Postdoctoral Fellowship in Ocean Dynamics Affecting Open-Ocean Productivity and High-Seas Salmon

Applications are invited for a two-year postdoctoral fellowship (PDF) to study mixed-layer dynamics and coastal-offshore exchange mechanisms inthe Northeast Pacific using a diverse collection of ocean observations including ocean glider, Argo float, ship-based, and satellite data.

Background: International Year of the Salmon (IYS) is a five-year initiative that aspires to establish the conditions necessary to ensure the resilience of salmon and people throughout the Northern Hemisphere. As part of IYS’s 2022 Pan-Pacific Winter High Seas Expedition, the IYS is funding a number of postdoctoral positions to create an interdisciplinary team of young scientists examining and integrating the ocean observations generated by 5 IYS cruises as well as other relevant data sources. There are substantial resources available to understand the relevant ocean physics.The IYS cruises will be collecting CTD/Rosette data and deploying specialized Argo floats equipped with oxygen sensors. This project will couple these in situ measurements with satellite ocean colour, altimetry, and sea surface temperature measurements to construct a synoptic picture of the North Pacific Ocean. Argo float data may also be used to understand hydrographic properties on a large scale and in the mixed layer, while Line P observations, collected from both regular research cruises and from autonomous gliders moving along Line P, provide an opportunity to construct a detailed picture of temperature, salinity, oxygen, and chlorophyll in the upper 1000 m of the ocean along the Line P transect. There is potential to collect additional glider observations, e.g.along a north-south section through the planned Gulf of Alaska sampling array, from the 2022 expedition.
