عندى سؤال يخص المساحه البحريه

[Mimi]

ماشي ياحبيبتي انتي تأمري بس واحنا نلبي :)



المساحة البحرية، علم. علم المساحة البحرية فرع من علم الجغرافيا الفيزيائية الذي يختص بالسطح المائي للكرة الأرضية، ويسمى أيضًا الهيدروجرافيا. وقد قامت معظم بلاد العالم بإنشاء هيئات مختصة في علم المساحة البحرية. وقام علماء المساحة البحرية بدراسات للمياه الصالحة للملاحة، بما في ذلك المحيطات والأنهار والبحيرات. وقاموا بإعداد الرسوم البيانية والخرائط التي توضح شكل السواحل وعمق المياه ووضع القنوات والشُّعب الصخرية وأماكن المياه الضحلة والصخور ومسار التيارات المائية. وقام علماء المساحة البحرية أيضًا بدراسة المد والجزر والرياح.

معلش سامحيني لقيتلك بس المعلومات دي بالانجلش ، بس ان شاء الله أدورلك على نتايج بالعربي

survey in its strictest sense is the process of gathering information about navigable waters for the purposes of safe navigation of vessels. It strictly applies to survey of any navigable waters, including lakes and rivers, but it is most commonly applied to marine navigation. The term may be more broadly used for a wide variety of data gathering exercises for the purpose of describing the seafloor for a variety of purposes. The largest hydrographic community globally is involved in the description of offshore oilfields from their initial design phase through to regular inspections of the infrastructure of a mature sub sea oil infrastructure. This may be commonly referred to as Offshore Survey

Hydrography is collected under strict rules for evaluating and positioning the data so that it may be accurately charted. Data will include shore features of use to navigators as well as information about the waters and bottom. Traditionally conducted by vessels and with Echo sounding, surveys are increasingly conducted with the aid of aircraft and sophisticated electronic sensor systems in shallow waters. United States Navy SEALS and Seabee Underwater Construction Technicians(UCT) also have the ability to conduct hydrographic surveys. The SEAL/UCT operators are normally called upon before amphibious landings in order to survey the landing beaches.

Surveys are most commonly conducted by or under the supervision of national organizations with responsibility for chart making and distribution. Coordination of those organizations voluntarily joined with the goal of improving hydrography and safe navigation is conducted by the International Hydrographic Organization.
