“…There is a long tradition in oceanography of using ocean colour and temperatures to classify ocean waters (Helland-Hansen 1916;Jerlov 1968) that continues into modern satellite observations. Satellite ocean colour has been used to infer the dynamics of river plumes, coastal upwelling zones and mesoscale eddies (Mcclain 2009;Geiger et al 2011).…”

Summary1. Categorical landscapes are powerful environmental partitions that index complex biogeochemical processes that drive terrestrial species distributions. However, translating landscapes into seascapes requires that the dynamic nature of the fluid environment be reflected in spatial and temporal boundaries such that seascapes can be used in marine species distribution models and conservation decisions. 2. A seascape product derived from satellite ocean colour and sea surface temperature partitioned mid-Atlantic coastal waters on scales commensurate with the Atlantic Sturgeon migration. The seascapes were then matched with acoustic telemetry records of Atlantic Sturgeon to determine seascape selectivity. To test for selectivity, we used real-time satellite seascape maps to normalize the sampling of an autonomous underwater vehicle that resampled similar geographic regions with time varying seascape classifications. 3. Our findings suggest that Atlantic Sturgeon prefer one seascape class over those available in the coastal ocean, indicating selection for covarying environmental properties rather than geographical location. 4. The recent listing of Atlantic Sturgeon as Endangered throughout much of their United States range has highlighted the need for improved understanding of marine habitat requirements to reduce interactions with anthropogenic stressors. Narrow dynamic migration corridors may enable seascapes to be used as a daily decision tool by industry and managers to reduce interactions with this imperilled species during coastal migrations.

“…I The Norwegian Sea i 1909 påsto Helland-Hansen og Nansen at der utvilsomt var en sammenheng mellom atlanterhavsvannet i Norskehavet og lufttemperaturen i Norge. 88 De hadde også undersøkt om det fantes sammenhenger mellom disse svingningene og variasjon i fiskeriene og skogveksten i Norge: «og det har vist sig at vaere en slig overensstemmelse tilstede i langt høiere grad, end vi til at begynne med hadde taenkt os mulig».…”
