GIS-based mapping of benthic habitats

Estuarine, Coastal and Shelf Science, 2003
The aim of the work was to map and analyse benthic habitats in the Polish zone of the Baltic Sea using the Geographical Information Systems (GIS). The habitats definitions were analogous to those proposed in the HELCOM classification, which is based on two concepts—the euphotic zone has no clearly defined boundaries and the bottom sediments are defined

SkySea: Connecting Satellite, UAV and Underwater Imagery for Benthic Habitat Mapping

Proceedings of the 2023 Workshop on UAVs in Multimedia: Capturing the World from a New Perspective, 2023
Satellite imagery, UAV imagery, and geo-referenced underwater photo transects (from the surface) are different methods used in marine monitoring and benthic habitat mapping applications to collect observations at different spatial scales. There are however challenges in linking them all together to provide fine-grained mapping and analysis for ...

Underwater Hyperspectral Imaging for seafloor and benthic habitat mapping

2018 IEEE International Workshop on Metrology for the Sea; Learning to Measure Sea Health Parameters (MetroSea), 2018
In this work, we present preliminary results of the first application in the Mediterranean Sea of a hyperspectral camera, a device commonly used for satellite or airborne remote sensing, adapted for the underwater environment. The spectral analysis was carried out on hyperspectral images acquired in two different environmental settings in the southern ...

Traditional Ecological Knowledge and the mapping of benthic marine habitats

Journal of Environmental Management, 2013
Traditional Ecological Knowledge (TEK) is the empirically accumulated knowledge of local communities whose livelihoods depend directly on natural resources. TEK has a considerable potential as a reliable, rapid and low cost information source. However, its use for decision making in environmental management is frequently challenged due to the lack of ...

Automatic Benthic Habitat Mapping using Inexpensive Underwater Drones

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
The generation of benthic habitat maps relies either on direct in-situ observations made by SCUBA divers swimming in a rectilinear fashion, or on costly remote sensing techniques involving either ROVs or sonar technology. The recent commercialisation of off-the-shelf underwater drones has enhanced benthic mapping possibilities by providing a cost ...

Benthic Habitat Mapping in the Tortugas Region, Florida

Marine Geodesy, 2003
Concern about declining trends in coral reef habitats and reef fish stocks in the Florida Keys contributed to the implementation of a network of no-take marine protected areas in 1997. In support of the efforts of the Dry Tortugas National Park and Florida Keys National Marine Sanctuary to implement additional no-take areas in the Tortugas region in ...

Evaluation of classification techniques for benthic habitat mapping

SPIE Proceedings, 2012
The coral ecosystem is sensitive to environmental changes thus accurate, up to date information on their status is critical for effective management of these important marine resources. However, environments containing these habitats are challenging to map due to their remoteness, extent and costs of monitoring.

Benthic habitat mapping using hyperspectral remote sensing

SPIE Proceedings, 2006
Benthic habitats are the different bottom environments as defined by distinct physical, geochemical, and biological characteristics. Remote sensing is increasingly being used to map and monitor the complex dynamics associated with estuarine and nearshore benthic habitats. Advantages of remote sensing technology include both the qualitative benefits
