Egyptian plankton samples for revision as to its phytoplankton content. First samples are dated in 1933 owned by Prof. Steuer, while the other samples are from the Nile area and collected by Dr. Hans Amberg, in 1904. The samples that come from the large district of the Nile prove that the Melosira in Prof. Steuer's material represents a real phytoplankton component of Nile water and not merely a passive swimming organism.

This dataset includes species found in the demosponge Sarcotragus foetidus. The sponges were collected form two stations, in depths between 5 and 17 meters. The stations were located in Linaraki (Sithonia, Halkidiki, Greece) and in Milourgia (Kissonerga, Pafos, Cyprus). Sampling in Cyprus was conducted in January of 2003 and August of 2003 and 2007, in depths between 5 and 10 meters. Sampling in Greece was conducted in February and July of 2003, in depths between 14 and 17 meters.

This dataset is part of a national project on the consequences of the Navarino Oil spill, in 1994 at the Gialova Lagoon, Ionian Sea. The Cretan coasts were studied from May 1987, in order to assess the level of their environmental degradation due to touristic and other anthropogenic activities

The Zoology Laboratory of the University of Thessaloniki, has undertaken an investigation relating to the benthic fauna of the Evvoia Coast and Evvoia Gulf since 1970. In this study were described specific benthic species. Some of them were recorded for the first time among the marine fauna of our country.

The Mass Mortality Events database (hereafter MME-T-MEDNet) is a collaborative initiative involving more than 30 research institutions from 10 Mediterranean countries including EU and non-EU countries. This initiative aims to facilitate the access to information (published in scientific journals and gray literature or still unpublished) related to Mediterranean Mass Mortality Events (MMEs).
