Ocean acidification

Affiliation: Alfred-Wegener-Institute Helmholtz Centre for Polar and Marine Research Biosciences, section Integrative Ecophysiology

Start date: Immediately

Background:

We use physiological, biochemical and molecular methods to study how temperature and ocean acidification acutely and chronically affect hormonal regulation of moulting and growth in Decapod crustaceans. We focus on cellular signalling mechanisms within tissues that control the moulting cycle, and on mechanisms that are involved in the cross-talk between organs.

Different life history stages of species from temperate and subpolar latitudes may vary in their capacities for growth, hormonal, acid-base and ion regulation. This may contribute to different thermal tolerances and sensitivities to climate change scenarios.

In the framework of the project CARIOCA (Coral reef acclimatization to ocean acidification at CO2 seeps) we collected corals living at two CO2 seeps in Papua New Guinea and at control stations. We also reciprocally transplanted for four months these corals, which seems to be less sensitive to high pCO2 (the winners), and some others which where only found at control stations (the losers). Our main goal is to associate both long- and short-term studies in gene expression together with changes in organism physiology.

We are seeking to appoint an accomplished and motivated candidate to the position of Postdoctoral Research Fellow to work during 15 months on this unique new project. The post-doc will have in charge to analyse the coral transcriptomic data. She/he will have to annotate and compare gene expression between resident and transplanted corals (intra- and inter-species comparisons) and perform de novo transcriptomes for non-model species. Using her/his knowledge in cell functioning and cell genetics, the candidate has to explore the paradigm of adaptability versus acclimatization and to puzzle out the pathways that might drive the corals sensitivity and resistance to ocean acidification.

Applications are invited from suitably qualified candidates for a full time, fixed term position as a Research Assistant with the Ryan Institute at the National University of Ireland, Galway. This position is funded by the Marine Institute and is available from March 2017 for 3 years.

The Ryan Institute is the National University of Ireland, Galway’s hub for Environmental, Marine and Energy research and contributes to some of the most important national and international, long-term, environmental, marine and energy research issues. Staff from a range of disciplines and schools across the University contribute to research in the Institute. The research project to which this post will be linked includes staff from the School of Natural Sciences (disciplines of Earth & Ocean Sciences and Botany) and from the School of Physics.

Job Description:

The successful candidate will be involved in day to day support for a range of research activities involving physical, chemical and biological studies related to ocean acidification (OA). The post will be based partly at NUI Galway’s Ryan Institute and partly at the Marine Institute in Rinville, Oranmore, Co. Galway, as different phases of the project are undertaken. The project involves a considerable amount of fieldwork which will involve travel and some out of hours work, and will include seagoing work. Training for specific skills will be given where required. Candidate will have the opportunity to become involved in the development of a CPD module in ocean acidification and biogeochemistry suitable for persons involved in environmental monitoring.

GEOMAR Helmholtz Centre for Ocean Research Kiel is a foundation of public law jointly financed by the Federal Republic of Germany (90%) and the state of Schleswig-Holstein (10%) and is one of the internationally leading institutions in the field of marine sciences. Currently GEOMAR disposes over an annual budget of approx. 72 million Euro and has approx. 950 employees.

The GEOMAR Helmholtz Centre for Ocean Research Kiel is offering a Scientist position in Climate change and Stress Biology of marine invertebrates starting on October 1st, 2017 and ending on March 31st, 2021
in the research unit “Benthic Ecology” of the research division “Marine Ecology”.

Job Description / Duties

Climate change will not only shift environmental means but will also increase the variability around these means. This project should investigate the role of increased variability vs. increase in mean stress (from e.g. ocean warming, ocean acidification, desalination, hypoxia) for marine Baltic Sea invertebrate species and its consequences at the population level of species. This research project will make use of novel computer-controlled indoor mesocosm facilities simulating various pattern of environmental variability.

The Department of Marine Sciences (DMS) at the University of Connecticut (UConn) anticipates an opening for a tenure-track Assistant Professor in Benthic Ecology or Biogeochemical Modeling starting in Fall 2017.

Benthic Ecology:  We seek candidates whose research employs a combination of theoretical, empirical, and field approaches. All areas of marine benthic ecology will be considered, but candidates whose research involves the interactions of anthropogenic and natural factors on benthic processes, adaptations of benthic populations to changing environments, and novel technical or methodological approaches (e.g., ecosystem modeling, statistical modeling, meta-analyses, and molecular analyses) will be given priority.

Biogeochemical Modeling:  We seek candidates whose research interests include cycling of important elements in biogeochemical cycles in the ocean, the influence of anthropogenic factors on these cycles, and the interaction of these cycles with ecosystem dynamics, and climate. Areas of expertise can span from human to geological time scales and from estuarine to global spatial scales. We seek applicants that can 1) construct new models or advance existing models and 2) can place field-based measurements into a quantitative, process-based framework.

The successful candidate’s research should complement the existing research programs in DMS. Opportunities exist for collaboration within the interdisciplinary environment of DMS, as well as with colleagues in other departments at UConn. Teaching duties include undergraduate and graduate courses that support the DMS curriculum, as well as specialized courses in the candidate’s area of expertise. Advising undergraduate and graduate students is required. Professional service to the Department, the University, and the scientific community is expected.

Successful candidates will also be expected to broaden participation among members of under-represented groups; and develop, as appropriate, pedagogical techniques designed to meet the needs of diverse learning styles and intellectual interests.

The Atmospheric and Oceanic Sciences Biogeochemistry group at Princeton University is seeking applicants for a postdoctoral position in the area of modeling climate impacts on global fisheries. The position is part of a long-term multi-institutional effort, the Nereus Program, established in collaboration with the Nippon Foundation and University of British Columbia to improve multi-decadal scale predictions of global ocean fisheries.

The individual will join a vigorous interdisciplinary research group under the joint direction of Prof. Jorge Sarmiento of Princeton University and Dr. Charlie Stock of NOAA’s Geophysical Fluid Dynamics Laboratory. He/she will also be able to take advantage of a wide range of related research at Princeton University and at Nereus partner institutions: The University of British Columbia, Duke University, University of Cambridge, Stockholm University and the University of Utrecht. Areas of particular interest for this position include: improving biogeochemical climate-change projections, expanding these projections to improve their utility for fisheries and living marine resource impact assessments, and developing more mechanistic and integrated representations of climate-fisheries interactions.
