Spatially explicit estimates of length and biomass of Clupea harengus (Norwegian spring spawning herring) from acoustic and trawl surveys in the North-East Atlantic in May 2011

Acoustic estimates of herring and blue whiting abundance were obtained during the surveys using the Simrad ER60 scientific echosounder. The allocation of NASC-values to herring, blue whiting and other acoustic targets were based on the composition of the trawl catches and the appearance of echo recordings. To estimate the abundance, the allocated NASC -values were averaged for ICES-squares (0.5° latitude by 1° longitude). For each statistical square, the unit area density of fish (rA) in number per square nautical mile (N*nm-2) was calculated using standard equations (Foote et al., 1987; Toresen et al., 1998). To estimate the total abundance of fish, the unit area abundance for each statistical square was multiplied by the number of square nautical miles in each statistical square and then summed for all the statistical squares within defined subareas and over the total area. Biomass estimation was calculated by multiplying abundance in numbers by the average weight of the fish in each statistical square then summing all squares within defined subareas and over the total area. The Norwegian BEAM soft-ware (Totland and Godø 2001) was used to make estimates of total biomass.

The influence of ocean acidification on nitrogen regeneration and nitrous oxide production in the northwest European shelf sea

The assimilation and regeneration of dissolved inorganic nitrogen, and the concentration of N2O, was investigated at stations located in the NW European shelf sea during June/July 2011. These observational measurements within the photic zone demonstrated the simultaneous regeneration and assimilation of NH4+, NO2- and NO3-. NH4+ was assimilated at 1.82-49.12 nmol N/L/h and regenerated at 3.46-14.60 nmol N/L/h; NO2- was assimilated at 0-2.08 nmol N/L/h and regenerated at 0.01-1.85 nmol N/L/h; NO3-was assimilated at 0.67-18.75 nmol N/L/h and regenerated at 0.05-28.97 nmol N/L/h. Observations implied that these processes were closely coupled at the regional scale and that nitrogen recycling played an important role in sustaining phytoplankton growth during the summer. The [N2O], measured in water column profiles, was 10.13 ± 1.11 nmol/L and did not strongly diverge from atmospheric equilibrium indicating that sampled marine regions were neither a strong source nor sink of N2O to the atmosphere. Multivariate analysis of data describing water column biogeochemistry and its links to N-cycling activity failed to explain the observed variance in rates of N-regeneration and N-assimilation, possibly due to the limited number of process rate observations. In the surface waters of five further stations, ocean acidification (OA) bioassay experiments were conducted to investigate the response of NH4+ oxidising and regenerating organisms to simulated OA conditions, including the implications for [N2O]. Multivariate analysis was undertaken which considered the complete bioassay data set of measured variables describing changes in N-regeneration rate, [N2O] and the biogeochemical composition of seawater. While anticipating biogeochemical differences between locations, we aimed to test the hypothesis that the underlying mechanism through which pelagic N-regeneration responded to simulated OA conditions was independent of location. Our objective was to develop a mechanistic understanding of how NH4+ regeneration, NH4+ oxidation and N2O production responded to OA. Results indicated that N-regeneration process responses to OA treatments were location specific; no mechanistic understanding of how N-regeneration processes respond to OA in the surface ocean of the NW European shelf sea could be developed.

European Union-Latin American relations in a turbulant era. Jean Monnet/Robert Schuman Paper Series Vol. 12, Special December 2012

From the Introduction. The mere mentioning of “the Trans-Atlantic Relationship” generates a standard interpretation. Customary understanding claims that it is supposed to deal with the links between Europe and the United States (moderately expanded to include Canada, a country taken for granted). This is a view shared both in Brussels and Washington. This geographical concept very rarely refers to include the role of Mexico, for example. This “relationship” is never understood as triangular, formed by three partners (United States/Canada, Europe and Latin America/Caribbean). A quadrangular format, including Africa, is contemplated only in a bilateral sense (usually when one of the important partners (the United States or Europe) is considered as a protagonist. In sum, “Atlantis” (as an entity shared by all) is as mysterious and difficult to grasp as the myth of antiquity, as a problem that this volume surely tries to grasp and analysis.

Iceland’s contested European Policy: The Footprint of the Past - A Small and Insular Society. Jean Monnet Occasional Paper 01/2013

Introduction. Iceland’s domestic politics and foreign affairs are undergoing drastic changes. After an economic crash, violent protests on the streets of Reykjavik for the first time in Iceland’s history contributed to the defeat of the government. The party system has been altered. A turn has been taken towards Europe after the United States left the island, first by closing its military base in 2006 and then by its clear stance not to assist the country in its economic difficulties. The former close relations with the superpower are unlikely ever to be restored. The EU membership application is placing severe constraints on political parties which are split on the issue and has put in jeopardy the unity of the first left majority in the Icelandic parliament, the Althingi. Society is in a state of flux after an unprecedented economic downscaling and the collapse of almost its entire financial sector – which had boomed rapidly beginning in the mid-1990s. The credibility of politicians, the parliament and the media is in ruins. Iceland’s smallness and its location on the geographical map – one could also say the geopolitical map – has had a profound influence on its domestic and foreign affairs. Iceland is closely associated with the other Nordic states and has adopted many of their domestic characteristics, with important exceptions. On the other hand, the country has come under American influence – geographically, it straddles the Mid-Atlantic rift – and has limited its participation in the European project. Its geographical location in the middle of the North Atlantic has led to a notion that the country’s culture is unique and should be protected by all available means. Politicians continue to play the ‘nationalistic uniqueness’ card with considerable success even though the country has been swept by globalization. Rapid modernization (which only really began in the Second World War with British and American occupations) and sudden engagement with the outside world (which only extended to the general public in the last quarter of the twentieth century) are still slowly but steadily making their mark on the country’s foreign policy. The country’s political discourse and foreign policy still bear the hallmark of the past, i.e. of a small and insular society This paper will address the political developments in Iceland since the 2008 economic crash and place it in a historical context. The aim is to understand Iceland’s present foreign policy and, in particular, the highly contested decision by its government in 2009 to apply for membership of the European Union. The paper is divided into five sections in addition to this introduction and the concluding remarks. First, it starts by explaining the importance in Iceland of a political discourse based on the concept of independence which dates back to the historical narrative of the settlement period. This section will also examine Iceland’s close relations with the other Nordic states – despite important differences between it and the others. Second, the paper will analyse the importance of the party system, i.e. the dominance of the centre-right in Icelandic politics, and the changed nature of the system. Third, it examines how Iceland further distinguishes itself from the other Nordic states in many important features. Fourthly, the paper analyses the country’s three main foreign policy priorities in the post-war period, i.e. extensions of the Exclusive Economic Zone, firm defence arrangements with the US and membership of NATO, and the drive for better market access for marine products – including a partial engagement in the European project. Fifthly, the paper examines how the country’s smallness, in terms of its central administrative capacity, has affected its domestic and foreign policy-making. The concluding section summarizes the main findings concerning the political and historical obstacles that the Social Democratic Alliance faces in its hard-fought battle to change the country’s European Policy.

A Strong Europe in a Globalized World: From the Hungarian to the Polish presidency of the Council of the European Union. ACES Working Papers, 2011

On June 17, 2011, the Center for Transatlantic Relations – together with the Center for European Policy Analysis, the Polish Institute of International Affairs in Warsaw, and the Embassies of Hungary and Poland – hosted authors writing on the theme “A Strong Europe in a Globalized World,” and who offered in-depth, substantive reflections about how the United States and Europe can work together more closely in meeting global challenges. Drawing on the agendas of the outgoing and incoming EU Presidencies of the Council of the European Union – Hungary and Poland respectively – authors focused on the importance of a strong US-EU partnership in the face of mounting global challenges, from the current financial and economic crisis through the insecurities of energy markets and the promise of the Arab Spring. Authors explored in depth four key areas of shared interests: A Global Perspective (Transatlantic Partnership in a Globalized World); Achievements and Deliverables of Eastern Partnership; Euro-Atlantic Perspectives for the Balkans; and Common Challenges of Energy Security. Senior Hungarian and Polish government officials, subject matter experts, private sector actors, and think tank scholars participated.

Neighbors and other realities: The Atlantic civilization and its enemies. ZEI Discussion Paper C228, 2015

2014 was a watershed year for the geopolitical positioning of the European Union. For the first time since the end of the Cold War, Europe is no longer exporting stability but has begun to import instability in an unprecedented way. The neighborhood policy needs a fundamental review as non-European actors pursue policy concepts and strategies that run counter to EU norms and interests. ZEI Director Prof. Dr. Ludger Kühnhardt argues that the values of the Atlantic civilization have come under pressure in a world which tends to be influenced by new conflicts or a secular nature.

The Business Cycle on Both Sides of the Atlantic. Jean Monnet/Robert Schuman Paper Series Vol. 14 No. 16, August 2014

The recent economic recession, that began in the US in late 2007 and lasted eighteen months with a heavy toll on society’s wellbeing, has demonstrated the need and urgency of properly understanding the business cycle. This is important because this paper shows that the US business cycle is a leading indicator for the European Union and the Eurozone. Therefore, it can advise governments in the European continent that a change of economic tendency is taking place, which due to globalization will sooner or later affect economies and societies. Thus, understanding the business cycle will give European governments an opportunity to adjust economic and monetary policies to help soften the negative effects on European society.

The Central European Predicament. Jean Monnet/Robert Schuman Paper Series Vol. 14 No. 9, May 2014

From Introduction. Central and Eastern Europe (CEE) has experienced a very deep economic and political transformation since the beginning of the nineties. The early years of transition were characterized by big hopes for a quick and successful development. The international community, including the EU and the USA showed interest in the transformation of the region for a number of reasons. From a geopolitical perspective, the transformation was of tremendous importance as it confirmed the end of the cold war and the bipolar global system was replaced first by a unipolar superpower system and later gave way to a multipolar or a new bipolar system. This also signaled the weakness of the Soviet Union (and later Russia), as it was not able to prevent this transformation and was soon mired in a serious and long lasting economic and political crisis that undermined its international position. After the dissolution of the Soviet Union during the nineties Russia remained very weak, both economically and politically. The power vacuum and the transformation in Central Europe made the establishment of a new international economic and security structure possible. The new economic and political pattern that started to develop within the region was based on the liberal market economy model, with the objective of opening up markets and integrating the region into the world economy and the North Atlantic security structure.

Prospects for Security on the European Continent. EU Diplomacy Paper 05/2015.

This collective EU Diplomacy Paper on relations between the North Atlantic Treaty Organisation (NATO) and the European Union (EU) consists of essays written by students of the EU International Relations and Diplomacy Studies programme at the College of Europe in the class on EU-NATO relations taught by Fulbright Professor Mark Sheetz in the academic year 2014-15. It seeks to provide a blueprint of what the near future of the transatlantic alliance and of the European security framework might look like. Special attention will be given to the possible effects of Finland joining NATO, Swedish-NATO relations, the question whether NATO should continue to exist at all, and finally the use of the Common Foreign and Security Policy (CFSP) and the Common Security and Defence Policy (CSDP) in relation with the transatlantic military alliance.

Spatially explicit estimates of stock size, structure and biomass of North Atlantic albacore tuna (Thunnus alalunga) in the North Atlantic for the period 1987-2011, compiled from statistics about ICCAT fishery region L6

The development of the ecosystem approach and models for the management of ocean marine resources requires easy access to standard validated datasets of historical catch data for the main exploited species. They are used to measure the impact of biomass removal by fisheries and to evaluate the models skills, while the use of standard dataset facilitates models inter-comparison. North Atlantic albacore tuna is exploited all year round by longline and in summer and autumn by surface fisheries and fishery statistics compiled by the International Commission for the Conservation of Atlantic Tunas (ICCAT). Catch and effort with geographical coordinates at monthly spatial resolution of 1° or 5° squares were extracted for this species with a careful definition of fisheries and data screening. In total, thirteen fisheries were defined for the period 1956-2010, with fishing gears longline, troll, mid-water trawl and bait fishing. However, the spatialized catch effort data available in ICCAT database represent a fraction of the entire total catch. Length frequencies of catch were also extracted according to the definition of fisheries above for the period 1956-2010 with a quarterly temporal resolution and spatial resolutions varying from 1°x 1° to 10°x 20°. The resolution used to measure the fish also varies with size-bins of 1, 2 or 5 cm (Fork Length). The screening of data allowed detecting inconsistencies with a relatively large number of samples larger than 150 cm while all studies on the growth of albacore suggest that fish rarely grow up over 130 cm. Therefore, a threshold value of 130 cm has been arbitrarily fixed and all length frequency data above this value removed from the original data set.
