Journal ArticleDOI
Fluvial responses to climate and sea‐level change: a review and look forward
TL;DR: In this paper, a review of the development of ideas in the fields of geomorphology/Quaternary geology vs. sedimentary geologies is provided, and key processes that operate to produce alluvial stratigraphic records over time-scales of 103−106 years.
Journal ArticleDOI
Mississippi Delta subsidence primarily caused by compaction of Holocene strata
Torbjörn E. Törnqvist,Davin J. Wallace,Davin J. Wallace,Joep E.A. Storms,Joep E.A. Storms,Jakob Wallinga,Jakob Wallinga,Remke L. Van Dam,Remke L. Van Dam,Martijn Blaauw,Martijn Blaauw,Mayke S. Derksen,Cornelis J. W. Klerks,Camiel Meijneken,Camiel Meijneken,Els M. A. Snijders +15 more
TL;DR: In this article, a series of radiocarbon-dated sediment cores from the Mississippi Delta were used to analyse late Holocene deposits and assess compaction rates, and they found that millennial-scale compaction rate primarily associated with peat can reach 5mm per year, values that exceed recent model predictions.
Journal ArticleDOI
A Revised Chronology for Mississippi River Subdeltas
Torbjörn E. Törnqvist,Tristram R. Kidder,Whitney J. Autin,Klaas van der Borg,Arie F M de Jong,Cornelis J. W. Klerks,Els M. A. Snijders,Joep E.A. Storms,Remke L. Van Dam,Michael C. Wiemann +9 more
TL;DR: In this paper, radiocarbon measurements by accelerator mass spectrometry relating to three of the four late Holocene Mississippi River subdeltas yielded consistent results and were found to differ by up to 2000 carbon-14 years from previously inferred ages.
Journal ArticleDOI
Vulnerability of Louisiana's coastal wetlands to present-day rates of relative sea-level rise
TL;DR: Comparison of vertical accretion rates with RSLR rates at the land surface shows that 65% of wetlands in the Mississippi Delta may keep pace with R SLR, whereas 58% of the sites in the Chenier Plain do not, rendering much of this area highly vulnerable to RLSR.
Journal ArticleDOI
Global-scale human impact on delta morphology has led to net land area gain
Jaap H. Nienhuis,Andrew D. Ashton,Douglas A. Edmonds,A.J.F. Hoitink,Albert J. Kettner,Joel C. Rowland,Torbjörn E. Törnqvist +6 more
TL;DR: This model shows that present-day delta morphology varies across a continuum between wave, tide, and river dominance, but that most large deltas are tide- and river-dominated, which means that recent land gains are unlikely to be sustained throughout the twenty-first century.
