Description: This study sets out to assess the economic value of ocean observations in qualitative terms. The study aims to examine the perspective of selected co-developers and end users on the impact of the EuroSea Key Exploitable Results on them. While efforts were made to collect quantitative data on the economic impact of the results on the users, this report uses a focussed case study approach to qualitatively assess the value of the demonstration products and services for the co-developers and users. The report focusses on the main demonstration products and services with potential for commercialisation in EuroSea that were identified in the exploitation strategy.

Description: This document demonstrates the capability of seasonal forecasting systems to predict observable and user-relevant ocean climate indicators.

Description: This task set out to increase communication between the ocean monitoring and modelling communities in the Baltic Sea area. Through these improved communications, the goal was to advance and improve the HELCOM marine environmental assessments. To gain confidence in the numerical model outputs, an effort was undertaken to ensure ocean observing in-situ data, collected by multiple nations in the Baltic Sea, was assimilated into a numerical model. Here, we report on the development of indicators, as requested by our stakeholders, and we discuss if the Baltic Sea numerical modelling efforts are ready to augment regional environmental status reports, and can our results help guide environmental management in the region.

Description: New sedimentological data of facies and diagenesis as well as chronological data including strontium (87Sr/86Sr)-isotope ratios and uranium (U)-series dating, radiocarbon (14C) accelerator mass spectrometry (AMS) dating and biostratigraphy from elevated reef terraces (makatea) in the southern Cook Islands of Mangaia, Rarotonga and Aitutaki contribute to controversial discussions regarding age and sea-level relationships of these occurrences during the Neogene and Quaternary. The oldest limestones of the uplifted makatea island of Mangaia include reef-related facies which are mid-Miocene in age, based on new Sr-isotope and biostratigraphical data. In between these older deposits and the lowest coastal reef terrace of marine isotope stage (MIS) 5e, various older Pleistocene reef-related facies were identified. Based on Sr-isotope ratios, these were deposited during earlier Pleistocene highstands (as old as 2.28 Ma). Rare reef terraces on Rarotonga belong to the Plio-Pleistocene and the late Miocene, according to 87Sr/86Sr ratios. The late Miocene age is enigmatic as it exceeds the age of subaerially exposed volcanic rocks of Rarotonga island. The fossil reef could have formed on an older submarine volcanic high that was later displaced by younger volcanism to its present position, or the Sr-age could be too old due to diagenetic resetting. The Plio-Pleistocene Rarotonga reef terraces are overlain irregularly by Holocene reef deposits that are interpreted as storm rubble. Reef terraces on Aitutaki represent evidence of a higher-than-present (up to 1 m) sea-level during the late Holocene, based on 14C AMS age data. They are very similar to elevated late Holocene reefs of adjacent French Polynesia with regard to composition, elevation and age.

Description: The present study aims to valorize the apple peels (AP) and grape seeds (GS) by the fortification of the yogurts using their powder. Firstly, the optimization of the extraction parameters for assessing maximum of total phenolic content (TPC) was achieved. Under the optimized conditions, the experimental maximum yields of TPC were 19.33 ± 2.33 and 240.59 ± 4.77 mg Gallic Acid Equivalents (GAE)/100 g Dry Weight (DW) for AP and GS, respectively, which was in close agreement with predicted values (19.32 ± 0.91 and 242.26 ± 11.08 mg GAE/100 g DW for AP and GS, respectively). The antioxidant capacity of GS extract was better with IC50 of 12.22 ± 0.89 and 225.47 ± 7.10 µg/ml in DPPH and phosphomolybdenum assays, respectively. Besides, powder from these by-products was incorporated into yogurt samples. The classification test revealed that the yogurt prepared with GS powder was the preferred one.

Description: Rho.do.spi.ril'lum. Gr. neut. n. rhodon, the rose; N.L. neut. n. Spirillum, a bacterial genus; N.L. neut. n. Rhodospirillum, the rose Spirillum. Proteobacteria / Alphaproteobacteria / Rhodospirillales / Rhodospirillaceae / Rhodospirillum The genus Rhodospirillum has harbored a diverse set of spiral-shaped phototrophic bacteria, most of which have been reclassified as species of other genera, families, and even orders and phyla since the 1980s. The heterogeneity has been long known, but only the faith into sequence-based information gave strong support for taxonomic rearrangements. Currently, the genus Rhodospirillum contains a single species, which is characterized by spiral-shaped cells, motility by bipolar flagella, and internal membranes as vesicles. It performs anaerobic photosynthesis, which is restricted to anoxic light conditions due to the oxygen-sensitive biosynthesis of bacteriochlorophyll and thus the phototrophic apparatus. It can grow photoheterotrophically as well as photoautotrophically. The key enzyme of autotrophic carbon dioxide fixation in Rhodospirillum rubrum, ribulose bisphosphate carboxylase (RubisCO) type-II, is well characterized and forms a homodimer that is also encoded in some related genera of Rhodospirillaceae. Chemotrophic growth may also occur under microoxic to oxic conditions in the dark and anaerobically by fermentation. The genus comprises mesophilic freshwater bacteria. Ubiquinones and rhodoquinones with 10 isoprene units and fatty acids typical of other Alphaproteobacteria with C18:1, C16:0, and C16:1 as major components are present. DNA G + C content (mol%): 64.6–65.7, type 65.4 (genome analysis), 63.8–65.8 (Bd). Type species: Rhodospirillum (Rsp.) rubrum Molisch 1907AL (basonym: Spirillum rubrum Esmarch 1887).

Description: Report on assessment of the EuroSea observational (and thematic) networks coordination This Deliverable serves to present the initial situation, in terms of coordination, of the observation and thematic networks in EuroSea represented in work package 3 (WP3). The networks include the networks represented in EuroGOOS and additional ones. The study is based on a comprehensive questionnaire that was answered by all EuroSea WP3 tasks. In addition, information from the Global Observing Networks of GOOS was considered. An important basis for the questionnaire was the list of "Network Attributes, Commitment and Benefits -What it means to be an OPA network" which was compiled by the Observation coordination group (OCG) of GOOS. This deliverable is linked to the deliverable D3.10 that will repeat the assessment at the end of the EuroSea project to assess the evolution of the coordination over the period of the EuroSea project. The present study shows that the observation and thematic networks in EuroSea all have highly developed coordination mechanism elements, except for task 3.7 - ASV, which represents a new network to be established. Given the spectrum of coordination themes and envisioned targets significant heterogeneity across the networks is also evident. The coordination of ship-based observations is not fully represented in EuroSea (and thus in EuroGOOS) and ideally this task should have been divided into research vessels and commercial vessels (container ships, ferries) but as it stands currently is dominated by one technology only (Ferrybox). This reflects the situation in EuroGOOS. For the thematic networks it is interesting to note that the observatories that are operated in task 3.8 (Augmented observatories) are not represented in the observational networks (task 3.1-3.7). The assessment presented in this deliverable has its focus on the status quo. It does not question or analyze the necessity for individuals, institutions and countries to be represented in a network - “Why should individuals, institutions or countries feel a need or a motivation to engage with the networks?”. It seems logical that networks are only founded, maintained and developed when individuals see an advantage in their involvement in a network – for themselves, their institution or a country. The "characteristics" of the apparent advantage of contributing to a network is likely of central importance. For example, if the advantage is only that there are no disadvantages (e.g. fines), a further development and improvement of the network is questionable. This important investigation of the motivation of individuals will be part of final assessment prepared in D3.10.

Internal photosynthetic membranes are present as lamellae underlying and parallel to the cytoplasmic membrane. Cells are rod shaped to ovoid and exhibit polar growth, budding, and asymmetric cell division and form rosette-like cell aggregates. They are motile by means of subpolar flagella and stain Gram-negative. Straight-chain monounsaturated C18:1 is the predominant component of cellular fatty acids. Ubiquinones and menaquinones are present, and the lipopolysaccharides are characterized by a 2,3-diamino-2,3-deoxy-d-glucose (DAG)-containing, phosphate-free lipid A with amide-bound C14:0 3OH. DNA G + C content (mol%): 63.8–68.3. Type species: Blastochloris viridis (Drews and Giesbrecht 1966) Hiraishi 1997 (Rhodopseudomonas viridis Drews and Giesbrecht 1966).

Description: Rho.do.mi.cro' bi.um. Gr. neut. n. rhodon the rose; Gr. masc. adj. micros small; Gr. masc. n. bios life; N.L. neut. n. Rhodomicrobium red microbe. Proteobacteria / Alphaproteobacteria / Rhizobiales / Hyphomicrobiaceae / Rhodomicrobium Most characteristic for Rhodomicrobium species is the polar cell growth and the characteristic vegetative growth cycle which includes the formation of peritrichously flagellated swarmer cells and nonmotile “mother cells,” which form prosthecae from one to several times the length of the mother cell. Daughter cells originate as spherical buds at the end of the prosthecae and may undergo differentiation in various ways. They are Gram‐negative ovoid to elongate‐ovoid bacteria belonging to the Alphaproteobacteria. Internal photosynthetic membranes are of the lamellar type. Photosynthetic pigments are bacteriochlorophyll a and carotenoids of the spirilloxanthin series. The predominant cellular fatty acid is C18:1, which comprises more than 80% of the membrane‐bound fatty acids. Ubiquinone and rhodoquinone with 10 isoprene units are present, and the lipopolysaccharides are characterized by a glucosamine‐containing, phosphate‐free lipid A with amide‐bound C16:0 3 OH. DNA G + C content (mol%): 61.8–63.8. Type species: Rhodomicrobium vannielii Duchow and Douglas 1949.

Description: The availability of dissolved iron (dFe) exerts an important control on primary production. Recent ocean observation programs have provided information on dFe in many parts of the ocean, but knowledge is still limited concerning the rates of processes that control the concentrations and cycling of dFe in the ocean and hence the role of dFe as a determinant of global primary production. We constructed a three-dimensional gridded dataset of oceanic dFe concentrations by using both observations and a simple model of the iron cycle, and estimated the difference of processes among the ocean basins in controlling the dFe distributions. A Green's function approach was used to integrate the observations and the model. The reproduced three-dimensional dFe distribution indicated that iron influx from aeolian dust and from shelf sediment were 7.6 Gmol yr and 4.4 Gmol yr in the Atlantic Ocean and 0.4 Gmol yr and 4.1 Gmol yr in the Pacific Ocean. The residence times were estimated to be 12.2 years in the Atlantic and 80.4 years in the Pacific. These estimates imply large differences in the cycling of dFe between the two ocean basins that would need to be taken into consideration when projecting future iron biogeochemical cycling under different climate change scenarios. Although there is some uncertainty in our estimates, global estimates of iron cycle characteristics based on this approach can be expected to enhance our understanding of the material cycle and hence of the current and future rates of marine primary production.
