#Oceanography Development Meta

#Manganese Nodules | Mineral concretions on sea bottom formed of concentric layers of iron and manganese hydroxides around core

#Ferromanganese nodules | Mineral concretions composed of silicates and insoluble iron and manganese oxides that form on ocean seafloor

#Polymetallic nodules | Contain four essential base metals: cobalt, nickel, copper and manganese, in a single ore | Formed over millions of years by precipitating metals from seawater and sediment pore water | Lie unattached to abyssal seafloor | Unlike land ores, do not contain toxic levels of heavy elements | Producing metals from nodules has the potential for to productize nearly 100% of nodule mass and design a metallurgical flowsheet that generates no tailings and leaves nearly no solid waste streams behind

#ROS 2 | The second version of the Robot Operating System | Communication, compatibility with other operating systems | Authentication and encryption mechanisms | Works natively on Linux, Windows, and macOS | Fast RTPS based on DDS (Data Distribution Service) | Programming languages: C++, Python, Rust

#Agentic AI | Artificial intelligence systems with a degree of autonomy, enabling them to make decisions, take actions, and learn from experiences to achieve specific goals, often with minimal human intervention | Agentic AI systems are designed to operate independently, unlike traditional AI models that rely on predefined instructions or prompts | Reinforcement learning (RL) | Deep neural network (DNN) | Multi-agent system (MAS) | Goal-setting algorithm | Adaptive learning algorithm | Agentic agents focus on autonomy and real-time decision-making in complex scenarios | Ability to determine intent and outcome of processes | Planning and adapting to changes | Ability to self-refine and update instructions without outside intervention | Full autonomy requires creativity and ability to anticipate changing needs before they occur proactively | Agentic AI benefits Industry 4.0 facilities monitoring machinery in real time, predicting failures, scheduling maintenance, reducing downtime, and optimizing asset availability, enabling continuous process optimization, minimizing waste, and enhancing operational efficiency

#Ocean swells | Waves in a fully developed sea outrun the storm that creates them | Traveling great distances from the wind source | Lengthening and reducing in height in the process | Lower frequency waves are called swell waves | Organize into groups smooth and regular in appearance

#Southern Ocean Heat Burp in a Cooling World | Simulating several hundred years of net-negative emissions and gradual global cooling | Abrupt discharge of heat from Southern Ocean modeled | Global mean surface temperature increase of several tenths of degrees lasting for more than a century modeled | Ocean heat burp reasoned to originate from heat previously accumulated under global warming in deep Southern Ocean | Multi-centennial scale climate simulations | Question of the durability of oceanic storage of heat and carbon more urgent as ocean warming is accelerating | As atmospheric CO2 strongly decreases and atmospheric temperature declines, carbon and heat stored in the ocean start to return to the ocean surface | The majority of interior ocean waters ultimately returns to Southern Ocean surface and is reexposed to atmosphere in Southern Ocean | In Southern Ocean density layers outcrop at ocean surface, directly connecting surface to interior ocean thereby regulating oceanic exchange with atmosphere | Combined with persistent large-scale upwelling, Southern Ocean is prominent candidate for release of heat and carbon from ocean interior under reversal of atmospheric CO2 and global cooling | 40% of oceanic uptake of carbon | 80% of oceanic uptake of heat | Earth system model | Mass and energy conserving University of Victoria model UVic | Simulations of long time scales and carbon cycle feedbacks | UVic features atmospheric energy-balance model, ocean circulation and sea-ice model, land biosphere and ocean biogeochemistry with two plankton groups | Horizontal resolution: 3.6 × 1.8 | Ocean model; 19 vertical z-layers with increasing thicknesses over depths from 50m to 500m | Ocean Heat Release Causes Warm Period | Accumulated Heat Pushing up in Southern Ocean | Large-scale upwelling of deep waters in Southern Ocean keep surface temperatures comparatively cool | Southern Ocean serves as window to atmosphere, abruptly releasing heat during event and driving global surface warming and top of atmosphere energy loss, causing heat burp | Climate and Earth system models do not simulate changes in ice sheets and consequently miss the effect of freshwater input to ocean associated with ice sheet mass loss under global warming | Melt water discharge from Antarctic ice sheet triggered by global warming will have an additional, long-lasting freshening effect | Model used lacks a full response of the wind | Model also misses cloud feedbacks | Research underlines both importance of Southern Ocean in climate system and its response to changes in climate system beyond heat and carbon uptake under contemporary rising global temperatures | It is important to continue to improve process understanding of how waters return from interior Southern Ocean and what determines their properties | Interactive ice sheets needed | Observational data collection needed | Deep Argo observing waters below 2,000 m depths needed | Ack: research-unit Biogeochemical Modeling and funding by European Research Council (ERC)
