In opening our eyes to the unseen wonders of the ocean Jacques Cousteau is thought to have said, “People protect what they love.” A variation, perhaps, on the words of the Senegalese poet and naturalist Baba Dioum: “In the end, we will conserve only what we love. We will love...
New seafloor mapping and sampling demonstrates that the eruption of the high-Ca boninites is clearly associated with rifting of the northern Tonga ridge and the northern Lau Basin at the northern termination of the Tonga Trench. There is very strong evidence for OIB plume related mantle sources involved in the...
As we contend with human impacts on the biosphere, there is rightfully a great emphasis now on community adaptation and resilience to climate change. Recent innovations in information technologies and analyses are helping communities to become more resilient. However, not often discussed in this vein is a path toward digital...
Agencies in the US with oversight for marine renewable energy development have idealistically sought space where this new use might proceed unhindered by other uses. Despite experiential evidence of spatial overlap among existing ocean uses, a lack of documentation makes the identification of potential space-use conflicts, communication among existing and...
Marine environments, key life-support systems for the earth, are under severe threat. Issues
associated with managing these common property resources are complex and interrelated.
Networks of marine reserves can be valuable for mitigating threats to marine systems, yet the
successful design and implementation of such networks has been limited. Efficient...
This perspectives paper uses the seminal Goodchild (1992) article as a lens through which to review and reflect upon several longstanding issues that have influenced the field of geographic information science in the past and will continue to be important at least into the next decade. Under the category of...
The volcanic origin of the Samoan archipelago can be explained by one of three models, specifically, by a hot spot forming over a mantle plume, by lithospheric extension resulting from complex subduction tectonics in the region, or by a combination of these two processes, either acting sequentially or synchronously. In...
The deep-towed Argo I optical/acoustical vehicle and a geographic information system (GIS) have been used to establish the abundance, widths, and spatial distribution of fissures, as well as the relative age distribution of lavas along the narrow (<500 m wide) axial zone of the East Pacific Rise (EPR) from 9°12′...
Fissure densities and widths have been mapped along the axial zone of the superfast spreading southern East Pacific Rise (EPR) at 17°15′–40′S with the near-bottom DSL-120 and Argo II imaging systems. We observe that the youngest lava flows (on a relative age scale) are sparsely fissured and that there is...
