PhD opportunity: Testing the vulnerability of life stages of marine calcifiers to changes in ocean chemistry (Marine Institute Cullen Fellowship)

Deadline: Friday, January 11, 2019

Project Description: Global change includes a wide range of environmental (physical and chemical) changes and is occurring faster than our ability to predict it’s consequences (Kroeker, Kordas & Harley 2017). Much work has been done since it was first observed that the oceans were acidifying (Doney et al. 2009; Feely, Doney & Cooley 2009), however, the diversity of responses among species to date prevents clear predictions about the impact of acidification at the ecosystem level (Kroeker et al. 2011). The first generation of ocean acidification experiments focused on the physiological responses of individual organisms, usually calcified organisms because those were assumed to be most vulnerable (Widdicombe & Spicer 2008; Melzner et al. 2009; Dupont, Ortega-Martinez & Thorndyke 2010). These were followed by a wave of studies that also attempted to include wider community level responses and various proxies for ecosystem functioning (Hale et al. 2011; Russell et al. 2012; Murray et al. 2013; Queiros et al. 2015; Sunday et al. 2017). More recently, the factors that currently limit our understanding have been identified based on our knowledge that CO2 driven environmental change comprises a suite of stressors with different, sometime opposing, patterns of occurrence and effects of species (Kroeker, Kordas & Harley 2017). The interactions between ocean acidification (OA) and other natural or anthropogenic pressures can result in positive or negative net effects (Boyd & Hutchins 2012), which can determine individual species responses (Breitburg et al. 2015; Kroeker et al. 2016). Context is, therefore, critical for forecasting the ecological effects of OA and it is recommended that future studies should span a wide range of conditions to accurately interpret empirical results (Kroeker, Kordas & Harley 2017). Furthermore, the combined effects of multiple stressors on individual species can be mediated by their interactions with other species in an ecosystem (Alsterberg et al. 2013). It is, thus, imperative that the next generation of OA studies include diverse, functioning ecosystems that incorporate species interactions and compensatory dynamics (Kroeker, Kordas & Harley 2017).

Postdoctoral Associate, Stony Brook University

Deadline for applications: 16 December 2018.

Brief Description of Duties:
The selected candidate will assist in the analysis of large-scale genomics data (RNASeq, RADSeq) to answer questions pertaining to the molecular mechanisms associated with the resilience of bivalve mollusks to pathogenic and environmental stress.

• Carry out research that allows the identification of genetic features and molecular pathways associated with bivalve resilience and response to environmental (e.g. ocean acidification, food limitation) and pathogenic stress. This includes planning and study design, wet lab experimentation with mollusks, nucleic acid extraction, high-throughput sequencing and data analysis using modern bioinformatics tools.

Staff chemist- ocean acidification (Mote Marine Laboratory

Deadline to apply: 5 October 2018

The Ocean Acidification Program at Mote Marine Laboratory seeks a staff chemist with a minimum 2 years experience with experimental seawater ocean acidification facilities including carbonate chemistry experience. This position will be located in Summerland Key, Florida at the Elizabeth Moore International Center for Coral Reef Restoration and Research (IC2R3). General duties to be performed include working with research-focused outdoor raceways and the OAFTERU (Ocean Acidification Flow Thru Experimental Raceway Units) at IC2R3. This includes maintaining the water system, sample collection, measuring total alkalinity, dissolved inorganic carbon, spectrophotometric pH, and other water quality parameters. Tasks also include maintaining the dry ocean acidification (OA) laboratory, maintaining the dry chemistry laboratory, keeping track of and ordering all supplies and materials, keeping all OA-related work organized, data entry, and some field work.

Job opportunity: postdoctoral scholar in chemical oceanography/metrology

Location: Gaithersburg, Maryland, USA

Position: The University of Delaware (UD) College of Earth, Ocean, and Environment invites applications for a Postdoctoral Research Scientist position in chemical oceanography and metrology. The successful candidate will work on a NOAA funded project to aid in development of a reference material for ocean pH by establishing traceability of pH indicator dyes to the International System of Units (SI). The scholar will make use of state-of-the-art analytical and experimental facilities at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland, where the position will be located (with the appointment made through the University of Delaware). The postdoc will also attend field test cruises with the UD group. The appointment will be for one year, with continuation pending funding and progress. 

Requirements: Candidates must have a PhD in either chemical oceanography, analytical chemistry, or a closely related field. Demonstrated skills with spectrophotometry, potentiometry, nuclear magnetic resonance spectroscopy, and/or physical chemistry are preferred.

Application deadline: position will remain open until filled.

Job opportunity: Marine ecology and ocean acidification research technician

Location: California State University, Northridge (CSUN)

Start Date: October 1, 2018

Application deadline: August 26, 2018

Duties: to support research in coral reef and rocky intertidal ecology. The successful candidate will work under the supervision of Dr. Nyssa Silbiger (nyssa.silbiger@csun.edu) and will support research conducted mostly in California, but also possibly in Hawaii, Bermuda, and/or Moorea, French Polynesia. The primary responsibilities will be supporting all aspects of the logistics required for maintaining ocean acidification mesocosm experiments and near-shore marine research in the field.

Requirements: A Bachelor’s degree in marine ecology, biology, oceanography, or a related-field is required. The ideal candidate will have a Master’s degree in a field- based marine biology topic, experience maintaining mesocosm facilities for ocean acidification research, a background in seawater chemistry, an understanding of the biology/ecology of marine organisms, and strong experience with fieldwork (e.g., SCUBA diving, operating small boats, AAUS training, etc.). Candidates will be expected to pay attention to detail, problem solve, work both independently and with a diverse team of students and faculty, and have a strong work ethic. Additional preferred, but not required, qualifications include experience coding in R and writing peer-reviewed publications.

PhD opportunity: Monitoring Arctic ocean acidification from space using satellite earth observations

Deadline for applications: 31 August 2018

Description: About one third of the CO2 released into the atmosphere by anthropogenic activity since the Industrial revolution has been taken up by the oceans, resulting in a shift in marine carbonate chemistry, including a decrease in seawater pH and carbonate ion concentration; a situation referred to as ‘Ocean Acidification’ (OA). The majority of scientific efforts to-date for monitoring, observing and predicting the effects of OA have focused on using models and in situ studies (such as buoys, research cruises and laboratory- or field-based studies). Satellite Earth Observation (EO) has yet to be fully exploited in this area of research, but could play an important role in monitoring changes in oceanic carbonate chemistry, as well as assessing vulnerable regions, as they can provide quasi-synoptic, reproducible and well-calibrated measurements. A recent European Space Agency pilot project ‘Pathfinders Ocean Acidification’ highlighted
this approach (Land et al. 2015) and then established that satellite observations can in fact reproduce carbonate parameters with accuracy comparable to in situ or model-driven approaches. However, the Pathfinders-OA project also highlighted some regions where the empirical algorithms underperformed and further development is needed, including the Arctic Ocean.
