The ORNL DAAC recently released the following Delta-X dataset by Christensen, A.L., et al. (2021):
This dataset provides river discharge measurements collected at selected locations in the Atchafalaya and Terrebonne Basins within the Mississippi River Delta floodplain in coastal Louisiana, USA. The measurements were made during the Delta-X Spring campaign from 2021-03-26 to 2021-04-11. Channel surveys were conducted with a Teledyne RiverPro acoustic doppler current profiler (ADCP) on selected wide channels (>100 m wide) and a few selected narrow channels (approximately 10 m wide).
Delta-X is a 5-year NASA Earth Ventures Suborbital-3 mission to study the Mississippi River Delta in the United States, which is growing and sinking in different areas. River deltas and their wetlands are drowning as a result of sea level rise and reduced sediment inputs. The Delta-X mission will determine which parts will survive and continue to grow, and which parts will be lost. Delta-X begins with airborne and in situ data acquisition and carries through data analysis, model integration, and validation to predict the extent and spatial patterns of future deltaic land loss or gain.
Additional data from the Delta-X project can be found on the Delta-X Project page.
