These processed bathymetry grids were generated from single-beam sonar data collected in 2003-2007 as a part of ecological surveys carried out by the University of Bologna, Italy. The bathymetry data was acquired using a Lowrance HDS sonar operating at 200 kHz coupled with a WAAS-enabled D-GPS for navigation, and was processed by means of the kriging interpolation method using Surfer Golden Software.

Abstract
These processed bathymetry grids were generated from single-beam sonar data collected in 2003-2007 as a part of ecological surveys carried out by the University of Bologna, Italy. The bathymetry data was acquired using a Lowrance HDS sonar operating at 200 kHz coupled with a WAAS-enabled D-GPS for navigation, and was processed by means of the kriging interpolation method using Surfer Golden Software. In most cases, the XY grid spacing was set at 0.5 m, but, in some cases according to areal coverage of data, was set to finer or coarser spacings: 1 m for TC2, Term14, TM1, TM4; 2 m for P208; and, 0.1 m for TSO. Depth values were tide-corrected and referred to the Mean Lower Low Water (MLLW) based on astronomical tide prediction (calculated by WXTide32 software using harmonic data for the nearest available station, i.e. Chioggia or Malamocco). The grid projection is in WGS84 / UTM Zone 33N (EPSG:32633). These bathymetry grids are provided in ESRI ASCII grid format and correspond to the annotated GeoTIFF images in the related data set.
