2000. Variability of the stratification and circulation on the Flemish Cap during the decades of the 1950s and 1990s
Oceanographic observations on the Flemish Cap (around 47°N, 45°W) from the early-1990s to 1999 are compared to the long-term mean and to conditions during the past several decades. The mean temperature and salinity fields and their seasonal cycles were first computed and then used to construct T/S a...
