Resumo:  Core description is used extensively by sedimentologists to yield critical information from sediments. It consists of a naturalistic description of the visual and textural characteristics of the sediment. It is generally a manual procedure. However, digital core descriptions are now required re manage data processing. Hand-written description can be keyed into a computer, but it is tedious and time consuming. Moreover, recording and typing errors can occur. A system is presented for digital description of sediment cores using a bar code principle. It can be used in the laboratory as well as on board vessels. It comprises a box inside which the half-core can be placed. A ruler and several sets of bar codes are printed on the inside box top. Bar codes are read by a waterproof sensor pencil that is interfaced with a PSION 3A Docket computer. The software mimicks the traditional method of cope description, the geologist answering questions using the optical pencil. It offers versatility and is designed with the geoscientist's need for flexibility and ease of use in mind. It allows computerised core data management and is highly upgradable. It can help to harmonise core description and to compare it with core data provided by the new multiparameter measurement systems. Detailed log plots no longer require tedious coding. Logmeter data can be used to automatically create customized, full-featured log graphs displaying lithology, descriptions, curves, histograms, graphic symbols and attractive legends, using commercial or dedicated softwares.

Le logmètre est un outil de saisie de données basé sur l'utilisation de codes-barres. Il peut être utilisé indifféremment à bord des navires ou en laboratoire pour la description des carottes de sédiments. Le système se présente comme un boîtier à l'intérieur duquel on place la demi-carotte à décrire. Le couvercle intérieur du boîtier comporte une règle graduée et différents ensembles de codes-barres qui sont lus au moyen d'un stylo laser interfacé avec un ordinateur de poche de type Psion 3A. L'ordinateur est programmé pour reproduire une séquence de description type. L'opérateur répond aux questions en utilisant soit le crayon optique, soit le clavier. Ce système simple et évolutif permet d'harmoniser les descriptions de carottes en vue de leur traitement informatique et apporte un gain de temps et de fiabilité par rapport à la procédure manuelle classique.
