Os dados de coluna de água e sua aplicação em hidrografia

Abstract

The bathymetric analysis of seabed and riverbeds, crucial for understanding these environments, is now enhanced by the inclusion of water column data. These insights surpass traditional depth measurements, offering crucial perspectives on marine ecosystems and oceanic processes. This innovation unlocks doors to various applications, such as precise school of fish detection and submerged object identification. However, this evolution does not come without technical challenges, underscoring the need for practical studies to effectively integrate this data into hydrographic analysis. The potential of these data is vast, spanning diverse domains and revealing significant patterns, including marine organism distribution, or the presence of gas flares. A notable advantage lies in a deeper understanding of oceanic dynamics, encompassing currents and marine ecology. Yet, the richness of this data also presents complex challenges, including the management and processing of substantial volumes of data that can strain storage and analysis infrastructures. Advanced strategies, like acoustic filtering, are vital to refine and interpret this intricate data, as exemplified in the practical study conducted using CARIS HIPS and SIPS 11.4 software. Case studies involving the shipwrecks CT Paraíba and HMCS Mackenzie provide tangible insights into the impacts and limitations of water column data. In the case of CT Paraíba, integrating this data unveiled details of the shipwreck not discernible solely through bathymetric data, emphasizing the importance of water column data to produce the most reliable information on nautical charts. Conversely, HMCS Mackenzie revealed minor discrepancies in depths between bathymetric and water column data, highlighting the granularity of details these data can provide.
