Dense thickets of the reef-building coral Desmophyllum pertusum (previously called Lophelia pertusa) make up most of the deep-sea coral reef habitat found on the Blake Plateau in the Atlantic Ocean. The white coloring is healthy – deep-sea corals don’t rely on symbiotic algae, so they can’t bleach. Images of these corals were taken during a 2019 expedition dive off the coast of Florida.

These reefs were easy to quantify.Other records, including

The Curious Case of the 1,200 MW Transmission Size “Limit” in New England

up to 2,000 MW, the Boston-based Mystic Generating Station units 8 and 9, which collectively are a 1,600 MW single source loss due to a common natural gas fuel source issue from an adjacent liquefied natural gas gasification facility, and the region’s two remaining nuclear plants, Seabrook in New Hampshire and Millstone in Connecticut, can all operate above 1,200 MW and up to their limits as long as system generation dispatch and resulting power flows on the New York and PJM systems allow.  The 2016 planning process limit only applies prospectively to new resources – HVDC lines interconnectin

New Ocean Mapping Center Partnership

NOAA and the University of New Hampshire (UNH) are expanding a 24-year ocean and Great Lakes mapping partnership through the creation of a new Center of Excellence for Operational Ocean and Great Lakes Mapping.“NOAA and UNH have a long history of collaborating to advance the latest technologies and tools to map our ocean, coasts and Great Lakes — a cornerstone of the blue economy,” said Rick Spinrad, Ph.D., NOAA Administrator. “Our continued partnership on the Center of Excellence will help build a workforce ready to tackle the mapping challenges of the future, and further our

Exail and UNH Open Maritime Autonomy Innovation Hub

A new innovation hub at the University of New Hampshire (UNH) will engage in all aspects of marine autonomous operations to help meet the challenges of the growing blue economy.  High-tech industrial group Exail will use the new center to deliver increased operational advantage to U.S. civil and government customers. This includes the U.S. production of its uncrewed surface vessel (USV), DriX, the housing of a remote operation center to conduct worldwide remote autonomous operations, establishing local operations, maintenance and training facilities, and providing expertise on maritime autonomy

DriX USV Delivered to UNH CCOM

The University of New Hampshire’s Center for Coastal and Ocean Mapping (UNH CCOM), as a member of the Ocean Exploration Cooperative Institute (OECI), funded by NOAA Ocean Exploration, took delivery of an iXblue DriX Uncrewed Surface Vehicle (USV) and its Universal Deployment System. The autonomous solution will help expand the footprint and efficiency of the OECI’s ocean exploration operations. Delivered in July to UNH CCOM, DriX and its novel Universal Deployment System have completed sea acceptance trials and extensive personnel training during the summer of 2021 as well as integratio

Through the National Oceanographic Partnership Program (NOPP), a multi-year grant was provided to the University of New Hampshire, Saildrone, and the Monterey Bay Aquarium Research Institute to test and integrate acoustic and other sensors into a new larger class of uncrewed surface vehicles powered by wind and solar power. The 22m Saildrone Surveyor is designed to collect bathymetry of the seafloor, water column data,
