Scientists Study Largest Underwater Volcanic Eruption

;It turned out that each bump was a giant block of pumice, some of them the size of a van. I had never seen anything like it on the seafloor.”   Havre is part of the Kermadec Arc, a chain of volcanoes, some of which reach the surface to form the Kermadec Islands, between New Zealand and American Samoa. The volcanoes are formed by conditions at the subduction zone where one of Earth’s largest tectonic plates, the Pacific Plate, dives beneath the Australian Plate.   Scientists from New Zealand had previously mapped the Havre volcano, a caldera nearly 4.5 kilometers across on the

Wave Glider to Help Protect Marine Sanctuaries

New solutions to help protect and preserve the Hawaiian and American Samoa marine sanctuaries and monuments will be developed through a multi-year agreement between Liquid Robotics and NOAA’s Office of National Marine Sanctuaries (ONMS) Pacific Islands Region (PIR).   At the core of the long-term environmental monitoring and surveillance of the Pacific’s most diverse and endangered underwater ecosystems will be Liquid Robotics’ Wave Glider, an autonomous surface ocean robot that will be used to help address long-term monitoring and scientific data collection gaps that are not

The carrier-neutral cable system was co-developed by New Zealand-based entrepreneurs Sir Eion Edgar, Malcolm Dick and Remi Galasso as the highest cross-sectional capacity link between the U.S. and Australia and New Zealand.   For

Arizona State University ($195,837) will use a risk assessment framework to quantify microplastics (plastic pieces <5mm in size) in water, sediment and bivalves at three sites in American Samoa, and assess the types and concentrations of organic contaminants in those microplastics.   The University of Connecticut ($257,531) will identify what effects microplastic consumption has on oysters, what types of microplastics are most likely to be consumed by oysters, and increase

The GFOE has undertaken its first cruise of 2017, which set sail Feb. 16-, and runs through March 2, in support of the National Oceanic & Atmospheric Administration’s (NOAA) American Samoa seamounts expedition. This cruise kicks off the third and final year of NOAA’s exploration of U.S. Central Pacific waters.   On board the NOAA Ship Okeanos Explorer, GFOE’s team of 15 highly talented engineers and videographers are helping to investigate and document the diversity

While this year’s dives will focus on waters of the United

Hawaiki will link Australia and New Zealand to the mainland United States, as well as Hawaii and American Samoa, with options to expand to several other South Pacific islands.   Hawaiki Cable Updates SubCom has completed the route survey for the entire Hawaiki system, including the small boat, shallow water work for all landings.

The Hawaiki marine route survey is ongoing, with highlights including completion of deep sea survey from Oregon to Hawaii; survey has covered all of U.S. Exclusive Economic Zone (EEZ), with the completion of the branch to American Samoa; and progress through the South Pacific Islands continues unabated.   Hawaiki has also added three additional branching units to enable the future connection of New Caledonia, Fiji and Tonga.   In September 2016, Hawaiki Submarine Cable LP officially submitted for a submarine cable
