The Indian Ocean Bathymetric Compilation (IOBC) project, undertaken by Nippon Foundation / GEBCO Scholars, is focused on building a regional bathymetric data compilation, of all publically-available bathymetric data within the Indian Ocean region from 30\°N to 60\° S and 10\° to 147\° E. One of the objectives of this project is the creation of a network of Nippon Foundation / GEBCO Scholars working together, derived from the thirty Scholars from fourteen nations bordering on the Indian Ocean who have graduated from this Postgraduate Certificate in Ocean Bathymetry (PCOB) training program training program at the University of New Hampshire. The IOBC project has provided students a working example during their course work and has been used as basis for student projects during their visits to another Laboratory at the end of their academic year. This multi-national, multi-disciplinary project team will continue to build on the skills gained during the PCOB program through additional training. The IOBC is being built using the methodology developed for the International Bathymetric Chart of the Southern Ocean (IBCSO) compilation (Arndt et al., 2013). This skill was transferred, through training workshops, to further support the ongoing development within the scholar\’s network. This capacity-building project is envisioned to connect other personnel from within all of the participating nations and organizations, resulting in additional capacity-building in this field of multi-resolution bathymetric grid generation in their home communities.

An updated regional bathymetric map and grids of the Indian Ocean will be an invaluable tool for all fields of marine scientific research and resource management. In addition, it has implications for increased public safety by offering the best and most up-to-date depth data for modeling regional-scale oceanographic processes such as tsunami-wave propagation behavior amongst others.

The University of New Hampshire Summer Hydrographic Field Course conducted a hydrographic survey off the coast of Southern Maine (USA) during the summer of 2012. The MBES data were acquired using a Kongsberg EM 2040 operated both at 300 kHz and 400 kHz in normal mode (multisector) and short CW (70 \µs), positioned with an Applanix POS/MV (Ver. 4) and using Real-Time Kinematic corrections broadcast from a GNSS base station.

The survey team was composed of faculty, staff and students (5 GEBCO scholars) from 12 nations spanning the globe. The survey provided a unique learning opportunity and a interactive learning environment for sharing experiences and comparing a wide number of national hydrographic Standard Operating Procedures (SOPs) in the main framework of the International Hydrographic Organization (IHO) and National Oceanic and Atmospheric Administration - Office of Coast Survey (NOAA-OCS) standards.

The resulting high resolution bathymetry and backscatter products lead to the discovery of several interesting geological features that are currently under investigation. The survey area covers four square nautical miles (196 linear nautical miles of data acquisition) over a highly dynamic seafloor ranging in depth from zero to 35 meters, with 200\% approximate average coverage. Additionally, 17 grab samples and 21 underwater videos have been conducted for geological and biological seafloor characterization as a direct result of this survey. All soundings from this survey are adequate to supersede prior surveys in their common areas, and are recommended for use in chart update.

The proposed poster will highlight the bathymetry, backscatter, and geological features, including a V-shaped morphologic structure.
