Siegel, David A.; et al. (2021): Assessing the sequestration time scales of some ocean-based carbon dioxide reduction strategies

Siegel, David A.; DeVries, Tim; Doney, Scott; Bell, Tom (2021): Assessing the sequestration time scales of some ocean-based carbon dioxide reduction strategies. In Environ. Res. Lett. DOI: 10.1088/1748-9326/ac0be0.

"Here, a model of steady state global ocean circulation and mixing is used to assess the time scales over which CO2 injected in the ocean interior remains sequestered from the atmosphere."

Job: Postdoctoral Associate (Stony Brook University)

Deadline: 19. June 2021

"Seeking a postdoc familiar with the marine carbonate system for an interdisciplinary project in the emerging field of ocean carbon dioxide removal (ocean CDR) and negative emissions technologies (NETs) that aims to mitigate ocean acidification while decreasing the atmospheric carbon dioxide concentration. The postdoc will help evaluate an electrochemical process that enables local adjustment and control of seawater carbonate chemistry."

Call for Proposals (Panels and Presentations): 1st Annual Conference on Carbon Removal Law and Policy

Deadline: 18. June 2021

"The focus of the conference will be on law and policy issues associated with ocean carbon removal approaches, including, but not limited to the following issues:

Governance of ocean-based carbon dioxide removal approaches at national and sub-national scales, as well as the role of international treaty regimes and principles of customary international law;

The role and application of principles of equity and social justice in ocean-based carbon dioxide removal research and deployment;

Methodologies for, and challenges in, constructing effective architectures for public engagement on ocean-based carbon dioxide removal approaches."

CNN: This startup grows kelp then sinks it to pull carbon from the air

"One Maine-based startup, Running Tide Technologies, is experimenting with farming kelp, a type of seaweed, in an effort to pull carbon from the air and store it deep beneath the ocean floor, potentially giving the world another nature-based tool to curb climate change."

Tyka, Michael; et al. (2021): CO2 capture by pumping surface acidity to the deep ocean

Tyka, Michael; Platt, John; van Arsdale, Christopher (2021): CO2 capture by pumping surface acidity to the deep ocean. Preprint. DOI: 10.31223/X5TK60.

"Here we present a method which relies purely on the redistribution and dilution of acidity from a thin layer of the surface ocean to a thicker layer of deep ocean, with the aim of reducing surface acidification and accelerating the former carbonate homeostasis."
