The heterogeneity and volatile content of Earth's mantle, magmas and crust
(Massachusetts Institute of Technology, 2021)
This thesis explores the volatile content of the mantle, subducted oceanic crust, and arc magmas as well as the structure of slow spreading ocean crust and the heterogeneity of Earth's upper mantle. In Chapter 2, I directly ...
Diagnosing the variability in temperature and velocity in the Middle Atlantic Bight
(Massachusetts Institute of Technology, 2021)
Observations of hydrographic and dynamical properties on the Middle Atlantic Bight shelf document strong variability at time scales spanning events that last a few days to century long trends. This thesis studies individual ...
The role of zooplankton in regulating carbon export and phytoplankton community structure : integrating models and observations
(Massachusetts Institute of Technology, 2021)
In this thesis, I explore two topics in plankton ecology with a combination of models and observations. First, I investigate the contribution of zooplankton diel vertical migration (DVM) to the vertical flux of carbon as ...
Coral reefs in the anthropocene ocean : novel insights from skeletal proxies of climate change, impacts, and resilience
(Massachusetts Institute of Technology, 2021)
Anthropogenic emissions of greenhouse gases are driving rapid changes in ocean conditions. Shallow-water coral reefs are experiencing the brunt of these changes, including intensifying marine heatwaves (MHWs) and rapid ...
Structure and mechanics of the subducted Gorda Plate : constrained by afterslip simulations and scattered seismic waves
(Massachusetts Institute of Technology, 2021)
Subduction zones host the greatest earthquakes on earth and pose great threat to human society. The largest slip in megathrust earthquakes often occurs in the 10-50 km depth range, yet seismic imaging of the material ...
Distribution, growth, and transport of larval fishes and implications for population dynamics
(Massachusetts Institute of Technology, 2021)
The early life stages of marine fishes play a critical role in population dynamics, largely due to their high abundance, high mortality, and ease of transport in ocean currents. This dissertation demonstrates the value of ...
