NOAA Certifies San Francisco Bay Shipping Channel with Top Surveying Rating

There is a risk factor when navigating in and out of the busiest ports in the US, particularly at the helm of some of the world’s largest deep draft vessels. Mariners rely on tide and water level information, wind and weather data, but perhaps most importantly, they rely on electronic navigational charts and the quality of depth measurements that comprise them. Recently, NOAA’s Office of Coast Survey certified the US Army Corps of Engineers (USACE) hydrographic surveys for the Pinole Shoal Channel in San Francisco Bay. The Pinole Shoal Channel – a critical waterway for bulk carriers and tankers to... (read more)

What is the Physical Oceanographic Real-Time System?

Imagine you’re a port pilot, responsible for the safe passage of a cargo ship that’s about the same size as an aircraft carrier. It’s the middle of the night, it’s windy and you’re contending with large waves and an outgoing tide. A stressful scenario to be sure, but happily you have the benefit of a real-time information system that gives you details about water levels, currents, salinity and weather to help you guide your vessel. That system is known as PORTS, the Physical Oceanographic Real-Time System. Maritime Accidents The concept for PORTS was born following two serious maritime accidents in Tampa... (read more)

Were Tide Prediction Machines the First Analogue Computers?

In a research paper recently published in History of Geo- and Space Sciences, National Oceanography Centre (NOC) scientist Professor Philip Woodworth describes the history and basic principles of tidal prediction machines. Invented in around 1873, tidal prediction machines were analogue computers that provided an accurate and efficient means of predicting the ocean tide. Professor Woodworth: "Although only around 10% of the tidal prediction machines ever created were in operation at the Liverpool Tidal Institute, this paper demonstrates the central role of this institution, Arthur Doodson, and the UK more generally in this area of tidal science." Captain Scott's Discovery The present-day NOC... (read more)

New Environmental Monitoring Systems at Two Key Ghana Ports

OceanWise has recently been involved in a project with Ghana Ports and Harbours Authority (GPHA) – dubbed ´the trade and logistics hub of Western Africa´. The project involved installing a comprehensive environmental monitoring system at two key GPHA ports: Tema and Takoradi. The tide and weather system is designed to deliver essential real-time tide and weather data to the GPHA operators, hydrographers and pilots who will rely on the data to make important operational decisions and ensure safety at the port. The data from the tide and weather stations is collected, managed and published in the OceanWise data publishing platform... (read more)

People Living On Deltas Are Increasingly Vulnerable to Sea-level Rise

Researchers from Utrecht University in the Netherlands, Woods Hole Oceanographic Institution (WHOI) in the US, and colleagues found that delta areas worldwide have actually gained land in the past 30 years, despite river damming. However, recent land gains are unlikely to last throughout the 21st century due to expected, accelerated sea-level rise. The researchers published their findings in the journal Nature. Economically and Ecologically Valuable River deltas rank among the most economically and ecologically valuable environments on Earth. People living on deltas are increasingly vulnerable to sea-level rise and coastal hazards such as major storms, extremely high tides, and tsunamis.... (read more)

EuroSea Aims to Improve Ocean Observation

The UK-based National Oceanography Centre (NOC) joined an international consortium of 55 partners for the new EuroSea project. The 12.6 million euro, EU-funded project, aims to significantly improve ocean observation in Europe and beyond.  “The aim of the project is to better combine existing capacities in the European marine observing system, to fill existing gaps and to make the resulting data and information available to users more easily," says coordinator Dr. Toste Tanhua from the GEOMAR Helmholtz Centre for Ocean Research Kiel. NOC’s Prof. Kevin Horsburgh, Chief Scientist for International Development, is leading Work Package 5 (WP5) within the project:... (read more)

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...

‘Hydrography is Both a Science and a Technique’

7 Questions to the New Director General of the French Hydrographic Office
Chief weapons engineer Laurent Kerléguer was appointed director general of Shom, the French hydrographic office, in July 2019. In this interview, Hydro International asks him about the latest developments regarding the world of hydrography, climate change and artificial intelligence. “It’s becoming more urgent than ever to measure the ocean.” Chief weapons engineer Laurent Kerléguer was appointed director-general of Shom, the French hydrographic office, in July 2019. In this interview, Hydro International asks him about the latest developments regarding the world of hydrography, climate change and artificial intelligence. “It’s becoming more urgent than ever to measure the ocean.” Laurent Kerléguer was born in Brest, France, and has always lived by – or close to – the sea. Although he never had a ‘dream job’ as a child, he always had the feeling that his career would be linked to the sea. “For me as an engineer, hydrography is the perfect... (read more)

Global Sea-level Rise Has Been Accelerating Since 1960

The recent acceleration in global sea-level actually started in the 1960s, around three decades earlier than previously thought, according to a recent publication of the National Oceanography Centre (NOC). The results of the study form part of the NOC’s ongoing research into sea-level rise, which revealed last year that rising sea levels could cost £11 trillion worldwide annually by 2100, if the target of holding increasing global temperatures within 2ºC of pre-industrial levels is missed. The findings have been published in the Nature Climate Change journal and involve NOC scientists. Led by the University of Siegen in Germany, this study is the first to put... (read more)

Lost 52 Project Discovers the Bow of WW II Submarine 'Grunion'

Video Included
Tim Taylor and his team of the Lost 52 Project have identified the bow of the USS Grunion. It was discovered about a quarter of a mile from the main wreckage. In October 2018, the Lost 52 Project team returned to the site of the main wreck and found that the ship's bow had slid down a steep volcanic embankment. The submarine went missing about a month after it departed on its first war patrol in 1942. It wasn't seen again until the sons of the Grunion's commanding officer began searching for it and found the wreckage in 2007 off the... (read more)
