Traditional acoustic surveys to assess fish abundance can be limited by the surface blind zone and the seabed dead zone. The blind zone is the unobservable layer above the transducer and in its nearfield, and the dead zone is the layer closest to the seabed, where only a fraction of the backscatter from fish can be separated from that of the seabed... An acoustically estimated abundance is biased if fish are migrating in and out of the dead zone...  1, fiche 1, Anglais, - seabed%20dead%20zone

Traditional acoustic surveys to assess fish abundance can be limited by the surface blind zone and the seabed dead zone. The blind zone is the unobservable layer above the transducer and in its nearfield, and the dead zone is the layer closest to the seabed, where only a fraction of the backscatter from fish can be separated from that of the seabed … fish in the blind zone often react to an approaching vessel...  1, fiche 2, Anglais, - surface%20blind%20zone

Record number: 4, Textual support number: 1 CONT

La capa de agua superficial que tiene suficiente luz para la fotosíntesis se llama "zona eufótica", y allí donde el agua es muy limpia y transparente puede alcanzar desde la superficie hasta los 100 - 130 metros de profundidad. La zona de penumbra es la zona oligofótica, y por debajo y hasta el fondo se encuentra la zona afótica, en la que no hay luz de origen solar.  3, fiche 4, Espagnol, - zona%20af%C3%B3tica

index fossil : A [microfossil] that identifies and dates the strata or succession of strata in which it is found; esp. any fossil taxon(...) that combines morphologic distinctiveness with relatively common occurrence or great abundance and that is characterized by a broad, even worldwide geographic range and by a narrow or restricted stratigraphic range(range zone) that may be demonstrated to approach isochroneity.  2, fiche 6, Anglais, - index%20microfossil
