Fresh seaweed as sampled from the shoreline.
Wilting or natural drying was effected by laying samples out on
the perforated table. Samples were turned after a day and left to
wilt for a further 24 h and then frozen (20 C).
Washed seaweed was rinsed with water to remove any sand
and other impurities collected with the seaweed when removed
from the beach.
Dried seaweed involved laying the seaweed on top of wood pallets
with a gas furnace placed underneath burning constantly at
a temperature of 80 C.
