Delta Heritage & Archaeology has been asked to write the Maritime Cultural Heritage page for the ESIA for a dredging and especially the disposal area (ca. 1 million cubic square meter) near Cartagena, Columbia. Significant adverse effects from indirect impacts to underwater cultural heritage, if present, may occur during activities in and/or in the vincinity of the the disposal area, such as:

  • propeller wash and dynamic positioning (damage to or disturbance of archaeological material exposed or undermined by propeller wash);
  • anchoring and jack-up barges (physical damage to archaeological material and deformation of the surrounding seabed deposits, unexpected retrieval of archaeological material caught on anchors, etc.);
  • dredged material disposal (displacement of archaeological material present within disposed materials, loss of context)
