Fugro Completes Deepwater AUV Surveys for Shell in US Gulf of Mexico

Fugro has completed several high-resolution geophysical surveys in the US Gulf of Mexico for the Shell International Exploration and Production Company. The project required data collection over multiple deepwater lease blocks in the greater Perdido and Mars development areas to support clearance of potential environmental, engineering, geological and archaeological hazards ahead of planned drilling activities. As the preferred contractor for this project, Fugro deployed a Hugin autonomous underwater vehicle (AUV) from its purpose-built survey vessel, the Fugro Brasilis. The Hugin AUV is depth-rated to 3000m and equipped with a multibeam echosounder, side-scan sonar and sub-bottom profiling sensors. As such, Fugro... (read more)

Satellites Record Second Lowest Arctic Sea Ice Extent Since 1979

The polar oceans are among the most rapidly changing oceans in the world. The yearly cycle of the build-up and melting of Arctic sea ice is one of the Earth’s vital signs and a key climate variable monitored by scientists. While they may be far from the world’s major population centres, changes in the polar regions have global implications: they affect the world’s climate through carbon storage and/or release, heat balance, and other environmental and ecological impacts. One of the most visible indicators of this change is the reduction in the extent of Arctic sea ice by the end of... (read more)

MacArtney Supports Arctic Research Expedition with Underwater Ice Camera

As the world steps up environmental awareness, the RV Polarstern is preparing for a year-long stay in the Arctic ice drift, and MacArtney Germany is playing a small part. The company has recently designed and delivered an underwater ice camera system for the research vessel, the Polarstern, a German icebreaker embarking on a global climate mission to investigate and research previously inaccessible regions during an Arctic winter. The MOSAiC International Arctic Drift Expedition, led by the German-based Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, will collect vital data on climate change over the course of the year. With a total of... (read more)

MBES-training Using a Remotely Operated USV

Swathe Services, a Hydrographic survey support company in Hayle, Cornwall (UK) ran the world’s first Multi-Beam Echo-Sounder training course using a remotely operated Unmanned Surface Vessel. People came from as far afield as Norway, France, Slovenia, UK and the USA to attend the intensive 5-day course. As part of the training, the delegates mapped Hayle Harbour in Cornwall using an Unmanned Surface Vessel fitted with Multi-beam Echo-Sounder technology. The USV was remotely operated from Swathe Services offices nearby using dedicated survey data acquisition software from HYPACK. Hands-on Training Kordula Schwarzwalder, a Researcher from the Norwegian University of Science and Technology,... (read more)

Guidelines for Monitoring Plastics in the Oceans

A new set of publicly available guidelines for monitoring plastics and microplastics in the oceans will help harmonize how scientists and others assess the scale of the marine plastic litter problem. The guidelines cover what to sample, how to sample it and how to record and assess plastics in the oceans and on the shoreline, including establishing baseline surveys. They include recommendations, advice and practical guidance for establishing programmes to monitor and assess the distribution and abundance of plastic litter, also referred to as plastic debris, in the ocean. Definitions for Categories The guidelines, published by GESAMP, include common definitions... (read more)

How Much Fishing Gear is Lost at Sea?

Abandoned, lost or otherwise discarded fishing gear or ‘ghost gear’ contributes substantially to global marine pollution, responsible for wide-reaching environmental and socioeconomic impacts. Until now, there has not been a clear global picture of the quantity and type of fishing gear lost worldwide. Using data from 68 studies published between 1975 and 2017, researchers have produced the first global estimate of commercial fishing gear losses in our oceans. “The study estimates that 6% of all fishing nets, 9% of all traps, and 29% of all lines are lost or discarded into our oceans each year,” explains Kelsey Richardson, a PhD...

USV Completes First Autonomous Circumnavigation of Antarctica

High-quality and Reliable Data Is Needed for Research Use
A 7m (23ft) long, wind-powered unmanned surface vehicle (USV) has become the first unmanned system to circumnavigate Antarctica. Known as SD 1020 and equipped with a suite of science-grade sensors, the vehicle collected data in previously uncharted waters, enabling new key insights into ocean and climate processes.

Known as SD 1020 and equipped with a suite of science-grade sensors, the vehicle collected data in previously uncharted waters, enabling new key insights into ocean and climate processes. USV SD 1020 left for the 196-day mission from Southport in Bluff, New Zealand, on 19 January 2019. It returned to the same port on 3 August after sailing over 22,000km (13,670 miles or 11,879 nautical miles) around Antarctica. During the mission, the vehicle survived freezing temperatures, 15m (50ft) waves, 130km/h (80mph) winds... (read more)

How Will First Responders Deal With Oil Trapped Under Ice?

Video Included
As sea ice continues to melt in the Arctic and oil exploration expands in the region, the possibility of an oil spill occurring under the ice is higher than ever, says the Woods Hole Oceanographic Institution (WHOI).  But how first responders will deal with oil trapped under ice in such an extreme and remote environment is a huge, unresolved question. “With the opening of the Northwest Passage a few years ago and more commercial ships routinely travelling through the area, there have been concerns among various government agencies that there’s no real infrastructure in place to respond to an oil...
