取樣方法
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.
| 研究範圍 | 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. |
