Bringing light to life: a global study of the interface between underwater light and marine phytoplankton

Historically, oceanographers have used the pigment chlorophyll-a as the primary currency of photosynthetic biomass because it is relatively simple to measure in seawater and is found in all marine phytoplankton. Yet, both the light reactions of photosynthesis that ultimately fuel the metabolism of photoautotrophs and the colour of the ocean used to detect chlorophyll biomass from space are related to the absorption of photons by all phytoplankton pigments in phytoplankton and not by a single pigment. Using bio-optical measurements collected across the global ocean (from field observations and from satellites), this project will look beyond chlorophyll-a and develop a mechanistic understanding of how light energy is processed by the ocean’s microflora whose growth supports the rest of marine life and makes phytoplankton a key player in the global carbon cycle.

This project is part of the DPhil in Earth Sciences at the University of Oxford. Funded places are awarded on a competitive basis according to academic achievement and potential to excel as a DPhil student.

The deadline for applications for 2023-2024 entry is early January 2023. Late applications will not be considered for scholarship funding.

Senior Engineer (Electronics, Optics and Metocean), NASA-MarONet, Curtin University, Perth

Full-time, fixed term 2-year position

Project description:
MarONet is a marine optical buoy to be deployed off Perth, Western Australia. A similar system is deployed in Hawaii.
These buoys are equipped with state-of-the-art hyperspectral radiometers, whose measurements are used to derive the reflectance of the ocean in the visible domain. The data will be used for what is called the “System Vicarious Calibration” of the NASA “PACE” mission, to be launched in 2024 (https://pace.gsfc.nasa.gov).  MarONet is funded by the US NASA, with University of Miami (UM, Florida) being the prime contracted institution, and Curtin University (Perth, WA) being contracted under UM.

Summary job description:
The proposed position consists in managing the equipment, which includes two sister buoys. Activities include reception of the equipment from the US, its assembly and testing in the Curtin facility that will host the project, organising its deployment and actively participating to the deployment, servicing the equipment on site (at sea; off Perth) on an approximately monthly basis, on-site swap of the two sister buoys, shipment of the recovered equipment to the US for re-calibration. The first 6 months of the activity will include frequent interaction with the Hawaii team, and also travel to the Hawaii facility for training on the preparation and deployment of the buoys.

A sun-photometer site will also be developed on Rottnest Island as part of the AERONET (https://aeronet.gsfc.nasa.gov), which will also require regular servicing.

The project is led in Perth by Prof. David Antoine, head of the remote sensing and satellite research group, to whom you can also direct any questions at david.antoine@curtin.edu.au

2-year postdoctoral position in remote sensing of inland water algal blooms

Environment and Climate Change Canada’s Water Science and Technology Directorate is seeking applicants through the Postdoctoral Research Program to work on satellite Earth observations of inland water harmful algal blooms. The postdoc will be based at the Canada Centre for Inland Waters in Burlington Ontario, and will work under the supervision of Dr. Caren Binding.

The successful candidate will contribute to one of two projects:

(1)    Assessing climate and watershed drivers of algal blooms across Canada. This project will integrate land use, climate reanalysis, and lake remote sensing datasets across a number of watersheds to further understand regional drivers of spatio-temporal variability in bloom severity. Work will support ECCC’s effort to develop ecological indicators, guide nutrient reduction strategies and adaptive lake management. Experience with cloud-based EO data and analytics platforms (e.g. MS Azure, Google Cloud Platform, Sentinel-hub, CREODIAS, Google Earth Engine) would be an asset. The successful candidate will have strong programing skills (e.g. Python, JavaScript) to support application development on those platforms. Experience with machine learning and/or geospatial statistical approaches would be welcome.

(2)    Satellite-derived phytoplankton community composition for enhanced algal bloom monitoring. This project will characterize optical properties of phytoplankton natural assemblages and isolated cultures in order to test existing, or develop new, algorithms for retrieving bloom community composition from hyper- and multi-spectral satellites.  Work will support ECCC’s efforts to prepare for NASA PACE data streams and application demonstration for a proposed future WaterSat hyperspectral mission. Experience with laboratory (UV-VIS spectrophotometry) or field (radiometry, IOPs) optical instrumentation and familiarity with radiative transfer modeling would be an asset. The successful candidate will be willing to work in the laboratory and field, contributing to field campaigns on Lakes Erie, Winnipeg and/or Lake of the Woods.
