Sur près de 15 000 kilomètres parcourus, plus de 1000 observations de mammifères marins ont été effectuées. Depuis 1994, les campagnes SCANS (Small Cetaceans in European Atlantic waters and the North Sea) ont pour objectifs d’évaluer l’abondance et la répartition des mammifères marins, mais aussi des oiseaux, tortues, grands poissons et déchets en mer. Elles sont réalisées tous les six ans pour évaluer l’état écologique de ces populations.

Although the relationships between habitats and ecosystem services (ESs) have been acknowledged, investigating spatio-temporal change in these has received far less attention. This study assesses the influence of habitat changes on ES delivery across space and time, based on two time points some 60 years apart, 1946 and 2009. A 1946 aerial photo coverage of two catchments in Scotland was used to construct digital photo mosaics which were then visually interpreted and digitised to derive historic habitat maps.
