Drivers, Trends, and Impacts of Coastal Nuisance Flooding

MJO overview




The freqency and duration of coastal nuisance flooding is increasing expoentially in Annapolis, MD USA while relative sea level is rising at a near-linearly long term rate. This research focuses on trends in these processes and local- to synoptic-scale wind forcing perspective relative to the local geomorphology of the coastaline.

Intraseasonal Ocean Variabilty: Linking Surface Ocean Processes to the MJO

MJO overview



Tropical convection asociated with the Madden Julian Oscillation (MJO) forces poleward-propogating, upper -tropospheric Rossby waves that project onto the surface as variabilty in mean sea level pressure and winds. Because wind patterns play a significant role in upper ocean currents and physics, this research investiagtes surface ocean variabilty and response associated with MJO forcing.

MUltisensor STability And Chlorophyll Experiment (MUSTACHE) 

MJO overview




In this study, a quasi-lagrangian biofloat was deployed and profiled the water column every two days in the High Nirtate, Low Chollorphyll (HNLC) Drake Passage. This study observed and analyze the development and export of a naturally occurring phytoplankton bloom. Evidence suggests that eddy-driven subduction and a change in the vertical structure were important in the days leading up to direct carbon export. In addition, observations and machine learning modeling approaches suggest that low levels of mesoscale kinetic enegery are a precondition for bloom formation.
