Data were collected by the GEBCO-Nippon Foundation Alumni Team, competing in the Shell Ocean Discovery XPRIZE, during the Final Round of the competition. Data acquisition was conducted by the means of unmanned vehicles only. The mapping system was composed of a single deep water AUV (Autonomous Underwater Vehicle), equipped with a high-resolution synthetic aperture sonar HISAS 1032 and multibeam echosounder EM 2040, partnered with a USV (Unmanned Surface Vessel). The USV provided positioning data as well as mapping the seafloor from the surface, using a hull-mounted multibeam echosounder EM 304. Bathymetry and imagery data were collected for 24 h and then processed for 48 h, with the extensive use of cloud technology and automatic data processing. Finally, all datasets were combined to generate a ...

A race for the prize has accelerated the development of innovative seabed mapping approaches that concentrated on new systems engineering or cutting-edge and innovative methods of existing equipment exploitation. The GEBCO - Nippon Foundation (NF) Alumni Team’s entry is presented in details as a state of the art example of mature and robust oceanmapping solution utilizing a high degree of autonomy and providing the possibilities of deepocean mapping that were unattainable before.

The Team is advised and mentored by selected GEBCO and industry experts, specialized in ocean mapping, geology, software development and naval architecture. The Team is distinguished by its extraordinary diversity with a global distribution of representatives from academic institutions, offshore survey and technology industries, as well as national hydrographic offices. A newly designed, innovative Unmanned Surface Vessel (USV), called SEA-KIT, will be built to cooperate with any Autonomous Underwater Vehicle (AUV) acting as the remote surface access to the deep ocean. The major role of the SEA-KIT in the competition design is 1) the transportation of a commercially available AUV to and from the land launch...

This international team is made up of industry experts, advisors from within the GEBCO community and broader ocean community and is led by alumni from the Nippon Foundation / GEBCO Graduate Certificate Ocean Mapping Training Program at the Centre for Coastal and Ocean Mapping / Joint Hydrographic Center (CCOM/JHC) of the University of New Hampshire. The Team is distinguished by its extraordinary diversity with a global distribution of representatives from academic institutions, offshore survey and technology industries, academia as well as national hydrographic offices. The alumni worked closely with partners such as Hushcraft Ltd., Ocean Floor Geophysics Inc., Earth Analytic and Teledyne CARIS as well as equipment supplier Kongsberg Maritime AS to develop and advance the Team concept created for the Shell Ocean Discovery XPRIZE.

Following a three-day workshop (14th to 16th July, 2015), four Nippon Foundation GEBCO students stayed at NOAA for an additional 10-day training at Office of Coast Survey’s Marine Chart Division. The key objective of the NOAA Chart Adequacy Workshop was to demonstrate techniques to evaluate the suitability of nautical chart products using chart quality information and publicly-available information. The attendees were cartographers, hydrographers and potential chart producers from hydrographic offices and government agencies around the world. The nations of the participants in the workshop included: Indonesia, Israel, Japan, Kenya, Malaysia, Philippines, South Korea, Sri Lanka, United Kingdom, United States and Venezuela. Through instructor presentations and GIS laboratory exercises (provided by Dr. Shachak Pe’eri and Lt Anthony Klemm), the participants generated the key layers that are in...

The Team was initiated and led by alumni of the Nippon Foundation / GEBCO training program at the University of New Hampshire. The alumni worked closely with international partners and suppliers to develop and advance their concept created for the Shell Ocean Discovery XPRIZE. The Shell Ocean Discovery XPRIZE competition aimed to push the boundaries of ocean technologies by creating solutions to the grand challenge of mapping our oceans. The Shell Ocean Discovery XPRIZE challenge was to develop a complete system that could map 100 km2 in 16 hours at 5 m horizontal resolution grid and produce images the elicited excitement in the general public. The designated survey area for the XPRIZE challenge could be up to 50 nautical miles offshore and operations had to be remotely coordinated from a land-based operation center. The entire mapping system had to fit into a standard ...

This is necessary for the correct modeling of ray bending. It is assumed that the sound speed layers are horizontal and static, according to the sound speed profile traditionally used in the depth calculation. In fact, the boundaries between varying water masses can be curved and oscillate. It is difficult to assess the parameters of these movements based on the sparse sampling of sound velocity profiles (SVP) collected through a survey; thus, alternative or augmented methods are needed to obtain information about water mass stratification for the time of a particular ping or a series of pings. The process of water column data collection and analysis is presented in this paper. The proposed method updates the sound speed profile by the automated detection of varying water mass boundaries, giving the option to adjust the SVP for each bea...
