Latest version published by Hellenic Center for Marine Research on Apr 16, 2020 Hellenic Center for Marine Research

This is a historical dataset that was published in 1937 by Th. Mortensen and Ad. Steuer and concerns of the faunistic report on the Echinoderma collected during the floristical and faunistical survey of Adolf Steuer on the coasts near Alexandria mainly with the vessel “El Hoot”. In this historical paper, there are no information about exact sampling temporal coverage. This dataset contains occurrence data of Echinoderma in the coasts of Alexandria, Egypt. It also contains information about individual counts, sex and lifestage. 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 81 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.

  • 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 faunistical 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. 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 only described in a preliminary report by A. Steuer. Echinoderma species that collected in this expedition were identified by Th. Mortensen.

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