Description
Free-living nematodes of 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. The nematodes (38–1000 m) 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). For each pseudoreplicate, 100 nematodes were randomly picked out using a fine pin under a stereomicroscope (Zeiss Discovery V20, magnification 40×), transferred from formalin to glycerol through a series of ethanol-glycerol solutions and finally mounted on permanent glass slides in anhydrous glycerin. Nematodes were identified under a microscope (100x magnification) at the genus level using dedicated pictorial and identification keys.
Data Records
The data in this sampling event 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 51 records.
2 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
In its Blue paper (COM2007/575 of October 10th 2007) the European Commission highlighted the need to implement an integrated maritime and marine policy in order to “enhance Europe's capacity to face the challenges of globalisation and competitiveness, climate change, degradation of the marine environment, maritime safety and security, and energy security and sustainability.” It stated further that such a policy “must be based on excellence in marine research, technology and innovation”. The aim of RITMARE is to implement what is suggested in the Blue Paper in terms of research and innovation, by means of a national programme of scientific and technological marine research. More specifically, RITMARE has been structured around the following three objectives: to support integrated policies for the safeguard of the environment (the health of the sea); to enable sustainable use of resources (the sea as a system of production); to implement a strategy of prevention and mitigation of natural impacts (the sea as a risk factor). In this framework, RITMARE represents a significant opportunity for the Italian marine scientific community to: Increase synergies between those Research Bodies and University Consortia that are involved in marine research, facilitating the emergence of excellence and promoting cooperation; Strengthen cooperation between the world of research and Italian Industry in two complementary directions: inducing the research community to respond to the needs of industry and encouraging the latter to contribute to a relaunch of the technologies available to marine researchers. This will enable the creation of a new generation of researchers, specifically by means of industry-research joint doctorates; Enhance Italian participation in European projects and initiatives, increasing the number of Italian scientists appointed as project coordinators and promoting participation in joint programmes (e.g. JPIs) where the resources made available by the participants are matched by contributions from the EU. The objective over the five years is to set up a system for maritime research that is more internally cohesive, better coordinated with the international scientific community and more in tune with Italy's economic and industrial players.

Method step description:
- 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. The nematodes (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). For each pseudoreplicate, 100 nematodes were randomly picked out using a fine pin under a stereomicroscope (Zeiss Discovery V20, magnification 40×), transferred from formalin to glycerol through a series of ethanol-glycerol solutions and finally mounted on permanent glass slides in anhydrous glycerin. Nematodes were identified under a microscope (100x magnification) at the genus level using dedicated pictorial and identification keys. All data are converted to by multiplying them by a conversion factor (1.66).
