Dive characteristics of Cross Seamount beaked whales from long‐term passive acoustic monitoring at the Pacific Missile Range Facility, Kauaʻi

Marine Mammal Science, Volume 39, Issue 1, Page 22-41, January 2023., 2023
Abstract Beaked whale foraging pulses were detected on the Pacific Missile Range Facility (PMRF) off Kauaʻi, Hawaiʻi, via long term passive acoustic monitoring. The unidentified pulses do not match foraging pulses of known species on the range but are similar to the unidentified beaked whale first detected at Cross Seamount, Hawaiʻi. Although there has

Radar Characterization of Salt Layers in Europa's Ice Shell as a Window Into Critical Ice‐Ocean Exchange Processes

Geophysical Research Letters
The potential habitability of Jupiter's moon Europa has motivated two missions: NASA's Europa Clipper and ESA's JUpiter ICy moons Explorer (JUICE). Both missions are equipped with ice‐penetrating radars which will transmit radio waves into the subsurface,

Tools for Learning—Promoting Reflection for Student Teachers' Development of PCK

Journal of Research in Science Teaching, EarlyView.
ABSTRACT This paper investigates how the coherent integration of three different tools for reflection during a science methods course can contribute to student teachers' planning and enactment of science teaching, that is, their development of pedagogical content knowledge (PCK).

Variation in diurnal and nocturnal movements distances revealed in wintering dabbling ducks in the Mississippi Alluvial Valley

Wildlife Biology, EarlyView.
Movement of waterfowl during winter is central to resource acquisition and mortality avoidance, despite the imminent risk to survival and overall fitness induced by hunting disturbance and energy expenditure. Weather and other environmental conditions may influence movement by altering resource needs, in which ducks must balance the trade‐offs of ...

Active Experiments Beyond the Earth: Plasma Effects of Sounding Radar Operations in the Ionospheres of Venus, Mars, and the Jovian System

Frontiers in Astronomy and Space Sciences, 2019
The operation of powerful satellite- and rocket-born sounding radars is often accompanied by a heating/acceleration of the local electrons and ions. Intense fluxes of sounder accelerated particles were detected in Earth's ionosphere when the frequency of

The Potato Radius: a Lower Minimum Size for Dwarf Planets [PDF]

arXiv, 2010
Gravitational and electronic forces produce a correlation between the mass and shape of objects in the universe. For example, at an average radius of ~ 200 km - 300 km, the icy moons and rocky asteroids of our Solar System transition from a rounded potato shape to a sphere. We derive this potato-to-sphere transition radius -- or "potato radius" -- from
