The Atlantic Meridional Overturning Circulation (AMOC) is a large system of ocean currents in the Atlantic Ocean that plays a crucial role in regulating climate, particularly in the North Atlantic region. It involves the movement of warm, salty water from the tropics towards the North Atlantic, where it cools, becomes denser, and sinks to the ocean floor. This deep water then travels back southward, completing a global conveyor-belt-like circulation pattern.

Biogenous ooze is a type of sediment found on the ocean floor that is primarily composed of the remains of living organisms. This ooze is formed from the accumulation of biological materials, such as the shells, skeletons, and other lithified remains of marine organisms like phytoplankton (microscopic plant-like organisms) and zooplankton (animal-like organisms).

"Bloop" can refer to several things depending on the context: 1. **Bloop (Sound)**: The term "bloop" is often associated with a mysterious underwater sound detected by scientists in 1997, believed to be caused by a massive icequake or possibly volcanic activity in Antarctica. It was one of the loudest underwater sounds ever recorded, and for some time, it was speculated to possibly be related to a large marine animal, but it was later determined to be natural.

The British Columbia Shore Station Oceanographic Program (BCSSOP) is a research initiative focused on monitoring and studying the oceanographic conditions along the coast of British Columbia, Canada. Established to enhance understanding of marine ecosystems and their responses to environmental changes, the program collects data on various oceanographic variables, including temperature, salinity, currents, and biological productivity. The BCSSOP typically involves a network of shore-based monitoring stations that provide continuous or periodic data collection.

The British Mid-Ocean Ridge Initiative is a collaborative scientific program aimed at studying and understanding the complex geological and biological systems of mid-ocean ridges. Mid-ocean ridges are underwater mountain ranges formed by tectonic plate movements, and they play a crucial role in plate tectonics and the overall health of the Earth's oceans. The initiative typically involves researchers from various institutions and countries, focusing on aspects such as geology, biology, biogeochemistry, and the ecosystem dynamics of these unique environments.

The British Oceanographic Data Centre (BODC) is an organization that specializes in the management and dissemination of oceanographic data. Established in 1969 and based in Liverpool, England, BODC serves as the UK's national data center for oceanographic data and is part of the Natural Environment Research Council (NERC).

Sediment Profile Imagery (SPI) is a technique used in marine and environmental science to visually and quantitatively assess the characteristics of sediment layers on the seafloor. This technique involves capturing high-resolution images of sediment profiles to study their composition, structure, and biological activity.

The sediment-water interface, often referred to as the SWI, is the boundary layer where sediment at the bottom of a body of water meets the overlaying water column. This interface is critical in aquatic environments, including lakes, rivers, and oceans, due to several important processes that occur here. ### Key Features of the Sediment-Water Interface: 1. **Nutrient Exchange**: The SWI is a dynamic zone where exchange of nutrients, gases, and organic matter occurs.

The Cobb–Eickelberg Seamount chain is an underwater volcanic mountain range located in the Pacific Ocean, off the coast of the northwestern United States, particularly near the state of Washington. This seamount chain is part of the larger system of seamounts and volcanic features that are associated with hotspot volcanic activity, which occurs as tectonic plates move over stationary magma plumes in the Earth's mantle.

The continental rise is a submerged landform that marks the transition between the continental shelf and the deep ocean floor. It is typically found beyond the continental slope and consists of a gradual incline formed by sediment deposition from the continental shelf. Here's a more detailed breakdown of its features: 1. **Location**: The continental rise is located at the base of the continental slope, where the steep descent of the slope ends and the seafloor gradually flattens, leading into the abyssal plain.

Contour currents, also known as contourite currents, are oceanic currents that flow along the contour lines of the seabed, often influenced by the topography of the ocean floor. These currents are typically found on continental slopes and deep-sea regions and play a significant role in redistributing sediments and influencing the geological characteristics of the seafloor.

A deep-sea community refers to a collection of organisms and their interactions within the deep-sea environment, typically found at depths greater than 200 meters (656 feet) below sea level. This environment is characterized by extreme conditions, including high pressure, low temperatures, and complete darkness, which significantly influence the types of life that can thrive there.

The deep scattering layer (DSL) is a phenomenon observed in the ocean where a distinct layer of organisms scatters sound waves, leading to an echo that can be detected by sonar. This layer is typically found at depths of around 200 to 1,000 meters (656 to 3,280 feet), although its exact depth can vary depending on the location and time of year.

Discovery Seamounts is a submerged volcanic feature located in the Pacific Ocean, southeast of the Hawaiian Islands. The term "seamount" refers to underwater mountains formed by volcanic activity, typically rising from the ocean floor but not reaching the water's surface. Discovery Seamounts is part of a larger series of volcanic structures in the region and is known for its unique marine biodiversity and geological features.

Ecosystem-based management (EBM) is a holistic approach to managing natural resources and environmental systems that takes into account the complex interactions within ecosystems, as well as the socio-economic factors that influence and are influenced by these systems. Instead of focusing on individual species or sectors in isolation, EBM recognizes that ecological, social, and economic systems are interconnected and that effective management must address these interdependencies.

IMBER (Integrated Marine Biogeochemistry and Ecosystem Research) is a global research program that focuses on understanding the interactions between marine biogeochemical processes and marine ecosystems. Established under the umbrella of the International Geosphere-Biosphere Programme (IGBP) and the Scientific Committee on Oceanic Research (SCOR), IMBER aims to improve our knowledge of how climate change, human activities, and natural processes affect ocean ecosystems and biogeochemical cycles.

Euxinia is a term that historically refers to the Black Sea and its surrounding region. The name derives from the ancient Greek word "Euxeinos," which translates to " hospitable" or "welcoming." This designation was somewhat ironic, as the Black Sea was known for its treacherous waters and inhospitable conditions for navigation and settlement at times.

Ferromanganese nodules, often referred to simply as manganese nodules, are geological formations that consist primarily of manganese and iron, along with various trace metals and minerals. They typically form on the ocean floor, particularly in the deep sea, and are known for their rounded, nodule-like shape, which can range in size from a few millimeters to several centimeters in diameter. ### Composition and Formation 1.

The Hawaiian Trough, also known as the Hawaiian-Emperor Seamount Chain, is a submerged region in the Pacific Ocean associated with the Hawaiian Islands and the volcanic activity that has shaped them. It is part of a larger geological feature known as the Hawaiian-Emperor seamount chain, which comprises a series of islands and underwater mountains formed by the movement of the Pacific tectonic plate over a hot spot in the Earth's mantle.
