil–Malvinas Confluence, one of the most energetic regions of the South Atlantic. While most eddies dissipated locally, a smaller number of individuals, more energetic, and longer lived propagated predominantly south‐westward and north‐eastward, driven by topographic constraints and ...

OESbathy version 1.0: a method for reconstructing ocean bathymetry with generalized continental shelf-slope-rise structures [PDF]
Geoscientific Model Development, 2015 We present a method for reconstructing global ocean bathymetry that combines a standard plate cooling model for the oceanic lithosphere based on the age of the oceanic crust, global oceanic sediment thicknesses, plus generalized shelf-slope-rise ...

Bathymetric Data Requirements for Operational Coastal Erosion Forecasting Using XBeach
Journal of Marine Science and Engineering, 2021 There is an increasing interest in the broad-scale implementation of coastal erosion early warning systems (EWS) with the goal of enhancing community preparedness to extreme coastal storm wave events.

Bathymetry-constrained navigation of Argo floats under sea ice on the Antarctic Continental Shelf
, 2020 Antarctic continental shelf waters are poorly sampled, particularly beneath sea ice during winter. Profiling floats could help fill this gap, but floats are unable to surface to obtain a satellite position when ice is present.

Journal of Quaternary Science, EarlyView.ABSTRACT While the Antarctic region has experienced significant climatic changes over the Holocene, few high‐resolution records have examined their effects on the local biota. In order to understand past ecological shifts and forecast future changes, it is important to obtain high‐resolution palaeoecological records from this region.

The Influence of Camera Calibration on Nearshore Bathymetry Estimation from UAV Videos
Remote Sensing, 2021 Measuring the nearshore bathymetry is critical in coastal management and morphodynamic studies. The recent advent of Unmanned Aerial Vehicles (UAVs), in combination with coastal video monitoring techniques, allows for an alternative and low cost ...
