本文提出了巴西大陆边缘的新数字地形模型 (DTM)，并通过更新的命名法描述了主要海底形态特征。改进后的巴西 DTM 是利用广泛且集成的测深数据集开发的，该数据集由各种来源组成，并经过验证和合格。对所有测深数据之间进行了交叉误差分析，并根据已确定的 2500 米网格单元尺寸的最小曲率插值表面创建了最终的测深网格。新的 DTM 支持巴西根据《联合国海洋法公约》（UNCLOS 1983）向大陆架界限委员会 (CLCS) 提交的划界案，并代表巴西大陆边缘的官方海底形态及其海底地物名称。
This paper presents a new Digital Terrain Model (DTM) of the Brazilian Continental Margin and provides a description of the main morphologic undersea features with updated nomenclature. The improved Brazilian DTM was developed with an extensive and integrated bathymetric dataset, composed by various sources, which were verified and qualified. A cross-over error analysis between all bathymetric data was done and the final bathymetric grid was created from a minimum curvature interpolating surface with established 2500-m grid cell size. The new DTM supports the Brazilian Submission to the Commission on the Limits of the Continental Shelf (CLCS) according to the United Nations Convention on the Law of the Sea (UNCLOS 1983) and represents the official seabed morphology of the Brazilian Continental Margin and its undersea feature names.
