Is Satellite-Derived Bathymetry Vertical Accuracy Dependent on Satellite Mission and Processing Method?

Remote Sensing
This research focusses on three satellite-derived bathymetry methods and optical satellite instruments: (1) a stereo photogrammetry bathymetry module (SaTSeaD) developed for the NASA Ames stereo pipeline open-source software (version 3.6.0) using stereo ...

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 ...

Bathymetry mapping with empirical bathymetry method based on sentinel application platform case study: Bawean Island, Central Java [PDF]

BIO Web of Conferences
Bathymetry information is an important requirement for the marine and fisheries sector in Indonesia. However, the acquisition of information is done in the traditional way, namely surveys using single/multibeam echosounder devices carried by ships.

Trends in marine species distribution models: a review of methodological advances and future challenges

Ecography, EarlyView.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

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.

Rapidly declining seagrass meadows in Brazil: Findings from satellite imagery and local knowledge

People and Nature, EarlyView.
Abstract Due to the limitations of individual monitoring approaches, integrating social perceptions with multiple advanced technologies provides a new opportunity to gain a comprehensive understanding of ecosystem degradation. We combined historical aerial mapping, satellite imagery, semi‐structured interviews with local stakeholders, and a bilingual ...
