How to Derive Shallow-water Bathymetry Measurements from Satellites

TCarta Marine, a provider of marine geospatial products, is commercializing a new technique to derive highly accurate shallow-water bathymetry measurements from NASA’s ICESat-2 satellite data. The new methodology is being developed with funding from the National Science Foundation (NSF). In 2018, NSF awarded the company a Phase 1 Small Business Innovation Research (SBIR) grant to commercialize new satellite-derived bathymetric (SDB) measurement technologies. Referred to as Project Trident, the research focused on leveraging Artificial Intelligence (AI) – machine learning and computer vision – to determine shallow-water seafloor depth in variable water conditions.

Danish Hydrographic Office Turns to GIS for Automated Maritime Charting

A Radical Update Was Needed
Denmark has challenging seascapes to map and chart. It has a rich history of nautical charting that dates back to the seventeenth century, and many of its navigational products for Greenland were created in the 1960s. When GPS started to gain prominence, a radical update was needed. Apart from its 42-mile land border with Germany, the peninsular country of Denmark, with its scores of bays, straits, and fjords,  is surrounded almost entirely by the North and Baltic Seas. Denmark is also composed of more than 400 islands, including the Faroe Islands, located in the Atlantic Ocean between the United Kingdom... (read more)

This Is How Airborne Multibeam Lidar Coastal Mapping in Paradise Is Done

Insights from the first commercial use of Fugro RAMMS
The Rapid Airborne Multibeam Mapping System, RAMMS, was developed over a period of three years before it was officially launched in the summer of 2018. Senior hydrographer Richard Goosen describes how Fugro used the system for coastal and nearshore mapping at the paradisal Turks and Caicos Islands. The Rapid Airborne Multibeam Mapping System, RAMMS, was developed over a period of three years before it was officially launched in the summer of 2018. Senior hydrographer Richard Goosen describes how Fugro used the system for coastal and nearshore mapping at the paradisal Turks and Caicos Islands. In July 2018, Fugro embarked on a large-scale project to map the Turks and Caicos Islands for the United Kingdom Hydrographic Office (UKHO). This landmark effort called for integrated, high-resolution bathymetric, topographic and orthoimage data sets to support nautical chart updates and coastal zone management activities. To achieve the sizeable bathymetric portion of... (read more)

'Check and double check your data before getting somebody else to check it for you’

7 Questions to Phil Payne, Survey Delivery Manager, UK Hydrographic Office
Phil Payne, survey delivery manager of the UK Hydrographic Office talks about hydrographic programmes to support blue economic growth, intentional projects and the use of lidar for charting purposes. "There will be a continued drive towards autonomy and automated processing.” Phil Payne, survey delivery manager of the UK Hydrographic Office talks about hydrographic programmes to support blue economic growth, intentional projects and the use of lidar for charting purposes. ”There will be a continued drive towards autonomy and automated processing.” Prior to his work with the UK Hydrographic Office (UKHO), Phil Payne spent 25 years in the Royal Navy as a hydrographic and meteorology specialist.

Fugro Starts Nearshore Site Characterisation Contract for Copenhagen Megaproject

Danish consulting firm COWI has awarded Fugro a nearshore geotechnical site investigation for CPH City & Port Development’s Lynetteholmen megaproject in Copenhagen. Fugro’s site investigation will be used to inform the detailed design of the new artificial island, which will cover approximately 275 hectares and increase the Danish capital’s landmass by around 2%. Fugro’s solution will acquire high-quality geotechnical data in shallow water depths from a single jack-up, and ensure fast and efficient data delivery via Fugro’s newly developed Gaia solution. Fugro began work in September this year with the mobilisation of the Skate 3 modular jack-up; the fieldwork is... (read more)

How Data Can Be Used To Support Safety In Inshore Waters

The Blue Marine Foundation, a charity dedicated to creating marine reserves and establishing sustainable models of fishing, has completed a 'Big Data' project which sought to investigate how data can be used to support safety in inshore waters. The focus of the project “has been the current lack of collated and integrated data to effectively inform safety and risk at the coast and inshore waters”. OceanWise, marine data experts and provider of a range of intelligent marine data (mapping) products, has provided the mapping data for situational awareness and to allow multiple sources of data to be integrated using location as...

Sea-level Rise Could Affect Hundreds of Millions of People

Global vulnerability to sea-level rise is worse than previously understood, according to a report of Climate Central, an independent organization of leading scientists and journalists researching and reporting the facts about the changing climate and its impact on the public. Climate Central surveys and conducts scientific research on climate change and informs the public of key findings. New elevation data shows that by mid-century, frequent coastal flooding will rise higher than areas currently home to hundreds of millions of people, the report says.  As a result of heat-trapping pollution from human activities, rising sea levels could, within three decades, push chronic floods...

The Sun Shines on Nautical Charts in Different Ways

Just recently someone reminded me about the 20th anniversary of the finalization of the first official type-approval of an ECDIS device. Indeed, it was in summer 1999 that all sea trials and technical tests at the labs of the Federal Maritime and Hydrographic Agency of Germany were completed and, being in charge of this process at the time, I signed the official certificate to confirm that the Transas Navisailor device met all applicable IMO and IHO standards. We did our best to confirm software stability and physical robustness of the device based on the very small range of S-57 ENCs... (read more)

This is how Live Transmissions from the Deep are Done

Exploring the World’s Most Unknown and Least Protected Ocean
Live transmissions from unexplored regions deep below the Indian Ocean have underlined the role that reliable, high-speed broadband is playing at sea in expanding knowledge and promoting a more sustainable future. Live transmissions from unexplored regions deep below the Indian Ocean have underlined the role that reliable, high-speed broadband is playing at sea in expanding knowledge and promoting a more sustainable future. Increasing our knowledge of the marine fauna that populates the depths and the physical systems governing ocean behaviour is essential for a scientific community seeking to better understand climate change and assist political strategies to protect the underwater environment. The remote setting creates challenges for scientists in what are increasingly collaborative endeavours, involving multi-disciplinary teams that are disparately located. Furthermore, researchers often use advanced instruments that have never before... (read more)
