Autonomous Platforms in the Arctic Observing Network

Autonomous platforms (e.g. floats, ice-based observatories, (IBOs) and gliders) can contribute scalable, flexible elements to the Arctic Observing Network (AON), providing access to remote, icecovered regions and enabling persistent, sustained sampling and broad spatial coverage of the deep basins, marginal ice zone, shallow boundaries and gateways. Floats, gliders and IBOs excel at providing y...

Observing Dark Worlds (Final Report)

Dark matter is hypothesized to account for a large proportion of the universe’s total mass. It does not emit or absorb light, making detection of this elusive matter really hard. However, this highly massive structure creates extensive spacetime warping which alters the path of light from background galaxies. As a result, the ellipticity of galaxies that is observed on earth is altered and this...

EHPnet: The Earth Observing System

Background: In 2002 we investigated an outbreak comprising 231 patients in Norway, caused by Pseudomonas aeruginosa and linked to the use of contaminated mouth swabs called Dent-O-Sept. Here we describe the extent of contamination of the swabs, and identify critical points in the production process that made the contamination possible, in order to prevent future outbreaks. Methods: Environmenta...

Observing the Carbon-Climate System

Increases in atmospheric CO2 and CH4 result from a combination of forcing from anthropogenic emissions and Earth System feedbacks that reduce or amplify the effects of those emissions on atmospheric concentrations. Despite decades of research carbon-climate feedbacks remain poorly quantified. The impact of these uncertainties on future climate are of increasing concern, especially in the wake o...
