Additional wind measurements on shore were made by 

 the Marine Meteorological Station at Newport, Oreg. Data 

 from a tide gage at Newport were used to measure the varia- 

 tion in sea level associated with upwelling. Variations in slope 

 of the sea surface was monitored by comparison of tide gage 

 data with pressures recorded by the instruments moored at sea. 



Synoptic observations over a larger region were made 

 both by ship and aircraft. The three research vessels — Cayuse, 

 Yaquina, and Oceanographer — made repeated detailed hy- 

 drographic sections through the area to define the density and 

 nutrient fields and their variations. An instrumented research 

 aircraft from the National Center for Atmospheric Research 

 was used to obtain synoptic maps of ocean surface tempera- 

 ture, as well as flight-level air temperature, relative humidity, 

 and winds. 



Drogues were used to study the flow in the near-surface 

 Ekman layer. Upwelling patches, plumes, or other features of 

 interest revealed by the aircraft or ship surveys were investi- 

 gated in detail by the research vessels. Profiling current meters, 

 expendable BT's, and other instruments were kept aboard the 

 ships for this purpose. Two or three spare instrumented moor- 



ings were kept aboard the Yaquina for short-term deployment 

 to study such transient features. 



From May through October 1972, the RV Yaquina of 

 Oregon State University (OSU) made its series of cruises that 

 formed part of CUE-I. The purposes of the cruises were to 

 obtain hydrographic data in the grid adjacent to the Oregon 

 coast. Current meters of the CUE-I array were moored and 

 recovered during some of the cruises. In addition to hydro- 

 graphic and current data, water samples for optics, phyto- 

 plankton, and nutrient analyses were collected on several 

 cruises. Also while the ship, was underway, a continuous nu- 

 trient analysis of the water was made at 2 meters. 



On the July 10-18, and the July 31 to August 7 cruises 

 (Cruises Y7207B and Y7201E), vertical current meters were 

 deployed and recovered. 



In addition to the sampling done by OSU the SODS buoy 

 was moored at about 44°39'N, 124°30'W in the CUE-I re. 

 gion to observe oscillations in the thermocline and to explore 

 what appeared to be a bottom mixed layer. 



Another salinity-temperature-depth study of the area was 

 made by NOAA's Pacific Oceanographic Laboratory (POL) 

 using the RV Oceanographer (fig. 41).
