Mean (± SE) dry bulk density (g cm−3), organic matter (%), organic carbon (% Corg and kg Corg m−2 in 1 m-thick soils), δ13C (‰), and sediment grain-sizes < 0.016 mm, > 0.0.016 < 0.125 mm and > 0.5 mm (%) in seagrass soils from Alta Guajira, Cartagena Bay, Media Guajira and San Andrés in the Colombian Caribbean. Results of GLM tests to assess differences are denoted: different letters (a, b, c) indicate significant differences (P < 0.05).
