Subject: COAST Flight Report - May 16
Two COAST flights were conducted on May 16, 2001 with the University of North Carolina Piper Seneca research aircraft. Both flights originated and terminated at the Corvallis airport (CVO). The pattern covered was the Big Box; all eight lines were flown. The southern four lines (5 through 8) were flown between 1200 and 1400 PDT, and the northern four lines (4 through 1) were flown between 1600 and 1800 PDT. Skies were clear and winds at the flight level of 300m were low, mostly westerly at about 5 knots. Data collected include: Ocean surface temperature (remotely sensed SST) and subsurface temperature (with AXBTs); horizontal wind, air temperature, humidity and pressure, all at flight level (i.e. the position of the aircraft). We ran the new hyperspectral ocean color radiometers to test their functioning, but we did not collect useful, calibrated data on these flights.
A total of 49 AXBTs were deployed; 47 provided useful data and 2 were failures (i.e. no data transmission was received aboard the aircraft). The spatial coverage was from the 50m isobath on each line westward to at least 125W. The three southernmost lines extended a bit farther to the west, following the Big Box pattern. The only AXBT station at which we did not get data was at the 50m isobath on Line 4, just northwest of the Yaquina River mouth. The number of successful AXBTs deployed on each line is as follows:Line 1: 6 Line 2: 6 Line 3: 6 Line 4: 5 (out of six stations) Line 5: 7 Line 6: 7 Line 7: 5 Line 8: 5
Four vertical profiles of atmospheric variables were measured from 60m to at least 800m altitude. Two of these were near 125W and two were near the coastline. No atmospheric temperature inversion was seen.
Some photography with a hand-held digital camera (2 megapixel images) was done. Pictures of the sea surface, the coastline and the R/V Thompson at the dock were taken.
