Two training workshops on sampling and analysing ballast water were organized in Gebze, Turkey (2-4 June), and Duluth, USA (19-21 October). Attending the workshops were Port State Control officers and marine biologists representing the Lead Partnering Countries (LPCs) of the GEF-UNDP-IMO GloBallast Partnerships Programme (GloBallast). The training focused on shipboard sampling followed by practical laboratory analysis of the sampled ballast water. It aims to equip participants with the skills to replicate the training at a national level.
