Deep Sea Research Part I: Oceanographic Research Papers
Clusters of deep-sea egg-brooding octopods associated with warm fluid discharge: an ill-fated fragment of a larger, discrete population? - NEW!
Anne. M. Hartwell, Janet. R. Voight, Charles Geoffrey Wheat*
*C-DEBI Contribution 419


Benthic octopods cluster on bare rock on Dorado Outcrop, a ~3000 m deep basalt exposure. The outcrop hosts intermittent discharge of relatively cool (up to 12.3 °C) hydrothermal fluid that carries about half as much oxygen as bottom seawater (~54 μM vs. 108 μM). We analyzed 231 hours of video footage and still images taken by sub-sea vehicles in 2013 and 2014 that documented the clustered octopods, members of the poorly-known genus Muusoctopus. The largest cluster (102 octopods) occurred in a 19 m2 area of fluid discharge, where the basalt was sediment-free; individual octopods were also seen across the outcrop. The clustered octopods appeared to be brooding eggs and a total of 11 egg clutches were confirmed. None of the 186 eggs closely examined showed embryonic development. The intermittent fluid discharge may clear the basalt of sediment and attract gravid octopods which then spawn. However, the increased temperature and limited oxygen of the discharging fluids may threaten the octopods’ survival. Octopods in/near areas of discharging fluid had significantly higher estimated respiration rates (3.1–9.8 contractions/minute) than did octopods away from discharging fluid (0.8–6.0 contractions/minute). Warm fluids likely increase the octopods’ metabolic rate and thus their oxygen demand but provide only limited oxygen. The resultant physiological stress is hypothesized to eventually kill eggs near fluid discharge. We hypothesize, because these eggs do not survive, the population is sustained by a larger pool of undetectable females that brood their eggs inside cool conduits of this and perhaps other, unstudied basalt outcrops.

Thioclava electrotropha sp. nov., a versatile electrode and sulfur-oxidizing bacterium from marine sediments - NEW!
Rachel Chang, Lina. J. Bird, Casey Barr, Magdalena R. Osburn, Elizabeth Wilbanks, Kenneth H. Nealson, Annette R. Rowe*
*C-DEBI Contribution 420


A taxonomic and physiologic characterization was carried out on Thioclava strain ElOx9T, which was isolated from a bacterial consortium enriched on electrodes poised at electron donating potentials. The isolate is Gram-negative, catalase-positive and oxidase-positive; the cells are motile short rods. The bacterium is facultatively anaerobic with the ability to utilize nitrate as an electron acceptor. Autotrophic growth with H2 and S0 (oxidized to sulfate) was observed. The isolate also grows heterotrophically with organic acids and sugars. Growth was observed at salinities from 0 to 10% NaCl and at temperatures from 15 to 41 °C. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain belongs in the genus Thioclava ; it had the highest sequence similarity of 98.8 % to Thioclava atlantica 13D2W-2T, followed by Thioclava dalianensis DLFJ1-1T with 98.5 % similarity, Thioclava pacifica TL 2T with 97.7 % similarity, and then Thioclava indica DT23-4T with 96.9 %. All other sequence similarities were below 97 % to characterized strains. The digital DNA–DNA hybridization estimated when compared to T. atlantica 13D2W-2T, T. dalianensis DLFJ1-1T, T. pacifica TL 2T and T. indica DT23-4T were 15.8±2.1, 16.7+2.1, 14.3±1.9 and 18.3±2.1 %. The corresponding average nucleotide identity values between these strains were determined to be 65.1, 67.8, 68.4 and 64.4 %, respectively. The G+C content of the chromosomal DNA is 63.4 mol%. Based on these results, a novel species Thioclava electrotropha sp. nov. is proposed, with the type strain ElOx9T (=DSM 103712T=ATCC TSD-100T).


Marine Technology Society Journal
Effective Strategies for Engaging Community College Students in Research via Cutting-Edge Technology - NEW!
Stephanie Schroeder*, Jan P. Amend*
*C-DEBI Contribution 421


As we train the next generation of Science, Technology, Engineering, and Math (STEM) researchers, it is imperative that we expand our recruitment to community college students. Many of these students are highly motivated and extremely talented, but they often lack exposure to cutting edge technology found at R1 institutions, much less have the opportunities to participate in original research. The Center for Dark Energy Biosphere Investigations (C-DEBI) at the University of Southern California (USC) started a community college research internship summer program in 2013. The non-residential and residential programs combined so far have trained 60 students in the biogeosciences, with 46 of them having transferred to four-year institutions and 95% remaining in STEM fields. Their introduction to and acquired competence in several advanced technologies have further prepared these students to pursue graduate degrees and rewarding careers in research-based STEM fields. 

The Marine Technology Society is a not-for-profit, international, professional association. Founded in 1963, the Society believes that the advancement of marine technology and the productive, sustainable use of the oceans depend upon the active exchange of ideas between government, industry and academia.

Marine Policy
Scientific rationale and international obligations for protection of active hydrothermal vent ecosystems from deep-sea mining - NEW!

*C-DEBI Contribution 425


There is increasing interest in mining minerals on the seabed, including seafloor massive sulfide deposits that form at hydrothermal vents. The International Seabed Authority is currently drafting a Mining Code, including environmental regulations, for polymetallic sulfides and other mineral exploitation on the seabed in the area beyond national jurisdictions. This paper summarizes 1) the ecological vulnerability of active vent ecosystems and aspects of this vulnerability that remain subject to conjecture, 2) evidence for limited mineral resource opportunity at active vents, 3) non-extractive values of active vent ecosystems, 4) precedents and international obligations for protection of hydrothermal vents, and 5) obligations of the International Seabed Authority under the UN Convention on the Law of the Sea for protection of the marine environment from the impacts of mining. Heterogeneity of active vent ecosystems makes it extremely challenging to identify “representative” systems for any regional, area-based management approach to conservation. Protection of active vent ecosystems from mining impacts (direct and indirect) would set aside only a small fraction of the international seabed and its mineral resources, would contribute to international obligations for marine conservation, would have non-extractive benefits, and would be a precautionary approach.


IODP: JOIDES Resolution Assessment Report and accompanying Community Survey Data Report - NEW!
We are pleased to announce the release of the JOIDES Resolution Assessment Report, and the accompanying JOIDES Resolution Community Survey Data Report, in support of the National Science Foundation’s request to the National Science Board for the renewal of funding for the JR facility for the next five years. The community overwhelmingly supports the JR and its ability to address high priority objectives of the IODP Science Plan. The Community Survey Data Report documents the responses of 876 of our colleagues, both national and international, and provides significant insights into the IODP community. The Workshop Report reflects the outstanding effort of the 81 attendees of the September 2017 workshop, “Assessment of the JOIDES Resolution in Meeting the Challenges of the IODP Science Plan”. Their tasks included developing expedition results reports in preparation for the workshop, reviewing comments from the Community Survey, and synthesizing the two datasets. The report includes the results of plenary sessions from the workshop that focused on future scientific opportunities that can be addressed in the next five years, as well as discussion surrounding the relationship of the JR to the National Science Foundation’s Sea Change report from 2015, in addition to a list of recommendations and updates for the next five years of JR operations.

MBL: Advanced Research Training Course: Strategies and Techniques for Analyzing Microbial Population Structures (STAMPS) - NEW!
Deep DNA sequencing using massively-parallel, next-generation technology has enabled nearly comprehensive environmental surveys that can describe the different kinds of microbes in a community and their relative abundance. These descriptions of richness and evenness make possible estimates of microbial diversity, but the size of the required data sets pose enormous computational challenges. The rapidly expanding flow of information from next generation DNA sequencing platforms has fueled healthy debate about best practices for data analysis while at the same time building a user demand for tools that can address important ecological questions. The STAMPS course will promote dialogue and the exchange of ideas between experts in analysis of metagenomic data and offer interdisciplinary bioinformatic and statistical training to practitioners of molecular microbial ecology and genomics. Application Deadline: April 20, 2018.
