| Summary: | nt and rates of egg production of Calanus finmarchicus southwest of Iceland. – ICES Journal of Marine Science, 57: 1727–1739.The winter distribution, seasonal vertical migration, and reproduction of Calanus finmarchicus in relation to water masses and chlorophyll a were investigated southwest of Iceland between November 1996 and June 1997 as part of the TASC programme. During winter (November/December, January/February), overwintering C. finmarchicus were generally located beyond the shelf (5000–30 000 individuals m2); by contrast, overwintering animals were usually scarce on the banks (<800–2000 individuals m2). In the Iceland Basin, overwintering C. finmarchicus resided mainly from 400 m depth to the bottom (>2000 m) at temperatures of 3–8C, whereas in the Irminger Basin the distribution was mainly 200–1800 m in waters of3–6C. During winter, most of the stock was present as C5 (84–86%), with a smaller proportion as C4 (12–14%) and females (1–2%). Overwintering animals resided mainly in water of Atlantic origin, but some animals were found in Labrador Sea Water and Iceland–Scotland Ridge Overflow Water. Ascent to upper layers |
