Biophysical interactions in the Iceland Basin
The Iceland Basin in the N. Atlantic has attracted considerable recent attention because the spring bloom in this region acts as the most powerful biological carbon pump anywhere in the world oceans. Furthermore, the link between primary productivity and herbivory by the calanoid copepod, Calanus …

Biophysical interactions and stability at salt marsh margins
… this cascading effect is strongly affected by biophysical feedbacks. Thus, the identification of locations of structural ‘weakness’ at the between-site and within-site scales could provide a conceptual framework for better understanding and prediction of erosion at near-vertical salt marsh …

A Lagrangian perspective of mesoscale biophysical interactions in the subtropical ocean
… and the associated biological responses (i.e., biophysical interactions) are not spatiotemporally static, so they are difficult to characterize. In this thesis, we interpret phytoplankton observations in an objective Lagrangian manner, or with a frame of reference that follows the motion of …

Submesoscale Biophysical Interactions on the Gulf Stream: Eddies, Fronts, and New Observational Methods
… eddy as a mesocosm for physical-ecological interactions and for their ecological impact on the mid-Atlantic Bight.</p>

Exploration of Biophysical Interactions Associated with Mesoscale Variability in the Central Gulf of Mexico
<p>Bio-physical coupling in the Gulf of Mexico (GMx) is explored in this research using an integrated satellite sensor approach. Physical features are identified using Sea Level Anomaly (SLa) produced by Archiving, Validation, and Interpretation of Satellite Oceanographic data (AVISO). Biological …

Single-molecule methods for an improved understanding of biophysical interactions: from fundamental biology to applied nanotechnology
… unprecedented amount of detail about molecular interactions in real-time. Single-molecule biophysical techniques have provided unique insights into the nature of protein-DNA interactions, and have allowed for the development of novel platforms to study nano-bio interactions. In this thesis, we …

Movements and oceanographic associations of large pelagic fishes in the North Atlantic Ocean
… as fronts and eddies, in the open ocean, the biophysical interactions occurring at the oceanic (sub)mesoscale (< 100 km) remain poorly understood. This leads to a paucity of knowledge on oceanographic associations of pelagic fishes and hinders management efforts. With ever-improving …

Adaptation of Biophysical Platforms to the study of Blast Injury
… a more complete picture of the underlying biophysical interactions. Thirdly, an ex vivo organ culture (EVOC) model system has been adapted to create a preclinical model of the combined effects of mechanical trauma and infection in respiratory tissues. This system, in tandem with …

Suspended Micro/Nanofiber Hierarchical Scaffolds for Studying Cell Mechanobiology
… To further investigate single cell-ECM biophysical interactions, nanofiber nets fused in crisscross patterns were manufactured to measure the "inside out" contractile forces of single mesenchymal stem cells (MSCs). The contractile forces (18-320 nano Newton) were found to scale with …

13C PEG as an In Vivo Macromolecular Probe for MRI and Biophysical Studies of Detergent-Peptide and Detergent-Detergent Interactions using NMR
… rats. The second part of this thesis describes biophysical interactions of detergents with either peptides or other detergent molecules. Firstly, the effects induced by a single polar substitution on the structure and topology of model α-helical transmembrane segments were investigated. Upon …

Vertical fluxes in the upper ocean
Oceanic fronts at the mesoscale and submesoscale are associated with enhanced vertical motion, which strengthens their role in global biogeochemical cycling as hotspots of primary production and subduction of carbon from the surface to the interior. Using process study models, theory, and field …

Dynamics of protein-membrane interactions in drug metabolism and cancer
… One must therefore study protein-membrane interactions deeply to fully understand how organisms function. For example, the orientation of certain protein domains on membranes might impact substrate access, lipid binding, and effector engagement. This highlights the fact that physical …

Molecular Dynamics Simulations for the Study of Biophysical Processes on Biological Membranes
… they play a central role in biochemical and biophysical processes at the cellular level, including cell protection, intercellular interactions, trans-membrane transport, cell morphology, and protein function, to name a few. The properties of phospholipid bilayers are thus of great interest …

Seabird foraging in dynamic oceanographic features
… This research demonstrated the importance of biophysical interactions in creating phalarope habitat, and characterized red-necked phalarope habitat in both space and time. In Onslow Bay, I investigated the effects of Gulf Stream fronts and eddies on the abundance and distribution of seabirds …
