Communicating Astrobiology: Words versus Numbers, Cause versus Consequence, Fact versus Fiction Open
Recently, NASA scientists and administrators have proposed a numerical scale for quantifying the Confidence of Life Detection – the CoLD scale [1]. Although the stated goal is to minimize damaging public trust with premature or overly-conf…

Naval Ship Counter Measure Capability (Final Report) [Slides] Open
Task 1: RUNQUIC.py was modified to add options 4 and 5, which run only the QUIC-PLUME and QUICPRESSURE codes without rerunning QUIC-URB. Task 2: We have verified that the RUNQUIC.py produces a WPC file to facilitate the interface with the …

Hype, skin in the game, and the stability of cooperative science Open
We address a recently posed question: ‘Why Do SoMany Astronomy (and Astrobiology) Discoveries Fail to Live Up to the Hype?’ We expand it to cover hype within science in general. Our answer relies on working definitions of hype and skin in …

The rise of the academic science humble brag Open
One of the lesser admitted realities of academia is the need to promote one’s successes in order to curate a reputation to increase the chances of funding, promotion, and publication. This has led to the unfortunate emergence of well-inten…

The Climate of Earth and Earth-like (Exo)planets in Coupled Evolution Models: Insights from 3D GCM. Open
We investigate the past evolution of the climate of Earth and Earth-like planets as a coupled interior/atmosphere system. We compare climatic states obtained through parameterized modelling versus a physics-based 3D General Circulation Mod…

Influence of the Asthenosphere on Earth Dynamics and Evolution Open
The existence of a thin, weak asthenospheric layer beneath Earth’s lithospheric plates is consistent with existing geological and geophysical constraints, including Pleistocene glacio-isostatic adjustment, modeling of gravity anomali…

Plate Tectonics, Mixed Heating Convection and the Divergence of Mantle and Plume Temperatures Open
Petrological data indicate that upper mantle and mantle plume temperatures diverged 2.5 billion years ago. This has been interpreted as plate tectonics initiating at 2.5 Ga with Earth operating as a single plate planet before then. We take…

Internal Planetary Feedbacks, Mantle Dynamics, and Plate Tectonics Open
Isolating planetary feedbacks, and feedback analysis, are prevalent aspects of climate and Earth surface process science. An under appreciation of internal planet feedbacks, and feedback analysis for plate tectonics research, motivate this…

Deep-water cycling and the Magmatic History of the Earth Open
Earth is a magmatically active planet. Magmatism connects Earth's interior to its atmosphere, hydrosphere, and biosphere through cycling of volatiles, greenhouse gasses, and nutrients. Earth's magmatic history is intertwined with its therm…

The Temporal Onset of Habitability For Earth-Like Planets Open
The ability of a planet to maintain surface water, key to life as we know it, depends on solar and planetary energy. As a star ages, it delivers more energy to a planet. As a planet ages it produces less internal heat, which leads to cooli…

OW1 Data InOut Open
The parameter inputs and data outputs provided herein were used to establish the hypothesis that changes in deep water cycling lead to a multi-stage cooling of the Earth.

Different Is More: The Value of Finding an Inhabited Planet That Is Far from Earth2.0 Open
The search for an inhabited planet, beyond our own, is a driver of planetary exploration in our solar system and beyond. Using information from our own planet to inform search strategies allows for a targeted search. It is, however, worth …

Deep Water Cycling and Delayed Onset Cooling of the Earth Open
Changes that occur on our planet can be tracked back to one of two energy sources: the sun and the Earth's internal energy. The motion of tectonic plates, volcanism, mountain building and the reshaping of our planet's surface over geologic…
