Xiaofei’s new paper entitled ‘ Provenance of Aerosol Black Carbon over Northeast Indian Ocean and South China Sea and Implications for Oceanic BC Cycling‘ has been accepted for publication in ES&T; and was chosen as a supplementary cover story of the issue. Congratulations!

Image chosen for a supplementary cover story of the ES&T issue. The little Asian elephant was added as an element to represent the South and Southeast Asia, where the studied area was.

Figure 3. Dual-carbon isotope signatures (δ¹³C_BC-Δ¹⁴C_BC) of aerosol black carbon over the South China Sea (SCS) and the northeast Indian Ocean (NEIO).

Figure 4. Source fractions (pie chart) and air mass back trajectories (colored lines) of aerosol black carbon (BC) in the dual-carbon isotope province of “SCS close to Chinese Mainland” (gray), “Open SCS” (green), “NEIO close to Southeast Asia” (blue), “Open NEIO” (light purple), “Malacca Strait” (pink) and “Sunda Strait” (orange). Air mass back trajectories in an isotope province share the same color. (SCS: the South China Sea; NEIO: the northeast Indian Ocean)
