Comparison of Field and Virtual Vegetation Surveys Conducted Using Uncrewed Aircraft System (UAS) Imagery at Two Coastal Marsh Restoration Projects

open access: yesRemote Sensing
Traditional field vegetation plot surveys are critical for monitoring ecosystem restoration performance and include visual observations to quantitatively measure plants (e.g., species composition and abundance).

The European harmonised bathymetry grid EMODnet Bathymetry

open access: yesHydrographische Nachrichten, 2020
The EMODnet Bathymetry portal provides open and free access to the bathymetry of the European seas. This article presents the current status of the EMODnet Bathymetry project, its impact on the marine stakeholders, with examples from the German community, and provides an outlook to future developments.

The influence of rivers on seabird foraging ecology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

From distant shores to an emerging island: the role of surface and subsurface transport in modeling seed dispersal

open access: yesEcography, EarlyView.
Long‐distance seed dispersal by ocean currents plays a critical role in structuring coastal plant communities. As direct observations of this phenomenon are infeasible, numerical modeling is a valuable tool. Here, we use Lagrangian particle tracking to examine the colonization of the newly forming island Norderoogsand (German Bight, Wadden Sea) by five

Spaceborne active-passive optical fusion bathymetry in coastal waters: the implications of ICESat-2 photons

open access: yesInternational Journal of Digital Earth
Up-to-date bathymetric data is essential for global coastal management and protection. Conventional surveying equipment is not only inefficient but also difficult to reach on remote island coasts.

Linking species distribution models with population abundance to support adaptive fisheries management

open access: yesEcography, EarlyView.
Understanding how environmental variability structures essential fish habitat (EFH) is central to managing keystone populations in dynamic marine ecosystems. Using nearly three decades of standardized survey data (1994–2021) from the Adriatic Sea, we present the first basin‐scale, process‐based framework linking estimated habitat suitability and ...

Improved Arctic Ocean Bathymetry Derived From DTU17 Gravity Model

open access: yesEarth 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 ...

OESbathy version 1.0: a method for reconstructing ocean bathymetry with generalized continental shelf-slope-rise structures [PDF]

open access: yesGeoscientific 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 ...
