Experimental Validation of Melt Probe Models for the Exploration of Ocean Worlds
Ocean Worlds, where large volumes of water may exist under a layer of ice, are strong candidates for the first discovery of extraterrestrial life. Jupiter’s moon Europa is currently believed to have at least twice as much water as Earth. A key remaining challenge is developing a probe that can …

Effect of temperature-dependent ice properties on ice shell convection for icy ocean worlds
… a critical control on the habitability of icy ocean worlds. Here, we present a systematic study evaluating the effect of temperature-dependent material properties on these dynamics. We review the published thermal conductivity data for ice, which demonstrates that the most commonly used …

Planetary Seismology using Single-Station and Small-Aperture Arrays: Implications for Mars and Ocean Worlds
… results for a future surface mission to an icy ocean world. If mock-lander instruments were unprotected from the wind, noise levels were 50 dB higher than those on the ground. However, once seismometers were shielded via burial, noise performances were similar to the ground-coupled seismometers, …

Microbial communities, activities, and metabolisms in Earth’s subseafloor and analog oceanic environments
… flow, and the long-term habitability of the oceanic crust, while also offering insight into the potential for life on other Ocean Worlds. However, the functional dynamics of these subseafloor microbial communities remains unresolved. This thesis investigates how geochemical conditions shape …

Modeling Non-Rotational Ocean Circulation and Heat Distribution in Icy Moons
Subsurface oceans beneath the ice shells of icy moons like Europa and Enceladus are considered promising environments for extraterrestrial life. Their long-term habitability depends on internal heating and efficient vertical heat transport to maintain liquid water beneath the surface. This study …

What’s in a World? Economic, political and cultural convergence across the medieval western Indian Ocean.
… of the archaeology and history of the Indian Ocean littoral is often framed through the lens of the “Indian Ocean World”. This framework goes beyond the more traditional focus on political frontiers and land-based boundaries, conceptualising the sea as a sphere of connections, not as a …

Slavery and Empire in Iberian Scholastic Thought, c. 1539-1682
… slavery into the Atlantic, Pacific, and Indian Ocean worlds. When pondering whether or not a human being could be enslaved, the single most important question that Iberians intellectuals posed was whether or not the person was a fellow Christian. Where scholars have emphasized the religiously …
