We investigate the sensitivity of the thermohaline circulation (THC) with respect to a subpolar salinity perturbation. Such perturbation simulates a fresh water release caused by retreating glaciers or anomalous sea ice. The feedback mechanisms amplifying or damping the initial anomaly are analyzed in the coupled ocean-atmospheresea ice model. Their understanding is essential for modelling clim...

The paper is focusing on transportation system architecture for intelligent management, especially in sea transport and transportation technology. Moreover control models of large-scale distributed enterprises systems and transport active knowledge base management model have been presented.

Sea salt and mineral dust records as represented by Na and Ca concentrations, respectively, in Greenland and Antarctic ice cores show pronounced glacial/interglacial variations. For the Last Glacial Maximum (LGM) mineral dust (sea salt) concentrations in Greenland show an increase of a factor of approximately 80 (15) compared to the Holocene and significant shifts by a factor of 15 (5) during D...

[1] Using in situ data from 88 cruises from 1987 to 2009 in the East China Sea, downstream nutrient flux (the product of velocity and nutrient concentration) and nutrient transport (integration of flux over a section) by Kuroshio were examined. The presence of a maximum nutrient flux core in the middle layer was confirmed. Seasonal variation in the nutrient flux was not significant and was much...

Multiple equilibria in a coupled ocean–atmosphere–sea ice general circulation model (GCM) of an aquaplanet with many degrees of freedom are studied. Three different stable states are found for exactly the same set of parameters and external forcings: a cold state in which a polar sea ice cap extends into the midlatitudes; a warm state, which is ice free; and a completely sea ice–covered ‘‘snowb...

According to the midterm review of the EU White Paper on Transport, Short Sea Shipping is expected to grow at a rate of 59%, in metric tones, from 2000 to 2020. We consider that the overall expected growth in freight exchanges is of 50% (also in volume) sea transport is one of the most feasible ways to reduce traffic congestion on European roads. However its clear adoption as a transport altern...

In terms of transportation, safety and security issues are particular concern. The shipping system is an important factor that must be considered as a basis benchmark for decision-making in determining the feasibility both facilities form ships infrastructure such navigation systems, human resources involved it. Indonesia has sovereignty over entire Indonesian sea area, so significant role mean...
