On the Observability of Oceanic Gyres [PDF]
Journal of Physical Oceanography, 2014 AbstractThis study examines the observability of a stratified ocean in a square flat basin on a midlatitude beta plane. Here, “observability” means the ability to establish, in a finite interval of time, the time-dependent ocean state given density observations over the same interval and with no regard for errors.

Observing the Oceans Acoustically [PDF]
Frontiers in Marine Science, 2019 Acoustics play a central role in humankind’s interactions with the ocean and the life within. Passive listening to ocean “soundscapes” informs us about the physical and bio-acoustic environment from earthquakes to communication between fish. Active acoustic probing of the environment informs us about ocean topography, currents and temperature, and ...

The Argo Program: Observing the Global Ocean with Profiling Floats [PDF]
Oceanography, 2009 The Argo Program has created the first global array for observing the subsurface ocean. Argo arose from a compelling scientific need for climate-relevant ocean data; it was made possible by technology development and implemented through international ...

Phase‐Pure and Size‐Tunable Tin Halide Perovskite Quantum Dots
Advanced Materials, EarlyView.A trioctylphosphine oxide modulated protocol allows for the synthesis and study of the optical properties of a broad library of tin halide perovskite quantum dots across multiple A‐ and X‐site compositions with precise size tuning while eliminating unwanted 2D phases.

Advanced Materials, EarlyView.This work investigates the heterogeneous nucleation of CsPbBr3${\rm CsPbBr}_3$ nanocrystal superlattices along the faces of 2D PEA2PbBr4${\rm PEA}_2{\rm PbBr}_4$ layered perovskite microcrystals. Core–crown and core–shell heterostructure morphologies are obtained.

Advanced Optical Materials, EarlyView.A spectral compensation strategy is introduced to overcome radical‐induced degradation of dichroic dyes during UV photopolymerization. By incorporating a complementary photochromic liquid‐crystalline dye, broadband optical attenuation is preserved without disrupting photopolymerization, enabling high‐contrast and durable dye‐doped liquid crystal ...

The Southern Ocean Observing System [PDF]
Oceanography, 2012 The Southern Ocean includes the only latitude band where the ocean circles the earth unobstructed by continental boundaries. This accident of geography has profound consequences for global ocean circulation, biogeochemical cycles, and climate.

Electrohydrodynamically Driven Broadband and Color‐Shifting in Cholesteric Liquid Crystals
Advanced Optical Materials, EarlyView.Ion‐driven electrohydrodynamic effects enable dynamic photonic bandgap modulation in cholesteric liquid crystals under low‐frequency AC driving. By regulating ion‐mediated disturbance of the helical structure, this approach produces two reversible optical responses: rapid color shifting across the visible spectrum and broadband reflection spanning the ...
