The first talk normally starts at 11:00AM.? Each talk is typically 12 minutes long (similar to many professional meetings), with 8 minutes for questions. These talks will be presented via Zoom, with the following connection information: https://fsu.zoom.us/j/98491660566?pwd=NzBxNzN4LzdsbSs4R3B6RzliOGhhdz09 Meeting ID: 984 9166 0566 Passcode: 478314 Jan. 10th John Paul Irving: Quantifying the sequestration time of remineralized carbon dioxide in the California current ecosystem for different carbon flux plathways Description: Within the California Current Ecosystem particulate organic carbon (POC) vertically migrates based on different export pathways; sinking, subduction, and active transport. These various export pathways influence the depth of remineralization, a process in which heterotrophic zooplankton and bacteria utilize POC and release CO2 as a product of respiration. To quantify the sequestration time of this CO2 within the ocean a lagrangian patricle tracking simulation was conducted using the MITgcm Floats Package and HYCOM reanalysis data. Magnitudes of sequestration are then calculated for the different carbon flux pathways based on sequestration time scales and remineralization rates of the different export flux pathways.

Shawn Smith: The MarineFlux Project. Description: /MarineFlux: A user-friendly in-situ marine turbulent flux data service/, is envisioned to be a web access point for the dissemination of turbulent air-sea fluxes and the essential ocean and climate variables required to estimate the fluxes from surface in-situ platforms. The prototype service will include fluxes derived from the International Comprehensive Ocean-Atmosphere Data Set (ICOADS) and the Shipboard Automated Meteorological and Oceanographic System (SAMOS) initiative, along with select flux datasets from NOAA expeditionary cruises. The goal is to make access to in-situ fluxes easier for a wide user community. Mark Bourassa: Butterfly - a NASA proposal to measure air-sea fluxes. Description: Butterfly is a proposed NASA satellite-based mission to more accurate determine air-sea turbulent heat fluxes at relatively fine resolution. The mission concept will be outlined. I will talk a little about options to improve this mission. -------------- next part -------------- An HTML attachment was scrubbed...

All are welcome to attend. Meeting # 942 7359 5552 Schedule: Teatime - Virtual (via Zoom) * 3:00 to 3:30 PM Eastern Time (US and Canada) Colloquium - F2F (in 499 DSL) | Virtual (via Zoom) * 3:30 to 4:30 PM Eastern Time (US and Canada) Abstract: We present the results of simulations of magnetized, reactive turbulence for conditions expected to exist in outer layers of massive white dwarfs during the advanced stages of the deflagration-driven explosion. In the present scenario an initially quiescent, low density plasma is perturbed by the approaching flame front, which drives turbulence on large scales due to Rayleigh-Taylor (RT) instability, and self-heated by nuclear burning. We probe a parameter space of this problem by obtaining a series of models systematically varying characteristics of turbulence and initial strength of the magnetic field. The observed behavior is qualitatively similar to previously reported results of hydrodynamic simulations. Deflagration-to-detonation transition (DDT) is facilitated by the Zel'dovich reactivity gradient mechanism and occurs about 100 ms after the self-heating of plasma is enabled. Such relatively short detonation delay times are observed despite the fact that the turbulence is driven using relatively lower, realistic energies characteristic of the RT-driven supernova flame turbulence. The resulting turbulence Mach number is ~0.3. We find the DDT delay time is a sensitive function of the turbulence compressibility with shorter delay times observed in models in which most of the driving energy injected on large scales is in solenoidal modes. Such perturbations are consistent with the RT-driven turbulence. For realistic initial magnetic field values(~10 MG or higher), the field is rapidly amplified with the average plasma beta reaching about 0.1 well before carbon ignites. We discuss the magnetic field amplification mechanism, how the magnetic field participates in the process of preconditioning, and its role in accelerating DDT in the context of the Zel'dovich mechanism. Our results motivate observations aimed at measuring magnetic fields in Type Ia supernovae and future theoretical and computational studies of magnetized white dwarfs. -------------- next part -------------- An HTML attachment was scrubbed...
