IHO Celebrates World Hydrography Day 2020

The focus of this year’s World Hydrography Day is the key role that hydrography can play in supporting autonomous technologies. This includes aerial, surface and underwater survey drones as well as autonomous ships. World Hydrography Day is an opportunity for the IHO and its 93 Member States to reaffirm their commitment to raising awareness of the importance of hydrography, and to continue to coordinate their activities. Autonomous technologies are nothing new: mariners have been using systems such as autopilots for decades. More recently, unmanned vessels such as wave gliders have helped make advances in ocean sciences. We are however witnessing increasing levels of... (read more)

Mapping Underwater Terrain with Bathymetric Lidar

Two Similar Projects in Different Parts of the World
High-resolution bathymetric surveys support aquaculture research and increase navigational safety. In a case study, Tim Webster reports how this is done at Cape John Peninsula in Canada. In the second one, Carol Lockhart describes the project in the Kingdom of Tonga, a Polynesian archipelago comprising 169 islands that stretches across approximately 800 kilometres in the South Pacific Ocean. Measuring water depth for nautical purposes dates back to ancient civilisations. As technology has evolved through the centuries, besides ship-based echo-sounding, remote monitoring and mapping of water bodies has become increasingly available via Lidar bathymetric surveys conducted by airborne systems. New coastal... (read more)

This Is How a Dual Mapping Survey Vessel Is Used for Bathymetric Surveying Services

H2H Geoscience Engineering (H2H) has announced a new contract with Albany Water Board, providing topographic and bathymetric surveying services for their two reservoirs – Alcove and Basic Creek in Albany County, New York. The Alcove reservoir has not had elevation-capacity tables updated since the 1930s, and no elevation-capacity tables for Basic Creek reservoir currently exist. The Albany Water Board has requested that an updated elevation-capacity table be measured for Alcove reservoir, and also created for Basic Creek reservoir. Dual Mapping Survey Vessel For this project, H2H will utilize its dual mapping survey vessel, stationed in Troy, NY, equipped with the... (read more)

Fugro Wins NOAA Contract for Shoreline Mapping Services

Fugro has signed a five-year Indefinite Delivery Indefinite Quantity (IDIQ) contract with the US National Oceanic and Atmospheric Administration (NOAA) to provide shoreline mapping services in support of the agency’s Coastal Mapping Program. Issued through NOAA’s National Geodetic Survey (NGS), this multi-year contract is NGS’s second consecutive award to Fugro for services such as the provision of aerial imagery, topobathymetric Lidar, and shoreline feature compilation. NGS uses these data to update NOAA nautical charts, define US territorial limits, support coastal management activities and perform inundation modelling. “Fugro is proud to continue working with NOAA to update and improve the nation’s...

MOSAiC Aerial Survey Campaigns Temporarily Suspended Because of Coronavirus

Polarstern Crew Continues to be Unaffected by the Corona Pandemic
The Norwegian government recently announced comprehensive measures to combat the spread of the coronavirus, effective immediately. As a result, all travellers to Norway from non-Nordic countries who do not have a residence permit will most likely have to immediately leave the country again or be placed in quarantine for 14 days. In response, and due to the highly dynamic development of the coronavirus pandemic, the MOSAiC project management has decided to temporarily suspend the aerial survey campaigns planned for this spring and based in the Svalbard archipelago, which is under Norwegian administration. There are currently three icebreakers underway in the Central... (read more)

Hydrographic Mapping is Critical for the Caribbean

It is a Service Provided Inconsistently by the Developed Nations
Considered paradise by the legions of tourists who visit each year, the Caribbean islands are developing states that struggle to maintain a delicate balance between economic expansion and environmental preservation. Hydrographic mapping, a critical element in achieving this equilibrium, has been a service provided inconsistently by the developed nations upon which many of the islands are still dependent. Affordable new geospatial technologies, however, offer Caribbean islands the opportunity to reduce their traditional reliance and assume greater control over their economies and natural resources.

Fugro Joins the Australian HydroScheme Industry Partnership Program

The Australian government has selected Fugro to join the HydroScheme Industry Partnership Program (HIPP) to increase Australia’s hydrographic industry capability. The panel of industry partners was chosen as part of a long-term strategy to ensure safe shipping routes, commercial ports and maritime approaches within the Australian Charting Area. Panel members will acquire marine environmental data to produce digital maps of Australia’s sea and coastal areas that will improve the safety of maritime vessels operating in Australia’s sea charting area, which covers 10% of the Earth’s surface. The partnership program of AUD150 million secures a sovereign capacity to produce hydrographic information... (read more)

Woolpert Starts Acquiring Bathymetric Lidar Data of Saint Lucia’s Coastal Zone

The Woolpert-GDS Joint Venture (JV) has been contracted to acquire topographic and bathymetric lidar data of the Caribbean island Saint Lucia’s entire landmass and coastal zone. The contract was signed under the World Bank’s Disaster Vulnerability Reduction Project (DVRP), which aims to measurably reduce vulnerability to natural hazards and climate change in Saint Lucia and the Eastern Caribbean Region. High-resolution, 3D lidar data has proved effective around the world in mapping and modelling landscapes and environments, helping policy-makers make informed decisions about how best to utilize resources to prepare for and recover from weather-related disasters. Flood Modelling According to a... (read more)

NOAA Hydrographic Community Prepares for Field Season

Once a year, the NOAA hydrographic community meets at the Field Procedures Workshop in the US to not only share information but have frank discussions about their challenges and the path forward in preparation for the upcoming hydrographic field season. “The Field Procedures Workshop is the single most important event of the year for NOAA’s hydrographic community,” said Rear Admiral Shep Smith, director of the Office of Coast Survey. “NOAA has become a global leader in hydrography because we use the full breadth of our community to continually refine our practices and adopt the best available technology and tools.“ Themes of...
