Turbulent Mixing in the Seasonally-stratified Western Irish Sea: a...

By: T. P. Rippeth; J. H. Simpson; M. R. Palmer; K. L. Stansfield

Description: School of Ocean and Earth Science, National Oceanography Centre, European Way, Southampton, SO14 3ZH, UK. The seasonal thermocline in shelf-seas represents an important biogeophysical barrier to the vertical flux of nutrients into the photic zone. Episodic weakening of this barrier plays an important role in sustaining the sub-surface chlorophyll maximum in summer and hence impacts the carbon draw-down in the seasonally-stratified zones of the shel...

Tidal Forcing, Energetics, and Mixing Near the Yermak Plateau : Vo...

By: A. K. Peterson; M. Müller; I. Fer

Description: Geophysical Institute, University of Bergen, Bergen, Norway. The Yermak Plateau, located northwest of Svalbard in Fram Strait, is the final passage for the inflow of warm Atlantic Water into the Arctic Ocean. The region is characterized by the largest barotropic tidal velocities in the Arctic Ocean. Internal waves generated in response to the tidal flow over this topographic feature locally contribute to mixing and remove heat from the Atlantic Wat...

Variability of Synoptic-scale Quasi-stationary Thermohaline Strati...

By: U. Lips; T. Liblik

Description: Marine Systems Institute, Tallinn University of Technology, Akadeemia Road 15a, 12618 Tallinn, Estonia. We present and analyze high-resolution observational data of thermohaline structure and currents acquired in the Gulf of Finland (Baltic Sea), using an autonomous buoy profiler and bottom-mounted acoustic Doppler current profiler during July–August 2009. Vertical profiles of temperature and salinity were measured in the upper 50-m layer with a 3 h time...

Biogeography of Planktonic Bacterial Communities Across the Whole ...

By: M. Fusi; M. Barbato; S. Borin; G. Merlino; F. Mapelli; R. Alvariño; M. M. Varela; M. Álvarez; D. Daffonchio

Description: Department of Food, Environmental and Nutritional Sciences, DeFENS, University of Milan, Via Celoria 2, 20133 Milan, Italy. Bacterial population distribution in the Mediterranean Sea has been mainly studied by considering small geographical areas or specific phylogenetic groups. The present study is a molecular microbiology investigation aimed to identify the environmental factors driving total bacterioplankton community composition of seawater samples c...

A Study on Distribution of Chlorophyll-A in the Coastal Waters of ...

By: N. Bin Abu Bakar; S. Jamshidi

Description: School of Physics, Universiti Sains Malaysia, 11800 USM, Penang, Malaysia. Phytoplankton as chlorophyll-containing organisms is the first step of production in most marine processes and food chains. Nutrient enhancement in the seawater due to the discharge of agricultural, industrial, and urban wastes threatens the Caspian Sea environment. Increasing concentrations of chlorophyll-a in seawater, in reaction to the elevation of nutrient supply can ...
