Presently, scientific communities are confronting Earth’s foremost environmental issues using best management practices. However, an increase for need in the synthesis of socio-ecological principles using a multi- and trans-disciplinary approach is required for solutions that benefit both nature and humans. To examine whether a community perceives stormwater runoff as both a local resource and threat to coastal water quality, an online survey of the Ventura River watershed community probed local residents’ understanding of watershed knowledge, beliefs, and behavior with regards to their local environment as it pertained to water resources, especially as affected by human activity. Analysis of 144 participants’ responses and their self-reported water activity, water activity frequency, and perceptions of Ventura River’s discharge and stormwater runoff reveals the community’s behavior regarding exposure to poor water quality in a local coastal environment and, ultimately, the survey participants’ level of geoliteracy concerning their local watershed. A statistical analysis between categorical variables of the survey questions examines relationships between self-reported waterborne illness symptoms and the water activities that participants enjoy regularly and/or perform for work. The survey responses demonstrated common themes in water knowledge that exist throughout this particular coastal community. Additionally, through the use of an optical and historical classification system, the Ventura River’s sediment discharge was examined both remotely and in situ. Multispectral ocean color satellite sensors have been useful in monitoring the water quality of Case 2 waters. Particularly, after severe storm events contaminants can be carried along with storm runoff from urban storm drains and Mediterranean river mouths which then enter coastal and recreationally trafficked water. Earth scientists have observed poor water quality occurring offshore in Case 2 waters near major river mouths and urban areas causing the coastal water column to deteriorate in quality.

Karst environments are interconnected landscapes vulnerable to degradation. Many instances of anthropogenic karst disturbance are unintentional, and occur because of the public's lack of understanding or exposure to karst knowledge. When attempts are made to educate the general public about these landscapes, the concepts taught are often too abstract to be fully understood. Thus, karst educational pursuits must use only the most efficient and effective learning materials. A technique useful for assessing educational effectiveness of learning materials is eye-tracking, which allows scientists to quantitatively measure an individual's points of interest and eye movements when viewing a 2D or 3D visualization. Visualization developers use eye-tracking data to create graphics that hold the observer's attention and, thereby, enhance learning about a particular concept. This study aimed to assess and improve the educational effectiveness of 2D karst visualizations by combining eye-tracking techniques with Geographic Information Systems, knowledge assessments, and semi-structured interviews. The first phase of this study consisted of groups of 10 participants viewing 2D karst visualizations with one category of manipulated visual stimuli. The second phase consisted of groups of 10-15 participants viewing 2D karst visualizations that were created based on the results from the first phase. The results of this study highlighted both effective stimuli in karst visualizations and stimuli that hinder the educational effectiveness of visualizations.

Geoscience operates at the boundary between two worlds; the visible and the invisible. Increasingly, new geological technologies such as hydraulic fracturing, carbon capture and storage (CCS) and radioactive waste disposal are drawing the public’s attention to the ‘invisible’ world of the geological subsurface. This presents unique communication challenges because these technologies exist in a realm that can never be physically seen. This thesis addresses this issue by examining the psychological perceptions of residents in three villages in the south west of England. A representative sample from each village was qualitatively interviewed and mental models were constructed from the resultant data using the ‘mental models’ technique (Morgan et al, 2002). The mental models were then quantitatively tested using a questionnaire to assess the perceptions that a broader sample of the residents of these locations hold towards the geological subsurface. The results from the mental models assessment identified the principal perceptions held by the majority of the public surveyed. In particular, the study revealed the connection between the visible surface and the invisible subsurface and how different participants engaged with that boundary; choosing either a geoscience-centric or an anthropocentric approach to penetrating the surface. These approaches utilised by non-experts differed from those employed by the experts, who used a regionally specific geoscience-centric approach to visualising the subsurface. The work provides an important empirical baseline from which to develop a science-led strategy to engage the general public with new technologies and to increase our understanding of the more broadly held conceptions of the invisible subsurface.
