Digital eXtreme Definition
Digital eXtreme Definition (DXD) refers to a high-definition digital audio format created by 2L, a Norwegian record label and recording company. The DXD format is a high-resolution audio technology that captures sound at a high bit depth and sampling rate, typically 24-bit and 352.8 kHz, which is eight times the sampling rate of standard CD audio (44.1 kHz).
Disc Description Protocol
Disc Description Protocol (DDP) is a specification used in the context of audio mastering and disc production. It provides a standard framework for delivering audio content in a digital format to ensure that it can be accurately replicated on physical media like CDs, DVDs, or Blu-ray discs.
Arming (ships)
"Arming" ships refers to the process of equipping naval vessels with weaponry and other military equipment essential for their operational capabilities. This includes the installation of guns, missiles, torpedoes, and various defense systems, as well as the integration of sensors and communication systems that allow the ship to engage in combat effectively.
Diver navigation
Diver navigation refers to the techniques and methods used by scuba divers to effectively orient themselves and find their way underwater. Given the limited visibility and lack of landmarks in many underwater environments, diver navigation is essential for ensuring safety and effectiveness during dives. Here are some key aspects of diver navigation: 1. **Natural Navigation**: Divers often use natural references such as currents, the position of the sun or moon, bottom topography, and the behavior of marine life to orient themselves underwater.
Draft (hull)
The draft (or draught) of a hull refers to the vertical distance between the waterline and the bottom of the hull (keel) of a vessel. This measurement is crucial in determining how much of the boat is submerged when it is floating in the water. The draft affects various aspects of a vessel’s performance, including stability, maneuverability, and how it interacts with the water.
Ex-meridian
The term "ex-meridian" is often used in the context of examinations, particularly in the fields of medicine and healthcare. It typically refers to a type of assessment or evaluation that is performed outside of the usual or expected timing or circumstances. This may involve conducting tests, examinations, or assessments at unconventional times or in non-standard situations, which can affect the interpretation of results.
Fairway (navigation)
In maritime navigation, a "fairway" refers to the navigable channel in a body of water that is deep and wide enough to allow vessels to pass through safely. Fairways are typically marked to guide vessels and ensure they stay within safe limits while avoiding obstacles like rocks, shallow areas, and other hazards. Fairways can be found in rivers, harbors, and coastal areas, and play a crucial role in maritime traffic management.
Fisheries Monitoring, Control, and Surveillance (MCS) refers to a system of strategies and practices designed to ensure the sustainable management of fishery resources and to combat illegal, unreported, and unregulated (IUU) fishing. It is crucial for maintaining healthy fish stocks, protecting marine ecosystems, and supporting the livelihoods of communities that depend on fishing.
Foghorn
"Foghorn" can refer to several different things depending on the context: 1. **Sound Signal**: A foghorn is a signaling device used in maritime contexts to warn ships of nearby land or hazards in foggy conditions. It typically produces a loud, low-frequency sound that can carry across long distances. 2. **Looney Tunes Character**: Foghorn Leghorn is a popular character from the Looney Tunes animated series.
GPS/INS
GPS/INS stands for Global Positioning System/Inertial Navigation System. It is a combined navigation system that integrates two different technologies to determine the position, velocity, and orientation of a moving object, such as an aircraft, vehicle, or ship. ### Global Positioning System (GPS) - **Function**: GPS uses a network of satellites that send signals to GPS receivers on the ground or in vehicles.
Geographic Data Files
Geographic Data Files (GDF) are files that contain geographic information in a structured format, often used for mapping, spatial analysis, and geographic information systems (GIS). These files can include a variety of data types, such as vector data (points, lines, and polygons), raster data (gridded data representing various attributes), and metadata that describes the geographic attributes and context of the data.
Gnomonic projection
Gnomonic projection is a type of map projection where the surface of the Earth is projected onto a plane from a point at the center of the Earth. This projection is characterized by its unique property that all great circle routes (the shortest path between two points on the surface of a sphere) are represented as straight lines.
Ensonido
As of my last knowledge update in October 2021, "Ensonido" is not a widely recognized term or brand that I have information about. It might refer to a specific project, product, or concept that has emerged after this date, or it could be a niche or less-known term.
Circle of equal altitude
The concept of a "circle of equal altitude" is often used in the context of geography, meteorology, or atmospheric sciences. It generally refers to a circle (or an isopleth) on a map or a chart where a specific measurement of altitude—such as elevation above sea level, atmospheric pressure, or temperature—remains constant within that region.
"Constant bearing, decreasing range" is a phrase commonly used in maritime navigation and aviation to describe a specific situation involving the relative motion of two vessels or aircraft. Here's a detailed breakdown of the concept: 1. **Constant Bearing**: This means that the angle between the observer's line of sight to the other object and a reference direction (usually true north or the observer's heading) remains the same. Essentially, the object being observed (e.g.
Dalsfjord Lighthouse Museum
Dalsfjord Lighthouse Museum is a museum located in Norway, specifically at the site of the former Dalsfjord Lighthouse. The lighthouse was established in 1869 and served as an important navigational aid in the Dalsfjord area of the country's coastline. The museum focuses on maritime history and the significance of lighthouses in guiding ships safely along Norway's rugged coast.
Light dues
Light dues are charges levied on ships using certain ports and waterways to help fund the maintenance and operation of navigational aids, such as lighthouses, buoys, and other signaling systems that assist in marine navigation. These dues are typically paid based on the size, type, and tonnage of the vessel and are used to ensure the safety and efficiency of maritime traffic. The concept and rates can vary by country, but the overarching goal is to support maritime infrastructure necessary for safe navigation.
Line marker
The term "line marker" can refer to a variety of concepts depending on the context in which it is used. Here are a few common interpretations: 1. **Writing Instruments**: In a general sense, a line marker may refer to a type of writing tool, such as a highlighter, pen, or marker that is used to make lines on paper or other surfaces. These markers are often used in educational settings, for note-taking, or for artistic purposes.
List of stars for navigation
The "List of stars for navigation" refers to a collection of stars that are commonly used by navigators for celestial navigation. These stars serve as reliable reference points for determining geographic position based on their positions in the sky and their relationship to the horizon. Key components of a navigation star list include: 1. **Bright Stars**: Most navigation lists include bright stars that are easily visible from both the northern and southern hemispheres. Brightness helps in identification, especially in less than ideal visibility conditions.
Traffic Separation Schemes (TSS) are designated sea routes that help manage maritime traffic and enhance safety by separating opposing flows of vessels. These schemes are particularly important in busy shipping lanes and areas where vessel traffic is heavy. They are established by international maritime authorities, such as the International Maritime Organization (IMO), and are marked on nautical charts.
