Assimilation rates of 15N-labelled ammonium, urea, and nitrate by plankton in the upper euphotic zone were measured in 2 summer, 2 winter, and I spring cruise in the central North Pacific Ocean. Average rates of ammonium plus urea assimilation could not be determined precisely, but were estimated to
The number, size, and carbon and nitrogen contents of eggs in the pouches of a euphausiid crustacean, Nemat~ce//8 di/ficili~ IL~s~, were examined. A clear linear relationship exists between the number of eggs in the pouch and the body weight of the maternal euphausiid. The eggs are not spherical in
Analysis of video recordings of swimming in abyssal grenadiers __Coryphaenoides__ spp. revealed site differences in tailβbeat frequencies. At the highly oligotrophic deep central North Pacific (CNP; 5800βm depth) station fishes had significantly lower tailβbeat frequencies (0Β·73βΒ±β0Β·02βHz, meanβΒ±βs.
This study compares the small-scale (IOO's to 1000's of meters) horizontal spatial distribution of zooplankton from stations in the California Current (29~ 118~ and in the North Pacific Central Gyre (31~ 155Ow). Patterns were inferred from the spacing of vertical tows and the variability in abundanc
