Earth science in New Zealand science centres - learning aspects through a simulation based experience
… investigated how simulations at the New Zealand earth science exhibition Earthworks could teach geological concepts. The introduction of a geoscience component in the New Zealand science curriculum, the development of science-technology centres and a funding opportunity provided the incentive for …

Methods metadata: curating scientific research data for reuse
… practices for data production conducted in the Earth Sciences can provide information about data that can be used for metadata description. The research methods implemented by scientists are an essential part of the data generation process and are important for metadata inclusion. Using a case …

A Melting Fossil: Constituting Planetary Time In The Cryosphere, 1815-1980
… to understand the deep past and future of the Earth. Using archival sources that span two centuries and three continents, this project argues that through ice, Earth scientists have refashioned their conceptualization of deep time from something slow, lumbering, and uniform to something much …

Adaptive sampling of transient environmental phenomena with autonomous mobile platforms
In the environmental and earth sciences, hypotheses about transient phenomena have been universally investigated by collecting physical sample materials and performing ex situ analysis. Although the gold standard, logistical challenges limit the overall efficacy: the number of samples are limited …

Learning the dynamics of deformable objects and recursive boundary estimation using curve evolution techniques
… Some motivating applications come from the earth sciences and medical imaging. In particular, we examine the problems of oceanic front and sea surface temperature estimation in oceanography, soil boundary and moisture estimation in hydrology, and left ventricle boundary estimation across a …

Geochemical signals of volcanic unrest at the Virkisjökull Glacier Iceland
… them remains a significant knowledge gap in the earth sciences. Using Virkisjökull glacier in south east Iceland as a case study, a geochemical approach is taken to this problem by utilising stable isotopes of water and sulphate alongside major chemistry and the noble gases. Analysis of oxygen …

Rare Earth: Gemstones, Geohistory, and Commercial Geography c. 1600-1750
… methods for understanding the composition of the earth. The techniques for mapping and exploiting the world's mineral resources first developed through cross-cultural commerce would become central to the geosciences as they were formalized in the late eighteenth and early nineteenth centuries. By …

Campaign-level science traceability for Earth observation system architecting
The Earth Sciences Decadal Survey of 2007 presented a comprehensive vision for the evolution of space-based Earth Science resources. The practical development of the Decadal campaign, however, has highlighted four challenges to the original plan: the growth of expected costs and the reduction of …

A Roughness Correction for Aquarius Ocean Brightness Temperature Using the CONAE MicroWave Radiometer
… is a joint NASA/CONAE (Argentine Space Agency) Earth Sciences satellite mission to measure global sea surface salinity (SSS), using an L-band radiometer that measures ocean brightness temperature (Tb). The application of L-band radiometry to retrieve SSS is a difficult task, and therefore, …

Global investigation of large earthquakes using long-period seismic data
Robust earthquake source models provide key information for a wide range of applications in Earth Sciences, such as in global tectonics, natural hazards and tomographic studies. In this thesis, we study large magnitude earthquakes using the Earth’s normal modes, which are standing waves resulting …
