Their areas amount to 15 and 10-10 km, respectively (Hay and Southam 1977). However for the two shelf types well-constrained estimates of how much carbonate is produced are missing. In the context of shelves it may be important to separate two other specific bioherms which could have a great potential in shallow-water carbonate production. These are sedimentaiy carbonates exclusively built up by the calcareous green algae Halimeda in tropical latitudes (e.g. Roberts and Macintyre 1988) and extensive biotic cold-water carbonate reefs or banks as described above for mid to high latitudes. For Halimeda bioherms total carbonate production and accumulation is about 1.510 mol yr (Table 9.1) while the estimates for open shelves given by Wollast (1994) and Milliman and Droxler (1996) do not differentiate a...
