No full textCAGE13-4 Cruise Report: Sub-seabed CO2 Storage: Impact on Marine Ecosystems (ECO2) (A 7th Framework Programme EU project) PART II.
No full textCruise CAGE 13-4 focused on the acquisition of acoustic data in two of the main target areas within CAGE, the deep (>1000 m water depth) seeping Vestnesa Ridge area and the shallower (< 400 m) highly active Prins-Karls Foreland (PKF) sites. Scientific problems that are to be addressed in these two key target areas include the periodicity of seepage (i.e. time scales of active, inactive and reactivated systems), quantification of gas and hydrates, the nature of gas sources, trigger mechanisms for seepage and the architecture of the fluid flow structures underlying seafloor seepage sites.
Specific objectives of the cruise were as follows:
To repeat a P-cable survey covering the active seeps on the Vestnesa Ridge in order to develop time-lapse 4D seismic studies of gas leakage.
To acquire a P-cable survey at the active seeping area offshore PKF for planning and re-evaluation of drilling sites during the upcoming MeBo cruise in 2014.
To repeat hydro-acoustic surveying for monitoring of flares in PKF active area.

CAGE13-5 Cruise Report: Investigation of glacial geomorphology in the Storfjordrenna.
No full textThe course GEO‐8144/3144 Marine geology and geophysics cruise, taught at the University of Tromsø, is part of the obligatory courses to be completed by PhD students affiliated with the AMGG research school and yields 5 credits (ECTS). Participants include scientific staff and students.
This cruise was conducted within the framework of
the Norwegian Science Council (NFR) project Glaciations in the Barents Sea area (GlaciBar) and
the trainee school in Arctic Marine Geology and Geophysics (AMGG) financed by the University of Tromsø. The cruise was funded by AMGG.
The main target areas are the Storfjordbanken and Storfjordrenna south of Svalbard. The cruise addressed marine glacigenic processes of the areas, with a focus on the last glacial-interglacial cycle in order to reconstruct in a more detail way the retreat of the Barents Sea–Svalbard Ice Sheet.
To collect data have been used different methods and instruments, which will be described in a more detailed way in chapter 3. Below here there is only an overview:
Multibeam echo sounder: Sound-wave beams are transmitted in a fan perpendicular to the ship track from a hull-mounted echo sounder. Produces high-resolution seafloor bathymetry.
Chirp: High-resolution acoustic profiling.
CTD (Conductivity, Temperature, Depth): Sensors installed in a frame measure CTD properties of the water column. Generally used for oceanographic studies, but here mainly to calibrate the multibeam data from calculated velocities.
2D seismic: GI airguns and hydrophone cable (streamer).
Sediment coring: Gravity coring.
Gas sample collection.
The targeted study area is under-explored compared to similar areas (Bjørnøyrenna) in the SW Barents Sea. The study areas in the Storfjordrenna and Stordfjorbanken are shown. Several different features have been identified on the seafloor, like MSGLs, grounding zone wedges, flares, pockmarks and ploughmarks. All these features will be described in detail in chapter 4.
In addition, 9 gravity cores were acquired in areas likely to provide information on the timing of the formation of the sediment accumulation. The specific core locations were chosen based on information from multibeam swath bathymetry and chirp data. Furthermore, gas samples were collected from the cores from pockmarks and will be analyzed later.
The new results add new detailed data regarding the deglaciation of the Storfjorden trough. Glacial geomorphologic features similar to the ones in Bjørnøyrenna were discovered. The observation of gas flares were the first such discovery in the northern Barents Sea. The discovery of flares and pockmarks might have a big impact on future petroleum exploration activities in the region.

CAGE20-5 Cruise Report: Tectonic stress studies and seismic surveys on the West-Svalbard margin
No full textTha main goal of CAGE20-5 cruise was to continue with an Ocean Bottom Seismometer (OBS) experiment to address objectives of the SEAMSTRESS project (Tectonic stress effects on Arctic methane seepage[SB1] ). Along the eastern segment of Vestnesa Ridge, the cruise recovered 7 OBS after a one-year deployment and subsequentially redeployed 10 OBS in the larger array on the southern flank of Vestnesa Ridge. The overall aim is to detect local and regional earthquakes that relate to and/or impact local faulting within Vestnesa Ridge and may control fluid flow. Another objective of CAGE20-5 was to collect seismic lines to complete the data base and refine site selections for the IODP985 proposal. We also collected a 3D seismic volume on the elongated depression north of Knipovich Ridge where massive gas hydrates and pore fluid pressure pulses from piezometer data have been observed

CAGE16-5 Cruise Report: ROV-based Geological and Biological Investigations of Methane Seeps at Prins Karls Forland, Storfjordrenna Pingos and Bjørnøyrenna Craters
No full textThe cruise was an activity in of the Centre of Excellence for Gas Hydrate, Environment and Climate (CAGE) at UiT – The Arctic University of Norway.
The overall aim of the cruise was to utilize the NTNU/AMOS SK30k ROV for seafloor mapping and targeted sample collection at selected CAGE sites, focusing on methane seepage areas west and south of Svalbard.
More specific objectives of the cruise were to:
Use an ROV-mounted multibeam system to acquire very high resolution (10cm) seabed bathymetry in areas of methane seepsConduct detailed visual seabed surveys for habitat mapping and photomosaicking at specific seep featuresCollect seabed samples of authigenic carbontate crusts, sediments, microbes, foraminifera and macro organisms associated with methane seeps from the ROV, and complimented with more traditional sampling methodsContinue time series investigations of water column measurements of methane concentrations, and of methane oxidizing microbes in the seawaterNet sampling for planktic forams at seeps
Sampling activities were designed with a multi-disciplinary approach, with research groups from all CAGE work packages working together in the same locations to develop a holistic understanding of the geological, oceanographic and biological components at key methane seep sites. This cruise prioritized the acquisition of information for mapping seabed features and habitat characterizations (e.g. photomosaicking, visual information) combined with in-situ site sampling using ROV technologies, and complimented by our ‘traditional’ technologies (e.g. CTD, net, and coring devices).
With these objectives in mind, the strategy for each of the selected locations is to first carry out visual survey work to acquire framework measurements and data to be of use for all groups within CAGE, followed by a consolidated sampling plan to satisfy the needs of individual researchers for sample material

Fancies explained: Converting symbolic capital into NFTs
No full textThe concept of symbolic capital, introduced by Pierre Bourdieu (1986), has been applied to explain the circulation of value between game communities and the industry. The bottom-up approach can be found in the studies of so-called “gaming capital” accumulated by gamers (Consalvo, 2009), while the top-down approach focuses on the agents who hold the most power in the gaming industry (Nichols, 2013). These perspectives may require reconfiguration today: since the end of the 2010s, traditional power relations have been contested by ‘decentralized’ gaming that uses blockchain technologies and non-fungible tokens (NFTs). Their early adopters suggest that NFTs may disrupt traditional circulation of value to the benefit of players as opposed to major corporations. Many gamers, however, vehemently oppose NFTs in games. By combining these top-down and the bottom-up approaches, this article explains that the specific symbolic gaming capital remains systematically underappreciated in blockchain gaming, which operates along different vectors of power. To support my argument, I turn to the longest-running blockchain-based game CryptoKitties (Axiom Zen, 2017), and analyze the elements of the role-playing genre that appeared in the game during the collective process of continuous development. In the first case, these elements (‘fancies’) were added by the developers of the game, and in the second case, an RPG-like extension emerged as one of its fan spin-offs (KotoWars). I conclude that symbolic capital is community-specific in the case of blockchain gaming. It is only available to those who already possess considerable symbolic, and, much more importantly, financial capital within the crypto community
