OSIL Reports Export Milestone

challenging climate, the company says.The 105th export country was Georgia with an order for Niskin Bottles and a Marine Nutrient Standards Kit shipped to an oceanographic laboratory for water quality monitoring. Other recent export sales include a 30m Giant Piston Corer system to Korean Institute of Ocean Science & Technology (KIOST) for its ongoing sediment sampling program; P-Series IAPSO Standard Seawater for precise salinity measurement and high-end instrument calibrations to Morocco; two 0.6m Inshore Monitoring Buoys for remote collection of tide data to a survey company in Singapore and Nutrient

iXblue Equips Ifremer's New 6000m AUV

iXblue reports it has been chosen by Ifremer, the French National Institute for Ocean Science, to equip its new 6,000-meter-rated autonomous underwater vehicle (AUV) for the CORAL Project. The AUV will be equipped with synthetic aperture sonar (SAS), Sams-150, a Phins C7 Inertial Navigation System (INS), a sub-bottom profiler Echoes 5 000 and will use iXblue’s Delph Software suite for SAS and navigation post-processing.The “Constructive Offshore Robotics ALliance” CORAL project aims at developing, in an industrial alliance led by Ifremer, a deep sea AUV - Autonomous Underwater

BIOS: North Atlantic Carbon Sink Shrinking Due to Warming

water masses has made it clear that the effects of a warming planet extend beyond biology—they impact the physics of ocean circulation, too. The research, recently published in Nature Climate Change, was conducted by scientists from the University of British Colombia, the Bermuda Institute of Ocean Sciences (BIOS), the French Institute for Ocean Science at the University of Brest, and the University of Southampton.One particular layer in the North Atlantic Ocean, a water mass called the North Atlantic Subtropical Mode Water (STMW), represents around 20% of the entire carbon dioxide uptake in the

NOAA, Vulcan to Explore and Map the Deep Ocean

.Both NOAA and Vulcan share a mission to advance the public’s understanding of the value and importance of the global ocean. Through a new memorandum of understanding, NOAA and Vulcan intend to deepen their current work together through additional collaborative opportunities.“The future of ocean science and exploration is partnerships,” said retired Navy Rear Admiral Tim Gallaudet, Ph.D., assistant secretary of commerce for oceans and atmosphere and deputy NOAA administrator. “NOAA is forging new collaborations, such as the one with Vulcan, to accelerate our mission to map, explore

Simmons. “Through innovation we can help unlock the potential of the ocean to provide both energy and water across the country.”The DISCOVER stage, first announced at the White House Ocean Science and Technology Summit in November 2019, cast a wide net to attract concepts across five ocean observing themes: unmanned vehicles; buoys, floats, and tags; ocean communications and underwater navigation; extreme environments; and “blue sea” ideas, for entries that don't fit neatly

Environmental DNA Emerging in the Ocean Science Community

There is a new buzzword in the ocean science/sensing community. The word is eDNA, an abbreviation for environmental DNA. This refers to DNA that can be extracted from environmental samples without first isolating any target organisms. In the maritime community such samples are taken from water.  All living organisms leave traces of DNA in their environments which is an indicator of their presence over time. This DNA is released into the environment through the biological process of living animals or by the decomposition of dead organisms. eDNA is a complex mixture of traces that enables the
