Un-mixing the Ocean: Double Diffusion and Turbulence in Polar Oceans

, 2022
This thesis concerns theory, numerical simulations and observations of double-diffusion in polar settings. Double diffusion refers to processes occurring due to the difference in molecular diffusivities between two components that both contribute to the density.

Seasonal Variation in Carbon Dynamics in the Lower Tocantins River: Influence of Discharge and Environmental Drivers

River Research and Applications, EarlyView.
ABSTRACT Tropical rivers play a key role in regional carbon budgets, yet greenhouse gas (GHG) dynamics in regulated systems remain poorly understood. This study investigates the seasonal variability of carbon dioxide (CO2) and methane (CH4) concentrations, isotopic composition (δ13C), and river‐atmosphere fluxes in the lower Tocantins River, a ...

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Examining the Role of Economic Complexity and Climate Readiness in the Climate‐Fishing Nexus

Sustainable Development, EarlyView.
ABSTRACT This paper investigates the climate‐fisheries association in Gulf Cooperation Council (GCC) nations from 1999 to 2022. A key objective is to explore the role of both the economic complexity index (ECI) and the climate readiness factor (READ) in the climate‐fishing nexus.

Performance analysis of the OAM based optical wireless communication systems with partially coherent elegant Laguerre–Gaussian beams in oceanic turbulence

Journal of Optics, 2019
The transmission model of partially coherent elegant Laguerre–Gaussian (ELG) beams in oceanic turbulence is established by employing the spatial power spectrum of the refractive index of sea-water and the optics approximation.

Mobile consumers influence the shoreward edge of intertidal seagrass ecosystems

Journal of Animal Ecology, EarlyView.
Ecological paradigms suggest that the environmentally stressful edge of a habitat is determined by physical factors. The work finds that, counter to these paradigms, an environmentally stressful edge can also be impacted by biotic interactions and are more complex than suggested.

Chaotic Variability of Ocean Heat Content: Climate-Relevant Features and Observational Implications

Oceanography, 2018
Global ocean models that admit mesoscale turbulence spontaneously generate interannual-to-multidecadal chaotic intrinsic variability in the absence of atmospheric forcing variability at these timescales.

Remembering Interracial Intimacies: South Asian Perspectives on Black/Brown Sex and Romance in Colonial East Africa

Gender &History, EarlyView.
ABSTRACT Bringing together historical evidence, postcolonial fiction and memory work, this study recovers South Asian cultural attitudes towards interracial heterosexual romance from the margins of East African history. It asks why Black/brown intimacy was treated as taboo and denied legitimacy within South Asian diasporic communities in British‐ruled ...

MIMO techniques for robust underwater optical wireless communications by mitigating oceanic turbulence and transceiver misalignment

Scientific African
By using Binary Phase-Shift Keying (BPSK) modulation with heterodyne detection, we present in this paper an analytical approach to evaluate the effect of oceanic turbulence and pointing errors effects on an Underwater Wireless Optical Communication (UWOC)

State of the Field: Royal Studies and Court Studies

History, EarlyView.
Abstract Monarchy, as the world's oldest and most enduring form of political organization, is an area that has attracted the attention of scholars from a range of disciplines. Two connected and complementary fields embody this interdisciplinary study of monarchy and monarchies: royal studies, which takes an all‐encompassing approach to monarchy, and ...
