The Urania basin is a hypersaline sulfidic brine lake at the bottom of the eastern Mediterranean Sea. Since this basin is located at a depth of approximately 3,500 m below the sea surface, it receives only a small amount of phytoplankton organic carbon. In the present study, the bacterial assemblages at the interface between the hypersaline brine and the overlaying seawater were investigated. T...

Wave breaking on the surface of the ocean results in significant transfer of mass, momentum, heat and energy across the air-sea interface. However, understanding the physics of these phenomena remains a challenge, as both the measurement and simulation of the relevant processes are highly complex. Recent numerical studies have begun to investigate the air-water coupling during the breaking proc...

The objective of this report is to document progress since IWTC-V in this thematic area from experimental, observational, empirical, theoretical, and numerical perspectives. The report begins by describing progress in upper-ocean processes that include the oceanic mixed layer (OML) and the thermocline. This section is followed by a discussion of the air-sea interface that includes surface winds...

Advances in the visualization and prediction of turbulence are shedding new light on mass transfer in the turbulent boundary layer. These discoveries have important implications for many topics in environmental science and engineering, from the transport of earth-warming CO2 across the sea-air interface, to nutrient processing and sediment erosion in rivers, lakes, and the ocean, to pollutant r...

Food webs near the interface of adjacent ecosystems are potentially subsidised by the flux of organic matter across system boundaries. Such subsidies, including carrion of marine provenance, are predicted to be instrumental on open-coast sandy shores where in situ productivity is low and boundaries are long and highly permeable to imports from the sea. We tested the effect of carrion supply on ...

A computational approach is presented for steady Dupuit interface flow where the aquifer extends below the sea. A detailed approach is outlined to determine the head at the coastline so that the solution below the leaky seabed may be combined with any type of steady Dupuit interface flow in the aquifer below the land. The method allows for any inland boundary condition including specified head ...

The strengthening of concrete structures externally bonded with fiber reinforced polymer (FRP) sheet is increasingly being used for repair and rehabilitation of existing structures. This paper provides information in the area of long-term durability of FRP-concrete interface externally bonded with FRP composite sheet. It mainly discusses and summarizes the influence of harsh environmental expos...

Accessing real time data from a marine sensor network (MSN) can be a challenge. Open access to real time data using interoperable internet technologies is one of the major demands. The IEEE 1451 Smart Transducer Interface Standards [1,2,7] specify a standard API (application processor interface) process to discover and access sensor data by using an HTTP connection. This paper presents an HTTP ...
