Meiofauna monitoring in the Mar Piccolo of Taranto (Ionian Sea, southern Italy), 2013-2014 in the framework of the Italian flagship project RITMARE. In June 2013 and April 2014, sampling was carried out at four sites by scuba divers who collected five virtually undisturbed sediment cores using polycarbonate sample tubes (12.7 cm I.D. with a sample area of 127 cm2). In laboratory, one sediment core was subsampled by means of 3 cut-off plastic syringes (2.7 cm I.D., surface area of 5.72 cm2, 0-10 cm top sediment) in order to obtain three pseudoreplicates for the meiofauna. Meiofaunal organisms (38–1000 µm) were extracted from sediment subsamples by sieving each pseudoreplicate and by centrifuging the material retained by a 38 μm mesh net with Ludox HS-40 (density of 1.15–1.18 g cm−3). All meiobenthic organisms were counted and taxonomically classified to the main groups under a stereomicroscope (Olympus SZX12; final magnification of 32-40x).Sampling Description

Replicates were sampled and analysed to take into account biological variability.Method steps
- Sampling was carried out at four sites by scuba divers who collected five virtually undisturbed sediment cores using KC Haps bottom corer with polycarbonate sample tubes (12.7 cm I.D. with a sample area of 127 cm2). In laboratory, one sediment core was subsampled by means of 3 cut-off plastic syringes (2.7 cm I.D., surface area of 5.72 cm2, 0-10 cm top sediment) in order to obtain three pseudoreplicates for the meiofauna. Meiofaunal organisms (38–1000 µm) were extracted from sediment subsamples by sieving each pseudoreplicate and by centrifuging the material retained by a 38 μm mesh net with Ludox HS-40 (density of 1.15–1.18 g cm−3). These pseudoreplicates were preserved in buffered 4% formaldehyde solution using prefiltered seawater and stained with Rose Bengal (0.5 g L-1). All meiobenthic organisms were counted and taxonomically classified to the main groups under a stereomicroscope (Olympus SZX12; final magnification of 32-40x). All data are converted to by multiplying them by a conversion factor (1.66).
