AB  - <jats:p>Using 13 samples collected from a 4.1 meter profile in a welldated and stable New Zealand fluvial terrace, we present the first longterm accumulation rate for meteoric <jats:sup>10</jats:sup>Be in soil (1.68 to 1.72 × 10<jats:sup>6</jats:sup> at/(cm<jats:sup>2</jats:sup>·yr)) integrated over the past ∼18 ka. Sitespecific accumulation data, such as these, are prerequisite to the application of meteoric <jats:sup>10</jats:sup>Be in surface process studies. Our data begin the process of calibrating longterm meteoric <jats:sup>10</jats:sup>Be delivery rates across latitude and precipitation gradients. Our integrated rate is lower than contemporary meteoric <jats:sup>10</jats:sup>Be fluxes measured in New Zealand rainfall, suggesting that longterm average precipitation, dust flux, or both, at this site were less than modern values. With accurately calibrated longterm delivery rates, such as this, meteoric <jats:sup>10</jats:sup>Be will be a powerful tool for studying rates of landscape change in environments where other cosmogenic nuclides, such as in situ <jats:sup>10</jats:sup>Be, cannot be used.</jats:p>
