Résumé : The aim of this paper is to present in a practical fashion the status of the use of remote sensing for the study of coral reef environments through the analysis of work published in the years 1980-2000. We review the scales of the potential work and of that actually conducted, the principal applications and their limiting factors. We detail these limitations which are of a technological nature (spatial and spectral resolution of sensors), as well as often of a conceptual (role of remote sensing in the study) or methodological (image processing) nature. The understanding of these limitations, in relation to the reality of the field, allows identification of work which could be undertaken in the years 2000.
Cet article présente, de façon pragmatique, le bilan de l’usage de la télédétection pour l’étude des milieux coralliens, à travers l’analyse des travaux publiés dans les vingt dernières années. Nous exposons les échelles de travail potentielles et celles réellement pratiquées, les principales applications et leurs facteurs limitants. Nous détaillons ces limites qui sont d’ordre technologique (résolutions spatiales et spectrales des capteurs), mais aussi bien souvent d’ordre conceptuel (place de la télédétection dans l’étude), ou méthodologique (traitement des images). La compréhension de ces limites, confrontées à la réalité du terrain, permet de cadrer les travaux qui pourront être menés au début du troisième millénaire.

Résumé : International audience
Time-series bathymetric data acquired from 1967 to 2011 are used to evaluate the morphological evolution of the continental shelf and upper continental slope off the city of Nice (SE France, Ligurian Sea). Mapping in water depths of 0–300 m was undertaken to identify the changing morphology of landslide scars and their erosive chutes. Quantitative Digital Terrain Model (DTM) comparisons reveal areas of erosion and deposition over intervals of 5–8 years. Sediment remobilization events on the upper slope (above depths of 200 m) are frequent and significant; landslide scars with volumes > 25,000 m3 can occur with frequencies of < 8 years. Shelf break retreat toward the coastline can reach 60 m over 7–8 years where the continental shelf is wider (> 200 m). Periods of quiescence (1980–1990 and 2006–2011) are seen to alternate with periods when rapid retrogressive failure increase sediment volumes eroded from the upper slope-shelf transition by an order of magnitude (1999–2006). Temporal variations in landslide activity were correlated to several potential triggering factors that individually would not induce failures, including earthquake activity, rapid deposition of fine-grained sediments on a steep slope, and rainfall leading to fresh groundwater circulation below the shelf. This 4D bathymetric study suggests that over the last 50 years the most important factor triggering landslides offshore Nice is overpressure due to freshwater outflows.
