Opis:
Synthesis and New Conception of North Sea Research (SYCON) is the title of a German project carried out from 1998–2000 under the leadership of Hamburg University1. It was accompanied by an international advisory board and covered North Sea issues as well as the general challenges to shelf sea research and sustainable management under global change. Particular emphasis was placed on the interdisciplinary analysis of comprehensive areas of knowledge: the data situation, understanding of processes, model development, instruments and methods, understanding of the system. Based on this, perspectives for future North Sea research were developed. The project produced a synthesis report, eleven monodisciplinary reports and an illustrated brochure for the general public (see Annex 1, this paper, p. 258).

Opis:
This paper presents the results of a Secchi depth data mining study for the North Sea – Baltic Sea region. 40,829 measurements of Secchi depth were compiled from the area as a result of this study. 4.3% of the observations were found in the international data centers [ICES Oceanographic Data Center in Denmark and the World Ocean Data Center A (WDC–A) in the USA], while 95.7% of the data was provided by individuals and ocean research institutions from the surrounding North Sea and Baltic Sea countries. Inquiries made at the World Ocean Data Center B (WDC–B) in Russia suggested that there could be significant additional holdings in that archive but, unfortunately, no data could be made available. The earliest Secchi depth measurement retrieved in this study dates back to 1902 for the Baltic Sea, while the bulk of the measurements were gathered after 1970. The spatial distribution of Secchi depth measurements in the North Sea is very uneven with surprisingly large sampling gaps in the Western North Sea. Quarterly and annual Secchi depth maps with a 0.5◦×0.5◦ spatial resolution are provided for the transition area between the North Sea and the Baltic Sea (4◦E–16◦E, 53◦N–60◦N).

Opis:
Although the fossil record of beaked whales (Cetacea, Odontoceti, Ziphiidae) is continuously improving, the geological age of new taxa is often poorly constrained. Based on a partial cranium from deep seafloor deposits off Galicia, Spain, we describe a new species of the stem beaked whale genus Beneziphius, B. cetariensis sp. nov. The latter differs from the type species B. brevirostris in the larger size, the rostrum being proportionally longer, the premaxillae being longer than the maxillae at the apex of the rostrum, the left premaxillary sac fossa being transversely concave, and the ascending process of the premaxilla reaching the vertical. Considering that the stratigraphic context of deep-sea deposits off the Iberian Peninsula is not precisely known, we provisionally propose an extended, middle Miocene to early Pliocene interval for the geological age of B. cetariensis. Nonetheless, the palynological analysis of sediment sampled from cavities in the cranium of the holotype of B. brevirostris, discovered during the second part of the nineteenth century in inland deposits of Antwerp (north of Belgium), yield an early to mid-Serravallian age (13.2–12.8 Ma, late middle Miocene). B. brevirostris is thus the oldest described species of the “Messapicetus clade”, a large clade of stem ziphiids in which most species are dated from the late Miocene. The description of the Galician species B. cetariensis broadens the biogeographic distribution of Beneziphius and confirms the strong ziphiid faunal affinities between the eastern coast of the North Atlantic and the southern margin of the North Sea Basin.

Opis:
There is growing focus on multi-functional use of the marine environment. The solution presented is to combine different economic activities in ‘multi-use platforms at sea’ (MUPS). An expanding body of literature focusses on the economic, technical or social challenges that follow from combining these different functions at sea. Current Dutch policy sees MUPS as a promising way to make the most out of scarce space available but present rules and regulations not supportive of MUPS. To find the right mode of governance for developing MUPS one needs a discourse coalition with a shared definition of (1) the problem tackled, (2) the solution it brings, (3) the solutions envisioned (including design and user functions) and (4) the role of various actors in bringing about these solutions. In this article we present a discourse analysis of the North Sea on the governance of MUPS. It shows that there is no single shared discourse but that there are contesting views on what MUPS are or should be. Although some convergence of discourse takes place, the question whose problem is solved by MUPS remains unanswered: do they solve public problems such as nature conservation and spatial planning or are MUPS the solution to high Operation and Maintenance costs? This hampers the development of multi-use platforms at sea with neither public nor private actors willing to take the lead.

Opis:
Although modern porpoises (Phocoenidae, Odontoceti, Cetacea) occupy most oceanic regions of the world, their fossil record outside the Pacific Ocean remains extremely scarce. Based on a partial skull from lower Pliocene layers (Kattendijk Formation, Zanclean, 5–4.4 Ma) of the Antwerp harbour, a new genus and species of fossil phocoenid, Brabocetus gigaseorum gen. et sp. nov., is described. The new taxon is diagnosed by a unique combination of characters including an anterolateraly widely-open antorbital notch, the anteromedial sulcus being shorter than the posteromedial sulcus, the frontal boss being longer than wide, pronounced asymmetry of the vertex, and the possible presence of an additional longitudinal sulcus across the premaxillary eminence. The phylogenetic analysis indicates that B. gigaseorum is not closely related to extant phocoenids; it is included in a clade comprising most north-west Pacific fossil species, two north-east Pacific fossil species, and the only previously described North Sea fossil species Septemtriocetus bosselaersi. Considering the paleobiogeographic distribution of phocoenids, an early Pliocene arrival from the North Pacific to the North Sea may be correlated to the early opening of the Bering Strait and migration via the Arctic. The presence of S. bosselaersi in younger deposits (Piacenzian) of the southern margin of the North Sea Basin could be the result of either a second dispersal event, or of local speciation in the North Sea, whereas an additional trans-Arctic migration from the North Pacific lead to the present occupation of the North Atlantic and North Sea by the phylogenetically distantly related harbor porpoise Phocoena phocoena.

Opis:
The investigation of the Late Paleogene to Late Neogene species of rissoid gastropod Galeodinopsis in the Euro-Mediterranean area has supported the hypothesis that this genus is an intermediate form between two well-known rissoids, Alvinia and Manzonia. We recognized four species of Galeodinopsis: G. biangulata, G. germanica sp. nov., G. semperi (new name for Rissoa duboisii), and G. tiberiana. The oldest (very Late Eocene/Oligocene) representatives of Galeodinopsis, G. biangulata, and G. semperi, share similar shell shape and microsculpture with Alvinia. This suggests that Galeodinopsis originated from some Eocene species related to Alvinia. The new species represents the first occurrence within Galeodinopsis of a combination of characters very close to those of Manzonia, above all the typical pitted microsculpture. We hypothesize that Manzonia evolved from Galeodinopsis rather than from the genera Alvania or Alvinia, as previously supposed. Galeodinopsis originated during the very Late Eocene/Oligocene in the North Sea Basin. Afterwards it underwent a strong southward shift to the mid-high east Atlantic and the Mediterranean area, during the Mio-Pliocene, and to the Recent tropical eastern Atlantic coasts, where the type species G. tiberiana still lives. The shift likely was due to a combination of climate cooling and palaeogeographical changes. The distribution of G. biangulata suggests that connections between the North Sea Basin and the Atlantic domain opened through the Channel area at least during the Early Oligocene, earlier than indicated previously. The distribution of Manzonia moulinsi supports the idea of a southern connection to the Atlantic Aquitaine Basin via the Rhine Graben during the Late Oligocene. From a palaeoecological point of view, Galeodinopsis includes warm species with planktotrophic larval development that are typical of the shelf environment in fully marine conditions.

Opis:
A GIS (Geographical Information System) based study on deposition in the North Sea – Baltic Sea transition area has been carried out. The study is based on (i) a digital bathymetry model, (ii) 93 available 210Pb/137Cs sedimentation rate estimations, (iii) grain-size distributions, organic matter, C, N and P content of 64 top 1 cm sediment samples from the study area, and (iv) GIS-based modelling of resuspension potentials based on wind statistics. With the use of regression statistics on depth, resuspension potential and sediment characteristics, results are extrapolated area-wide from the 64 sampling positions. The area is divided into sediment types and classified as accumulation or erosion/transport bottoms. Model results show good agreement with existing maps of sediment distributions, indicating that the sediment distribution is governed to a large extent by windinduced waves. Correlations of sediment types, their deposition rates and their N and P contents were used to estimate spatial deposition rates. In all, the yearly deposition in the study area amounts to 2.8 million tons of organic matter, 0.14 million tons of total nitrogen, and 0.035 million tons of total phosphorus. Correlations of sediment types and dry bulk densities were used to infer spatial inventories of organic matter and total nitrogen and phosphorus in the top 1 cm of the sediments. A total of 100 million tons of organic matter, 4 million tons of total nitrogen, and 0.019 million tons of total phosphorus are contained in the top 1 cm of the sediments in the study area. In general, the deep parts of the study area with low resuspension potentials act as sinks for the fine-grained sediments and their associated particulate nutrients.
