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.

The Valorisation of Sargassum from Beach Inundations
Journal of Marine Science and Engineering Review Golden Tides: Problem or Golden Opportunity? The Valorisation of Sargassum from Beach Inundations John J. Milledge * and Patricia J. Harvey Algae Biotechnology Research Group, School of Science, University of Greenwich, Central Avenue, Chatham Maritime, Kent ME4 4TB, UK; [email protected] * Correspondence: [email protected]; Tel.: +44-0208-331-8871 Academic Editor: Magnus Wahlberg Received: 12 August 2016; Accepted: 7 September 2016; Published: 13 September 2016 Abstract: In recent years there have been massive inundations of pelagic Sargassum, known as golden tides, on the beaches of the Caribbean, Gulf of Mexico, and West Africa, causing considerable damage to the local economy and environment. Commercial exploration of this biomass for food, fuel, and pharmaceutical products could fund clean-up and offset the economic impact of these golden tides. This paper reviews the potential uses and obstacles for exploitation of pelagic Sargassum. Although Sargassum has considerable potential as a source of biochemicals, feed, food, fertiliser, and fuel, variable and undefined composition together with the possible presence of marine pollutants may make golden tides unsuitable for food, nutraceuticals, and pharmaceuticals and limit their use in feed and fertilisers. Discontinuous and unreliable supply of Sargassum also presents considerable challenges. Low-cost methods of preservation such as solar drying and ensiling may address the problem of discontinuity. The use of processes that can handle a variety of biological and waste feedstocks in addition to Sargassum is a solution to unreliable supply, and anaerobic digestion for the production of biogas is one such process. -

It can accumulate high biomass and may quickly become a strong competitor for space and light. Dense Sargassum muticum stands may reduce light, decrease flow, increase sedimentation and reduce ambient nutrient concentrations available for native kelp species. Sargassum muticum has also become a major nuisance in recreational waters. view this species on IUCN Red List Species Description MarLIN (2003) states that, \"Sargassum muticum is a large brown seaweed (with a frond often over 1m long), the stem has regularly alternating branches with flattened oval blades and spherical gas bladders. It is highly distinctive and olive-brown in colour.\" Arenas et al. (2002) report that, \"The growth form of S. muticum is modular and approaches the structural complexity of terrestrial plants.

Engle2, Shinya Uwai3, Hiroshi Kawai3 1University Herbarium, University of California, Berkeley, California, USA 2 Marine Science Institute, University of California, Santa Barbara, California, USA 3 Research Center for Inland Seas, Kobe University, Rokkodai, Kobe 657–8501, Japan correspondence: Kathy Ann Miller e-mail: [email protected] fax: 1-510-643-5390 telephone: 510-387-8305 1 ABSTRACT We report the occurrence of the brown seaweed Sargassum filicinum Harvey in southern California. Sargassum filicinum is native to Japan and Korea. It is monoecious, a trait that increases its chance of establishment. In October 2003, Sargassum filicinum was collected in Long Beach Harbor. In April 2006, we discovered three populations of this species on the leeward west end of Santa Catalina Island. Many of the individuals were large, reproductive and senescent; a few were small, young but precociously reproductive. We compared the sequences of the mitochondrial cox3 gene for 6 individuals from the 3 sites at Catalina with 3 samples from 3 sites in the Seto Inland Sea, Japan region. The 9 sequences (469 bp in length) were identical. Sargassum filicinum may have been introduced through shipping to Long Beach; it may have spread to Catalina via pleasure boats from the mainland. Key words: California, cox3, invasive seaweed, Japan, macroalgae, Sargassum filicinum, Sargassum horneri INTRODUCTION The brown seaweed Sargassum muticum (Yendo) Fensholt, originally from northeast Asia, was first reported on the west coast of North America in the early 20th c. (Scagel 1956), reached southern California in 1970 (Setzer & Link 1971) and has become a common component of California intertidal and subtidal communities (Ambrose and Nelson 1982, Deysher and Norton 1982, Wilson 2001, Britton-Simmons 2004). -

The Mid-Atlantic Ridge Hypothesis
www.nature.com/scientificreports OPEN New clues on the Atlantic eels spawning behavior and area: the Mid‑Atlantic Ridge hypothesis Yu‑Lin K. Chang1, Eric Feunteun2*, Yasumasa Miyazawa1 & Katsumi Tsukamoto3 The Sargasso Sea has long been considered as the only spawning area for Atlantic eels, despite the absence of direct observations. The present study raises a novel scenario, deviating from Schmidt’s dogma, begins with a review of historical and recent observations that were combined to build up a global theory on spawning ecology and migration behavior of Atlantic eels. From this, it is argued that a favorable spawning area could be located eastward of Sargasso Sea at the intersection between the Mid-Atlantic Ridge and the oceanic fronts. Ocean circulation models combined with 3D particle- tracking method confrmed that spawning at this specifc area would result in larval distribution ftting the feld observation. This study explores the hypothesis that leptocephali are able to swim and orientate to reach their specifc growth areas. It proposes a novel framework about spawning ecology, based on orientation, navigation and meeting cues of silver eels to the spawning area. Together this framework may serve as a stepping‑stone for solving the long‑lasting mystery of eel reproduction which frst came out 2,400 years ago and promotes the understanding of oceanic migration and reproduction of marine organisms. Since Danish fshery biologist Johannes Schmidt’s renowned discovery in the twentieth century, the Sargasso Sea has been widely considered to be the Atlantic Ocean spawning area for the European eel Anguilla anguilla and American eel Anguilla rostrata1. -
