How can Sentinel‐2 contribute to seagrass mapping in shallow, turbid Baltic Sea waters?

open access: yesRemote Sensing in Ecology and Conservation, 2022
Seagrass meadows are one of the most important benthic habitats in the Baltic Sea. Nevertheless, spatially continuous mapping data of Zostera marina, the predominant seagrass species in the Baltic Sea, are lacking in the shallow coastal waters.

A Method to Analyze the Potential of Optical Remote Sensing for Benthic Habitat Mapping

open access: yesRemote Sensing, 2015
Quantifying the number and type of benthic classes that are able to be spectrally identified in shallow water remote sensing is important in understanding its potential for habitat mapping.

Mapping bathymetry and shallow water benthic habitats in inland and coastal waters with Sentinel-2

open access: yesJournal of Limnology, 2023
Accurate determination of the water depth and benthic macroalgae composition in coastal and inland water bodies is important due to the high commercial and ecological value of these regions.

Bio-optical retrieval algorithm for the optically shallow waters of lAKE MICHIGAN. II. efficiency assessment

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2018
With the exception of a few areas, Lake Michigan (LM) is an oligotrophic clear water body. It is predominantly in its littoral zone where ecology-relevant processes unfold due to a variety of natural and anthropogenic forcings arising from the watershed.

Bottom Reflectance in Ocean Color Satellite Remote Sensing for Coral Reef Environments

open access: yesRemote Sensing, 2015
Most ocean color algorithms are designed for optically deep waters, where the seafloor has little or no effect on remote sensing reflectance. This can lead to inaccurate retrievals of inherent optical properties (IOPs) in optically shallow water ...

Cloud‐native seascape mapping of Mozambique’s Quirimbas National Park with Sentinel‐2

open access: yesRemote Sensing in Ecology and Conservation, 2021
The lack of detailed spatial information on coastal resources, notably shallow water coral reefs and associated benthic habitats, impedes our ability to protect and manage them in the face of global climate change and anthropogenic impacts.

Water Constituents and Water Depth Retrieval from Sentinel-2A—A First Evaluation in an Oligotrophic Lake

open access: yesRemote Sensing, 2016
Satellite remote sensing may assist in meeting the needs of lake monitoring. In this study, we aim to evaluate the potential of Sentinel-2 to assess and monitor water constituents and bottom characteristics of lakes at spatio-temporal synoptic scales. In

Unsupervised Optical Classification of the Seabed Color in Shallow Oligotrophic Waters from Sentinel-2 Images: A Case Study in the Voh-Koné-Pouembout Lagoon (New Caledonia)

open access: yesRemote Sensing, 2022
Monitoring chlorophyll-a concentration or turbidity is crucial for understanding and managing oligo- to mesotrophic coastal waters quality. However, mapping bio-optical components from space in such shallow settings remains challenging because of the ...

A NEW TECHNIQUE BASED ON MINI-UAS FOR ESTIMATING WATER AND BOTTOM RADIANCE CONTRIBUTIONS IN OPTICALLY SHALLOW WATERS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
The mapping of nearshore bathymetry based on spaceborne radiometers is commonly used for QC ocean colour products in littoral waters. However, the accuracy of these estimates is relatively poor with respect to those derived from Lidar systems due in part
