Postdoctoral Position in validation and deployment of chemical sensors in marine waters

Topic: Improvement of measurement metrology for chemical sensors

starting on June 1st 2018.

Project Description:
The EU-BMWi project OCEANSensor draws together European companies and research organisations (from Germany, France, Norway, UK) developing, validating, marketing and deploying marine biogeochemical sensors. OCEANSensor aims to improve and utilise the latest sensor, platform and communication technologies to be used for marine biogeochemical observations. The project will refine existing sensor technologies, develop new applications, and demonstrate complete technology solutions for new, in situ marine sensors and observation systems for biogeochemical parameters in coastal and oceanic waters. An important aspect will form the improvements to measurement metrology (accuracy and stability), by performing in-situ calibrations in order to take quality and traceability of data to a new level. Biogeochemical parameters of interest to OCEANSensor are among the Essential Ocean Variables as defined by the Global Ocean Observing System within the Framework for Ocean Observing, namely oxygen, nutrients, and inorganic carbon.

OCEANSensor has the following objectives:
• make a step change in the measurement metrology of pH, pCO2 and oxygen optodes through the development of miniaturised reference solution delivery systems
• improve in situ detection of nitrate in seawater using hyperspectral optical sensors
• produce, test, and demonstrate lab-on-chip sensors for phosphate and ammonium
• enhance measurement metrology of nutrient sensors through the development of in situ certified reference material utilisation
• develop a mechanical in situ cross-referencing system for validation of sensors for benthic flux quantification
• demonstrate carbonate chemistry and nutrient sensors on platforms including moorings, Argo floats, surface roaming vehicles and a cabled observatory

Job Description:
The candidate will be part of a European team that will develop, validate, and deploy biogeochemical sensors for marine waters. The candidate will be working closely with a German and a Norwegian company involved in development and sales of chemical sensors. The candidate will contribute to the objectives of OCEANSensor, and enhance the metrology of chemical sensors, and validate and deploy the sensors. Laboratory experiments will be conducted to improve measurement metrology. It is expected that the candidate will participate in sea-going expeditions where she/he will be part of a team studying water column carbonate chemistry, oxygen and nutrients, using both tradional laboratory analytical techniques for sample analyses following collection during field and vessel surveys, and using novel in situ chemical sensor systems. The candidate will perform the fieldwork with subsequent sample and data analysis, data interpretation, and report and scientific manuscript publication. The candidate will need to communicate routinely with other members of the OCEANSensor programme and will contribute to the project management of the OCEANSensor programme

• A Master/Diplom and a PhD in chemical oceanography or similar field is required
• Experience in analytical measurements for nutrients, oxygen, carbonate chemistry variables and DOC in marine waters is required
• We expect excellent English language skills and experience with working on research vessels.
• The candidate should be willing and able to participate in sea-going expeditions.

The position is available for a 36 months funding period. The position is subject to a final funding approval by the BMWi. The salary will be according to class E13 TVöD of the German tariff for public employees.This is a full-time position according to 100% of a full-time equivalent. The position can be split.
