UK Hydrographic Office Helps Micronesian Island Chain Monitor Sea-level Rise

Video Included
The UK Hydrographic Office has handed the Republic of Kiribati Government satellite-derived bathymetry to help the island chain monitor sea-level rise and erosion, as well as develop plans to support safe navigation, the UKHO writes in its latest newsletter. The UN lists Kiribati as one of several island groups most likely to be inundated by the sea in the 21st century because of global warming, with low-lying parts of the island chain extremely vulnerable to the effects of tsunamis, tidal surges and sea-level rise. In addition to this, Kiribati has a lack of up-to-date seabed mapping data, threatening the safety... (read more)

Expedition to Research Disappearance Pilot Amelia Earhart

UNH's Center for Coastal and Ocean Mapping has developed an autonomous surface vehicle (ASV) that can explore the seafloor in waters that may be too deep for divers. Researchers from the University of New Hampshire's Marine School are part of the crew, led by National Geographic Explorer-at-Large Robert Ballard, setting out to hopefully find answers to questions around the disappearance of famed pilot Amelia Earhart.  Amelia Mary Earhart was an American aviation pioneer and author and the first female aviator to fly solo across the Atlantic Ocean. She set many other records, wrote best-selling books about her flying experiences, and was... (read more)

AML Moving Vessel Profiler to Augment NSCC’s Seafloor Mapping Work

A newly acquired AML Moving Vessel Profiler (MVP) will help Nova Scotia Community College (NSCC) develop improved methods of mapping the seafloor. With its ability to conduct real-time, vertical profiles continuously and automatically, the MVP200 is expected to improve the efficiency and quality of data collection. Looking to add ground-truthing to the process of multibeam data acquisition, AML and NSCC are working together to integrate lights and a high-resolution camera to the tow body that houses the underway profiling system’s sound velocity (SV), conductivity-temperature-depth (CTD), or multiparameter instrumentation. Ground-truthing is a critical step in validating the seafloor characteristics for interpretation of... (read more)

Satellite Information to Increase Safety and Efficiency in Maritime Operations

A German consortium has developed a service providing detailed data on sea ice in polar regions where internet connections are slow, providing electronic navigational charts for poorly surveyed waters and software solutions to support maritime decision-making with satellite data. In July 2019, the partners completed the R&D stage of the MARSAT project, funded by the German Federal Ministry for Economic Affairs and Energy. Smarter Routing in Higher Latitudes “It’s not science fiction anymore,” said Dr Lasse Rabenstein, CEO of Drift+Noise Polar Services, a company specialising in the mapping of polar ice. “Fully automated, 24/7, near real-time ice image information for polar waters...

Is the Arctic Ice Really Growing?

Completely contrary to the messages that we see every day, the ice on the North Pole would be thicker than the computer models predict. That is if we have to believe some stories. For example, this message on www.electroverse.net in which it was reported that the Kronprins Haakon, a Norwegian ice breaker, got stuck in more than three meters of ice and had to break off an expedition. his news appeared on social media and was shared worldwide.

Cubesats Allow High Spatiotemporal Estimates of Satellite-Derived Bathymetry

Cubesats allow high spatiotemporal estimates of satellite-derived bathymetry recent study by Dimitris Poursanidis, Dimos Traganos, Chrysoulakis Nektarios and Peter Reinartz on this subject shows.  High spatial and temporal resolution satellite remote sensing estimates are the silver bullet for monitoring of coastal marine areas globally. From 2000, when the first commercial satellite platforms appeared, offering high spatial resolution data, the mapping of coastal habitats and the extraction of bathymetric information have been possible at local scales. Satellite-derived Bathymetry Since then, several platforms have offered such data, although not at the high temporal resolution, making the selection of suitable images challenging, especially...
