Error estimation for gridded bathymetry [PDF]

2015 IEEE Applied Imagery Pattern Recognition Workshop (AIPR), 2015
Estimating the uncertainty or predicted accuracy of gridded products that are generated from historical bathymetric survey data is of high interest to the maritime navigation community. Surface interpolation methods used for gridding survey data in practice are well established. This paper investigates error estimation methods for gridded bathymetry in

Future directions in hydrography using satellite-derived bathymetry [PDF]

, 2013
Satellite remote sensing provides useful reconnaissance tool for mapping near-shore bathymetry, characterizing a coastal area and monitoring any seafloor changes that may have occurred since the last hydrographic survey of the area.

Marine silicon for biomedical sustainability

BMEMat, EarlyView.
Schematic illustrating marine silicon for biomedical engineering. Abstract Despite momentous divergence from oceanic origin, human beings and marine organisms exhibit elemental homology through silicon utilization. Notably, silicon serves as a critical constituent in multiple biomedical processes.

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

Remote 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

Hydrographische 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

Biological 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 ...

Using Multibeam Echosounders for Hydrographic Surveying in the Water Column: Estimating Wreck Least Depths [PDF]

, 2015
Wreck superstructure can extend into the water column and pose a danger to navigation if the least depth is not accurately portrayed to mariners. NOAA has several methods available to acquire a wreck least depth: lead line, wire drag, diver investigation,

Flow and retreat of the Late Quaternary Pine Island-Thwaites palaeo-ice stream, West Antarctica [PDF]

, 2010
Multibeam swath bathymetry and sub-bottom profiler data are used to establish constraints on the flow and retreat history of a major palaeo-ice stream that carried the combined discharge from the parts of the West Antarctic Ice Sheet now occupied by the ...

The effect of trait choice on hybrid species distribution model projections under climate change

Ecography, EarlyView.
Species distribution models (SDMs) have been increasingly combined with thermal performance data to enhance their transferability and to provide a physiological explanation for the predicted geographic patterns. Yet, while it is widely acknowledged that thermal sensitivities may vary among biological traits, it remains largely unexplored to what extent

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

International 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.
