Fronts in the World Ocean's Large Marine Ecosystems. ICES CM 2007
- 1 - This paper can be freely cited without prior reference to the authors International Council ICES CM 2007/D:21 for the Exploration Theme Session D: Comparative Marine Ecosystem of the Sea (ICES) Structure and Function: Descriptors and Characteristics Fronts in the World Ocean’s Large Marine Ecosystems Igor M. Belkin and Peter C. Cornillon Abstract. Oceanic fronts shape marine ecosystems; therefore front mapping and characterization is one of the most important aspects of physical oceanography. Here we report on the first effort to map and describe all major fronts in the World Ocean’s Large Marine Ecosystems (LMEs). Apart from a geographical review, these fronts are classified according to their origin and physical mechanisms that maintain them. This first-ever zero-order pattern of the LME fronts is based on a unique global frontal data base assembled at the University of Rhode Island. Thermal fronts were automatically derived from 12 years (1985-1996) of twice-daily satellite 9-km resolution global AVHRR SST fields with the Cayula-Cornillon front detection algorithm. These frontal maps serve as guidance in using hydrographic data to explore subsurface thermohaline fronts, whose surface thermal signatures have been mapped from space. Our most recent study of chlorophyll fronts in the Northwest Atlantic from high-resolution 1-km data (Belkin and O’Reilly, 2007) revealed a close spatial association between chlorophyll fronts and SST fronts, suggesting causative links between these two types of fronts.

An Assessment of Sea Scallop Abundance and Distribution in the Georges Bank Closed Area II - Preliminary Results
An Assessment of Sea Scallop Abundance and Distribution in the Georges Bank Closed Area II - Preliminary Results Submitted to: Sea Scallop Plan Development Team Falmouth, Massachusetts William D. DuPaul David B. Rudders Virginia Institute of Marine Science College of William and Mary Gloucester Point, VA 23062 VIMS Marine Resource Report No. 2007-3 June 27, 2007 Draft document-for Scallop PDT use only Do not circulate, copy or cite Project Summary As the spatial and temporal dynamics of marine ecosystems have recently become better understood, the concept of entirely closing or limiting activities in certain areas has gained support as a method to conserve and enhance marine resources. In the last decade, the sea scallop resource has benefited from measures that have closed specific areas to fishing effort. As a result of closures on both Georges Bank and in the mid-Atlantic region, biomass of scallops in those areas has expanded. As the time approaches for the fishery to harvest scallops from the closed areas, quality, timely and detailed stock assessment information is required for managers to make informed decisions about the re-opening. During May of 2007, an experimental cruise was conducted aboard the F/V Celtic, a commercial sea scallop vessel. At pre-determined sampling stations within the exemption area of Georges Bank Closed Area II (GBCAII) both a standard NMFS survey dredge and a commercial New Bedford style dredge were simultaneously towed. From the cruise, fine scale survey data was used to assess scallop abundance and distribution in the closed areas. The results of this study will provide additional information in support of upcoming openings of closed areas within the context of continuing sea scallop industry access to the groundfish closed areas on Georges Bank. -
Physiological Effects and Biotransformation of Paralytic
PHYSIOLOGICAL EFFECTS AND BIOTRANSFORMATION OF PARALYTIC SHELLFISH TOXINS IN NEW ZEALAND MARINE BIVALVES ______________________________________________________________ A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy in Environmental Sciences in the University of Canterbury by Andrea M. Contreras 2010 Abstract Although there are no authenticated records of human illness due to PSP in New Zealand, nationwide phytoplankton and shellfish toxicity monitoring programmes have revealed that the incidence of PSP contamination and the occurrence of the toxic Alexandrium species are more common than previously realised (Mackenzie et al., 2004). A full understanding of the mechanism of uptake, accumulation and toxin dynamics of bivalves feeding on toxic algae is fundamental for improving future regulations in the shellfish toxicity monitoring program across the country. This thesis examines the effects of toxic dinoflagellates and PSP toxins on the physiology and behaviour of bivalve molluscs. This focus arose because these aspects have not been widely studied before in New Zealand. The basic hypothesis tested was that bivalve molluscs differ in their ability to metabolise PSP toxins produced by Alexandrium tamarense and are able to transform toxins and may have special mechanisms to avoid toxin uptake. To test this hypothesis, different physiological/behavioural experiments and quantification of PSP toxins in bivalves tissues were carried out on mussels ( Perna canaliculus ), clams ( Paphies donacina and Dosinia anus ), scallops ( Pecten novaezelandiae ) and oysters ( Ostrea chilensis ) from the South Island of New Zealand. Measurements of clearance rate were used to test the sensitivity of the bivalves to PSP toxins. Other studies that involved intoxication and detoxification periods were carried out on three species of bivalves ( P. -

Sclerochronological Records of Arctica Islandica from the Inner German Bight Vale´Rie M
The Holocene 16,5 (2006) pp. 763Á 769 Sclerochronological records of Arctica islandica from the inner German Bight Vale´rie M. Epple´,1* Thomas Brey,2 Rob Witbaard,3 Henning Kuhnert4 and Ju¨rgen Pa¨tzold1,4 (1Research Center for Ocean Margins (RCOM), P.O. Box 330440, 28334 Bremen, Germany; 2Alfred Wegener Institute for Polar- and Marine Research, Bremerhaven, Germany; 3Netherlands Institute for Sea Research, Texel, The Netherlands; 4Department of Geosciences, University of Bremen, Bremen, Germany) Received 12 July 2004; revised manuscript accepted 16 December 2005 Abstract: Sclerochronological records of interannual shell growth variability were established for eight modern shells (26 to 163 years of age) of the bivalve Arctica islandica, which were sampled at one site in the inner German Bight. The records indicate generally low synchrony between individuals. Spectral analysis of the whole 163-yr masterchronology indicated a cyclic pattern with a period of 5 and 7 years. The masterchronology correlated poorly to time series of environmental parameters over the last 90 years. High environmental variability in time and space of the dynamic and complex German Bight hydrographic system results in an extraordinarily high ‘noise’ level in the shell growth pattern of Arctica islandica. Key words: Arctica islandica, German Bight, sclerochronology, time series, environmental variability, spectral analysis, masterchronology.

Early Ontogeny of Jurassic Bakevelliids and Their Bearing on Bivalve Evolution
Early ontogeny of Jurassic bakevelliids and their bearing on bivalve evolution NIKOLAUS MALCHUS Malchus, N. 2004. Early ontogeny of Jurassic bakevelliids and their bearing on bivalve evolution. Acta Palaeontologica Polonica 49 (1): 85–110. Larval and earliest postlarval shells of Jurassic Bakevelliidae are described for the first time and some complementary data are given concerning larval shells of oysters and pinnids. Two new larval shell characters, a posterodorsal outlet and shell septum are described. The outlet is homologous to the posterodorsal notch of oysters and posterodorsal ridge of arcoids. It probably reflects the presence of the soft anatomical character post−anal tuft, which, among Pteriomorphia, was only known from oysters. A shell septum was so far only known from Cassianellidae, Lithiotidae, and the bakevelliid Kobayashites. A review of early ontogenetic shell characters strongly suggests a basal dichotomy within the Pterio− morphia separating taxa with opisthogyrate larval shells, such as most (or all?) Praecardioida, Pinnoida, Pterioida (Bakevelliidae, Cassianellidae, all living Pterioidea), and Ostreoida from all other groups. The Pinnidae appear to be closely related to the Pterioida, and the Bakevelliidae belong to the stem line of the Cassianellidae, Lithiotidae, Pterioidea, and Ostreoidea. The latter two superfamilies comprise a well constrained clade. These interpretations are con− sistent with recent phylogenetic hypotheses based on palaeontological and genetic (18S and 28S mtDNA) data. A more detailed phylogeny is hampered by the fact that many larval shell characters are rather ancient plesiomorphies. Key words: Bivalvia, Pteriomorphia, Bakevelliidae, larval shell, ontogeny, phylogeny.
