Whitlock Site AWS 8913 25/01/83 76.08 S, 168.33 E, 221 m (By barometric difference) Aerovane 00-00-00 Left in place because screws would not come out Field Calibration; Item Test Set Measured Correction Air temperature -4.8 C -4.5 C +0.3 C Pressure 954.3 mb 953.7 mb -0.6 mb Wind speed Use previous calibration Wind direction North = 346 deg, increasing clockwise +14 deg Aerovane could not be removed. The tower was leaning slightly to the north. The barrel anchors did not have weights in them and were not actually anchoring the tower. An snow anchor board to the wouth and an additional line to the battery box to the south west were installed. The tower base was frozen into the ice which was doing the actual anchoring. The snow must melt during the summer. 400 lbs of weight should carried out next year to anchor the barrels along with an entire boom assembly to replace the aerovane.
