Objetivo
Los hábitats marinos y sus dinámicas son difíciles de monitorear sistemáticamente, especialmente aquellos en ubicaciones remotas. Este es el caso del ecosistema subantártico del kelp gigante Macrocystis pyrifera, ya mencionado por Charles Darwin en sus relatos sobre el viaje del Beagle y registrado en las cartas náuticas realizadas durante esa expedición. Combinamos estas y otras cartas náuticas del siglo XIX y principios del siglo XX con encuestas realizadas en las décadas de 1970 y 1980, y algoritmos de detección por satélite de 1984 a 2019, para analizar la distribución del kelp a lo largo del tiempo y los factores que se correlacionan con ella.
Aim
Marine habitats and their dynamics are difficult to systematically monitor, particularly those in remote locations. This is the case with the sub-Antarctic ecosystem of the giant kelp Macrocystis pyrifera, which was already noted by Charles Darwin in his accounts on the Voyage of the Beagle and recorded on the nautical charts made during that expedition. We combined these and other nautical charts from the 19th and early 20th centuries with surveys conducted in the 1970s and 1980s and satellite detection algorithms from 1984 to 2019, to analyse kelp distribution through time and the factors that correlate with it.
