Robotic AUV Takes on ‘Dangerous’ Arctic Mission

a clearer picture of how warming ocean properties affect the calving process.Prof Inall said: “Given the importance of Arctic glacial ice melt in terms of climate change and sea level rise, the interaction between melt water and sea water beneath glaciers is hugely understudied. We have satellite images and models that help to predict the extent of ice loss but it is extremely important to ‘ground-truth’ these predictions by investigating conditions in the field.“It would simply be too dangerous to go into such a hostile and remote environment with a boat. Not only is there

Robotic Data Help Explain Mysterious Holes

unexpected gap in Antarctic winter sea ice. It was an opportunity that came about as a result of uncanny timing and a seasoned oceanographer’s knowledge of the sea.A new study co-authored by researchers from Scripps Institution of Oceanography at the University of California San Diego combines satellite images of the sea ice cover and data collected by robotic drifters and even seals outfitted with sensors to better understand the phenomenon. The research led by the University of Washington (UW) explores why this hole appears only some years, and what role it could play in the larger ocean circulation

was supported by the Federal Fluminense University (UFF) and the Pontifical Catholic University of Rio de Janeiro (PUC-Rio).Throughout the work of monitoring the dispersion of mining sludge at sea, professor Evangelista, along with his students, updated a Facebook page - Abrolhos Sky Watch - with satellite images showing the course of the sediment plume, so that society could also be informed about the impact of the tragedy. The study highlighted that more than three years after the rupture and collapse of the Fundão dam, the environmental damage caused by the mining companies have not yet been

Australian Agency Believes it Can Locate MH370

, despite the protests of families of those onboard.   The CSIRO has previously raised doubts about the main 120,000-sq-km underwater search zone, saying it believed the plane went down to the north of it.   Its latest assertion was its most insistent yet and was based on a review of satellite images provided by the French military intelligence service and France's national space agency, CNES, which showed 70 pieces of debris with a dozen of those "probably" man-made.   "We think it is possible to identify a most-likely location of the aircraft, with unprecedented precision

BMT ARGOSS Launches Ice Charting Capability

at the Danish Meteorological Institute.  BMT’s Mark van der Putte, who took part in the training, commented, “The training has allowed us to better understand the ice regime, i.e. how ice builds up, how it moves and reacts and how it evolves during the season.  Interpreting satellite images is also a key requirement for delivering an effective output.  The ice buildup and movement is very dependent on the weather therefore our extensive meteorological knowledge and experience will help us to further improve the service we provide.”   For the past 18 years, BMT

Autonomous Marine Water Sampling Completed ‘On-demand’

preset times regardless of the route taken.   Sampling helps scientists assess the health of the world’s oceans. Harmful algal blooms can lead to fish mortality events and cause toxicity in shellfish species which, if consumed, can be dangerous to human health. Using experimental daily satellite images of a harmful algal bloom (courtesy of NEODAAS, Plymouth Marine Laboratory), Cefas scientists navigated Lyra to a small suspected bloom of Karenia sp. north of the Dogger Bank. Once in the area of the bloom, scientists monitored the near-real time data from the on-board chlorophyll sensor to

Supported by the German Aerospace Centre (DLR), the spin-off project "Drift and Noise" and the AWI sea ice group on board, he had high-resolution satellite images of the sea ice at his disposal.  Together with the captain, hey what able to use this as a basis for assesing the ice situation Effectively and choosing the easiest route through the ice.  This expedition into the southern Weddell Sea which Followed by before to eight-week geoscientific

Yukon River Charts Produced with Satellite Images

Coast Survey has issued provisional charts for barge operators and others traversing Alaska's challenging Yukon River, relying solely on satellite images to create the electronic navigational charts that only display shoreline and shoals (shallow areas). The ENCs, which display no depth soundings, will give the mariners annually updated information to help their navigation along the changeable river.   During a virtual meeting on January 6 with barge operators who requested NOAA's charting assistance, Andrew Kampia, the cartographer in charge of the project explained, "You may hear me
