Posted: Mon May 05, 2025 2:34 pm America/New_York
ORNL DAAC recently released a new Delta-X dataset by Twilley, R. et al (2025):
Delta-X: Feldspar Sediment Accretion Measurements, MRD, LA, USA, 2019-2023, Version 4
This dataset provides elevation, hydrogeomorphic zone classification, soil carbon content, bulk density, organic matter content, and sediment accretion measurements collected at feldspar stations established near Louisiana's Coastwide Reference Monitoring Systems (CRMS) sites and on Mike Island in Wax Lake Delta (WLD).
