ENSO across eastern tropical Pacific
Weekly averaged sea surface temperatures (top, °C) and anomalies (bottom, °C) for the past twelve weeks. SST analysis is the optimum interpolation (OI) analysis, while anomalies are departures from the adjusted OI climatology (Reynolds and Smith 1995, J. Climate, 8, 1571-1583).

Cirratulidae & Spionidae Identification Workshop 26th to 28th November 2010 in Bath
This course will enable participants to gain experience and develop confidence in the identification of species of Spionidae and Cirratulidae, two common families of marine annelids. The course will include an introductory talk on each of the groups covering body parts, terminology and use of the important dichotomous keys for each group. The main focus of the weekend will be microscope work, allowing students to work through specimens from the two families at their own speed. Participants will carry out identification using industry standard keys and papers with the assistance of two professional marine biologists who between them have over fifteen years experience of processing benthic samples. Specimens from the majority of British genera will be available. Time will be allocated at the end of the course for participants to look at their own specimens with assistance from the course leaders.
Course fees include membership to the Marine Biological Association of the UK. Existing members of the Marine Biological Association are entitled to a 10% discount on the rate.

Introduction to Benthic Taxonomy
A two week course to be held at the Marine Biological Association in Plymouth. This course is aimed at undergraduates and recent graduates wishing to develop their benthic identification skills. The course will ;
* introduce students to the concepts and uses of benthic taxonomy
* provide experience of both intertidal and subtidal sample collection, preservation and analysis
* provide training in the use and construction of dichotomous keys (including online resources)
* develop taxonomic understanding and exposure
Specialist Taxonomy Short Courses
Short courses concentrating on particular phyla, families or interest groups. These courses are aimed at graduates and practising taxonomists wishing to enhance their knowledge of marine taxonomy. Demonstrable experience in marine taxonomy or completion of the Introduction to Marine Taxonomy is a prerequisite to these courses. You will only be awarded a place on a particular course if we are happy that you have the required prior knowledge.

Vacancy: Senior Marine Macrobenthic Taxonomist
(From Annelida group)
Dear Colleagues,
We have the following vacancy at Marine Ecological Surveys Ltd (MESL).
Deadline for applications has already expired, but we would be happy to consider further applications until the 15th of September 2010.
Kind regards,
Sara Marzialetti
Vacancy: Senior Marine Macrobenthic Taxonomist
The MESL laboratory specialises in analysis of benthic and epibenthic samples from a wide variety of environments ranging from estuarine to offshore. Primarily our work consists of monitoring for the aggregate industry and, more recently, the renewable energy sector. Our staff comprise of an experienced team of marine biologists who are self-motivated and work to tight deadlines.
We are looking for a senior marine macrobenthic taxonomist whose primary role will be to undertake analysis of benthic samples and identification of all taxonomic groups, together with training of junior staff in benthic taxonomy. You will be educated to at least degree level in marine biology or a related discipline and also have at least two years experience in marine invertebrate analysis and taxonomic identification. While you will be mostly lab-based, you will also be required to participate in fieldwork.
MESL participates in the NMBAQC scheme, and in conjunction with this, we run our own internal training scheme to develop the taxonomic skills of our laboratory staff. We also encourage continued professional development for all our staff.
Please email your CV to lab@seasurvey.co.uk

Identity of epibiotic bacteria on symbiontid euglenozoans in O2-depleted marine sediments: evidence for symbiont and host co-evolution
V P Edgcomb, S A Breglia, N Yubuki, D Beaudoin, D J Patterson, B S Leander and J M Bernhard
Abstract
A distinct subgroup of euglenozoans, referred to as the ‘Symbiontida,’ has been described from oxygen-depleted and sulfidic marine environments. By definition, all members of this group carry epibionts that are intimately associated with underlying mitochondrion-derived organelles beneath the surface of the hosts. We have used molecular phylogenetic and ultrastructural evidence to identify the rod-shaped epibionts of the two members of this group, Calkinsia aureus and B.bacati, hand-picked from the sediments of two separate oxygen-depleted, sulfidic environments. We identify their epibionts as closely related sulfur or sulfide-oxidizing members of the epsilon proteobacteria. The epsilon proteobacteria generally have a significant role in deep-sea habitats as primary colonizers, primary producers and/or in symbiotic associations. The epibionts likely fulfill a role in detoxifying the immediate surrounding environment for these two different hosts. The nearly identical rod-shaped epibionts on these two symbiontid hosts provides evidence for a co-evolutionary history between these two sets of partners. This hypothesis is supported by congruent tree topologies inferred from 18S and 16S rDNA from the hosts and bacterial epibionts, respectively. The eukaryotic hosts likely serve as a motile substrate that delivers the epibionts to the ideal locations with respect to the oxic/anoxic interface, whereby their growth rates can be maximized, perhaps also allowing the host to cultivate a food source. Because symbiontid isolates and additional small subunit rDNA gene sequences from this clade have now been recovered from many locations worldwide, the Symbiontida are likely more widespread and diverse than presently known.

Meiofauna reduces bacterial mineralization of naphthalene in marine sediment
Johan Näslund, Francisco JA Nascimento and Jonas S Gunnarsson
Abstract
The role of sediment-living meiofauna, benthic invertebrates smaller than 1000 μm such as nematodes and ostracods, on the mineralization of naphthalene, a common polycyclic aromatic hydrocarbon (PAH) in marine sediments, was studied in microcosms using radiorespirometry. A method to extract live meiofauna was developed and used in order to experimentally manipulate meiofauna abundance and group diversity. Higher abundances of meiofauna were found to significantly decrease naphthalene mineralization. Furthermore, a change in the bacterial community composition (studied using terminal restriction fragment length polymorphism) was also observed in presence of higher meiofauna abundance, as well as a lower number of cultivable naphthalene-degrading bacteria. The reduced mineralization of naphthalene and the altered bacterial community composition in the presence of increased meiofauna abundance is likely the result of top-down control by meiofauna. This study shows that higher abundances of meiofauna can significantly decrease the microbial mineralization of PAHs such as naphthalene and also significantly modify the bacterial community composition in natural marine sediments.
