Latest version published by Hellenic Center for Marine Research on May 28, 2020 Hellenic Center for Marine Research

This is a historical dataset that was published in 1939 by Ad. Steuer and concerns of the faunistic report on the Mollusca collected during the floristical and faunistical survey on the coasts near Alexandria mainly with the vessel “El Hoot”. This dataset covers the time span of 1/4/1933 to 18/11/1933 and contains occurrence data of Molluscs in the coasts of Alexandria, Egypt. For some species, the dataset contains individual counts, sex, life stage and body length. The digitization of this dataset was done by LifewatchGreece team.

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 145 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.

  • Event (core)
  • Occurrence

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.

Sampling Methods

This dataset is only a part from a large expedition that took place in the coasts near Alexandria. The samples were collected by A. Steuer. For bottom samples almost exclusively a dredge with 20x70 cm opening was used. A single catch was made in a depth of 20 m with a large otter trawl in the eastern part of the Bay of Abukir. For plankton samples, vertical hauls were made using medium sized nets with buckets of celluloids with gauze bottom. In general, the motor-launch of the Marine Laboratory "El Hoot" was used for dredging and a rowing boat in shallow water. All excursions were one-day trips. After the expedition, taxonomic identification of the samples was done by specialists. The results of this expedition were published in separate for each taxonomic group volumes. Thus, sampling methods were described in a preliminary report by A. Steuer. Taxonomic identification of mollusc species was made by J.R. Le B. Tomlin, G.H. Crawford and S. Jaeckel.

Study Extent This dataset is based on a faunistic report compiled from the expedition by the Fisheries Research Directorate in fishery grounds near Alexandria at 1933.
