, helped attach identification tags to the turtles, and recorded and measured their shell lengths and widths as the turtles crossed the sandy beach to nest. This year is the fourth time since 2016 that NYK has sponsored this activity.As a new approach, two loggerhead sea turtles were equipped with an Argos GPS beacon for tracking, especially their coastal movement during spawning. The two loggerhead sea turtles have been named “Umi-chan” and “Hana-chan,” and their locations are provided on the in-house portal site along with comments by the project's chief researcher, Yoshimasa

and Navigator) from University of New Hampshire’s Center for Coastal and Ocean Mapping. BEN is a state-of-the-art robotic vehicle that looks like a small yellow boat. Unlike most boats, though, it doesn’t carry people; instead, it is piloted by crew members back on shore. Using sonar and GPS, BEN collects data about the lake bottom that can be used to create high-resolution maps. The expedition in Thunder Bay National Marine Sanctuary also served as a test case, helping engineers improve BEN for future uses.Researchers aboard the R/V Storm, operated by NOAA Great Lakes Environmental Research

with speed range from 2 to 8 knots and its robustness allows it to dive over 300 meters, the manufacturer said,Several AUVs can maneuver in swarm (+10) thanks to acoustics; beacons on the surface could also be used for real-time repositioning. Navigation is accurate thanks to integrated INS along with a GPS and a flasher in the mast for smooth recovery

vehicles.In order to minimise environmental impacts and nuisance to local residents, Geofizyka Toruń has implemented an innovative nodal seismic data acquisition system. It is based on an ultra-lightweight, autonomous measuring unit – a node equipped with integrated seismic data logging systems, GPS and efficient batteries durable enough for several weeks of data recording.Devoid of cables, the nodes can be easily hidden under a thin layer of soil and monitored with the use of smartphones. This novel approach, called ‘lightweight seismic surveying’, enables contractors to use more

in a measured frame to give scale to what is being filmed on the seafloor.  There must be adequate light and resolution to not only characterize the sediment type but to also positively identify flora and fauna to a scale of 1cm. The DV-2 underwater video footage complete with the date-timestamp and GPS overlay is especially critical to our surveys.  The geo-referenced data inputs into a complex model that predicts the depositional contours of the aquaculture operation as well as a comprehensive Habitat Map of the seafloor. All of this data, along with the video footage, is included in

As a consequence Güralp and Sonardyne are confident that closer

Data gathered by the new observatory will play a critical role in informing assessments of earthquake and tsunami risk to the large populations of the Pacific North-West

as a versatile vehicle that easily pairs with a variety of accessories. This particular model will be equipped with a handheld pendant controller, and a fiber optic tether multiplexer upgrade. These will help control a wide array of on-board instrumentation such as USBL underwater positioning system with GPS integration, the ROV to be tracked in real-world coordinates in real time, and an integrated Tritech Micron Echosounder which permits the ROV to measure its height above the seafloor and maintain its height with our auto-altitude system. This vehicle will also come with a dual function gripper, a

the planet’s sea floorsMany unknown landscapes in our planet are under oceanic waters. Nowadays, sea floors and polar regions build up two big frontiers for research in the field of Earth Sciences. In this context, the application of advanced technologies in scientific campaigns – differential GPS, high resolution multibeam bathymetry, 2D and 3D reflection seismic imaging, remotely operated underwater vehicle (ROV) – was a methodological revolution that broadened the precision of bathymetry maps in sea floors.The INBIS channel is located in the northern western side of the Barents Sea
