ISOBAY 13. Santander, SPAIN. 11–13 April 2012 XIII International Symposium on Oceanography of the Bay of Biscay. ISOBAY 13. Santander, SPAIN. 11–13 April 2012 WELCOME TO ISOBAY 13 The Bay of Biscay is an area of the Atlantic Ocean enclosed by the Galician coast (NW Spain) and the Brittany coast (N France), with an extension almost half of the Iberian Peninsula and with a high proportion of the Spanish and French population living within less than 60 km from its coasts. As in all fields of the marine environment, it is subject to human pressures such as chronic pollution or accidental caused by maritime disasters, overfishing, alteration of marine habitats and the irrefutable consequences of climate change. However, from Brest to Vigo there is a large number of scientific institutions and organizations, distributed along this geographical environment, which are exploring and studying different aspects of its oceanographic phenomena: physical, chemical and biological, its flora and fauna, their ecosystems and resources. In summary this scientific potential allows to keep on investigating in all these disciplines for a better management of the functioning of coastal and deep water ecosystems in the Bay of Biscay. In order to link all the multidisciplinary studies that come out from these research Centers, the International Symposium on Oceanography of the Bay of Biscay, ISOBAY, began 25 years ago in the University of Oviedo, and since then with a periodicity "biannual" has made this event 12 times (until 2010). Each time in one of the populations of the Bay of Biscay, on the Spanish side and in the French side, in such a way that the edition of the Congress is changing alternatively. Between 11 and 13 April 2012 the 13th ISOBAY edition will take place in Santander, organized by the Spanish Institute of Oceanography of Santander (IEO), with the collaboration of the Cantabrian University (UC), the Foundation of the Environmental Hydraulics Institute of Cantabria (IH) and the Cantabrian Maritime Museum (MMC). In these conferences one of the main objectives is to highlight the progress made in the various disciplines of Oceanography in the Bay of Biscay, which benefits the debate between scientists and allows to give a global picture of the state of the marine ecosystem in this geographical area. As an example of how the scientific advances are incorporated, the main subject of the recent International Simposia of the Bay of Biscay has been shifting following the approach of marine science progress: ISOBAY 9 (Vigo 2002): Movement and transport: Prestige; ISOBAY 10 (Pau 2004): Assessment of the impacts on ecosystems; ISOBAY11 (San Sebastián 2006): Management of the biodiversity; ISOBAY12: (Brest 2012): Global changes (climate change). The main subject on this edition of ISOBAY13 will be "The conservation and sustainability of marine resources in the Bay of Biscay", since from now on it is more necessary to manage the ecosystem following the ecosystem approach. The scientific program of the symposium will include the following topics: 1) Geology, sedimentation and erosion; 2) Physical oceanography; 3) Dynamics of nutrients and plankton; 4) Biological diversity and ecosystems; 5) Fisheres and aquaculture; and 6) Anthropogenic impacts: pollution, biological indicators, environmental changes. We would like to point out that we have contacted the International Journal ISI "Deep Sea Research II" which has accepted, without any cost, to publish a special issue with the best manuscripts presented at the Symposium.

This document was designed as a tool for assessing and guiding water management in Spain. Although Spain’s future water policy is outlined in the conclusions, the points mentioned refer only to quantitative aspects of water resources without considering the issue of quality. Nonetheless, the issue of river, reservoir, lake and groundwater pollution is taken into account in the assessment section. Amongst the problems related to water quality, the White Paper notes, among others, problems related with Directives 91/271/EEC and 91/676/EEC. A brief summary of the main issues addressed is provided below. Surface water and diffuse pollution. In general, diffuse pollution produced by agricultural and livestock raising activities (e.g.

  • Checklists of Crustacea Decapoda from the Canary and Cape Verde Islands, with an Assessment of Macaronesian and Cape Verde Biogeographic Marine Ecoregions

GONZÁLEZ University of Las Palmas de Gran Canaria, i-UNAT, Campus de Tafira, 35017 Las Palmas de Gran Canaria, Spain. E-mail: [email protected]. ORCID iD: 0000-0001-8584-6731. Abstract The complete list of Canarian marine decapods (last update by González & Quiles 2003, popular book) currently com- prises 374 species/subspecies, grouped in 198 genera and 82 families; whereas the Cape Verdean marine decapods (now fully listed for the first time) are represented by 343 species/subspecies with 201 genera and 80 families. Due to changing environmental conditions, in the last decades many subtropical/tropical taxa have reached the coasts of the Canary Islands. Comparing the carcinofaunal composition and their biogeographic components between the Canary and Cape Verde ar- chipelagos would aid in: validating the appropriateness in separating both archipelagos into different ecoregions (Spalding et al. 2007), and understanding faunal movements between areas of benthic habitat. The consistency of both ecoregions is here compared and validated by assembling their decapod crustacean checklists, analysing their taxa composition, gath- ering their bathymetric data, and comparing their biogeographic patterns. Four main evidences (i.e. different taxa; diver- gent taxa composition; different composition of biogeographic patterns; different endemicity rates) support that separation, especially in coastal benthic decapods; and these parametres combined would be used as a valuable tool at comparing biotas from oceanic archipelagos.

    Lab 8: Arthropoda OEB 51 Lab 8: Arthropoda 6 April 2016 ATTENTION: Today we will be examining several preserved specimens from along the arthropod diversity and some exciting live specimens that you have not seen in the fieldtrip! Please keep all preserved specimens submerged. Examine using forceps and probes – be careful not to damage or remove the limbs of any specimen. And remember to return the specimen to its original spot in the lateral bench so your friends can find the animals properly labeled. • For each specimen, even when specific instructions are not given, make detailed observations and drawings and take notes on important characters in the evolution of arthropods, such as tagmata and adaptations to the specific environment where the organism lives. 1 Lab 8: Arthropoda OEB 51 Myriapoda With these living myriapods, take the opportunity to make a few notes on behavior – locomotory, hygienic (they frequently clean their antennae). CHOOSE ONE • Chilopoda (live) Do not handle these centipedes directly, as they are venomous (not deadly, but still). Watch these animals move, but don’t let them escape! Try to draw if you can. Compare to the large, preserved Scolopendra gigantea (MCZ specimen). Draw from the preserved for more morphological details. • Diplopoda (live) Contrary to centipedes, millipedes are docile (but they have deterrent substances, like cyanide compounds, which you might be able to smell after handling the specimens). Observe their movement. Make a sketch of the whole body and drawings of specific parts in more detail. • What is the most conspicuous difference between these two groups of myriapods? 2 Lab 8: Arthropoda OEB 51 Pycnogonida • Colossendeis colossea (Museum specimens, handle with care) • What characteristics of pycnogonids are not found in other arthropods? 3 Lab 8: Arthropoda OEB 51 Chelicerata • Xiphosura – Limulus (horseshoe crab).

Wilson1, J. Zhang3,15 and N. J. Bax2,16 Abstract Background: Our knowledge of the benthic fauna at lower bathyal to abyssal (LBA, > 2000 m) depths off Eastern Australia was very limited with only a few samples having been collected from these habitats over the last 150 years. In May–June 2017, the IN2017_V03 expedition of the RV Investigator sampled LBA benthic communities along the lower slope and abyss of Australia’s eastern margin from off mid-Tasmania (42°S) to the Coral Sea (23°S), with particular emphasis on describing and analysing patterns of biodiversity that occur within a newly declared network of offshore marine parks. Methods: The study design was to deploy a 4 m (metal) beam trawl and Brenke sled to collect samples on soft sediment substrata at the target seafloor depths of 2500 and 4000 m at every 1.5 degrees of latitude along the western boundary of the Tasman Sea from 42° to 23°S, traversing seven Australian Marine Parks.
