Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

Boreas, EarlyView.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

Authoring Terrestrial Planets with Diffusion Models

Computer Graphics Forum, EarlyView.
Abstract To support the design and subsequent generation of terrestrial planets for use in the creative media, we propose a solution that employs a generative model trained on satellite data from planetary bodies with a defined solid surface, such as the Earth and Mars.

Topology‐based Visual Analysis of Hydrothermal Plumes

Computer Graphics Forum, EarlyView.
Abstract Hydrothermal plumes are turbulent structures of intense heat and mineral smoke that rise and disperse into the deep ocean. Existing models generally characterize these systems as a single axisymmetric plume originating from a point source. However, this assumption breaks down in weakly venting, spatially distributed systems, where low‐flux ...

Bathymetry prediction from gravity data using combined linear regression and neural networks for enhanced cross-regional transferability

Geo-spatial Information Science
Linear regression (LR) and neural network methods are widely used to infer seafloor topography from satellite altimetry-derived gravity fields. LR methods are effective in capturing large-scale topographic features but often fail to resolve fine-scale ...

IODP Expedition 361 Bathymetry

, 2020
Operational bathymetry data were measured using 3.5 kHz and/or 12 kHz echo sounders. Raw data are available in ODEC/CSV and SEGY formats, and depth-corrected bathymetry is presented in SEGY format.

Comparative species distribution model framework for marine conservation and its application to loggerhead turtles in the Mediterranean

Conservation Biology, EarlyView.
Abstract Modeling species distributions in dynamic pelagic environments remains challenging, particularly for wide‐ranging and highly mobile species when there is limited guidance on model performance. This limitation constrains the effective use of species distribution models (SDMs) in marine conservation, where robust and transferable predictions are

Band Weight-Optimized BiGRU Model for Large-Area Bathymetry Inversion Using Satellite Images

Journal of Marine Science and Engineering
Currently, using satellite images combined with deep learning models has become an efficient approach for bathymetry inversion. However, only limited bands are usually used for bathymetry inversion in most methods, and they rarely applied for large-area ...
