Ökologische Leitplanken für den Tiefseebergbau - Endbericht Kurzbeschreibung Dieser Bericht ist ein Ergebnis des Forschungs- und Entwicklungsprojektes "Ökologische Leitplanken für den Tiefseebergbau", Oktober 2015 bis Dezember 2017, in Auftrag gegeben durch das Umweltbundesamt, UBA. Aufgrund des in den letzten Jahren wiedererwachten Interesses für einen Abbau von Rohstoffen in der Tiefsee, und Anstrengungen, den notwendigen Rechtsrahmen in nationalen und internationalen Gewässern zu schaffen, wird jetzt dringend auch ein Konzept für den effektiven Schutz der Meeresumwelt vor den Folgen des Rohstoffabbaus erforderlich. Im sogenannten "Gebiet", dem Meeresboden jenseits nationaler Grenzen, hat die Internationale Meeresbodenbehörde, ISA, die Aufgabe, den Meeresboden und seine Rohstoffe im Namen von und zum Vorteil der gesamten Menschheit (‘for the benefit of mankind as a whole‘) zu verwalten. Dazu gehört der Erlass von Regeln, Bestimmungen und Verfahren, welche die Auswirkungen der mit der Erkundung und dem Abbau von Rohstoffen im Gebiet zusammenhängenden Tätigkeiten in einem Rahmen hält, welcher die Vorgaben für den "effektiven Schutz der Meeresumwelt vor den Folgen der Tätigkeiten", wie im internationalen Seerecht gefordert, einhält. Der vorliegende Text zeigt Möglichkeiten auf, wie die ISA mit dem Instrumentarium des modernen vorsorgenden und präventiven Umweltmanagements die regulatorische Kontrolle über die Umweltbelastungen durch Tätigkeiten im Gebiet ausüben kann. Angesichts der großen Wissenslücken über die potentiell betroffenen Tiefseeökosysteme und die möglicherweise eingesetzte Technik scheint es allerdings zur Zeit unmöglich, auch mit den besten Verfahren den Grad der zu erwartenden Umweltschäden einzuschätzen. Daher ist schon der Weg das Ziel, indem die ISA sich als moderne, umweltbewusste Organisation präsentiert, welche den Vorsorgeansatz und internationale Verpflichtungen zum Schutz der Meeresumwelt und zur nachhaltigen Entwicklung ernst nimmt und ihr Mandat unter Einbeziehung der derzeitigen und voraussichtlich zukünftigen Veränderungen der Meeresökosysteme bis in die Tiefsee ausübt. Abstract This report presents findings from the research and development project "Ecological Safeguards for Deep Seabed Mining" commissioned by the German Environment Agency (UBA) to the Institute for Advanced Sustainability Studies (IASS) (October 2015 - December 2017). Interest in seabed mineral mining has renewed in recent years for various reasons and new offshore mining legislation is currently being developed for national and international waters. For this reason, agreement on the meaning of ‘effective protection of the marine environment from adverse effects arising from activities’ related to mining is needed. The International Seabed Authority (ISA) is mandated to manage access to and benefits from the seabed, subsoil and its mineral resources in the Area on behalf of mankind as a whole. This legal mandate comprises the development of rules, regulations and procedures for mining-related activities in the Area, which must prevent, reduce and control harm to the marine environment and ensure that such harm does not breach the standard of ‘effective protection’. The present text provides suggestions for how the ISA could effectively regulate the environmental effects of activities in the Area using a toolkit of modern, precautionary and preventive governance and management instruments and measures. However, due to large gaps in ecological knowledge and technical experience pertaining to the deep sea, it is currently impossible to predict with any certainty the degree of risk mining activities pose to deep sea ecosystems. By developing such a toolkit, the ISA could spearhead a modern, comprehensive approach to precautionary governance of the Area in line with today’s environmental challenges. 4 Ökologische Leitplanken für den Tiefseebergbau - Endbericht Table of Contents Table of Contents ............................................................................................................................................. 5 List of Figures .................................................................................................................................................... 9 List of Tables ................................................................................................................................................... 10 List of Abbreviations ....................................................................................................................................... 11 Zusammenfassung .......................................................................................................................................... 13 Summary ......................................................................................................................................................... 31 1 Introduction .......................................................................................................................................... 45 1.1 Deep seabed mining - development of a new industry in sensitive ecosystems ................. 45 1.2 The environment of deep seabed mineral resources ........................................................... 46 1.3 The legal framework ............................................................................................................. 47 1.3.1 The Common Heritage of Mankind .................................................................................. 47 1.3.2 Development of the Mining Code .................................................................................... 48 2 The Knowledge Base for Developing Ambitious Environmental Standards ......................................... 50 2.1 Development towards Deep Seabed Mineral Mining .......................................................... 50 2.1.1 Introduction ..................................................................................................................... 50 2.1.2 South West Pacific ............................................................................................................ 50 2.1.3 South East Pacific ............................................................................................................. 54 2.1.4 North Pacific ..................................................................................................................... 54 2.1.5 Indian Ocean .................................................................................................................... 54 2.1.6 North-East Atlantic ........................................................................................................... 55 2.1.7 Mediterranean Sea ........................................................................................................... 56 2.1.8 European Union ............................................................................................................... 56 2.1.9 The Area ........................................................................................................................... 57 2.1.10 Recommendations ........................................................................................................... 62 2.2 Progress towards the Protection of Marine Biodiversity in Areas Beyond National Jurisdiction ............................................................................................................................ 63 2.2.1 Introduction ..................................................................................................................... 63 2.2.2 The challenge of effective biodiversity conservation ...................................................... 64 2.2.3 The way forward for the High Seas .................................................................................. 65 2.2.4 Contribution of the ISA..................................................................................................... 66 2.2.5 Outlook ............................................................................................................................. 68 2.2.6 Recommendations ........................................................................................................... 68 2.3 The known, the unknown, and the unknowable about the deep ocean ecology ................ 70 2.3.1 Introduction ..................................................................................................................... 70 5 Ökologische Leitplanken

  • Prionace Glauca) Across Their Life History
    Movements of Blue Sharks (Prionace glauca) across Their Life History Frederic Vandeperre1,2*, Alexandre Aires-da-Silva3, Jorge Fontes1,2, Marco Santos1,2, Ricardo Serra˜o Santos1,2, Pedro Afonso1,2 1 Centre of IMAR of the University of the Azores; Department of Oceanography and Fisheries, Horta, Portugal, 2 LARSyS Associated Laboratory, Lisboa, Portugal, 3 Inter- American Tropical Tuna Commission, La Jolla, California, United States of America Abstract Spatial structuring and segregation by sex and size is considered to be an intrinsic attribute of shark populations. These spatial patterns remain poorly understood, particularly for oceanic species such as blue shark (Prionace glauca), despite its importance for the management and conservation of this highly migratory species. This study presents the results of a long- term electronic tagging experiment to investigate the migratory patterns of blue shark, to elucidate how these patterns change across its life history and to assess the existence of a nursery area in the central North Atlantic. Blue sharks belonging to different life stages (n = 34) were tracked for periods up to 952 days during which they moved extensively (up to an estimated 28.139 km), occupying large parts of the oceanic basin. Notwithstanding a large individual variability, there were pronounced differences in movements and space use across the species’ life history. The study provides strong evidence for the existence of a discrete central North Atlantic nursery, where juveniles can reside for up to at least 2 years. In contrast with previously described nurseries of coastal and semi-pelagic sharks, this oceanic nursery is comparatively vast and open suggesting that shelter from predators is not its main function.

  • Deep-Sea Life Issue 8, November 2016 Cruise News Going Deep: Deepwater Exploration of the Marianas by the Okeanos Explorer
    Deep-Sea Life Issue 8, November 2016 Welcome to the eighth edition of Deep-Sea Life: an informal publication about current affairs in the world of deep-sea biology. Once again we have a wealth of contributions from our fellow colleagues to enjoy concerning their current projects, news, meetings, cruises, new publications and so on. The cruise news section is particularly well-endowed this issue which is wonderful to see, with voyages of exploration from four of our five oceans from the Arctic, spanning north east, west, mid and south Atlantic, the north-west Pacific, and the Indian Ocean. Just imagine when all those data are in OBIS via the new deep-sea node…! (see page 24 for more information on this). The photo of the issue makes me smile. Angelika Brandt from the University of Hamburg, has been at sea once more with her happy-looking team! And no wonder they look so pleased with themselves; they have collected a wonderful array of life from one of the very deepest areas of our ocean in order to figure out more about the distribution of these abyssal organisms, and the factors that may limit their distribution within this region. Read more about the mission and their goals on page 5. I always appreciate feedback regarding any aspect of the publication, so that it may be improved as we go forward. Please circulate to your colleagues and students who may have an interest in life in the deep, and have them contact me if they wish to be placed on the mailing list for this publication.

  • Oceanic Carbon and Water Masses During the Mystery Interval: a Model-Data Comparison Study W
    PALEOCEANOGRAPHY, VOL. 27, PA4206, doi:10.1029/2012PA002368, 2012 Oceanic carbon and water masses during the Mystery Interval: A model-data comparison study W. N. Huiskamp1 and K. J. Meissner1 Received 27 June 2012; revised 27 September 2012; accepted 2 October 2012; published 14 November 2012. [1] The ‘Mystery Interval’ (17.5–14.5 ka BP) is characterized by a large decline in 14 atmospheric D C synchronous with an increase in atmospheric CO2. The most widely accepted hypothesis to explain these observed shifts involves the existence of an isolated ‘old’ ocean carbon reservoir that was subsequently ventilated. Here we use the UVic Earth System Climate Model to locate a potential carbon rich and D14C depleted water mass under 17.5 ka BP boundary conditions. We then investigate two mechanisms for the potential ventilation of such a reservoir, namely the weakening of the North Atlantic Meridional Overturning due to iceberg calving and latitudinal shifts in Southern Hemisphere Westerlies (SHW) due to southern hemispheric warming. We find that simulations derived from an equilibrium state forced with present-day SHW and moderate North Atlantic Deep Water (NADW) formation are in better agreement with atmospheric and ocean D14C reconstructions than simulations derived from an equilibrium state forced with a northward shifted SHW belt resulting in a shut-down of the Atlantic Meridional Overturning and formation of North Pacific Deep Water. For simulations with present-day SHW, the oldest water masses are found in the North Pacific, although the Southern Ocean cannot be ruled out as a potential ‘Mystery Reservoir’. According to our simulations, the strength of Atlantic overturning is the dominant mechanism in increasing the ocean-atmosphere carbon flux, while shifting SHW results in a rearrangement of deep ocean carbon largely between the Atlantic and Pacific basins.
