On October 25, 1994, the Portuguese Republic Vessel "S. Miguel", which was carrying a large amount of old military equipment, sank in the waters of the Portuguese continental EEZ, parallel to Lisbon. This sinking, which was attempted under controlled conditions under the Oslo Convention for the Prevention of Marine Pollution, was marred by an accident and the ship broke the sea surface before sinking. After this accident, an assessment was made of the environmental impact of the explosion and sinking of the ship. The objective was to verify a possible decrease in zooplankton biomass values in the surface layer of the water column (200 m) in the sinking area. The parameters that were considered capable of giving indications about the state of zooplankton populations were the abundance (biovolume) and the specific zooplankton diversity of the epi- (living in the 0 to 150 meters depth) and mesoplankton (living in the 150-meter depth) regions. 1000 meters deep).
