A joint inversion of receiver function and Rayleigh wave phase velocity dispersion data to estimate crustal structure in West Antarctica

first_imgWe determine crustal shear-wave velocity structure and crustal thickness at recently deployed seismic stations across West Antarctica, using a joint inversion of receiver functions and fundamental mode Rayleigh wave phase velocity dispersion. The stations are from both the UK Antarctic Network (UKANET) and Polar Earth Observing Network/Antarctic Network (POLENET/ANET). The former include, for the first time, 4 stations along the spine of the Antarctic Peninsula, 3 in the Ellsworth Land and 5 stations in the vicinity of the Pine Island Rift. Within the West Antarctic Rift System (WARS) we model a crustal thickness range of 18-28 km, and show that the thinnest crust (∼18 km) is in the vicinity of the Byrd Subglacial Basin and Bentley Subglacial Trench. In these regions we also find the highest ratio of fast (Vs = 4.0-4.3 km/s) (likely mafic) lower crust to felsic/intermediate upper crust. The thickest mafic lower crust we model is in Ellsworth Land, a critical area for constraining the eastern limits of the WARS. Although we find thinner crust in this region (∼30 km) than in the neighbouring Antarctic Peninsula and Haag-Ellsworth Whitmore block (HEW), the Ellsworth Land crust has not undergone as much extension as the central WARS. This suggests that the WARS does not link with the Weddell Sea Rift System through Ellsworth Land, and instead has progressed during its formation towards the Bellingshausen and Amundsen Sea Embayments. We also find that the thin WARS crust extends towards the Pine Island Rift, suggesting that the boundary between the WARS and the Thurston Island block lies in this region, ∼200 km north of its previously accepted position. The thickest crust (38-40 km) we model in this study is in the Ellsworth Mountain section of the HEW block. We find thinner crust (30-33 km) in the Whitmore Mountains and Haag Nunatak sectors of the HEW, consistent with the composite nature of the block. In the Antarctic Peninsula we find a crustal thickness range of 30-38 km and a likely dominantly felsic/intermediate crustal composition. By forward modelling high frequency receiver functions we also assess if any thick, low velocity subglacial sediment accumulations are present, and find a 0.1-0.8 km thick layer at 10 stations within the WARS, Thurston Island and Ellsworth Land. We suggest that these units of subglacial sediment could provide a source region for the soft basal till layers found beneath numerous outlet glaciers, and may act to accelerate ice flow.last_img read more

Nordex brings the Industrial Internet of Things (IIoT) to the wind farm

first_imgIn order to keep the cost of energy as low as possible, each individual turbine is constantly adjusted by the SCADA system for interaction with other turbines in the wind farm, the ongoing wind data processed in real time, as well as the local grid conditions Image: The Nordex Group will equip the first wind farms with Nordex OS SCADA EDGE in 2020. Photo: courtesy of Nordex SE. The management and visualisation software (SCADA) is a key component of wind turbine generators. The system controls and manages the wind turbines and the wind farm in order to ensure a maximum yield. With Nordex OS™ SCADA EDGE the Nordex Group now offers the next generation of their operations control system on the basis of a virtual, hardware-independent automatic solution. Nordex OS™ SCADA EDGE is based on an IIoT (Industrial Internet of Things) platform jointly developed with Software AG and its Cumulocity IoT solution.In order to keep the cost of energy as low as possible wind farms have to be operated at the best possible performance and availability levels. This can be achieved when each individual turbine is constantly adjusted by the SCADA system for interaction with other turbines in the wind farm, the ongoing wind data processed in real time, as well as the local grid conditions. These standard conditions are fulfilled by the current proven Nordex Control 2 SCADA system. In addition to this, the new Nordex OS™ SCADA EDGE offers the possibility of accessing and displaying more data as well as including other components of the wind farm – such as the substation or battery storage. As this is a virtual solution, the new SCADA system can also be applied to other wind farm components to be added later. It is fully hardware-independent and thus future-proof as it also operates on future generations of server hardware.With the standard IIoT platform data and processes can be used both centrally and decentral. As an “on-premise solution“, Nordex OS™ Control Center is used to collect all data worldwide centrally in Hamburg, Germany.For example, the Nordex OS™ Control Center can automatically check the parameters of each individual turbine and each connected wind farm component for plausibility.Optional multiply redundant systems ensure that the Nordex Group has an availability of 99.9% for the Nordex OS™ SCADA EDGE. The system stores data for up to five years. Parallel servers ensure interruption-free operation without data loss in the event of the outage of a complete server unit.The Nordex Group offers the Nordex OS™ SCADA EDGE for its turbines of the Delta and Delta4000 series and it can also be used for older turbine generations. The Nordex Group will equip the first wind farms with Nordex OS™ SCADA EDGE in 2020. Source: Company Press Releaselast_img read more
