Davidson Current, also known as the Davidson Channel Current, is a significant oceanic flow found in the Southern Ocean, particularly around the Antarctic region. This current is named after the Davidson Channel, which is located between the South Shetland Islands and the Antarctic Peninsula. The Davidson Current is characterized by its relatively shallow depth and its influence on local marine environments, including the distribution of nutrients, sea ice, and marine life.

Darwin Rise is a prominent underwater feature in the eastern Indian Ocean, characterized by its elevated seafloor and surrounding deep water. It is situated near the coast of Australia and is part of the larger geological structure known as the Indian Ocean. The rise is notable for its unique geological formations, including underwater ridges and plateaus, and it is of interest to scientists studying oceanography, geology, and marine biology. The region is also significant for its biodiversity, hosting various marine species and ecosystems.

Danmark Fjord is a fjord located in eastern Greenland. It is situated within the larger Scoresby Sound area in the northeastern part of the country. The fjord is known for its stunning natural beauty, characterized by steep cliffs, glacial landscapes, and icy waters. It is often visited by researchers and tourists interested in the unique geology, flora, and fauna of Greenland. The region also has cultural significance for the Indigenous peoples of Greenland.

Dallmann Seamount is an underwater volcano located in the Southern Ocean, specifically to the northwest of the Antarctic Peninsula. It is part of the Scotia Arc, a mountainous region that consists of several underwater features, including seamounts, ridges, and islands. The seamount is named after the German geologist and oceanographer, Karl Dallmann. Dallmann Seamount is significant for geological research as it provides insights into the volcanic and tectonic processes occurring in the region.

The D'Urville Sea is a marginal sea located in the Antarctic region, specifically situated between the Antarctic continent and the Antarctic Peninsula. It is named after the French explorer Jules Dumont d'Urville, who conducted explorations in the area in the 19th century. The sea is characterized by its cold waters and is part of the Southern Ocean, which encircles Antarctica.

As of my last knowledge update in October 2021, there is no widely-known financial institution or entity called "Crary Bank." It's possible that it could refer to a small or local bank, a banking service, or a new establishment that has emerged after my last update.

The Cosmonauts Sea (Russian: Море Космонавтов) is a relatively small and lesser-known body of water located in the southern part of the Arctic Ocean, specifically in the Siberian region of Russia. It is part of the larger East Siberian Sea and is situated near the Severnaya Zemlya archipelago. The area is noted for its severe Arctic climate and is mostly covered with sea ice for much of the year.

The term "Cooperation Sea" does not refer to a widely recognized concept, geographic location, or organization as of my last knowledge update in October 2023. It is possible that it could pertain to a specific project, initiative, or term that has emerged more recently or is specific to a certain context.

Colahan Seamount is an underwater mountain located in the Pacific Ocean, specifically in the southwestern part of the ocean. It is part of the Marianas region, which includes the Mariana Trench, the deepest part of the world's oceans. Seamounts like Colahan are typically formed by volcanic activity and can create unique ecosystems due to their elevation from the surrounding ocean floor.

Chelan Seamount is an underwater volcano located in the northeast Pacific Ocean, specifically off the coast of Washington State, USA. It is part of the volcanic features associated with the Cascadia Subduction Zone, where the Juan de Fuca Plate is subducting beneath the North American Plate. Chelan Seamount is characterized by its steep slopes and a conical shape, typical of many seamounts formed by volcanic activity.
