The data provide 27 well\u2010dated directions from historical or <jats:sup>14<\/jats:sup>C dated flows which, together with 6 directions previously gathered from the same flows by Johnson et al. (1998), yield the first paleomagnetic directional record of the last 3 ka from the Atlantic Ocean. Within\u2010flow directions are consistent, suggesting that inclination swings from 60\u00b0 to 25\u00b0 and declination changes between \u221210\u00b0 to 20\u00b0 reflect variations in the geomagnetic field over the last 3 ka. To a first approximation, the declination record is consistent with predictions from CALS3k.4 and gufm1 global field models. Conversely, inclination values are lower than model predictions at two different ages: 1) four sites from the 1652 AD flow yield I = 48\u00b0 instead of I = 63\u00b0 predicted by gufm1; 2) data from several flows nicely mimic the inclination minimum of 800\u20131400 AD, but inclination values are lower by \u223c10\u00b0 than CALS3k.4 model predictions. By interpolating a cubic spline fit on declination \/ inclination versus age data, we tentatively infer the directional evolution of the geomagnetic field at the Azores from 1000 BC to 1600 AD. The obtained curve shows three tracks in virtual overlap during the 1000\u2013800 BC, 800\u2013500 BC, and 400\u2013700 AD time spans.<\/jats:p>","DOI":"10.1029\/2012jb009285","type":"journal-article","created":{"date-parts":[[2012,6,4]],"date-time":"2012-06-04T18:15:54Z","timestamp":1338833754000},"source":"Crossref","is-referenced-by-count":22,"title":["Paleomagnetic secular variation at the Azores during the last 3 ka"],"prefix":"10.1029","volume":"117","author":[{"given":"Anita","family":"Di Chiara","sequence":"first","affiliation":[]},{"given":"Fabio","family":"Speranza","sequence":"additional","affiliation":[]},{"given":"Massimiliano","family":"Porreca","sequence":"additional","affiliation":[]}],"member":"13","published-online":{"date-parts":[[2012,7,12]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0024\u20104937(75)90008\u20100"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1029\/95JB00148"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1144\/gsjgs.138.3.0281"},{"issue":"2","key":"e_1_2_8_5_1","first-page":"341","article-title":"Magnetic study of the Furna caldera (Azores)","volume":"15","author":"Blanco I.","year":"1997","journal-title":"Ann.
