This paper examines the response of submerged model sand
slopes to vibration and the beneficial effects of placing rock revetments
on the face of the slope to prevent flaw slides.
Pore water pressure response and deflection were used as a
criteria for stability in an attempt to relate stability with...
We examine the 0–100 Ma paleoceanographic record retained in pelagic clay from the South Pacific Gyre (SPG) by analyzing 47 major, trace, and rare earth elements in bulk sediment in 206 samples from seven sites drilled during Integrated Ocean Drilling Program Expedition 329. We use multivariate statistical analyses (Q-mode factor analysis...
Dating pelagic clay can be a challenge due to its slow sedimentation rate, post-depositional alteration, and lack of biogenic deposition. Co-based dating techniques have the potential to create age models in pelagic clay under the assumption that the flux of non-detrital Co to the seafloor is spatially and temporally constant,...

Soil acidification sometimes is necessary for optimum plant growth
west of the Cascade Mountain Range. Commercial producers of
blueberries, azaleas, rhododendrons, and other ornamentals may
need to reduce soil pH for optimum production.
Soil acidification is best performed prior to planting; it is much
more difficult in established plantings. No...
This publication is a technical and practical guide for soil acidification in commercial fields. It explains the soil chemistry involved, how to determine whether pH adjustment is feasible, and methods for acidifying soil. This guide is divided into five sections:
• Understanding soil pH
• The problem—iron chlorosis
• Causes...
