Report of the Regional Co-ordination Meeting for the North Sea and Eastern Arctic (RCM NS&EA) 2015

The RCM NS&EA met 31st August - 4th September 2015 at den Haag, Netherlands with 27 participants form 11 member states and autonomous regions attending, including representatives of ICES and the Commission. National correspondents from Spain, UK, Denmark, Lithuania, Germany, Sweden and the Netherlands were present. The meeting was co-chaired by Katja Ringdahl (Sweden) and Alastair Pout (Scotland). The RCM N&SEA considered the recommendations from the 11th Liasion meeting and summaries were presented of the work of expert groups and end users for the 2014-15 period to the plenary session of the meeting. The expert groups included WGCATCH, PGDATA, WKISCON2, WKRDB 2014-01, RDB–SC, STECF and the Zagreb meeting on transversal variables. ICES, as a main end user, provided feedback. A summary was presented of the progress in the regional coordination project (fishPi). This project involves over 40 participants from 12 members states from NS&EA, NA and Baltic regions, two external statistical experts, and ICES. The project has a wide scope of regional cooperation issues including sampling designs, data formats, code lists, PETS, stomach sampling, small scale and recreational sampling, and data quality software production. It has a budget of €400,000, and a one year time line and with a planned completion date of April 2016. A project with identical aims is running in paralleled in the Mediterranean and Black Sea regions The majority of the ToRs of the RCM NS&EA were addressed by three subgroups: one concerned with data analysis, one with the landing obligation, and one with issues particularly related to role and work of national correspondents

Spatio-temporal dynamics and behavioural ecology of a "demersal" fish population as detected using research survey pelagic trawl catches: The Eastern Baltic Sea cod (Gadus morhua)

Cod is usually monitored for scientific purposes using bottom trawl surveys, although its regular pelagic occurrence is well documented. Here we analysed, using Generalized Additive Models, the spatio-temporal changes in the Eastern Baltic cod adult population using pelagic catches from an acoustic survey covering 37 years and the whole central Baltic Sea. Our analysis shows that in the northern areas cod catch per unit effort (CPUE, kg h-1) was high in the early 1980s whereas it dropped and remained very low thereafter. Conversely, in the southernmost area CPUE largely oscillated after the early 1990s. Our model was able to capture key ecological features of the Baltic cod such as preferred depth of occurrence and response to hypoxic conditions. The model also revealed a clear daily cycle of CPUEs, indicating diel vertical migrations at the population level. The temporal trends of pelagic CPUEs generally followed those from the bottom trawl surveys, although differences were observed especially in the recent years with a relative decline in the cod occurring in the pelagic waters. Our results point to the great potential of acoustic survey trawl catches to complement bottom trawl surveys for investigating the spatio-temporal population dynamics and behaviour of the Baltic cod

On-line SPE-HPLC determination of phenols based on preconcentration on carbon sorbent and desorption with subcritical water

Разработан проточный сорбционно-ВЭЖХ способ определения фенола и его производных в водах. Способ включает в себя сорбционное концентрирование фенолов из 10 мл воды на пористом графитированном углеродном сорбенте Hypercarb, десорбцию субкритической водой при температуре 175 °C, фокусирование аналитов на начальном участке ВЭЖХ колонки и разделение смесью «ацетонитрил-вода». Пределы обнаружения фенолов составили 0.6-2 мкг/л. Правильность определения фенолов в водопроводной и минеральной воде подтверждена методом «введено-найдено».An on-line SPE-HPLC technique for determination of phenol and its derivatives in waters was proposed. The technique includes solid-phase extraction of phenols from 10 ml of water sample on porous graphitic carbon sorbent Hypercarb, desorption with subcritical water at 175 °C, focusing of the analytes on the initial part of the HPLC column and separation with water-acetonitrile eluent. Limits of detection were 0.6-2 µg/l. The accuracy of analysis of tap and mineral waters was proven by the method of spikes

Influence of sorbent nature on platinum group metals reversible dynamic sorption preconcentration with subsequent determination by inductively coupled plasma mass-spectrometry

Исследована сорбция Ru, Rh, Pd, Ir, Pt и Au в виде ионных ассоциатов, образованных хлоридными комплексами металлов с реагентами: третичными аминами и четвертичными аммониевыми основаниями (ЧАО). Использованы третичные амины - трибутиламин (ТБА),4-(н-октил)диэтилентриамин (ОДЭТА), и ЧАО - цетилтриметиламмоний бромид (ЦТАБ). Проведены исследования на сорбентах ДИАПАК С₁₆, ССПС MN-200 и StrataX. Изучена возможность динамического сорбционного концентрирования платиновых металлов с разбавлением в потоке. Показано, что обратимое количественное извлечение Pd, Pt и Au возможно в системе ТБА-ССПС при десорбции 1 М раствором соляной кислоты в 96 % этиловом спирте. Количественного обратимого извлечения Ru, Rh, Ir достичь не удалось.The sorption of Ru, Rh, Pd, Ir, Pt, Au as ion associates, formed by metals chloro complexes with different N-reagents, was studied. The tertiary amine - tributylamine, the quaternary ammonium compound - cetyltrimethylammonium bromide, and the triamine - 4-(n-octyl)diethylenetriamine were used as reagents to form the hydrophobic compounds with PGM chloro complexes. These compounds were extracted from acid solutions with the use of the low-polarity sorbents Diasorb С₁₆ and hypercrosslinked polysterene MN-200. Dynamic sorption preconcentration of PGM with dilution in the flow was investigated. It was revealed that only tributylamine, hypercrosslinked polysterene MN-200 and 1 M HCl in ethanol provided the quantitative and reversible sorption of Pd, Pt and Au. Quantitative and reversible extracrion of Ru, Rh, Ir was not achieved

Design of a Smart Droop Nose as Leading Edge High Lift System for Transportation Aircraft

A seamless and gapless high lift device at the wing’s leading edge has the potential for reduction of airframe noise as well as for drag. A concept of a smart leading edge device was developed, which, due to systems solutions, delivers an alternative to the droop nose device as used for the A380. The main emphasis of this new device is to realize a structure/system solution for a smooth leading surface, which can be deflected into a typical high lift application. With respect to the fact that laminarity is the only technology which has the potential for step changes in drag reduction within a suitable timeframe, smart seamless and gapless high lift devices are a mandatory enabler for future wings of significantly increased aerodynamic efficienc
