Description

Three seasonal sampling campaigns (winter, summer before touristic period, summer after touristic period) were implemented during 2012 in three Mediterranean touristic ports: Cagliari (Sardinia, Italy), Heraklion (Crete, Greece) and El Kantaoui (Tunisia). Three to five stations were sampled per port, which were part of different port sectors (leisure, fishing, passenger, cargo, shipyard). Three water and three sediment replicate samples were collected per station for analysis of nutrients, pigments and hydrocarbons. One replicate was analysed for physical parameters, heavy metals and granulometry. Five sediment replicates were collected for analysis of benthic biodiversity. Benthic organisms were sorted to the main taxonomic groups (e.g. .Annelida, Mollusca, Arthropoda, Echinodermata) and identified to species level.

Sampling Description

Study Extent

Ports of Cagliari-Sardinia, Heraklion-Crete, El Kantaoui-Tunisia

Sampling

Physical properties of water samples (water temperature, salinity, oxygen, pH) were measured on board with a 3420 WTW multi-meter. Turbidity was measured using a Secchi disk. Redox potential of sediment samples was measured with a SenTix ORP 900 WTW electrode. Sediment temperature was measured using a digital sediment thermometer. Water samples (5L) were collected using plastic containers from the sea surface and analysed for nutrients, pigments, hydrocarbons and heavy metals. Sediment samples were collected using a custom-made hand-operated box corer (13.5 x 13.5 x 16 cm) equipped with a modular expandable handle. For benthos box corer samples were sieved using a 0.5 mm sieve and then fixed and preserved in 5% formaldehyde buffered with seawater. For nutrients, pigments, hydrocarbons, heavy metals and granulometry sediment subsamples were collected using small plastic cores (diameter 4.4 cm).

Method steps

1)Five replicates per station for benthos. 2)Three replicates per station for water and sediment samples: nutrients, pigments, hydrocarbons. 3)One replicate per station for water and sediment samples: physical parameters, heavy metals, granulometry. 4)Water samples were collected from the seawater surface (depth 0-1 m).

Geographic Coverages

Cagliari: 5 stations (C1,C2,C3,C4,C5). Heraklion: 4 stations(H1,H3,H4,H5). El Kantaoui: 3 stations(E1,E2,E3). The values given below are maximum station depth. At the same time, this is sampling depth for all sediment samples and benthos. C1 = 7.8m, C2 = 4.5m, C3 = 8.3m, C4 = 13.5m, C5 = 11.4m. H1 = 3.7m, H3 = 19.5m, H4 = 10.5m, H5 = 19.0m. E1 = 2.5m, E2 = 4.0m, E3 = 3.2m.
