Pelagic respiration in the coastal zone of the southern Baltic Sea

Ecohydrology & Hydrobiology, 2015
Abstract Respiration measurements were carried out year round at two stations located in the coastal zone of the southern Baltic Sea. Study sites differed with their characteristics: first one was located in the coastal zone of the Gulf of Gdansk near the town of Sopot (54°27′ N, 18°35′ E), second one was located in the coastal waters of the southern

The pelagic system in the photic zone of the tropical Atlantic

Hydrobiological Bulletin, 1980
A multidisciplinary study of the carbon budget in the upper 300 meter of permanently stratified waters was started by two NECTAR-expeditions (North Equatorial Current Trans Atlantic Research) with HMS TYDEMAN in 1977 and 1978 (BAARS, ZIJLSTRA and TIJSSEN, 1979). In 1979 additional measurements were performed during the Gulf of Guinea-expedition with MS

Bacterioplankton in the littoral and pelagic zones of subtropical shallow lakes

Hydrobiologia, 2010
We measured bacterioplankton (phylotypes detected by fluorescent in situ hybridisation, morphometric forms, abundance and production) in samples collected in summer in the littoral and pelagic zones of 10 subtropical shallow lakes of contrasting area (from 13 to 80,800 ha). Compared to the pelagic zones, the littoral zones were overall characterised by

Bacterial and primary production in the pelagic zone of the Kara Sea

Oceanology, 2010
Data on the bacterial and primary production, which were obtained simultaneously for the same water samples, are presented for three regions of the Kara Sea. The samples were collected for the transect westwards of the Yamal Peninsula, along the St. Anna Trough, and the transect in Ob Bay.

Metabolic suppression in the pelagic crab, Pleuroncodes planipes, in oxygen minimum zones

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2018
The pelagic red crab, Pleuroncodes planipes, is abundant throughout the Eastern Tropical Pacific in both benthic and pelagic environments to depths of several hundred meters. The oxygen minimum zones in this region reaches oxygen levels as low as 0.1kPa at depths within the crabs vertical range. Crabs maintain aerobic metabolism to a critical PO2 of ~0.

Peculiarities of phenology of the primary production process in the pelagic zone of Lake Onega

Biology Bulletin, 2015
The peculiarities of the phenology of the primary production process of phytoplankton have been studied for a large northern lake. The major seasonal events ofthe primary production process and the seasonal dynamics of the abiotic and biotic environmental factors have been-described using the average multiyear curves of the studied parameters in the ...

Wind on lakes brings predator and prey together in the pelagic zone

Canadian Journal of Fisheries and Aquatic Sciences, 2015
Wind blowing over the pelagic zones of stratified lakes creates recirculating water currents. In Lake Opeongo, we observed the effects of these currents on four different trophic levels using a variety of methods (acoustic Doppler current profiler, optical plankton counter, hydroacoustics, telemetry, and netting programs).

Phosphorus Fluxes in the Pelagic Zone of the Black Sea

2017
On the basis of these long-term observations of hydrophysical, hydrochemical and biological structure of water the seasonal variability of the upward, regeneration, sedimentation and fluxes of phosphorus from external sources in the photosynthetic zone in the deepwater area of the Black Sea was established.

Bacterial Cycling of Matter in the Pelagic Zone of Aquatic Ecosystems

1990
This paper discusses the role of bacteria in influencing the patterns of organic and inorganic matter fluxes in pelagic ecosystems of lakes and oceans. We find that the ecological and biogeochemical roles of bacteria vary greatly in response to the nutrient and trophic scenarios in the bacterium’s microenvironment.

Fish effects on trophic relationships in the pelagic zone of lakes

Hydrobiologia, 1997
To examine the relationships between the biomass of pelagic communities and to study how these relationships differ between lakes with different fish assemblages, we used data on nutrients, chlorophyll, zooplankton, and fish from 96 Argentinean lakes and reservoirs.
