The current state and issues of standardization of hydrographic surveys performed for engineering purposes on inland water areas, coastal zone of the seas and continental shelf examined. There is a variety of existing regulatory documents based on outdated norms and rules of traditional analog hydrography issued more than forty years ago. There are a number of regulatory documents governing the survey of the bottom relief in order to ensure hydraulic construction, dredging, construction of structures on the continental shelf, as well as special surveys on the downstream of hydroelectric power

Abstract:

After Global Navigation Satellite Systems (GNSS) were first used in the field of hydrography in 1980, developments in hydrographic surveying accelerated. Survey precision in hydrography has been improved for both horizontal and vertical positioning and seafloor acoustic measurement by means of these new developments. Differential Global Positioning System (DGPS), Real Time Kinematic (RTK) and Network RTK (NRTK) techniques are the satellite-based positioning techniques that are commonly used in shallow water surveys and shoreline measurements.

Abstract:

A hydrographic survey is a standardized procedure for collecting data for the production of nautical charts and publications. It is a lengthy and costly procedure, so the survey is carried out depending on the capabilities of hydrographic organizations. It is known that relatively large parts of the world's oceans are very poorly covered by hydrographic surveys. To increase the amount of data collected, the International Hydrographic Organization (IHO) has introduced the concept of crowdsourced bathymetry (CSB).

Abstract:

In the 1830s and 1840s, the Hydrographic Office of the British Admiralty developed and oversaw one of the major state-run surveying projects of the nineteenth century. This involved a range of instruments whose circulation was increasingly regulated. Using extant museum collections and the correspondence of those involved, this article explores how such objects can be used to discuss both bureaucratic organization at a time of expanding government and the complex issues of sociability involved in hydrographic surveying. Surveying officers worked in a context in which the propriety of property

Abstract:

SynopsisThe Highland River Purification Board is carrying out a detailed study of the effect of Inverness sewage on the Beauly and Inverness Firths to ascertain the present degree of pollution and the best location for a new outfall. The survey comprises hydrographic work to identify the main currents in the Longman area, analysis of water and sewage quality and surveys of the littoral and sub-littoral fauna.

Abstract:

The lack of knowledge on the distribution and taxonomy of ichthyofauna from coastal Atlantic Rainforest of Santa Catarina state, Brazil, is noteworthy. This study presents a rapid but comprehensive survey of fish species from the coastal hydrographic regions of Santa Catarina. The samples were conducted in October 2012, in 19 sampling sites of five hydrographic regions, using sieves, seine nets, and throw nets. A total of 1,878 individuals belonging to 51 species distributed in 16 families are reported; four freshwater fish species represent distribution novelties for the region. The families

Abstract:

In recent years, interest in the oceanography of the subarctic ocean area has lead to increased activity in the Marginal Ice Zone (MIZ) in terms of bathymetric and hydrographic data collection with an associated increase in damage reports. The hazards of the MIZ include floating ice, topside icing, cold weather and heavy seas, each of which calls for special attention in design. The Oceanographer of the Navy's requirement for data from this region has led him to specify that the FY92 T-AGS Ocean be capable of operation in the MIZ. This paper describes the design process followed to meet this r

Abstract. During winter 2003 and 2004, zooplankton and hydrographic data were collected in the northern parts of the Norwegian Sea (68–72° N, 8–17° E) west of the Norwegian shelf break at depths down to 1800 m. The results cover both inter and intra annual changes of hydrography and distribution of Calanus spp. For the whole survey area, average seawater temperature down to 1000 m was higher in 2004 than in the same period in 2003. For the upper 500 m the difference was ca. 1°C. Calanus finmarchicus dominated at ca. 75% of the total copepod abundance. Typical abundance of C. finmarchicus in th
