Velocity time series are used to study cross-shelf circulation on the northern California shelf and to examine classical ideas of locally wind-forced cross-shelf circulation. A simple linear two-dimensional model of cross-shelf transport is compared to estimates of cross-shelf transport in the near surface, interior, and near bottom. In winter, when...
Farmers, conservationists, and other land managers need reliable methods to assess soil quality so they can make management decisions
that maintain long-term soil productivity. A group of Oregon farmers has identified 10 soil quality indicators for the Willamette Valley that
can assess the impact of soil management. These indicators are...
