Expedition to the Depths Of the Ocean is About to Start

A team of Australian Oceans Institute researchers are getting ready for a ground-breaking second expedition to the depths of the ocean off Western Australia (WA). The Great Australian Deep Sea Coral and Canyon Adventure is the first-ever deep-sea exploration of the Bremer and Leeuwin submarine canyon systems, south-east and south-west of Albany in WA’s Great Southern region. Led by UWA’s Dr Julie Trotter and Dr Paolo Montagna from the Institute of Polar Science (IPS) in Italy, the team has been granted a rare opportunity to launch a deep-sea remotely operated vehicle (ROV) from aboard the oceanographic research vessel RV Falkor, which...

BedMachine Will Help Reduce the Uncertainty in Sea Level Rise

Video Included
A team of glaciologists has unveiled the most accurate portrait yet of the contours of the land beneath Antarctica’s ice sheet – and, by doing so, has helped identify which regions of the continent are going to be more, or less, vulnerable to future climate warming, according to a news release of the British Antarctic Survey. Anticipated by the global cryosphere and environmental science communities, the newly released Antarctica topography map, BedMachine, and related findings were published last month in the journal Nature Geoscience. Among results of the BedMachine project are the discovery of stabilizing ridges that protect the ice flowing across the... (read more)

Icebreaker's Science Tender Sea Trials Underway

Final sea trials for the science tender of Australia’s new icebreaker, RSV Nuyina, are underway in Norway this week. Australian Antarctic Division Icebreaker Project Manager, Nick Browne, said the 10.3 metre-long vessel was uniquely designed to support scientific research in the Southern Ocean and Antarctica. "The science tender will enable scientists to undertake marine and geoscience work in open water and ice, independently or in parallel with the Nuyina’s scientific systems. The vessel is fitted with state-of-the-art equipment, including a multibeam bathymetric echo sounder to map the seafloor, a sound velocity profiler for oceanographic work, and a moon pool for...

Watch the Arctic’s Sea Ice Slowly Disappear

Video Included
According to new research, the Arctic’s oldest and thickest ice is more mobile than ice in the rest of the Arctic and is vanishing twice as fast. Researchers have identified what they’re calling the last ice area, a 2,000-kilometre stretch of ocean northwest of Greenland where the Arctic’s summertime sea ice might survive for a few more decades. As reported in Geophysical Research Letters, a biweekly peer-reviewed scientific journal of geoscience published by the American Geophysical Union, sea ice coverage in the Arctic Ocean has declined, on average, by more than one-third from 1984 through 2018. Only in two portions of... (read more)

CGG Begins New 3D Broadband Survey in Deepwater Brazil

CGG has started acquiring Nebula 3D, a new, large, long-offset BroadSeis™ survey located in the Campos and Santos Basins, offshore Brazil. With an initial focus on Brazil’s 15th License Round blocks, the data is being acquired by the Geo Caribbean and a portion of the survey will provide 3D data coverage where no other 3D data currently exists. CGG Geoscience’s Subsurface Imaging Centre in Rio will employ the latest, most advanced data processing techniques to deliver exceptional imaging of pre-salt structures in these prolific basins. Supported by Industry Funding Dechun Lin, EVP, Multi-Client & New Ventures, CGG, said: “CGG has... (read more)

Divers Find What is Thought to be the Earliest Boatbuilding Site in the World

An 8,000-year-old wooden platform has been discovered off the Isle of Wight coast near Yarmouth in the UK,  BBC News reports. The seabed where the structure was found—at a depth of roughly 36 feet—would have been dry land when the platform was built, and still connected to the European mainland. The platform sits adjacent to and may have been part of Bouldnor Cliff, a submerged Mesolithic settlement first identified in 1999, which—among a number of discoveries—has yielded what is thought to be the earliest boatbuilding site in the world. Divers from the Maritime Archaeology Trust, which oversees the site, first spotted... (read more)

Seismic Activity Data Collection on the Ocean Floor

Sponsored Article
Unlike neighbouring Japan, earthquake activity is infrequent in the peninsula area of South Korea, and those that do occur tend to be low in intensity. Typically, earthquakes in this region measure between 2.0 and 5.0 on the Richter scale[1]. The record for the quake with the highest magnitude on the Korean Peninsula stood for some time, recorded at 5.3 in 1980. This was recently overtaken by a 5.8 magnitude tremor in Gyeongju in 2016 and a 5.4 magnitude tremor in Pohang, followed soon after by a 4.8 magnitude aftershock tremor. Data on these events is collected using the existing seismological... (read more)

Next Geosolutions Sells Out the Season in the Med

Next Geosolutions, the international geoscience and offshore engineering support service contractor, has recently been awarded three marine survey contracts from three different clients to be carried out in direct continuation in the Mediterranean Sea. The projects will involve a full range of marine survey disciplines including onshore, nearshore and offshore activities, most of which will be undertaken by using ROV-mounted sensors and tools. The first one, which has just been successfully completed, encompassed multi-discipline survey tasks aimed at supporting a deep-water survey pipeline project, involving geophysical, environmental, archaeological and UXO survey and relocation activities. Eastern Mediterranean Sea The other two missions... (read more)

Study Clarifies Influence Currents in the Atlantic Ocean on Sea Level Rise

A study by the Woods Hole Oceanographic Institution (WHOI) clarifies what influence major currents in the North Atlantic have on sea level along the northeastern United States. The study, published June 13 in the journal Geophysical Research Letters, a biweekly peer-reviewed scientific journal of geoscience published by the American Geophysical Union, examined both the strength of the Atlantic Meridional Overturning Circulation (AMOC), the zonally-integrated component of surface and deep currents in the Atlantic Ocean, and historical records of sea level in coastal New England. The AMOC is characterized by a northward flow of warm, salty water in the upper layers of the Atlantic, and a... (read more)
