FIGURE 10.— The average number of cod larvae/m 2 surface on sections 1-8 and stations X and IX in the Austnesfjord, April-May 1980 



and 1981. 



Sections were also made at four locations in the 

 open water off the Lofoten islands. On three of these 

 sections (Eggum, Myrland, and Fuglehuk), patches 

 with high particle concentrations (>50/l) were ob- 

 served about 1 1 km (8 n mi) off shore. All sections had 

 low particle concentrations (10-30/1) in the surround- 

 ing water masses (Figs. 13-15). The similarity of the 

 positions of these three patches suggests that they 

 are components of the same water mass with higher 



particle concentrations than the surrounding water 

 masses. On the Skiva section (Fig. 16A-D) the parti- 

 cle distribution patterns were more complicated. 

 The section was surveyed during daytime and two 

 patches were observed, one at about 5-10 m (>100 

 particles/1) and another 20-25 m (>50 particles/1). 

 Particle concentration decreased further offshore. 

 The same section was surveyed at night (Fig. 16C), 

 and two surface patches were found.
