Sediments
Table 5.1.
Particle size composition and percentage organic carbon and nitrogen in surface sediments
collected from Small Bay (SB), Big Bay (BB), Langebaan Lagoon (LL), Salamander Bay (S) and
Donkergat (D) in 2011. (Particle size and TOC analysed by Scientific Services, TON analysed by
CSIR). *The loss on ignition method was used to estimate TOC. These are not comparable to
previous years where a CHN analyzer was used.
