Classic Winter Conditions on the Oregon Shelf

Here's the first section from Glider Bob's Oregon shelf mission. This is our fourth season of making Oregon shelf observations. During the winter, the surface layer is typically well-mixed down to 80 m, the pycnocline slopes downward toward the coast intersecting the bottom near the shelfbreak, and there is a small lense of fresh water very near shore from rain and run-off from small local rivers, and the currents are relatively strong and to the north. In this section, there is also a slight run up the shelf along the bottom of salty dense water, lead by some small scale variability that looks reminiscent of nonlinear internal waves a la the observations by Klymak and Moum (2004).
