"Stochasticity of Turbulence"
By
Iury Simoes-Sousa
PhD Candidate, Department of Estuarine and Ocean Sciences

Abstract:
Ocean and atmosphere models are usually run in very coarse resolution compared to most of the turbulent energy cascade. The standard approach is to parameterize the turbulence expressed by an extra diffusion. Physics-based models are highly diffusive and do not capture the backscattering of the energy cascade to larger scales. More recent approaches have tried to use machine learning methods to solve this problem, but they are usually not generalizable. This work is a first step in investigating whether turbulence closures should be stochastic instead of deterministic. The main question is, how different is the subgrid stress between different noise-added ensembles for a given coarse-grained flow field?

Weekly Seminar Announcement
"Modeling study of ocean acidification in the US northeast coastal region"
By
Lu Wang
PhD Candidate
Department of Fisheries Oceanography
Wednesday, September 14, 2022
2:30 pm - 3:30 pm
SMAST East, Rooms 101/102
and via Zoom
Abstract:
The ocean acidification (OA) condition in the US northeast coastal region changes over multi-time scales, with upwelling caused by Warm Core Rings (WCRs) and Warm Core Eddies (WCEs), the coastal river discharge, and a long-term variability due to climate change-induced interannual-decadal fluctuation of atmospheric CO2 loading and the global warming. However, the contribution of these factors to OA requires comprehensive regional studies in the US northeast coastal region. The variability is manifested through the fully nonlinear interaction of physical, biological, and chemical processes. The Northeast Biogeochemistry and Ecosystem Model (NeBEM) was developed and validated for the year 2017 and 2018 to estimate the contributions of WCRs and WCEs to the nitrogen and carbon flux over the US northeast shelf region. During January to April, the results showed that the fluxes were 29%, 26%, and 33% higher over the WCRs and WCEs periods in Scotia Shelf, Northeast Chanel, and Mid-Atlantic Bight, respectively. The WCRs and WCEs intrusion significantly reduced the offshore nutrient flux over the Georges Bank. Sensitivity studies were conducted to quantify the contribution of increased atmospheric CO2, sea surface temperature (SST), and river discharges. By the year of 2050, the vertically averaged aragonite saturation state ( ) will decrease 1-11% in the condition of atmospheric CO2 increased at a rate of 2.18ppm/y. The increased SST (2.24 °C) will intensify the circulation of Georges Bank. Furthermore, the vertically averaged will increase 3-13% under this condition. However, the influence on OA of both increased atmosphere CO2 and increased SST will almost cancel with each other at this increasing rate with a change rate of between -1-1%.
