5. Recce / TMSI team only
Random sampling to assess general biodiversity
With volunteers
Belt transects (50 m) as standard protocol for qualitative
biodiversity information
Quantitative data for specific sites and targeted biota to be
carried out in the future
Material needs to be preserved for:
accurate species identification
voucher (reference) material in RMBR
6. Mudflat survey
Sampling methodology
Two major components of faunal
diversity:
Infauna
Epifauna
Infaunal sampling using simple manual
excavation, 1 mm/2 mm sieves, yabby
pumps
Epifaunal sampling using seines/push
nets
Sampling for meiofauna (small benthic
invertebrates that are < 1 mm in
maximum dimension) using fine sieves
7. Part II of CMBS
Sampling of subtidal benthic fauna within Singapore Port limits
Volunteers are needed both onboard vessel and in the laboratory
for sorting and identification
10 nautical grids have been covered done since beginning of
surveys
Lab sorting sessions are held in TMSI (St John’s Island and NUS
campus) after surveys
No. of specimens collected 1912 (More sorting n counting to go)
No. of specimens identified to species 127
% of specimens identified to species 6.6%
No. of species collected and identified 54
