Can seaweed be a potential sink of carbon?
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 8
Abstract
We estimated stored carbon in three dominant seaweed species Enteromorpha intestinalis, Ulva lactuca and Catenella repens in three different seasons (premonsoon, monsoon and postmonsoon) from four sampling stations in the deltaic ecosystem of Indian Sundarbans (21°40' N to 22°40'N and 88°03'E to 89°07'E) during 2015. The average stored carbon content varied from 921.05 g m-2 (during monsoon) to 1163.02 g m-2 (during premonsoon) in E. intestinalis. In U. lactuca, the stored carbon ranged from 26.10 g m-2 (during postmonsoon) to 250.50 g m-2 (during premonsoon). In case of C. repens, the range of stored carbon is 9.11 g m-2 (during postmonsoon) to 76.89 g m-2 (during premonsoon). Amongst selected seaweed species, E. intestinalis showed uniformity in biomass between sectors (pcal = 1.59 < pcrit = 18.51) and seasons (pcal = 2.03 < pcrit = 4.14), which implies tolerance of the species to variable salinity and also potential of the species in the vertical of carbon sequestration.
