Here, scientists study a sediment core from a tropical saltmarsh to evaluate the impact of sea level rise on sediment accretion and carbon fluxes. Some geochemical indicators in a 210Pb dated sediment core showed clear signals of marine influence. This was reflected on increased accretion rates, from 0.3 ± 0.1 mm yr− 1 in ≈ 1941 to 2.9 ± 1.2 mm yr− 1 in 2012. [Source: Catena]
