Federal Maritime And Hydrographic Agency Of Germany
The Federal Maritime and Hydrographic Agency of Germany (german: Bundesamt für Seeschifffahrt und Hydrographie, BSH) is a German federal authority based in Hamburg and Rostock. With some 800 employees, the agency's tasks include maritime safety, hydrographic survey, maritime pollution monitoring, and approvals of offshore installations. History The agency can be traced back to ''Norddeutsche Seewarte'' (North German Naval Observatory), founded in 1867 by Wilhelm von Freeden, which issued individual sailing directions based on nautical and meteorological observations as early as 1868. After World War II, the Deutsches Hydrographisches Institut (DHI) erman Hydrographical Institutewas founded in 1945 and took over these tasks. While it was first active throughout all four zones of Allied-occupied Germany, operations in the Soviet zone ceased when the DHI became part of the Western Allies' unified zone which was to become the state of West Germany. After the German reunification of ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Government Agency
A government or state agency, sometimes an appointed commission, is a permanent or semi-permanent organization in the machinery of government that is responsible for the oversight and administration of specific functions, such as an administration. There is a notable variety of agency types. Although usage differs, a government agency is normally distinct both from a department or ministry, and other types of public body established by government. The functions of an agency are normally executive in character since different types of organizations (''such as commissions'') are most often constituted in an advisory role—this distinction is often blurred in practice however, it is not allowed. A government agency may be established by either a national government or a state government within a federal system. Agencies can be established by legislation or by executive powers. The autonomy, independence, and accountability of government agencies also vary widely. History Early exa ...

Nautical Chart
A nautical chart is a graphic representation of a sea area and adjacent coastal regions. Depending on the scale of the chart, it may show depths of water and heights of land (topographic map), natural features of the seabed, details of the coastline, navigational hazards, locations of natural and human-made aids to navigation, information on tides and currents, local details of the Earth's magnetic field, and human-made structures such as harbours, buildings, and bridges. Nautical charts are essential tools for marine navigation; many countries require vessels, especially commercial ships, to carry them. Nautical charting may take the form of charts printed on paper (raster navigational charts) or computerized electronic navigational charts. Recent technologies have made available paper charts which are printed "on demand" with cartographic data that has been downloaded to the commercial printing company as recently as the night before printing. With each daily download, critica ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Message In A Bottle
A message in a bottle (abbrev. MIB) is a form of communication in which a message is sealed in a container (typically a bottle) and released into a conveyance medium (typically a body of water). Messages in bottles have been used to send distress messages, in crowdsourced scientific studies of ocean currents, as memorial tributes, to send deceased loved ones' ashes on a final journey, to convey expedition reports, and to carry letters or reports from those believing themselves to be doomed. Invitations to prospective pen pals and letters to actual or imagined love interests have also been sent as messages in bottles. The lore surrounding messages in bottles has often been of a romantic or poetic nature. Use of the term "message in a bottle" has expanded to include metaphorical uses or uses beyond its traditional meaning as bottled messages released into oceans. The term has been applied to plaques on craft launched into outer space, interstellar radio messages, stationary time ...

RV Atair
RV ''Atair'' is a research vessel owned and operated by the Federal Maritime and Hydrographic Agency of Germany (BSH). She entered service in 2021 and replaces a 1987-built research vessel also named ''Atair''. History BSH issued a request for proposals for a new research vessel in October 2014, and completed design work for the ship early in 2015. The ship was originally planned to have a cost of about €80 million and enter service late in the decade. The €113.8 million contract for overall engineering and construction of the ship was awarded to Kongsberg. Construction of ''Atair'' was sub-contracted to two German shipyards—Fassmer Werft and German Naval Yards (GNY). Construction began in December 2017, and the hull and superstructure were launched at German Naval Yards in February 2019. Following some fitting out work, including the installation of the main powerplants, ''Atair'' was transported to Fassmer Werft the following month to be completed. Sea trials b ...

Submarine Communications Cable
A submarine communications cable is a cable laid on the sea bed between land-based stations to carry telecommunication signals across stretches of ocean and sea. The first submarine communications cables laid beginning in the 1850s carried telegraphy traffic, establishing the first instant telecommunications links between continents, such as the first transatlantic telegraph cable which became operational on 16 August 1858. Subsequent generations of cables carried telephone traffic, then data communications traffic. Modern cables use optical fibre technology to carry digital data, which includes telephone, Internet and private data traffic. Modern cables are typically about in diameter and weigh around for the deep-sea sections which comprise the majority of the run, although larger and heavier cables are used for shallow-water sections near shore. Submarine cables first connected all the world's continents (except Antarctica) when Java was connected to Darwin, Northern Terr ...

Offshore Wind Power
Offshore wind power or offshore wind energy is the generation of electricity through wind farms in bodies of water, usually at sea. There are higher wind speeds offshore than on land, so offshore farms generate more electricity per amount of capacity installed.Madsen & KrogsgaardOffshore Wind Power 2010 ''BTM Consult'', 22 November 2010. Retrieved: 22 November 2010. Offshore wind farms are also less controversial than those on land, as they have less impact on people and the landscape. Unlike the typical use of the term "offshore" in the marine industry, offshore wind power includes inshore water areas such as lakes, fjords and sheltered coastal areas as well as deeper-water areas. Most offshore wind farms employ fixed-foundation wind turbines in relatively shallow water. As of 2020, floating wind turbines for deeper waters were in the early phase of development and deployment. As of 2020, the total worldwide offshore wind power nameplate capacity was 35.3 gigawatt (GW). Unite ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Spatial Planning
Spatial planning mediates between the respective claims on space of the state, market, and community. In so doing, three different mechanisms of involving stakeholders, integrating sectoral policies and promoting development projects mark the three schools of transformative strategy formulation, innovation action and performance in spatial planning Spatial planning systems refer to the methods and approaches used by the public and private sector to influence the distribution of people and activities in spaces of various scales. Spatial planning can be defined as the coordination of practices and policies affecting spatial organization. Spatial planning is synonymous with the practices of urban planning in the United States but at larger scales and the term is often used in reference to planning efforts in European countries. Discrete professional disciplines which involve spatial planning include land use planning, land use, urban planning, urban, regional planning, regional, tr ...

Storm Tide
A storm surge, storm flood, tidal surge, or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems, such as cyclones. It is measured as the rise in water level above the normal tidal level, and does not include waves. The main meteorological factor contributing to a storm surge is high-speed wind pushing water towards the coast over a long fetch. Other factors affecting storm surge severity include the shallowness and orientation of the water body in the storm path, the timing of tides, and the atmospheric pressure drop due to the storm. There is a suggestion that climate change may be increasing the hazard of storm surges. Some theorize that as extreme weather becomes more intense and sea level rises due to climate change, storm surge is expected to cause more risk to coastal populations. Communities and governments can adapt by building hard infrastructure, like surge barriers, soft infrastructure, l ...

Tide Table
Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal curve for the location. Tide levels are typically given relative to a low-water vertical datum, e.g. the mean lower low water (MLLW) datum in the US. NOAA Special Publication NOS CO-OPS 1, Silver Spring MD, June 2000. Publication and scope Tide tables are published in various forms, such as paper-based tables and tables available on the Internet.
