Full-Depth Current Profiling Around the Global Ocean

for knowing more about deep currents is to clarify the global thermohaline circulation. Along the western edge of all major ocean basins, narrow, swift undercurrents have been observed at depth. They have distinct water properties and flow counter to strong surface currents.Using LADCPs off southern Africa, UK scientists identified an unknown undercurrent. The substantial Agulhas Undercurrent, which surprisingly is not evident in hydro data, flows equatorward at 1200 m depth. Found alongside the continental slope, this deep current carries ten times the volume of the world’s largest river. Later

The Norwich location is the headquarters for their European, Middle East and Africa regional sales, services, and project support. Norwich also opened a dedicated data processing and offshore services center. The center provides an equipment and data processing hub located in a globally central time zone to enable better customer support with faster more efficient regional responsiveness

Thanks to a Nexans IMR agreement, a TSO could potentially cut the response time to an incident by up to 70 percent.The company has a 40-year track record, having performed more than 50 offshore repairs throughout Asia, Africa, America, Europe and the North Sea region. For instance, Nexans has been entrusted as a key partner for ensuring power supply to millions of Statnett’s end customers. With Statnett, Norwegian system operator of the energy system, Nexans today continues to develop the existing contingency agreement

CGG Releases Data from Mozambique Survey

The fast-track 3D seismic data from CGG’s recent Mozambique multi-client survey in the outer Zambezi Delta Basin is now available for license, the geoscience company announced during Africa Oil Week.The data covers a 15,400 km2 area over blocks Z5-C and Z5-D and surrounding open acreage. It was acquired as part of a multi-client program agreed between CGG and Mozambique’s Instituto Nacional de Petroleo (INP) in 2017.Interested international oil companies can view the high-end data set in CGG data rooms in anticipation of the country’s 2019 licensing round.CGG said final PSDM deliverabl

Persistent Profiling of the Greater Agulhas Current

Two Decades of Moored ADCPs off Southern AfricaFor the last two decades, the energetic and deep currents off southern Africa have seen persistent scrutiny. Found on the western edge of the South Indian Ocean, the Agulhas Current system exhibits complex circulation patterns—retroflection, meandering, and rings. They show large variability from year-to-year. Plus these flows mediate exchanges between three of the world’s major oceans: Indian, Atlantic, and Southern.Even more important, the Greater Agulhas Current is now suspected to influence the global climate system. Its role is to precondit
