Photograph of moonlight on the Pacific Ocean in Newport, Oregon, ca.1900/1950. The moon leaks moonlight out over the ocean from behind the clouds. The silhouette of a bush is visible in the foreground to the right. Near the water's edge to the left of the bush, the silhouette of a person can also be seen.

A seven level primitive equation equatorial ocean model with temperature and salinity is integrated over a 30 year period to a quasi-steady state. Placement of four of the seven levels of the model in the first 100 meters gives sufficient vertical resolution to resolve most major features of equatorial oceans. The model equivalents of the South Equatorial Current, the Cromwell Current, vertical upwelling in the equatorial area, Ekman divergence of mass toward each pole, and a thermocline were all simulated. A major conclusion was salinity probably has little effect on the general circulation patterns in the equatorial region. Additionally, the use of a vertical eddy diffusion coefficient for momentum that is dependent upon vertical stability, vertical current shear, and depth will probably be required to accurately model the vertical structure of the currents. http://archive.org/details/anoceforecasting1094516273 Lieutenant, United States Navy Approved for public release; distribution is unlimited.

Photograph of a view of Tillamook Head, near Seaside, Oregon, [s.d.]. Waves roll into whitecaps and crests while the silhouette of a large island cliff is visible in the left distance, shrouded by mist. The sun hangs in the sky to the right.

Photograph of a view of the Pacific shoreline showing Roosevelt Highway in the left distance, [s.d.]. A long wave can be seen across center moving towards the sandy shore in the foreground. A few rocks are visible in the extreme foreground, while a boulder is visible at left on shore. Utility poles can be seen alongside a road which borders the coastline in the left background. A steep rock incline with foliage on top of it can be seen just behind the road. The ocean is visible continuing into the background.

Photograph of a man looking down at a small schooner from the bluff above, [s.d.]. A man wearing light-colored pants and a long-sleeved shirt can be seen from behind standing at the edge of a bluff at left. Foliage is visible on the side of the bluff, while a schooner with no sails can be seen in the ocean below. A second boat can be seen in the ocean towards the background, while a second rocky bluff juts into the water at left beyond the first.

Photograph of a view of the Pacific Ocean, ca.1900-1950. Turbulent waters break against rocks, throwing heavy spray.

Photograph of the Pacific Ocean and sky in Astoria, Oregon, ca.1900. Light shines through the clouds above which block the sun. Below, the light refracts over gentle surf.

Photograph of a view of Pacific Coast Highway from the top of a cliff, [s.d.]. The highway curves from the foreground at left to the background at center, where it disappears around a point. Several beach houses can be seen along the road at center, and the ocean can be seen at left. In the foreground at right, a large building with Romanesque columns is visible. Two statues can be seen outside the building.

Photograph of a birdseye view of the Roosevelt Highway near the Pacific Ocean, 1930. The highway hugs the shoreline from the foreground to the background at center and is a two-lane paved road. Many automobiles can be seen on the highway, and even more are parked along the shoulders. Plant-covered hills are visible at left, while the ocean can be seen in the background at right. A small building can be seen in the foreground at right, and many beach-goers can be seen outside of it. Roosevelt Highway later became Pacific Coast Highway.

Photograph of a view of the Pacific Coast Highway and the Pacific Ocean from the top of a cliff, [s.d.]. The highway runs from the foreground at right to the background at center and is a two-lane paved road. A tall line of tree-covered mountains runs parallel to the road at left, while the ocean can be seen at right. A large rock is visible next to the highway at right, and a bridge crosses over the road in the background at center.
