TAPPI Journal, 2017 Linerboard produced from old corrugated containers (OCC) shows lower strength properties in comparison with linerboard produced from virgin fibers. This study determined the influence of surface treatment with polyvinyl alcohol (PVOH), ethylene vinyl alcohol (EVOH) (as synthesized biodegradable polymers), chitosan, and anionic starch (as biobased and ...

Geochemistry, Geophysics, Geosystems, Volume 21, Issue 9, September 2020., 2020 Abstract The Trans‐Atlantic Geotraverse (TAG) hydrothermal field on the Mid‐Atlantic Ridge is one of the best‐studied hydrothermal systems to date. However, high‐resolution bathymetric data obtained in 2016 by an autonomous underwater vehicle (AUV) reveal new information about the distribution of active and inactive hydrothermal deposits, and their ...

Wide‐Angle Seismic Imaging of Two Modes of Crustal Accretion in Mature Atlantic Ocean Crust
Journal of Geophysical Research: Solid Earth, Volume 125, Issue 6, June 2020., 2020 Abstract We present a high‐resolution 2‐D P‐wave velocity model from a 225‐km‐long active seismic profile, collected over ~60–75 Ma central Atlantic crust. The profile crosses five ridge segments separated by a transform and three nontransform offsets. All ridge discontinuities share similar primary characteristics, independent of the offset.

CAYSEIS - magma-starved oceanic crustal accretion and transform margin formation in the Cayman Trough revealed by seismic and seismological data - Cruise No. M115, April 1 - April 28, 2015 - Kingston (Jamaica) - Pointe-à-Pitre (Guadeloupe) [PDF]
, 2016 About 57% of the Earth’s outer surface is oceanic crust and new ocean floor is continuously created along the 55,000-60,000 km long mid-ocean ridge (MOR) system. About 25% of MORs spread at an ultra-slow spreading rate of < 20 mm/yr.
