The three-dimensional prey field of Meganyctiphanes norvegica and the escape responses of their copepod prey
(ICES CM documents, Working paper, 2004) -
Three-in-one transducer design for a triple-frequencey echo sounder
(ICES CM Documents;1989/B:8, Working paper, 1989)A design is outlined in which three different kinds of transducer elements are arranged concentrically and in near proximity. It will be possible to drive the elements simultaneously, thus forming three coaxial beams at ... -
Tilt angle measurements on herring
(ICES CM documents, Working paper, 1984) -
Tilt angles of schooling penned saithe
(ICES CM Documents;1985/B:26, Working paper, 1985)Saithe (Pollachius virens) of nearly uniform 32 cm length have been photographically observed during the daytime in an apparently free-swimming and schooling state in a pen of dimensions 90 m length, 10 m width, and 7 ... -
Timely evaluation of stock status based on scientific surveys, an update
(ICES CM documents, Working paper, 2006) -
Towards a European Marine Ecosystem Observatory (EMECO)
(ICES CM documents;2006/E:10, Working paper, 2006) -
Towards an MSY-based management of Barents Sea capelin in an ecosystem context
(ICES CM documents;2009/R:07, Working paper, 2009) -
Towards Operational Management Of Pelagic Ecosystems
(ICES CM documents;2010/A:04, Working paper, 2010)Satellite data and operational ocean models provide the necessary inputs for ecosystem models of the lower to mid- and upper trophic levels. One key explanatory variable that is usually missing to understand the dynamics ... -
Tracking changes in the ling and tusk populations using CPUE estimates from logbook data
(ICES CM documents, Conference object, 2006) -
Transport of Atlantic Water in the western Barents Sea
(ICES CM documents, Working paper, 2001)Measurements from an array of current meter moorings along a section between Norway and Bear Island indicate that the seasonal mean of inflowing Atlantic Water extends further to the north during the summer than during ... -
Transport of Atlantic water through the Barents Sea
(ICES CM Documents;2000/L:20, Working paper, 2000) -
Trawl avoidance as a source of error in estimates of the prevalence of Icthyophonus hoferi disease in Norwegian spring spawning herring (Clupea harengus L.) in the feeding area
(ICES CM Documents;1995/H:8, Working paper, 1995)Summary: Results are presented from a survey in the Norwegian Sea in the summer 1993, where the abundance and distribution of herring was investigated, using a high resolution sonar and pelagic trawling at the surface. ... -
Trawl drag area and netting geometry
(ICES CM Documents;1979/B:26, Working paper, 1979)The bag of a trawlnet is considered as an elliptical cone, its wings as merely forward extensions of this cone. The dimensions of the cone are derived from the measured wingend spread and the headline height (gape) of ... -
Trawl sampling of small pelagic species off Angola. Effects of avoidance, towing speed, tow duration and time of day
(ICES CM Documents;1997/W:12, Working paper, 1997)A series of pelagic trawl sampling trials on pelagic species distributed near surface off Angola were conducted by R/V «Dr. Fridtjof Nansen» operating a medium sized pelagic trawl with a vertical opening of about 20 m. ... -
Trends in growth and reproductive parameters of Barents Sea harp seals
(Working paper, 1993)Data from reproductive organs of Barents Sea harp seals Phoca groenlandica with corresponding age determinations have been analysed in combined samples collected during three periods: 1963-1972, 1976-1985 and 1990-1993. A ... -
Trial of a New, Split-beam Echo Sounder
(ICES CM Documents;1984/B:21, Working paper, 1984)The first at-sea trial of a new, split-beam echo sounder, the SIMRAD ES380 system, is described following a review of the split-beam principle, outline of its realization in hardware and software, and description of ... -
Trophic ecology of deepwater fishes associated with the continental slope of the eastern Norwegian Sea
(ICES CM Documents;1998/O:51, Working paper, 1998)In June 1995 and 1996 demersal fishes on the continental slope of the eastem Norwegian Sea were sampled to study distribution patterns and community structure. The diets of the more abundant slope species were characterised ... -
