Inter-source interferometry of seismic body waves: Required conditions and examples
P. Saengduean, Morgan P. Moschetti, R. Snieder
2021, Pure and Applied Geophysics (178) 3441-3460
Seismic interferometry is widely applied to retrieve wavefields propagating between receivers. Another version of seismic interferometry, called inter-source interferometry, uses the principles of seismic reciprocity and expands interferometric applications to retrieve waves that propagate between two seismic sources. Previous studies of inter-source interferometry usually involve surface-wave...

Belowground productivity varies by assessment technique, vegetation type, and nutrient availability in tidal freshwater forested wetlands transitioning to marsh
Andrew From, Ken Krauss, Gregory E. Noe, N. Cormier, Camille Stagg, Rebecca Moss, Julie L. Whitbeck
2021, PLoS ONE (16)
Wetlands along upper estuaries are characterized by dynamic transitions between forested and herbaceous communities (marsh) as salinity, hydroperiod, and nutrients change. The importance of belowground net primary productivity (BNPP) associated with fine and coarse root growth also changes but remains the dominant component of overall productivity in these important blue...

Alan Condron, Jenna C. Hill
2021, Nature Communications (12)
High resolution seafloor mapping shows extraordinary evidence that massive (>300 m thick) icebergs once drifted >5,000 km south along the eastern United States, with >700 iceberg scours now identified south of Cape Hatteras. Here we report on sediment cores collected from several buried scours that show multiple plow marks align with Heinrich...

Laura A. Stern, S. Constable, Ryan Lu, Wyatt L. Du Frane, J. Murray Roberts
2021, Geophysical Research Letters (48)
CO2 and CH4 clathrate hydrates are of keen interest for energy and carbon cycle considerations. While both typically form on Earth as cubic structure I (sI), we find that pure CO2 hydrate exhibits over an order of magnitude higher electrical conductivity (σ) than pure CH4 hydrate at geologically relevant temperatures.

Introduced mangroves along the coast of Moloka‘i, Hawai‘i may represent novel habitats for megafaunal communities
Bryan A. Nakahara, Amanda Demopoulos, Yoshimi M. Rii, Rosanna A. Alegado, Kauaoa Fraiola, Craig R. Smith
2021, Pacific Science (75) 205-223
Mangrove forests are prevalent along tropical/subtropical coastlines and provide valuable ecosystem services including coastline stabilization, storm impact reduction, and enhanced coastal productivity. However, mangroves were absent from the Hawaiian Islands and their introduction to Moloka‘i in 1902 has provided an opportunity to examine their unique influence on coastal landscapes....
