    Description: Foraminifera in sediments exposed to gas-hydrate dissociation are not expected to have cellular adaptations that facilitate inhabitation of chemosynthesis-based ecosystems because, to date, there are no known endemic seep foraminifera. To establish if foraminifera inhabit sediments impacted by gas-hydrate dissociation, we examined the cellular ultrastructure of Melonis barleeanus (Williamson, 1858) from the Vestnesa gas hydrate province (Arctic Ocean, west of Svalbard at ~79 °N; ~1200-m depth; n = 4). From sediments with gas hydrate indicators, living M. barleeanus had unusual pore plugs composed of a thick, fibrous meshwork; mitochondria were concentrated at the cell periphery, under pore plugs. While there was no evidence of endosymbioses with prokaryotes, most M. barleeanus specimens were associated with what appear to be Type I methanotrophic bacteria. One foraminifer had a particularly large bolus of these microbes concentrated near its aperture. This is the first documented instance of bona fide living M. barleeanus in gas-hydrate sediments and first documentation of a foraminifer living in close association with putative methanotrophs. Our observations have implications to paleoclimate records utilizing this foundational foraminiferal species.
    Description: JMB was funded by a WHOI Independent Study Award (Mellon Grant), with partial support from NSF grant OCE-1634469. GP and CAGE 15-2 cruise were supported by the Research Council of Norway through CAGE Center for Excellence in Arctic Gas Hydrate Environment and Climate project 223259 and NORCRUST (project number 255150).

    Description: Field-based classes in geological sciences are crucial components of geoscience education and research. Owing to the COVID-19 pandemic, such activities became problematic due to limitations such as travel restrictions and lockdown periods: this motivated the geoeducational community to tailor new ways to engage people in field activities. As a result, we adopted Immersive Virtual Reality as a tool to involve students, academics, and the lay public in field exploration, thus making geological exploration accessible also to people affected by permanent or temporary motor disabilities. In particular, we evaluated how users perceive the usefulness of this approach as applied to Earth Science learning and teaching, through nine outreach events, where a total of 459 participants were involved, with different ages and cultural backgrounds. The participants explored, in an immersive mode, four geological landscapes, defined as virtual geological environments, which have been reconstructed by cutting-edge, unmanned aerial system-based photogrammetry techniques. They include: Santorini (Greece), the North Volcanic Zone (Iceland), and Mt. Etna (Italy). After the exploration, each participant filled in an anonymous questionnaire. The results show that the majority would be willing to repeat the experience, and, most importantly, the majority of the students and Earth Science academics who took part in the navigation confirmed the usefulness of this technique for geo-education purposes. Our approach can be considered as a groundbreaking tool and an innovative democratic way to access information and experiences, as well as to promote inclusivity and accessibility in geo-education, while reducing travel costs, saving time, and decreasing the carbon footprint.
