NIWA: Slow-slip Earthquake Research Gains Momentum

, undertaken in 2017 and 2018, have allowed scientists to study New Zealand’s largest earthquake fault in hopes of learning more about slow-slip earthquakes in subduction zones worldwide.The International Ocean Discovery Program (IODP) expeditions to the Hikurangi subduction zone off the east coast of the North Island were jointly led by researchers from the National Institute of Water and Atmospheric Research (NIWA), GNS Science, the University of Texas, and the University of Auckland. This research marks the first time scientists have studied and directly sampled rocks from the source region

and energy projects."Rovco aims to continue to support both the offshore wind and broader energy sector offering Hydrographic, Operations & Maintenance and Construction support services," the company said.The office will house its operational team, while there are also plans to find an East Coast Quayside location for deployment of Rovco's equipment and technology.“This Edinburgh office represents an important and significant milestone for our company,” said Simon Miller, General Manager: “It accommodates our growing team and enables us to develop and attract additional

findings contribute valuable information for designing resilient seafloor structures that provide the communication and power supplies that underpin our daily lives. The Geological Survey of Canada supports this important work under our Public Safety Geoscience Program. In 1929 an earthquake off the east coast of Canada triggered submarine flows, which severed 12 transatlantic cables. Submarine landslides and sediment flows are also a common coastal hazard in Canada’s inlets. The deposits of such flows are often used for dating major earthquake and land flood events, and therefore understanding

First Major US Offshore Wind Farm Reaches Permitting Milestone

, which has experienced delays over concerns that its wind turbines will hurt commercial fishing. The supplemental review by the U.S. Bureau of Ocean Energy Management, announced last year, also considered the impacts of many such projects due to the growing number of offshore wind farms planned for the East Coast.The Trump administration has sought to fire up development of the nascent offshore wind industry as part of its policy to boost domestic energy production.The 800-megawatt Vineyard Wind is expected to generate enough power for more than 400,000 homes in Massachusetts. The lease area is located

Australia Pressing Yang Ming to Pay for Container Cleanup

. The Australian Maritime Safety Authority (AMSA) says it stepped in to handle the cleanup operations after the Taiwanese shipowner and its insurer Britannia P&I refused to take responsibility for retrieving the containers and associated debris that had scattered for miles along Australia's east coast. In December 2019 AMSA hired Ardent Oceania to perform the salvage work, which began April 3 and concluded on May 8.With the subsea recovery work now completed, AMSA says it intends to recover all associated costs from Yang Ming and its insurers.An investigation led by the Australian Transport

Another two boxes were lifted in the days following.The recovered containers are among more than 80 lost from containership YM Efficiency in the Tasman Sea, about 30 kilometers off Australia's east coast, in 2018. To date, 62 containers have been located on the seafloor while another 14 are still missing. Five containers were retrieved during previous recovery efforts.Salvage company Ardent Oceania has been hired to recover the remaining containers and associated debris from the seabed using the

Measuring the Hostile Ocean Beneath Hurricanes

, Slocum gliders collected subsurface data to support response work. Recent payloads have included turbulence sensors for measuring ocean mixing, bio-acoustic sensors for assessing zooplankton stocks off Antarctica, and hydrophones for near real-time monitoring of North Atlantic right whales off the east coasts of U.S. and Canada. Slocum gliders are serving new roles at Antarctic research sites as well, especially at the edge of ice sheets.Storm Monitoring GlidersFor the last decade, Slocum gliders from Teledyne Webb Research have monitored the challenging waters associated with severe storms, sending

Vineyard Wind to Miss Startup Target Over Permit Delay

that its wind turbines will impact commercial fishing and navigation. The Department of Interior has said it needs time to study the impacts of such projects, due to the growing number of offshore wind farms planned for the East Coast.Vineyard Wind had hoped to start construction last year.The 800-megawatt project would power more than 400,000 homes, making it the first large-scale offshore wind farm in the United States. Its regulatory struggles are being closely watched by competing offshore wind developers and northeastern

Study: How Changes in Shipping Patterns Affect Whales

, California, at the National Oceanic and Atmospheric Administration’s Southwest Fisheries Science Center.  There she developed models to map the spatial distribution of many ocean species, helping the U.S. Navy plan training exercises so that they minimized impacts on marine life.On the East Coast, since the Gulf of Maine is warming faster than most of the world’s oceans, whale feeding patterns and distributions are changing. As water temperatures rise, some whales are moving farther north to find food. These changes could expose them to new risks, including increased ship strike risk
