The History of Pursuing Hydrographic Measurement Accuracy

The profession of hydrographer is built upon measurement accuracy. Ever since Lucas Janszoon Waghenaer produced the first true nautical charts in 1584, hydrographers have been working to improve the accuracy of their measurements. For anyone fortunate enough to have reviewed Waghenaer’s atlas, the 'Spieghel der Zeevaert' (The Mariner’s Mirror), one of the first questions that comes to mind is how accurate are these charts? As the technology of the times was crude at best, it would be difficult to evaluate his charts by modern standards. However, two soundings stand out as indicative of both the relative accuracy of his data... (read more)

Applying Side-scan Sonar and an AI-powered Platform for Environmental Protection

Over the past few years, the University of Delaware, USA, has participated in a state programme which supports rescuing abandoned crab pots from the seabed and researches technologies to make the search process more effective. It has developed advanced sonar surveys from a boat with further map storage and processing in SPH Engineering’s ATLAS AI-powered platform. The evaluations proved to be time-effective and more accurate in comparison to the detections of human annotators.  Blue crab fishing is a popular commercial and recreational activity throughout the United States. In order to catch these crabs, people use 'crab pots'. These devices are placed... (read more)

This is NOAA’s Plan for Deep Ocean Mapping of US Waters

Identifying and Filling Gaps in Bathymetric Coverage Deeper Than 200m
NOAA is using a systematic approach to map all US waters in support of Seabed 2030 objectives and to contribute to the complete mapping of the world’s oceans in the next ten years. Mapping within US waters is a national goal that will only be accomplished through strong coordination and partnerships with other federal agencies, academia and the private sector. The Nippon Foundation - General Bathymetric Chart of the Oceans (GEBCO) Seabed 2030 project has revitalized international and national interest in ocean floor mapping (Smith, 2018). Across US oceans, coasts, and Great Lakes waters, the National Oceanic and Atmospheric Administration... (read more)

First Version of the Russian Wave Energy Web-atlas

Scientists from Lomonosov MSU (Faculty of Geography) have published the first version of the Russian wave energy web-atlas. The test version of the web-atlas posted at http://autolab.geogr.msu.ru/wavenergy in open access. It contains data on the wave energy spatial distribution in the Black, Caspian, Baltic, Barents and the Kara seas. The atlas also contains information on the basic parameters of wind waves. Energy Potential of the Wind and Waves Scientists started developing of the web-atlas in 2018. The basis of the atlas consists of unique data on the energy potential of the wind and waves obtained due to results of the original... (read more)

Growth in Maritime Industry to Drive Autonomous Underwater Vehicle Market

The autonomous underwater vehicle market is expected to be valued at US$371.3 in 2019. During the course of the forecast period (2018–2027), the market is expected to register a CAGR of over 6%, according to a recently launched report on the Autonomous Underwater Vehicle (AUV) market by Market Research, a research and consulting firm. AUVs are generally used in aquaculture systems for a variety of underwater tasks such as tank water monitoring in fish farming. Aquaculture production has been increasing rapidly, making fish farming one of the fastest growing industrial sectors across the world. This has been significantly contributing to the growth...

Map Shows Warming Waters Where Coral Reefs Could Be Under Threat

The ocean is increasingly becoming too hot to handle and coral reefs are suffering as a result, according to a recent publication on Mongabay, a website with news and inspiration from nature's frontline. Above-normal sea surface temperatures due to human-induced climate change are creating conditions that are stressing coral reefs, causing them to bleach, a phenomenon by which heat-stressed corals are forced to expel the symbiotic algae that provide them with nutrition, leaving them weak and ghostly white. If the heat stress persists for too long, reefs may never recover, and even die. A new interactive map has been made... (read more)
