2. The Lim Fjord. The couditions are quite differeut here and greatly 

 favour the formation of dead weed. The movement of the waves carries the loose 

 Zostera from the coastal margins to deeper parts, and ou aceount of the very 

 small curreut, the dead weed may be deposited almost everywhere. The investi- 

 gatious also show in reality, that the dead weed is widely distributed in Nissum 

 Bredning, Venø Bugt, Kaas Bredning and Thisted Bredning (see the Chart Hg. 7). 

 At many piaces the dead weed is mixed with the Fvrcellaria vegetation, frequeutly 

 for example in the Nissum Bredning. 



3. Kattegat. Large masses of dead weed are found in the Læsø Chan- 

 nel as well as in the deep channel east of Læsø, as is shown on the Chart fig. 8. 

 On the other hånd, there is not much dead material in the large shallow plateau 

 of Aal))org Bay, as suitable deep piaces are wanting. 



More to the south where the depths in the Kattegat become more varied, 

 there are distinct chaunels and deep, calm fjords and the accumulations of dead 

 weed reappear here and there, e. g. in Baaring Vig and the bay west of Hindsholm. 



5. Little Belt. Large masses of dead weed are found north of Brandsø, 

 also all along the west and south coasts of the island of Funen, in depths of 

 8 fathoms and more. 



6. Great Belt and Langeland Belt. The eonditions here are similar 

 to those in the Little Belt. In the channels between Romsø and Sprogø, as well 

 as over a large tract south-east of Sprogø, large masses of dead weed are to be 

 found in 10 — 20 fathoms of water, likewise on both sides of Vresen and down 

 through the waters between Funen and Langeland. The current has also carried 

 cousiderable quantities of dead weed down into the deep channel between Aggersø 

 and Zealand. 



As regards the other waters, I have too little information to be able to 

 make any statements with confidence. It may however be mentioned, that south 

 of Glænø in the Smaaland Waters dead weed is found in 6 — 7 fathoms and most 

 probably the same is the case at many other piaces in the Smaaland AVaters. 

 Finally, some dead weed has beeu found in the Baltic south of Rødsand in 12 — 14 

 fathoms of water, and according to J. Reinke (1. c ) it seems to be fairly common 

 in the whole of the Western Baltic.
