Comparing convolutional neural network and random forest for benthic habitat mapping in Apollo Marine Park

Remote Sensing in Ecology and Conservation, EarlyView.
A comparison of Convolutional Neural Network (CNN) and Random Forest (RF) model predictions of benthic habitats within Apollo Marine Park. The CNN (left) and RF (right) classification maps show the spatial distribution of three habitat types: high energy circalittoral rock with seabed‐covering sponges, low complexity circalittoral rock with non‐crowded

The Port Norfolk Project: Improved Raster Navigation Products From High Resolution Source Data [PDF]

, 2011
With increasing capabilities in technology, modern hydrographic surveys are comprised of similarly increasing amounts of data, only a minute fraction of which is currently available in the nautical charts produced by the NOAA Office of Coast Survey (OCS).

Evaluating methods for high‐resolution, national‐scale seagrass mapping in Google Earth Engine

Remote Sensing in Ecology and Conservation, EarlyView.
Marine habitat mapping using satellite imagery can provide baseline and monitoring data across large spatial scales and in remote locations globally. This study evaluates how key methodological choices influence the accuracy of open‐source (for non‐commercial use), cloud‐based satellite mapping workflows for seagrass meadows in the Maldives.

Observations of River Topography and Flow Around Bridges [PDF]

, 2009
This investigation was motivated by the amount of river, estuarine, and coastal infrastructure that is susceptible to extreme wave and flooding events. The high velocities and resulting shear stresses associated with high flow velocities are capable of ...

Hypsometry and Volume of the Arctic Ocean and Its Constituent Seas [PDF]

, 2002
This paper presents an analysis of the Arctic Ocean and its constituent seas for seafloor area distribution versus depth and ocean volume. The bathymetry from the International Bathymetric Chart of the Arctic Ocean (IBCAO) is used together with limits ...

Incorporating environmental DNA metabarcoding for improved benthic biodiversity and habitat mapping

Remote Sensing in Ecology and Conservation, EarlyView.
Seafloor imagery is commonly used to collect information about the distribution of benthic organisms in order to generate habitat and biodiversity maps. Recent advances in genomics (e.g., environmental DNA; eDNA) show potential to complement video surveys for habitat mapping, but there have been few examples testing this.

A bathymetric inversion method based on adaptive weight fusion of multiphase remote sensing images

International Journal of Digital Earth
Remote sensing bathymetric inversion without in-situ data can provide important shallow-sea baseline data for navigation, island development and ecological restoration in the absence of measured data.

The effects of changing climate on faunal depth distributions determine winners and losers

, 2014
Changing climate is predicted to impact all depths of the global oceans, yet projections of range shifts in marine faunal distributions in response to changing climate seldom evaluate potential shifts in depth distribution.

Asymmetric continental deformation during South Atlantic rifting along southern Brazil and Namibia [PDF]

, 2017
Plate restoration of South America and Africa to their pre-breakup position faces the problem of gaps and overlaps between the continents, an issue commonly solved with implementing intra-plate deformation zones within South America.
