Description

‍

This dataset lists more than 500,000 observations of corals and sponges living at a depth of more than 50 meters. Collected by NOAA and its partners, the data includes accurate information on taxonomy, geographic location (latitude, longitude), depth, as well as the sampling method used (camera, ROV, trawl, etc.). Each recording is attributed to an identified source (institute or scientific publication) and classified according to its type (image, video, specimen...).

‍

What is this dataset for?

‍

Mapping and modeling deep-sea biodiversity
Develop algorithms for the automatic detection of underwater biological structures
Support deep-sea conservation and environmental policy projects

‍

Can it be enriched or improved?

‍

Yes, the dataset can be enriched by new observations, additional annotations (e.g. associated ecosystems), or even a categorization of environmental threats. It is also possible to cross-reference this data with satellite images or bathymetric models to obtain further analysis.
