“…14 C in DIC of the Northern Indian Ocean Figure 5) [Bhushan et al, 2000;Dutta et al, 2007]. The reduction in the surface D 14 C values can be partly attributed to the lowering of the atmospheric D 14 C from $300‰ during 1978 [Nydal and Lövseth, 1996;Chakraborty et al, 2008] to $90‰ in late 1990s [Bhushan et al, 1997;Dutta et al, 2006], and transfer of 14 C-enriched waters from the surface to the deeper layers through vertical mixing.…”

“…The first measurements of 14 C in the water column of the Arabian Sea and the Bay of Bengal were done during 1977 and 1978, as a part of the international GEOSECS program [Stuiver and Östlund, 1983]. Based on reoccupation of three Arabian Sea GEOSECS stations, Bhushan et al [2000] described temporal changes in radiocarbon distribution about two decades after GEOSECS.…”

“…Earlier studies on the air-sea exchange of CO 2 in the northern Indian Ocean also highlighted that the northwestern part of the Bay can act as a sink for atmospheric CO 2 Bhushan et al, 2000Bhushan et al, , 2003Dutta and Bhushan, 2012). In addition, several other factors such as turbidity, intense cloud cover and narrow shelf region of the Bay makes this region low in productivity (Qasim, 1977;SenGupta et al, 1977;Radhakrishna et al, 1978;Gauns et al, 2005).…”
