INFOMAR Seabed Sediment Classification

Geological Survey Ireland

Timpeallacht

This map shows the distribution of seabed substrate classes within Irish waters. High resolution grids of MBES bathymetry and backscatter data have been interpreted into 5 substrate classes: Rock, Coarse sediment, Mixed sediment, Sand and Mud to muddy Sand classes. Backscatter is

INFOMAR Shipwrecks

Geological Survey Ireland

Timpeallacht

This dataset shows the point locations of shipwrecks in Irish Waters surveyed by INSS and INFOMAR national seabed mapping projects. Over 480 surveyed shipwrecks have been recorded in the INFOMAR shipwreck inventory. The database accurately records the location of shipwrecks (know

INFOMAR Seabed Survey Trackline

Geological Survey Ireland

Timpeallacht

Survey tracklines delineate the line along which the vessel travelled as it was surveying. The vessel collects multibeam echosounder data (MBES) by emitting a fan of soundwaves and recording the reflected signal. The area of seabed ensonified is known as the footprint and the are

INFOMAR Seabed Survey Coverage

Geological Survey Ireland

Timpeallacht

This dataset shows the area of seabed mapped by both the INFOMAR and Irish National Seabed Survey projects to date. Each survey leg is represented by a unique polygon whose title is coded using the initials of the vessel that did the survey, the year the survey was completed and
