Vertical distribution patterns of copepods, chlorophyll, and production in northeastern Baffin Bay
نویسنده
چکیده
High resolution vertical distributions of chlorophyll and zooplankton were collected with an instrumented Batfish vehicle in northeastern Baffin Bay. The dominant copepod species wc1.e Calanusfinmllrchicus, Calanus glncinlis, and Calanus hyperlporeus V and VI. Copepod layers consisting of C. jkmclr-chicus and C. glncialis were commonly situated ~3-4 m above the chlorophyll maximum in a depth region corresponding to the peak in the derived vertical profile of primary production. Cnlnnus hyperhoreus V and VI coincided with the chlorophyll maximum. Estimates of daily copepod grazing rations based on daily primary production and the density of copepods, with the assumption of steady state, were ~20% body C. cl-‘.

Spatial distribution of Antarctic copepods in Fíldes Bay during summer of 2012
The Antarctic Chilean peninsula, is characterized for being stable in its oceanographic conditions. Nevertheless, its coastal zones, such as bays, may have more variable physical conditions, both spatially and temporally. It has been observed that a remarkable interaction between the oceanographic conditions and spatial distribution patterns of zooplankton occurs. However, there is no good unde...
متن کاملA Be production-rate calibration for the Arctic
We present a Baffin Bay Be production-rate calibration derived from glacial deposits in western Greenland and Baffin Island, and test our results against published Be calibration datasets to develop an Arctic Be production rate. Our calibration comprises: (i) Be measurements from moraine boulders linked to a Cdated moraine at Jakobshavn Isfjord in western Greenland, (ii) an independent and prev...
متن کاملVertical Distribution of Zooplankton and Copepod Community Structure in the Straits of Malacca
Vertical distribution of zooplankton biomass and abundance, copepod taxonomic composition and species diversity were analyzed at eight stations during an oceanographic expedition along the Straits of Malacca. Samples were collected in vertical hauls (140 μm mesh using 45 cm diameter NORPAC net) from four depth strata. Zooplankton biomass was higher at 10-20 m depth in the central and southern p...
متن کاملComparison of chlorophyll distributions in the northeastern Arabian Sea and southern Bay of Bengal using IRS-P4 Ocean Color Monitor data
Water masses of different temperature and salinity partially govern the distributions of chlorophyll concentration. In the present paper, chlorophyll concentration has been deduced over the northeastern Arabian Sea and the southern Bay of Bengal using Ocean Color Monitor (OCM) data onboard Indian Remote Sensing Series Polar satellite (IRS-P4). The chlorophyll concentration is found to be higher...
متن کاملDistribution and Ecophysiology of Calanoid Copepods in Relation to the Oxygen Minimum Zone in the Eastern Tropical Atlantic
Oxygen minimum zones (OMZs) affect distribution patterns, community structure and metabolic processes of marine organisms. Due to the prominent role of zooplankton, especially copepods, in the marine carbon cycle and the predicted intensification and expansion of OMZs, it is essential to understand the effects of hypoxia on zooplankton distribution and ecophysiology. For this study, calanoid co...
