(»Bredninger«) may be said perhaps, <>a an average, to be 3 — 4 fatlioms, aud 

 only qiiite exception:iJly, in a few holes, a depth of 11 — 13 fatlioms, is reaclied. 



— Though we can trace lide currents at many piaces of the Limfjord — wliich 

 most frequently, however, are ver_y irregular — they canuot be said to exercise 

 any perceptible infiueuce ou the height of the water, except at the very mouths, 

 and even here the difference between highwater and low-water is only a few 

 inches. — lu the main coiirse of the fjord, from the North Sea, east of Mors, 

 past Løgstør to the Cattegat, a distance of c. 92 miles, we find, however, 

 nearly always rather a considerable current in the water, running now east- 

 ward, now westward, most commonly, however, eastward. It seems as if this 

 cnrrent differs very much in the differeut years. It is said, for instance, in 

 some years to run, decidedly, much oftener eastward than westward; in other 

 years this difference is not so marked, though it must be said that there always 

 runs more water through the Limfjord eastward than westwai'd. I think it 

 even very improbable that any mass of water ever runs through the Limfjord 

 from the Cattegat to the North Sea, as the average saliuity of the year, in 

 1896, was 1,^ p. et. at Aalborg, 3,o p. et. at Oddesund, aud 3,3 p. et. on the 

 western shore of Jutland. 



The streng currents in the narrow sounds, in the main course of the 

 fjord, Thyborøn, Oddesund, Sallingsund, bj' Løgstør, etc, are weakened of 

 course, when they reach the large, remote expansious in the western part.*) 



— On account of the inconsiderable depth of the fjord there is generally no 

 difference in the temperature and salinity at the surface and at the bottom. 

 When we have seen, how each of the frequent storms can put the light 

 materials of the bottom in motion, so that the whole mass of water gets a 

 j'ellowish colour, we understand that there is, as a rule, but one layer of water 

 in the expansious of the Limfjord. In quiet weather the volumes of water 

 which come pouring into the fjord from the rivulets, may certainly make an ex- 

 ceptiou to the rule, but these exceptions are always very local and of very 

 short duration. — 



It will be understood, what an immense difference there is between a 

 fjord like this with a mass of water, which is frequently reuewed from bottom 



*) In the abovementioned article by Holt, thea uthor wants information of the speed 

 of the current in the Limfjord, espeeially in order to judge, whether it canhave any in- 

 fluence on seining, for instance by gathering the arms of the seine. I shall state, there- 

 fore, that in the very expansions, particularly in the large ones, the current is generally 

 not so strong that it has any perceptible influence on seining. His supposition, loc. cit., 

 p. 82, that the seinings I have mentioned are undertaken > under practically identical con- 

 ditions of tide, weather, temperature etc.« is therefore quite correct.
