Description
This dataset contains occurrence records of infralittoral molluscs from two infralittoral rocky shore sampling sites in northern Crete (Greece). Samples were collected for a monitoring project of infralittoral rocky shores in Crete, in the framework of the NaGISA project (Natural Geography in Shore Areas, http://www.coml.org/projects/natural-geography-shore-areas-nagisa). The two sampling sites are characterised by a continuous hard bottom habitat with dense algal coverage and a moderate wave exposure and are not impacted by detectable anthropogenic activity. At each site, five random replicate units were collected from each depth of 1m, 5m, 10m, 15m and 20m by placing a plexiglas frame (25x25 cm) on the substrate and scraping the framed area completely. The samples were then collected with an underwater suction device working with pressure from a diving bottle. Samples were washed through a 0.5 mm mesh sieve and fixed in 99% ethanol. In the laboratory, all samples were identified to the most precise taxonomic level possible, using the most recent literature for the phylum. The pollychaetes records are available as a separate dataset in the dataset "Polychaetes from two subtidal rocky shores of the North coast of Crete, collected for the NaGISA project 2007-2008" available at http://ipt.medobis.eu/resource?r=nagisa_species_2007_2008.
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 20 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.
Versions
The table below shows only published versions of the resource that are publicly accessible.

Project Data
The Natural Geography In Shore Areas (NaGISA) project was a collaborative effort aimed at inventorying and monitoring habitat specific biodiversity in the global near shore. The international character of the project and its target zone were reflected in the word nagisa, which is Japanese for the narrow coastal zone where the land meets the sea. NaGISA held a unique position in the Census of Marine Life as an ambassador project, linking the Census to local interests around the world. NaGISA's first aim was to draw up a global baseline of nearshore biodiversity and then to use its network to continue monitoring those same shores for the next 50 years.

Sampling Methods
At each site, five random replicate units were collected from each depth of 1m, 5m, 10m, 15m and 20m by placing a plexiglas frame (25x25 cm) on the substrate and scraping the framed area completely. The samples were then collected with an underwater suction device working with pressure from a diving bottle. Samples were washed through a 0.5 mm mesh sieve and fixed in 99% ethanol
Study Extent | The two sampling sites are characterised by a continuous hard bottom habitat with dense algal coverage and a moderate wave exposure and are not impacted by detectable anthropogenic activity. The sampling sites are 1. Alykes-Agia Pelagia- Heraklion-Crete-Greek EEZ and 2. Elounda- Agios Nikolaos-Crete-Greek EEZ subtidal rocky shores from 1-20m with photophilic algae Bounding Coordinates: 35.13, 35.46 / 24.93, 25.83 (min, max Latitude / min, max Longitude) |
---|---|
Quality Control | In the laboratory, all samples were identified to the most precise taxonomic level possible, using the most recent literature for the phylum. Then the names are mapped against WoRMS. |
