Description
Microphytobenthos collected near mussel farm activities in the Gulf of Trieste - North Adriatic Sea in the framework of SosteMiTS Project financed by Friuli Venezia Giulia Region. Data collected in 2008-2009.
Data Records
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 11,040 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Project Data
Research study on the impact of mussel farming on the pelagic and benthic ecosystem in the Gulf of Trieste, North Adriatic Sea.

| Identifier | SDN:EDMERP::11808 |
| Funding | Friuli Venezia Giulia Regional Administration |
| Study Area Description | Gulf of Trieste, North Adriatic Sea |
| Design Description | Two sampling experiments were carried out in areas close to operative and dismissed offshore mussel farms to evaluate the microphytobenthic community in different environmental conditions. |
The personnel involved in the project:
Sampling Methods
At each point, scuba divers collected 3 virtually undisturbed sediment cores using polycarbonate sample tubes (12.7 cm I.D) with a sample area of 127 cm^2. Subsamples of the upper 1.5 cm were taken for microphytobenthos analysis.
| Study Extent | The study was carried out in September 2008 and March 2009 in a coastal area of the Gulf of Trieste. Four sites, characterised by similar biogeochemical and geomorphological features, were chosen because subjected to a different degree of potential impact due to mussel farming: a twenty-year farm (45 45.140 N, 13 38.590 E); a four-year farm (45 45.060 N, 13 38.660 E); a farm disused for more than 12 years (45 44.930 N, 13 39.090 E) and a control site located 250 m ca. away from the farms (45 44.820 N, 13 39.060 E). In each site, sediment samples were collected at 5 stations (A, B, C, D, and E) located along the direction of the dominant current flux. The distance among stations was 6 m ca. At each station, 3 points (e.g. A1, A2, and A3), 1.5 m away from each other, were sampled. |

Method step description:
- For the microphytobenthic analyses, aliquots of 2 cm^3 of homogenised sediment were withdrawn using a syringe and directly fixed with 10 ml of formaldehyde (4% final concentration) buffered solution CaMg(CO3)2, in pre-filtered bottom seawater (0.2 ml filters). After manual stirring, 20 microlitter aliquots of the sediment suspension were drawn off from the slurries and placed in a counting chamber. Only cells containing pigments and not empty frustules were counted under a Leitz inverted light microscope (Leica Microsystems AG) using a 32X objective (320X final magnification) (Utermöhl, 1958).
