MARINE

Hydrographic surveys are the science of measurement and description of features that affect maritime navigation, marine construction, dredging, offshore oil exploration / offshore oil drilling and related activities. Strong emphasis is placed on soundings, coastlines, tides, currents, seabed and submerged barriers associated with previously related activities. The term hydrography is used for synonyms to describe marine cartography, which in the final stages of the hydrographic process uses raw data collected through a hydrographic survey into information that can be used by end users.

BENEFITS

Broadly speaking, hydrographic surveys are divided into 3 types namely oceanographic surveys, coastline surveys and bathymetry surveys. The first time we did was an oceanographic survey, which were measurements of currents, physical properties of seawater (salinity, PH, pressure, sound velocity), tidal data and seawater sediments. These data are needed to correct depth data in the bathymetry survey because the data obtained in bathymetry is still raw, affected by the nature of sea water.

CHALLENGES

Bathymetry mapping becomes important and fundamental for managing coastal areas. This certainly provides prospects as well as challenges for development, especially in the coastal areas and the marine sector.

SOLUTIONS

Technological developments in the world of surveying help to survey batrimetry as well. Which used to only use traditional methods, now there are many batrimetric surveying tools in circulation, such as the singlebeam echosounder, multibeam echosounder and side scan sonar.
