Descrição
This is a historical dataset, published in 1940, regarding the marine algae of Alexandria. The survey was conducted by A. H. Nasr, Assistant Director of the Marine Biological Station in Ghardaqa, Egypt and it was facilitated by the Fuad I Institute of Hydrobiology and Fisheries in Alexandria, Egypt. The dataset contains occurrence data of the algae found in the wider marine region of Alexandria within the year 1933.

Métodos de Amostragem
The samplings were realised in one day trips with the use of the vessel "El hoot", a motor boat of 15 metres. In favourable weather conditions a rowing boat was used instead, in order to approach shallow waters and cliffs. The sampler for the benthic assemblages was a dredge with a 20*70 cm opening and in shallow waters the material was taken by diving. Collections on the shore were also made, whenever samples had been washed up onto it.
| Área de Estudo | This digitised historical dataset is part of the bigger floristical and faunistical qualitative survey "The fishery grounds near Alexandria" coordinated by Adolf Steuer. It concerns the area along the coasts of the city of Alexandria in Egypt during the year 1933. |
|---|---|
| Controle de Qualidade | Taxonomy checked using WoRMS (match taxa tool). |
