3. mynd. Vífilsstaðavatn. Sérhvert tölusett
strandsvæði er 200 m langt. (a) Botngerð. (b)
Tegundir: Magn/dreifing. Þéttleiki mosadýra
var metinn með eftirfarandi hætti: (1) Lítill/á
einstöku stað; (2) talsverður/ósamfelld
dreifing; (3) mikill/nokkuð samfelld dreifing.
– Lake Vífilsstaðavatn. Each numbered area is
200 m. (a) Bottom topography: black square =
clay/mud; dotted square = gravel; triangle =
small stones (<20−30 cm in diameter); circle
= larger stones (>30 cm); white square = sand.
(b) Bryozoan species: Density/distribution.
The density was evaluated as: (1) Low/
occasional findings; (2) Considerable/
discontinuous; (3) High/fairly continuous.
4. mynd. Norðurhluti Hafravatns. Sérhvert
tölusett strandsvæði er 200 m langt. (a) Botn-
gerð. (b) Tegundir: Magn/dreifing. Þéttleiki
mosadýra var metinn með eftirfarandi hætti:
(1) Lítill/á einstöku stað; (2) talsverður/ósam-
felld dreifing; (3) mikill/nokkuð samfelld
dreifing. – Northern part of Lake Hafravatn.
Each numbered area is 200 m. (a) Bottom
topography: black square = clay/mud; dotted
square = gravel; triangle = small stones (<20-
30 cm in diameter); circle = larger stones

distribution. The density was evaluated as:
(1) Low/occasional findings; (2) Consider-
able/discontinuous; (3) High/fairly continu-
ous.
5. mynd. Suðurhluti Hafravatns. Sérhvert
tölusett strandsvæði er 200 m langt. (a) Botn-
