This paper describes a method for measuring nearshore ocean wave characteristics with a land-based, long-period vertical seismometer. The wavemeter system has proven to be highly reliable and produces continuous wave observations at low cost. It is now operational at six Coast Guard stations along the Oregon and Washington coasts; data...
This report is an intermediate step in analyzing part of the hydrographic data from the 1972 Coastal Upwelling Experiment (CUE) off the coast of Oregon. It presents the author's interpretation of the vertical distribution of temperature, salinity and sigma-t along lines occupied on hydrographic cruises by R/V Yaquina during CUE....
Hydrographic and optical measurements were made in situ in the Congo River and the Angola Basin during May 1978.

This is the second year we have had a series...
Catch data for albacore troll boats were collected from fishermen's logbooks and from dockside
interviews during the 1968, 1969, and 1970 seasons. Fishing powers of these boats were calculated and used to determine the 10 most successful and 10 least successful fishermen (highliners and lowliners, respectively) who fished off Oregon...
The purpose of this study is to examine the hypothesis that diel variations occur in the catches of albacore by boats trolling surface jigs off Oregon. Although albacore fishermen talk of "morning bites" and "evening bites," no published data exist, to our knowledge, confirming these trends.
Studies on the feeding...

fossils of simple organisms are found in rocks deposited in hydrothermal environments. Biochemical experiments have
shown that thermal...

Our primary purpose in developing this instrument is to measure
vertical temperature fluctuations in the ocean to the smallest scales at
which they exist. This goal dictates the basic concept of the instrument,
as C. S. Cox saw in the 1960's. Vertical temperature changes are seen
as changes with time...
