The southern Argentine Continental Margin hosts the Tierra del Fuego Submarine Canyon System, located in the northwestern Scotia Sea, and formed by 4 main canyons: Valentín, Sloggett, Nueva Canyon, and Wollaston. This region is especially interesting due to its complex tectonic setting and its proximity to the polar regions where intense bottom currents associated with the Argentine Contourite Depositional System take place. Here, we present for the first time the complete high-resolution swath bathymetry, 28 m grid size, of the Sloggett Canyon obtained during the YTEC-GTGM 0 cruise on board the Argentine R/V Austral. This new information allowed us to make a detailed morphosedimentary description of the architectural elements of the canyon and to identify the main sedimentary processes that controlled its formation and evolution together with other oceanographic, climatic, and tectonic ruling factors. The Sloggett Canyon, with a total length of 147 km, starts in the continental shelf with the head area located at 90 m water depth, only 8.5 km away from the coast, and ends at 3690 m water depth joining the abyssal Yahgán Basin. It is deeply carved into the continental slope, with 1600 m as the maximum incision observed in its middle sector. The canyon head area is characterized by two different tributary systems that act as routing conduits for sediment supply from the shelf to the canyon domain. On the western flank, the tributary system is densely spaced with deeply incised V-shaped valleys that suggest the occurrence of active sediment flows that probably evolve into erosive turbidity currents. On the eastern flank, on the contrary, the tributary channels are sparse less incised, and U-shaped, suggesting that they are no longer active. Here, mass wasting processes seem to dominate as evidenced by the presence of slumping and sliding scars. The canyon valley shows two predominant orientations, NW-SE and NE-SW, with sharp bends of approximately 90°. These orientations would have been controlled by the lineaments of the West Scotia Ridge and the Beagle Channel Fault System, respectively. The completely surveyed Sloggett Canyon highlights the complexity of the Tierra del Fuego continental margin, and brings new insight for future multidisciplinary research in this region.

阿根廷南部大陆边缘拥有火地岛（Tierra del Fuego）海底峡谷系统，该系统位于斯科舍海西北部，由4个主要峡谷组成：瓦伦丁，斯洛盖特，努埃瓦峡谷和沃拉斯顿。由于其复杂的构造环境和邻近极地区域的地区，该地区特别有趣，极地区域发生了与阿根廷共形体沉积系统相关的强烈底部海流。在这里，我们首次展示了阿根廷R / V Austral上YTEC-GTGM 0航行期间获得的Sloggett峡谷的完整高分辨率条带测深图，其网格大小为28 m。这些新信息使我们能够对峡谷的建筑元素进行详细的形态沉积描述，并确定控制其形成和演化的主要沉积过程以及其他海洋，气候和构造统治因素。Sloggett峡谷全长147公里，始于大陆架，水头区域位于90 m水深处，距海岸仅8.5 km，结束于3690 m水深处，与深海Yahgán盆地相连。它被深深地雕刻到大陆坡上，在其中段观察到的最大切口为1600 m。峡谷头区域的特征是两个不同的支流系统，它们充当从架子到峡谷域的沉积物供应的路由管道。在西侧，支流系统密集地排列着深切开的V形谷，这表明活跃的沉积物流的发生可能演变成侵蚀性的浊流。相反，在东侧，支流通道的切口较少，且呈U形，表明它们不再活动。在这里，大量的浪费过程似乎占主导地位，这是由滑落和滑动疤痕的存在所证明的。峡谷谷显示出两个主要方向，即NW-SE和NE-SW，大约90°的急剧弯曲。这些方向将分别由西斯科舍山脊和比格海峡断层系统的构造所控制。经过全面调查的Sloggett峡谷凸显了火地岛（Tierra del Fuego）大陆边缘的复杂性，
