will provide sea floor energy storage for offshore operations.OPT's subsea battery solutions will enable the powering of subsea equipment, sensors, and communications, and the recharge of autonomous underwater vehicles (AUV) and electric remotely operated vehicles (eROV). They can power sensors, chemical injection systems, and even electric trees and control systems, which regulate the flow of oil, chemicals, and water and gas injection and disposal.According to data from Fior Research, the global subsea battery sales market is projected to grow to over $668 million over the next five years as industries

MATE At-Sea Internship Opportunity

, South Africa; and Montevideo, Uruguay (cruise plans are still in development.)Internship projects will vary from one cruise to another and correspond to the cruise objectives set by the lead scientists for each cruise. Previous interns have worked on cruises to support science projects ranging from chemical oceanography, marine biology, GIS/bathymetric surveys (seafloor mapping), geological studies, work with ROVs and much more! The position will last approximately six months and the intern will receive a stipend of $500 per week, plus reimbursement for travel expenses and housing - mostly aboard one

Hunting Hydrocarbons

Subsea gliders are taking to the oceans to hunt for an ever wider array of anthropomorphic and chemical signatures to an ever greater accuracy.Ocean glider systems are maturing. Since emerging in the 2000s, they’ve opened up new possibilities for ocean observation and monitoring. But, these possibilities are continuing to expand, including to gas seep surveys, leak detection, mammal monitoring and oil spill monitoring, for the offshore oil and gas industry.The primary attraction of ocean gliders is their ability to stay at sea for months, monitoring wide areas in remote locations down to significa

Mapping the Future

, Ph.D, Senior Director, Shell Ocean Discovery XPRIZEWhat do you hope to achieve through the Shell Ocean Discovery XPRIZE?The Shell Ocean Discovery XPRIZE aims to achieve three key goals: to accelerate technology in marine underwater robotics, especially mapping, imaging, and the autonomous detection of chemical or biological signals; to catalyze new markets by removing manned vessels and make it cheaper to access the deep sea; and finally, to inspire the public – these robots are discovering a new underwater planet with strange lifeforms and unfamiliar terrains. These exponential technologies can

part of an international collaboration.The conversion of the initial wide area survey imagery into three dimensional seafloor maps and habitat type summaries onboard Falkor, allowed the researchers to plan the subsequent robotic deployments to perform higher resolution visual imaging, environmental and chemical surveying, and physical sampling in areas of greatest interest, particularly at the ephemeral hotspots of biological activity that intermittently form around transitory methane seeps. Nineteen AUV deployments and fifteen ROV dives were completed in total during the expedition, including several
