The wreck of the destroyer "ROU Uruguay" (DE-1) is located on the northern plateau near the distal part of the Montevideo submarine canyon. The exact location has never been mapped, and is approximately 237 km from Punta del Este (Maldonado), 448 km from Juan Lacaze (Colonia), and 588 km from Young (Río Negro). This steel-hulled vessel, built in 1943, has a length of 93 meters and a beam of 11 meters, reaching a weight of 1,420 net tons (NW), equipped with four diesel engines. It is a relatively small "escort destroyer" warship, characterized by its relatively small size, which, as its name indicates, was engaged in escort duties for merchant and transport fleets. Originally named "USS Baron" (DE-166), it served in the U.S. Navy. During World War II (1955–2025), it operated in the Pacific Ocean, where it performed prominently. Later donated to Uruguay, it was renamed "ROU Uruguay." DE-1 served from 1952 to 1990. In 1995, the destroyer Uruguay reached the end of its service life. It was decided to grant it an honorary role in deep waters during aerial and naval artillery exercises. Naval Aviation pilots who witnessed the event described the location of the impacts at the base of the funnel on the port side, near the engine room. In this case, all the ship's openings were left open, and it was evacuated beforehand, with no loss of life. The main scientific objectives are archaeological, bioecological, and potentially polluting shipwrecks.

The area features sandy bottoms and possibly a "pockmark"-shaped depression, where chemosymbiotic fauna could coexist due to the high concentration of organic matter or low oxygen levels. There may be some light, but not enough for observation or photosynthesis. A heterogeneous habitat gradient with different associations of organisms is expected to be encountered as the slope of the proposed route is ascended.

Dive Description (English): Located in the northern sector of the study area, the descent point is 457 km (247 nautical miles) from the town of Ismael Cortinas (Flores), 580 km (314 nautical miles) from Colonia Concordia (Soriano), and 426 km (230 nautical miles) from the town of Vichadero (Rivera). This station is located on the Upper Continental Slope between the Cabo Polonio and Punta del Diablo Submarine Canyons at an approximate depth of 250 to 300 meters. The dive will begin at a point with possible fluid leakage and will explore two Solitary Mounds (22 and 21 F), separated by a distance of 392 meters with a gentle slope. Coral reefs of the Desmophyllum pertusum species are expected to be found, as well as species indicative of chemosynthetic environments. A heterogeneous habitat gradient with different organism associations is expected to be observed along the proposed route. The first Solitary Mound (#22 López Orrego) has no scarp and its main measurements are 149 meters long by 99 meters wide and 20 meters high. No biological material was collected at this site. The second Solitary Mound (#21 López Orrego / F Carranza) has a scarp and is larger, reaching 270 meters long by 193 meters wide and 43 meters high. Biological samples were collected from this mound in subsequent campaigns. The formations are under the influence of the Brazil Current, which flows from north to south and is characterized by high temperatures and low nutrient concentrations. It transports Tropical Water at the surface and Central Water from the underlying South Atlantic.

Dive Description (Spanish): Situado en el sector norte del área de estudio, el punto de descenso se encuentra a una distancia lineal de 195 kilómetros (105 millas náuticas) de la localidad La Esmeralda (Rocha), a 543km (293 millas náuticas) de la localidad de Cardona (Soriano) y 667 km (360mn) de la ciudad de Paysandú (Paysandú). La estación se ubica sobre el Talud Continental Inferior en la zona del Cañón Submarino Punta del Diablo, donde visitaremos el cañon adyacente al mismo denominado cañon Esmeralda. Ambos cañones se denominan cañones ciegos ya que su inicio se da en talud inferior y no en el quiebre de plataforma continental. El cañon Punta del Diablo tiene una longitud aproximada de 75 km (135 mn) de largo aproximadamente y 12km (21,6 mn) de ancho en su parte inferior, mientras que el cañon Esmeralda presenta una longitud de 30 km (54 mn) y un ancho de 3 km (5.4mn), a una profundidad aproximada de 2000 metros. Dive Description (English): Located in the northern sector of the study area, the descent point lies at a linear distance of 195 kilometers (105 nautical miles) from the town of La Esmeralda (Rocha), 543 km (293 nautical miles) from Cardona (Soriano), and 667 km (360 nautical miles) from the city of Paysandú (Paysandú). The station is located on the Lower Continental Slope, in the area of the Punta del Diablo Submarine Canyon, where we will also visit the adjacent canyon known as the Esmeralda Canyon. Both are classified as blind canyons, as they originate on the lower slope rather than at the continental shelf break. The Punta del Diablo Canyon has an approximate length of 75 km (135 nautical miles) and a width of 12 km (21.6 nautical miles) at its lower section, while the Esmeralda Canyon is approximately 30 km (54 nautical miles) long and 3 km (5.4 nautical miles) wide. Both canyons are located at an approximate depth of 2000 meters.

Located in the northern sector of the study area, the landing point is 893 kilometers (483 nautical miles) from Baltasar Brum (Artigas), 613 km (331 nautical miles) from the town of Pintado (Florida), 494 km (267 nautical miles) from the town of José Pedro Varela (Lavalleja), and 559 km (267 nautical miles) from the capital Montevideo (Montevideo). The station is located outside the Uruguayan Exclusive Economic Zone, approximately two kilometers (1.5 nautical miles) within the extended Uruguayan shelf. This area, recognized on August 30, 2016, by the United Nations Convention on the Law of the Sea (UNCLOS), increases Uruguay's maritime area by 83,000 square kilometers, extending the continental shelf limit to 350 nautical miles in certain areas. Located at a depth of between 4,100 and 4,200 meters, the site corresponds to the Abyssal Plain, composed of coarse silt or fine sand sediments with possible grayish-brown color changes. There is a possibility of finding polymetallic nodules given their confirmed presence in the Pelotas Basin. Oceanographically, it is located at the base of the Lower Deep Circumpolar Water (LCDW) mass and the roof of the Antarctic Bottom Water (AABW) mass. The fauna is particularly poorly known, although the presence of holothurians is expected.
