Summary

The author discusses the questions whether Cheops ship no. 1 had or had not bilge edges and whether the central part of the bottom was flat, as her reconstruction shows, or was rounded. Furthermore the paper deals with the alledged »keel« and the asserted watertightness of the hull.

Summary

The paper deals with waterborne transport of big animals in the Near East and North Africa. The shipment of horses, cattle, deer, camels and elephants is attested already in the 3rd and 2nd millennium. Besides archaeological and written sources bones found in wrecks and land excavations bear evidence. Furthermore the author evaluates reports of modern travellers and ethnological studies.

Summary

In the 1998 campaign at Histria (Rumania) the so-called »Chaussée«, identified in the 1996 campaign, was investigated by sonar and divers, and mapped. This manmade concentration of stones turned out to consist of two lines likely to have formed Archaic walls Northeast of Acropolis Hill. In a shallow bay of Sinoe Lagoon widely overgrown by reed, the sonar identified straight moats which seem to form part of Hellenistic, or Roman fortifications around the »Harbour Gully« West of Acropolis Hill, identified in 1996.

Summary

Continuing his article on settlements in Polish lakes ( SKYLLIS 1, 1998 no. 2, p. 24-36) the author surveys the underwater archaeological work done on bridges and bridge-like constructions built in early historic and medieval times. The survey starts with the earliest findings made during drainage works on wetlands late in the 19th century and ends in the present days.

Summary

On July 19th, 1997 a DEGUWA team tested the underwater communication system »Buddy Phone« by the company JWL-Aqualung.
This system is an underwater communication system which is realized by ultrasonic. The modulation type is a single-sideband modulation.
For the test we had two Buddy Phone systems with hearing and speaking modules and one wholeface mask, one half-face mask and one base station.
The base station by which the diver can contact the surface is designed to be used ashore as well as on board.
All systems are normally in the hearing mode, only when you push the microphone key and hold it, the system switches to the speaking mode.
The system turned out to be useful during activities like searching, surveying and measuring of fi nds or reporting a fi rst-glance impression of them. However, the system is only of limited applicability, if the diver has to work with both hands, since when speaking he must press the speaking key continuously in order to be able to communicate.

Summary

A »Schiffsarchäologisches Seminar« has been organized at the University of Rostock every summer since 1996. The seminar`s priority aim is to impart knowledge in the field of maritime archaeology and fundamental principles of prospecting wrecked ships. The classes are held in the form of block seminars within 9 days. Thirty lessons are scheduled for the theoretical part and about the same number for the practical training. Students, but also interested amateurs or divers are potential participants in this seminar. There are intentions to extend this seminar to a regular education of maritime archaeologists.
