Lichen photobiont diversity and selectivity at the southern limit of the maritime Antarctic region (Coal Nunatak, Alexander Island)

first_imgAntarctic ice-free inland sites provide a unique perspective on the strategies coevolving organisms have developed for survival at the limits of life. Here, we provide the first combined description of the ecological and genetic diversity of lichen photobionts colonising an isolated Antarctic inland site, Coal Nunatak, on south-east Alexander Island (Antarctic Peninsula). Photobionts of 14 lichen species (42 samples), all belonging to the group of coccal green algae, representing the entire lichen community of Coal Nunatak were investigated using the internal transcribed spacer region (ITS) of the nuclear ribosomal DNA. The study attempted to address the hypothesis that mycobiont selectivity for the photobiont partner is lower in more extreme environments. This hypothesis did not appear to hold true for the entire lichen community except one species. Another aspect focuses on the relevance of the reproduction modus concerning the distribution of photobiont haplotypes in the lichen community.last_img read more

A risk assessment framework for the socio-economic impacts ofelectricity transmission infrastructure failure due to space weather: an application to the United Kingdom

first_imgSpace weather phenomena have been studied in detail in the peer‐reviewed scientific literature. However, there has arguably been scant analysis of the potential socioeconomic impacts of space weather, despite a growing gray literature from different national studies, of varying degrees of methodological rigor. In this analysis, we therefore provide a general framework for assessing the potential socioeconomic impacts of critical infrastructure failure resulting from geomagnetic disturbances, applying it to the British high‐voltage electricity transmission network. Socioeconomic analysis of this threat has hitherto failed to address the general geophysical risk, asset vulnerability, and the network structure of critical infrastructure systems. We overcome this by using a three‐part method that includes (i) estimating the probability of intense magnetospheric substorms, (ii) exploring the vulnerability of electricity transmission assets to geomagnetically induced currents, and (iii) testing the socioeconomic impacts under different levels of space weather forecasting. This has required a multidisciplinary approach, providing a step toward the standardization of space weather risk assessment. We find that for a Carrington‐sized 1‐in‐100‐year event with no space weather forecasting capability, the gross domestic product loss to the United Kingdom could be as high as £15.9 billion, with this figure dropping to £2.9 billion based on current forecasting capability. However, with existing satellites nearing the end of their life, current forecasting capability will decrease in coming years. Therefore, if no further investment takes place, critical infrastructure will become more vulnerable to space weather. Additional investment could provide enhanced forecasting, reducing the economic loss for a Carrington‐sized 1‐in‐100‐year event to £0.9 billion.last_img read more

Fidelity of yellowfin tuna to seamount and island foraging grounds in the central South Atlantic Ocean

first_imgThe yellowfin tuna (Thunnus albacares) is a widely distributed, migratory species that supports valuable commercial fisheries throughout their range. Management of migratory species requires knowledge of movement, mixing and key life history parameters such as growth rate, natural and fisheries mortality. Current management is based on the assumptions that the species is highly migratory and populations are well mixed, but these assumptions have been questioned by recent studies. Since November 2015, yellowfin tuna have been tagged with conventional, archival and pop-up satellite tags (PSAT) in the South Atlantic Ocean around St Helena, with the goal of better understanding their movement patterns and ecology in this region. Conventional tags were attached to 4049 yellowfin tuna (size range 24–158 cm fork length, FL), PSAT tags were deployed on 15 yellowfin in inshore St Helena waters (size range 95–138 cm FL) and 7 yellowfin (size range 125–140 cm FL) at Cardno Seamount, and archival tags were deployed on 48 yellowfin tuna in inshore St Helena waters (size range 69–111 cm FL). Most yellowfin tuna remained within 70 km of their release location, suggesting a degree of retention to the region. Although displacement of yellowfin was generally low, the furthest distance travelled between release and recapture location was 2755 km, with other tuna also displaying large-scale movements. Tagging revealed connections between inshore regions and seamounts, as well as links between St Helena waters and key fishing regions and putative spawning grounds in the Gulf of Guinea.last_img read more

Norwegian PM officially opens Johan Sverdrup field in North Sea

first_img Equinor CEO Eldar Sætre marking the official opening of the Johan Svedrup field, together with Norwegian Prime Minister Erna Solberg and Oil and Energy Minister Sylvi Listhaug. (Credit: Arne Reidar Mortensen/Equinor ASA) The Johan Sverdrup field operated by Equinor in the Norwegian part of the North Sea has been officially opened by Norway’s Prime Minister (PM) Erna Solberg.Equinor and its partners Lundin Norway, Petoro, Aker BP, and Total commenced production from phase 1 of the offshore Norwegian field in October 2019. According to Equinor, production at the Johan Sverdrup project has since then ramped up to more than 300,000 barrels per day.The partners plan to begin production from the phase 2 development of the Johan Sverdrup field in the fourth quarter of 2022.Johan Sverdrup field to generate $101.7bn revenue to the Norwegian stateThe Norwegian oil and gas company expects the offshore field to generate a total production revenue of over NOK1,400bn ($158.3bn) and over NOK900bn ($101.76bn) in revenue to Norway.Johan Sverdrup is estimated to have recoverable reserves of 2.7 billion barrels of oil equivalent in place. Equinor and partners expect to produce two thirds of the oil from the offshore Norwegian field by 2030.The partners have a power-from-shore solution in place which has been designed to deliver electricity to the Johan Sverdrup project for more than 50 years. The power-from-shore solution is said to help in reducing the CO2 emissions at the Johan Sverdrup field by more than 25 million tonnes of CO2 over its lifetime.Equinor CEO Eldar Sætre said: “Johan Sverdrup offers both high value creation and record-low emissions, making Johan Sverdrup a future-oriented oil field and part of the solution for reduced emissions.“Electrification is an important tool for reaching Norwegian and international climate goals, aiming to reduce our greenhouse gas emissions in Norway by 40% by 2030, and close to zero emissions in 2050.”The Johan Sverdrup field is estimated to yield up to 660,000 barrels of oil per day in full production. Plateau production from the phase 1 development will be up to 440,000 barrels of oil per day which is likely to be achieved in the summer of 2020, said the Norwegian oil and gas company.Equinor development and production Norway executive vice president Arne Sigve Nylund said: “We are working systematically on creating higher value from the field and achieving an optimal recovery rate. The field ambition is to reach a recovery rate above 70%.” The Johan Sverdrup field is expected to generate a total production revenue of over $158.3bn, and over $101.76bn in revenue to Norwaylast_img read more

Glenfarne Group completes acquisition of Magnolia LNG project

first_imgMagnolia LNG is an 8mtpa LNG export terminal development project located on the Industrial Canal near Lake Charles in Southwest Louisiana Glenfarne Group completes acquisition of Magnolia LNG project. (Credit: Pixabay/Gerd Altmann) US-based energy and infrastructure development and management firm, Glenfarne Group has acquired Magnolia LNG through Glenfarne’s newly formed subsidiary Magnolia LNG.Magnolia LNG is an eight million tonnes per annum (mtpa) LNG export terminal development project in Louisiana, US that has already secured Federal Energy Regulatory Commission (FERC) approval.Situated on the Industrial Canal near Lake Charles in Southwest Louisiana, the 115-acre project has a long-term Lease Option Agreement in place with the Lake Charles Harbor and Terminal District.It also has permission to receive natural gas from the existing Kinder Morgan Louisiana Pipeline (KMLP) and will pretreat, liquefy and store the LNG onsite for export and domestic purpose.KMLP is interconnected with several pipeline systems, including the ANR, Transco, Columbia Gulf, TETCO, Texas Gas, and Pine Prairie pipelines to procure gas from the US Gulf Coast states.The acquisition increases Glenfarne’s LNG export capacity to about 12 mtpaUnder the transaction, Glenfarne has also acquired Magnolia LNG’s patented optimised single mixed refrigerant (OSMR) liquefaction technology.The technology is a low-cost, highly efficient process which is configured to generate lower greenhouse gas (GHG) emissions compared to other conventional LNG processes.Glenfarne founder and managing partner Brendan Duval said: “Magnolia LNG is a well-known and high-quality project to which Glenfarne brings its funding, marketing, development and construction expertise to take it to Final Investment Decision, and then construct and operate the asset.“We believe in the essential role that natural gas plays in the transition to a lower carbon world. The facility will provide clean, low-cost and reliable energy globally, and we are proud to support this critical infrastructure project.”The firm said that the acquisition increases Glenfarne’s LNG export capacity to about 12 mtpa, of which 4mtpa will come from Texas LNG Brownsville, which is a late-stage LNG export development project in Brownsville, Texas.last_img read more
