Methane Budget

Based on data on the spatial distribution and fluxes of streaming (bubbling) methane within the Black Sea, the rate of dissolved methane inflow to Black Sea deep waters was assessed. Calculations showed that gas bubble streams annually replenish the methane budget in the Black Sea by 1.2 109 m3, or 0.9 Tg, which is considerably less than determined by known biogeochemical estimates of components of methane balance in the Black Sea.

Deze bijdrage handelt over de perikelen in de jaren dertig rond het plan om het lichamelijk overschot van de Vlaamse dichter Paul Van Ostaijen over te brengen uit het klein Waals dorp waar hij in vergetelheid begraven lag onder een houten kruis naar zijn geboortestad Antwerpen. Daar zou hij herbegraven worden op de stedelijke begraafplaats Schoonselhof onder een gepaste denksteen. Zoals meermaals het geval is bij het oprichten van publieke monumenten, verliepen – wegens onderling gekibbel en gebrek aan financiële middelen – meer dan zes jaren vooraleer de oorspronkelijke idee kon verwezenlijkt worden.Aandacht in dit artikel gaat naar Jozef Duysan, bewonderaar van de dichter en uitgesproken flamingant, die een cruciale rol speelde in de conceptie en uitvoering van het initiatief. Ten slotte beschrijft het artikel hoe deze nu bijna totaal vergeten man tijdens de Tweede Wereldoorlog in het vaarwater geraakte van de collaboratie, fungeerde als directeur van het Arbeidsamt in Antwerpen, na de oorlog veroordeeld werd en jaren lang ondergedoken leefde in die stad.________Jozef Duysan’s battle with the angel: Skirmishes around the tomb of Paul Van OstaijenThis contribution reports the vicissitudes concerning the plan dating from the nineteen thirties to transfer the mortal remains of the Flemish poet Paul Van Ostaijen from the small Walloon village where he was buried in oblivion under a wooden cross to Antwerp, the city of his birth. He was to be reburied there on the municipal cemetery Schoonselhof under a fitting memorial headstone. As frequently happens on the occasion of creating public monuments, more than six years passed before the original idea could be carried out – because of internal bickering and lack of financial means. This article focuses on Jozef Duysan, an admirer of the poet and an explicit Flemish militant, who played a crucial role in the concept and realisation of the initiative. In conclusion the article recounts how this man who has been practically completely forgotten now,  ventured into the deep waters of the collaboration during the Second World War, how he acted as director of the Arbeidsamt in Antwerp and how he was convicted after the war and lived for many years in hiding in that city.

Set Up

The diversity and degradation capacity of hydrocarbon-degrading consortia from surface and deep waters of the Eastern Mediterranean Sea were studied in time-series experiments. Microcosms were set up in ONR7a medium at in situ temperatures of 25 °C and 14 °C for the Surface and Deep consortia, respectively, and crude oil as the sole source of carbon. The Deep consortium was additionally investigated at 25 °C to allow the direct comparison of the degradation rates to the Surface consortium. In total, ~50% of the alkanes and ~15% of the polycyclic aromatic hydrocarbons were degraded in all treatments by Day 24. Approximately ~95% of the total biodegradation by the Deep consortium took place within 6 days regardless of temperature, whereas comparable levels of degradation were reached on Day 12 by the Surface consortium. Both consortia were dominated by well-known hydrocarbon-degrading taxa. Temperature played a significant role in shaping the Deep consortia communities with Pseudomonas and Pseudoalteromonas dominating at 25 °C and Alcanivorax at 14 °C. Overall, the Deep consortium showed a higher efficiency for hydrocarbon degradation within the first week following contamination, which is critical in the case of oil spills, and thus merits further investigation for its exploitation in bioremediation technologies tailored to the Eastern Mediterranean Sea.

Submarine inspections and surveys require underwater vehicles to operate in deep waters efficiently, safely and reliably. Autonomous Underwater Vehicles employing advanced navigation and control systems present several advantages. Robust control algorithms and novel improvements in positioning and navigation are needed to optimize underwater operations. This paper proposes a new general formulation of this problem together with a basic approach for the management of deep underwater operations. This approach considers the field of view and the operational requirements as a fundamental input in the development of the trajectory in the autonomous guidance system. The constraints and involved variables are also defined, providing more accurate modelling compared with traditional formulations of the positioning system. Different case studies are presented based on commercial underwater cameras/sonars, analysing the influence of the main variables in the measurement process to obtain optimal resolution results. The application of this approach in autonomous underwater operations ensures suitable data acquisition processes according to the payload installed onboard.

Prevailing View

To provide an observational basis for the Intergovernmental Panel on Climate Change projections of a slowing Atlantic meridional overturning circulation (MOC) in the 21st century, the Overturning in the Subpolar North Atlantic Program (OSNAP) observing system was launched in the summer of 2014. The first 21-month record reveals a highly variable overturning circulation responsible for the majority of the heat and freshwater transport across the OSNAP line. In a departure from the prevailing view that changes in deep water formation in the Labrador Sea dominate MOC variability, these results suggest that the conversion of warm, salty, shallow Atlantic waters into colder, fresher, deep waters that move southward in the Irminger and Iceland basins is largely responsible for overturning and its variability in the subpolar basin.
