Description
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).

Sampling Methods
The epizooplanktonic material was sampled in oblique trawls up to a depth of 200 m using a Bongo 60 net (circular double-mouth net 60 cm in diameter and fitted with two mesh bags of 335 and 505 m aperture). The volume of water sampled in each haul was calculated using the readings of flowmeters attached to each net's mouth. Mesozooplankton was collected using a 10 m2 mouth area Isaacs-Kidd Midwater Raul (IKMT) net with a 505 m mesh bag. The hauls took around 30 minutes to complete at the desired depth.
| Study Extent | The epizooplankton was collected in 12 sampling stations, which were distributed as follows: Three stations along the Portuguese coast, one at the sinking site, four surrounding the sinking site and ten miles apart, two at the Josephine bank and one at the Bank Gorringe. |

Method step description:
- All zooplanktonic material collected was kept in 4 percent neutral formalin, with the exception of a tiny portion of the material collected with IKMT that was frozen for examination of the concentration of heavy metals and PCBs. The biovolume of plankton samples was computed in the lab using the volume of water displaced by the organic material after large organisms (> 1 cm in epizooplankton and > 2.5 cm in mesozooplankton) were removed, and its abundance was calculated per 100 m3 of filtered water. Using a magnifying glass and a binocular microscope, species identification and enumeration were carried out in a counting chamber.
