The resulting bathymetric data had a point spacing of 10 meters with measurements to a depth of 15 meters.This process, according to TCarta CEO David Critchley, saves time and money.“Our processing team delivered the satellite derived bathymetry just a

Microsatellites Launched for Maritime Monitoring, Comms and Science

 The Space Flight Laboratory (SFL) announced the successful launch of two Norwegian microsatellites developed and built by SFL for the Norwegian Space Centre with support from the Norwegian Coastal Authority, Space Norway and the European Space Agency. The Soyuz-2.1a rocket carrying the satellites into orbit launched from Baikonur at 06:36:49 UTC Friday, July 14, 2017.   Shortly after launch both satellites were contacted from ground stations in Svalbard and Vardo, Norway. Both satellites are healthy based on initial telemetry, and commissioning is underway.   The first satellite

Darker colors are colder, and brighter colors are warmer, so the rift between the iceberg and the ice shelf appears as a thin line of slightly warmer area.

Wallace Joins Rovco as CTO

U.K.-based subsea company Rovco has appointed Dr. Iain Wallace o its senior management team as chief technology officer (CTO).   A former technical lead for the European Space Agency, Wallace will drive the development of a real-time 3D vision system for ROVs and AUVs. He will also explore how artificial intelligence can be used to solve asset integrity issues by extracting actionable information from traditional video survey data.   As CTO, he will enhance Rovco’s underwater photogrammetric 3D modeling capabilities utilizing the latest simultaneous location and mapping (SLAM)

Maritime Surveillance Drone Testing to Begin this Summer

The AR5 Life Ray UAS, developed by TEKEVER, has been selected by the European Space Agency (ESA) and the European Maritime Safety Agency (EMSA) to demonstrate the first European maritime surveillance system where drones are integral to operations. The first demonstration will be performed this summer over the Maltese waters of the Mediterranean sea, said Pedro Sinogas, TEKEVER CEO, at the AUVSI Xponential show in New Orleans, La.   Maritime operations have been brought into focus in Europe by the unprecedented migrant crisis. As part of the response to this crisis the EU border patrol agency

Evolution of Ocean Exploration: Mapping the Seafloor with Geodesy

the Scripps Institution of Oceanography and Walter Smith from the National Oceanic and Atmospheric Administration (NOAA) have been using Earth’s gravity field data from the civilian and military satellite operators. By combining new radar altimeter measurements from satellites such as the European Space Agency’s (ESA) CryoSat-2 and NASA CNES Jason-1 with existing data, a global marine gravity model was constructed that is two times more accurate than previous models. The team of scientists included R. Dietmar Müller from the University of Sydney, EmmanuelGarcia of NOAA and Richard Francis

Preben Stroem, managing director of Subsea Valley, says Subsea Valley found its impetus when it was realized there was no vehicle for technology transfer akin to what the European Space Agency program (or Boston’s medical cluster or Silicon Valley have). Well-connected to Houston’s large Norwegian community, Stroem reveals a U.S. government grant to the University of Houston for the study of subsea issues will be unveiled at OTC in Houston.

These measurements are spotty and expensive to collect.   Researchers at the Plymouth Marine Laboratory, the University of Exeter, Institut Francais Recherche Pour L´Exploitation de la Mer (Ifremer), the European Space Agency (ESA) and a team of international collaborators are developing new methods that allow them to monitor the acidity of the oceans from space.   "We are pioneering these techniques so that we can monitor large areas of the Earth's oceans, allowing us to quickly and easily identify

New Map Exposes Previously Unseen Details of Seafloor

clues about the formation of the continents have emerged through the new map, which is twice as accurate as the previous version produced nearly 20 years ago.   Developed using a scientific model that captures gravity measurements of the ocean seafloor, the new map extracts data from the European Space Agency’s (ESA) CryoSat-2 satellite, which primarily captures polar ice data but also operates continuously over the oceans, and Jason-1, NASA’s satellite that was redirected to map the gravity field during the last year of its 12-year mission.   Combined with existing data and

Arctic Ocean Free of Ice in Summer Perhaps in a Few Years

Sea ice in the Arctic is disappearing at a far greater rate than previously expected according to latest dedicated satellite data. Preliminary results from the European Space Agency's CryoSat-2 probe indicate that 900 cubic kilometres of summer sea ice has disappeared from the Arctic ocean over the past year. This rate of loss is 50% higher than most scenarios outlined by polar scientists and suggests that global warming, triggered by rising greenhouse gas emissions, is beginning to have a major impact on the region. In a few years the Arctic ocean could be free of ice
