Abstract:
The dataset contains quality checked, post processed echo soundings as point data (not gridded). It represents the coastal bathymetry in September 2016 in front of "Bunker Hill" at the southern West coast of the island Sylt, in the German Bight of the North Sea. The "WaveDiss" field experiment was conducted from September 21. to October 2., 2016 at the Island Sylt in the North Sea. The goal of the experiment is to provide ground truth data for validation and development of radar remote sensing methods to study nearshore hydro- and morphodynamics (Link: https://www.hzg.de/institutes_platforms/coastal_research/operational_systems/radar_hydrograph/projectsy/index.php.en#tab-25).

Comment:
Single beam echo soundings acquired with an over the bow mounted transducer, RESON 600 operating at 210kHz. For accurate positioning a GNSS master antenna of Javad Gyro-4T, which received phase corrections (RTCM 3.0) from a shore based reference station, Javad GNSS (NAVSTAR GPS and GLONASS). This dataset was recorded as well as post processed using the hydrographic software Hypack®. Within the post processing the sound speed (CTD casts with a Sea&Sun CTD) and tide corrections (RTK tides) were included. For georeferencing of echo soundings all sensors offsets, heave, roll and pitch were applied, evident outliers removed, coordinate transformation from WGS84 to Universal Transverse Mercator (UTM) zone 32N was calculated and the vertical reference as mean sea level (German: Normal Null) on EGG97 with a fixed geoid separation of 40.17m applied. Last but not least the RTK tides were compared to gauge measurements of the station at Westerland and echo soundings profiles were double checked by a dedicated Cross Check Statistics module of Hypack.
