Linking Oxygen and Carbon Dynamics to Deep Water Formation Using New Sensor Observations in the Labrador Sea
Dariia Atamanchuk, Dalhousie University
Abstract:
Uptake by the ocean and distributions of key components of the life cycle – oxygen (O2) and carbon dioxide (CO2) – have a profound effect on the ocean’s health and on its capacity to continue mitigating the effects of climate change. The Northwest Atlantic region exerts a disproportionally large control on deep water properties with respect to concentrations of O2 and CO2. Yet, collecting data on proper spatio-temporal scales to constrain and quantify the processes responsible for gas uptake and distributions in the region is often prohibitive due to weather and the remote location. New autonomous ocean observations are transforming our view of the ocean, and the multiparameter profiling platforms, like SeaCycler and BGC-Argo, and mooring-based chemical sensors help fill the data gaps. The talk will focus on the status of biogeochemical observations in the region with a particular focus on the linkages between gas uptake and the deep convection.

210Po-210Pb Dynamics and Particle Export in the Western Arctic Ocean
Wokil Bam, WHOI
Abstract:
The naturally occurring 210Po (t1/2=138.3d) and 210Pb (t1/2=22.3 y) radionuclide pair has been extensively used to study particle scavenging, cycling and transport in the ocean. However, the role of particle composition and concentration in the scavenging, sorption and fractionation of 210Po-210Pb needs to be better understood to successfully utilize these radionuclides as oceanographic tracers. My talk includes two major parts: in the first part, I will present the role of the concentration and composition of suspended particulate matters in scavenging and fractionation of these radionuclides in the western Arctic Ocean, the distribution, and disequilibria of 210Po and 210Pb in the western Arctic Ocean. In the second part, I will present the vertical fluxes of particles by utilizing the 210Po and 210Pb fluxes in both the Arctic.

Gender Differences in NSF Ocean Sciences Awards
Ivan Lima, WHOI
Abstract:
We examine how women’s representation in National Science Foundation Ocean Sciences (NSF-OCE) awards has changed between 1987 and 2019 and how it varies across different programs, research topics and award types. Women’s participation in NSF-OCE awards has increased at a rate of approximately 0.64% per year, and the similarity between the temporal trends in the NSF-OCE awards and the academic workforce suggests that there is no gender bias in NSF funding. The programs, topics and award types related to education show the strongest growth, achieving and surpassing parity with men, while those related to the acquisition of shared instrumentation and equipment for research vessels have the lowest women’s representation and show relatively little change over time. Despite being vastly outnumbered by men, women PIs tend to do more collaborative work and have a more diversified “portfolio” of research and research-related activities than men. We also found no evidence of gender bias in the amount awarded to men and women PIs.

Diversifying Oceanography: The Coastal Ocean Environment Summer School in Ghana;
Brian Arbic, University of Michigan, and Winn Johnson, University of North Carolina Wilmington
https://lsa.umich.edu/earth/people/faculty/arbic.html
https://uncw.edu/chem/faculty/facstaff-johnsonw.html
Abstract: Modeling and observing the global ocean environment requires a coordinated global effort. Yet, as in most STEM disciplines, Africans are under-represented in the global oceanography enterprise. The need, and the potential, for changing this is clear. The coastal resources of Africa, the world's second-largest continent, face many pressures including erosion due to sea-level rise, offshore oil drilling, increased shipping, overfishing, piracy, and others. At the same time, Africa has a young, rapidly growing population, and has several of the world's fastest-growing economies. The time is ripe for developing STEM partnerships between Africa and the rest of the world, and a more diverse global scientific community will benefit everyone.With the above motivations in mind, we developed the Coastal Ocean Environment Summer School in Ghana. Following an exploratory trip in 2014, during which we met potential partnering institutions, we have been running the school for one week every August since 2015. The hosting Ghana institution alternates between Regional Maritime University (RMU), which trains West Africans for careers in shipping, port management, and other marine sector careers, and the University of Ghana (UG), which has a marine and fisheries sciences department. Over time the school curriculum has grown to include hands-on labs, a boat trip, instrument deployments, field trips to beaches and ports, and short research projects, in addition to lectures. From 2016-2019, about 100 West Africans participated per year. The school has a regional impact; an increasing number of participants come from Nigeria and other countries outside of Ghana. Instruction is done by resource persons from Ghana, the US, and Europe. Global north participants have included undergraduates, graduate students, postdocs, and professors/research scientists.We will briefly discuss school success stories, our experience running the school virtually in 2020 (for about 60-70 participants), funding challenges, and our vision for the future of the school.
