UKHO Contracts with TCarta

TCarta Marine was contracted by the United Kingdom Hydrographic Office (UKHO) to provide a baseline dataset of water depths and seafloor classification around the Republic of Kiribati. Located in the Pacific Ocean, the island nation is threatened by rising sea levels.TCarta won the open bid for supply of Satellite Derived Bathymetry (SDB) to the UKHO to extract water depth measurements and seafloor classifications, including habitat types, from multispectral satellite imagery. In this project, TCarta is processing eight-band DigitalGlobe WorldView-2 and -3 data predominantly, as well as four-band

Regulator: Expand Pipeline, Protect Killer Whales

Canada's National Energy Board (NEB) regulator recommended on Friday that Ottawa approve expansion of the government-owned Trans Mountain oil pipeline, but made new, nonbinding recommendations to mitigate harm to Pacific Ocean killer whales and the environment.The pipeline is in the national interest as it will create jobs and give Canadian oil access to more markets, the NEB said in a report. But expanding it is likely to significantly harm the killer whale population off the coast of British Columbia and increase greenhouse gas emissions from ships, the board said in its report.It made 16 new

Tonga Cable System Repaired

and completed the necessary repairs to both cables within eight days of arrival on repair grounds. The repairs took place under the South Pacific Marine Maintenance Agreement (SPMMA), pursuant to which SubCom maintains over 69,000 km of cable consisting of 33 data and power cable systems in the Pacific Ocean.The Tonga Cable System is an international cable in the Pacific Ocean that spans 827 kilometers with landing points in Nuku’alofa, Tonga and Suva, Fiji. The Tonga Domestic Cable Extension is a 406-kilometer cable with three landing points in Tonga: Neiafu, Nukualofa and Pangai. SubCom maintains

on basic science questions supported by entities such as the National Science Foundation. He took part in iconic seagoing expeditions including the Capricorn Expedition in 1952 and 1953. For this expedition, Munk, Revelle and dozens of other scientists were dispatched to the Marshall Islands in the Pacific Ocean in the prelude to the testing of a nuclear bomb at Bikini Atoll. Munk’s concern for the potential that the detonation would trigger a tsunami led to his development of early warning methods incorporated into modern warning networks. During Capricorn, Munk was also among scientists who participat

McLane Research Announces New WTS-LV Deep Option

the recent U.S. GEOTRACES GP15 cruise. WTS-LV samplers with dual Vertical Intake filter holders are specified by the GEOTRACES program, a global effort to better understand the world’s oceans through their trace elements. Cruise GP15 was the first meridional section of GEOTRACES through the Pacific Ocean between Alaska and Tahiti.WTS-LV samplers collect a single water sample onto 142mm filter media. The Dual Filter model features separately metered, modular 142mm vertical intake filter holders for parallel filtration. In addition to the new Deep feature, other options for this single event sampler

India Plans Deep Dive for Seabed Minerals

The mission includes dives to the Puerto Rico Trench (Atlantic Ocean 8,408 meters), the South Sandwich Trench (Southern Ocean 8,183 meters), the Java Trench (Indian Ocean 7,290 meters), the Mariana Trench/ Challenger Deep (Pacific Ocean 10,925 meters), and the Molloy Deep (Artic Ocean 5,573 meters).Teledyne Bowtech have been supplying lights for Triton vehicles for many years and since became the standard fit. As a result, Teledyne Bowtech were commissioned to design a bespoke lamp, designed to operate in up to 11,000 meters

Whale Tracks Found in Areas Targeted for Deep-sea Mining

A series of depressions forming mysterious “tracks” on the seafloor may be an unprecedented record of deep-diving whales. The observations were made by an autonomous underwater vehicle (AUV) in a region of the Pacific Ocean targeted for deep-sea nodule mining, as part of a new study led by the National Oceanography Centre (NOC) and the University of Southampton.Initially perplexed by the mysterious tracks, researchers concluded they were not related to mining or scientific operations within the area; they appeared too large to be created by fish or any other typical deep-sea animals; and

Peru Will Likely Create Pacific Ocean Reserve in 2019

Peruvian President Martin Vizcarra's government is planning to create an ocean reserve in the first quarter to protect feeding and breeding grounds for humpback whales and other marine species, the environment minister said on Monday.The reserve would span more than 400 square miles (1,040 square km) and overlap with four offshore oil blocks, according to a government document on the proposal.Environment Minister Fabiola Munoz said oil drilling and fishing would still be allowed in the protected area, but that extra care would be taken to ensure they do not threaten marine ecosystems, with resources

Sea level rise is a threat to cities from New York to Shanghai as well as low-lying nations from the Pacific Ocean to the Netherlands.“We’re watching these reports closely,” said Michiel van den Broeke, professor of Polar Meteorology at Utrecht University in the Netherlands, saying they were the guide for defending the Dutch coast.Under the 2015 Paris climate agreement, almost 200 governments
