1824-08-27T12:00: EXTRACT UIT HET JOURNAAL VAN ZM FREGAT MARIA REIGERSBERGEN OP EENE REIS UIT TEXEL NAAR OOST-INDIEN LANGS DE KUST VAN GUINEA VAN DAAR OM KAAP HOORN NAAR VALPARAISO EN LIMA EN VERDER DOOR DEN STILLE OCEAAN. SAMEN MET DE POLLUX (KAPITEIN LUITENANT C.N. EEQ). J.P. MULLER AAN BOORD MET DE STUURMANSINSTRUMENTEN, BESTAANDE UIT: 3 TIJDMETERS, 1 THERMOMETER, 1 SEXTANT, 1 AZIMUTHKOMPAS, 1 STUURKOMPAS VOLGENS MANIER VAN STEBING VERBETERD DOOR KLEMAN ALSMEDE DE OOSTINDISCHE PILOT. LATER KWAM NOG EEN ZENDING INSTRUMENTEN UIT ENGELAND, BESTAANDE UIT: 1 SEXTANT, 1 BAROMETER, 1 ACROMATISCHE KIJKER, 1 HYGROMETER. DAAR WIJ BIJNA GEEN ANDERE DAN ENGELSCHE KAARTEN AAN BOORD HADDEN, ZO BEREKENDEN ONZE LENGTE VOLGENS DEN MERIDIAAN VAN GREENWICH. MULLER HAD DE TAAK DE TIJD TE METEN: NO 22 LIEP ZEER IRREGULIER, NO 27 DAGELIJKSE VERTRAGING VAN 74 SECONDEN, NO 39 HAD EEN DAGELIJKSE VERTRAGING VAN 63 SECONDEN.

| 4 | Wind direction | dd | deg | Wind direction (from which the wind is blowing) in whole degrees from: 1-360; 361 = calm, 362 = variable. It is not clear from many logbook entries whether the wind direction has been corrected for the magnetic variation (or declination). To avoid any misunderstanding, all winds from reports that included a valid position in the period 1750-1854 were corrected. All other wind directions are given without being corrected. | ||

| 11 | Declination | Decl | deg | It is generally accepted by the CLIWOC team that the wind directions, reported by the ships officers, were relative to the magnetic North direction. Navigators were well aware of the difference between the true and magnetic north direction, but the compasses (we assumed that the bearing-compasses were mostly used for determining the wind direction) were not always adjusted. Therefore the wind direction has to be corrected. The magnetic declination (or variation, as it is known on board ships) is given for the whole CLIWOC period (1750-1850) for every 5x5 degree square. The number was added to the wind direction to get the true wind direction. | ||
